The present invention is also directed to methods of prevention or treatment of a cholesterol-associated tumor in patients who are either at risk of developing a cholesterol-associated tumor or already exhibit a cholesterol-associated tumor. The tumor may be either a benign or a malignant tumor of the prostate, breast, endometrium or colon. The compounds of the invention may be co-administered with at least one other anticancer agent, which may be a steroidal antiandrogen, a non-steroidal antiandrogen, an estrogen, diethylstilbestrol, a conjugated estrogen, a selective estrogen receptor modulator (SERM), a taxane, or an LHRH analog. Tests showing the efficacy of the therapy and the rationale for combination therapy are presented in PCT application WO 2004/010948, the disclosure of which is incorporated herein by reference.

The compounds of the invention may reduce both cholesterol levels in vivo and epoxycholesterol formation and thereby inhibit initiation and progression of benign and malignant cholesterol-associated tumors or cholesterol-associated cell growth or cell-masses. Compositions disclosed herein, for example, are useful for the treatment and/or prevention of benign prostatic hypertrophy, as well as tumors associated with prostate, colon, endometrial, or breast tissues.

Compositions of the invention comprise an effective dose or a pharmaceutically effective amount or a therapeutically effective amount of a compound described above and may additionally comprise at least one other anticancer agent, for the treatment or prevention of benign prostatic hypertrophy or other cholesterol-related benign or malignant tumors, particularly those associated with prostate, breast, endometrial or colon tissues. Examples of agents for use in compositions and methods of the invention include steroidal or non steroidal antiandrogens such as finasteride (PROSCAR®), cyproterone acetate (CPA), flutamide(4′-nitro-3′-trifluorormethyl isobutyranilide), bicalutamide (CASODEX®), and nilutamide; estrogens, diethylstilbestrol (DES); conjugated estrogens (e.g., PREMARIN®); selective estrogen receptor modulator (SERM) compounds such as tamoxifen, raloxifene, droloxifene, idoxifene; taxanes such as paclitaxel (TAXOL®) and docetaxel (TAXOTERE®); and LHRH analogs such as goserelin acetate (ZOLADEX®), and leuprolide acetate (LUPRON®).

Methods of the invention parallel the compositions and formulations. The methods comprise co-administering to a patient in need of treatment a therapeutically effective amount of a compound of the present invention and one or more of: (a) a steroidal or non steroidal antiandrogen; (b) an estrogen; (c) diethylstilbestrol (DES); (d) a conjugated estrogen; (e) a selective estrogen receptor modulator (SERM); (f) a taxane; and (g) an LHRH analog. The term “selective estrogen receptor modulator” includes both estrogen agonist and estrogen antagonists and refers to compounds that bind with the estrogen receptor, inhibit bone turnover and prevent bone loss. In particular, estrogen agonists are compounds capable of binding to the estrogen receptor sites in mammalian tissue and mimicking the actions of estrogen in that tissue. Estrogen antagonists are compounds capable of binding to the estrogen receptor sites in mammalian tissue and blocking the actions of estrogen in that tissue. SERMs include, but are not limited to: tamoxifen (U.S. Pat. No. 4,536,516); 4-hydroxytamoxifen (U.S. Pat. No. 4,623,660); raloxifene (U.S. Pat. No. 4,418,068); idoxifene (U.S. Pat. No. 4,839,155; and droloxifene. For the taxanes see U.S. Pat. Nos. 6,395,770; 6,380,405; and 6,239,167. Compounds of the invention may also be combined with a steroidal or non steroidal antiandrogen, as described above.

Certain compounds of the invention may have the additional advantage that they suppress serum cholesterol and/or LDL levels while themselves not being appreciably absorbed into the mammalian circulation upon oral administration. As a result of the low-to-insignificant serum levels, fewer side-effects, such as drug-drug interactions, are observed.

The compositions and therapeutic methods described herein are useful for treating any condition for which a cholesterol absorption inhibitor is indicated. When administered to a patient, the compositions and pharmaceutical formulations described herein can lead to one or more of: reduced blood plasma or serum concentrations of low-density lipoprotein cholesterol (LDL-C); reduced blood plasma or serum concentrations of very low-density lipoprotein cholesterol (VLDL-C); reduced blood plasma or serum concentrations of intermediate-density lipoprotein cholesterol (IDL-C); reduced concentrations of cholesterol and cholesterol ester in the blood plasma or serum; reduced blood plasma or serum concentrations of apolipoprotein B; reduced blood plasma or serum concentrations of triglycerides; increased clearance of triglycerides; increased blood plasma or serum concentrations of high density lipoprotein cholesterol (HDL-C); reduced blood plasma or serum concentrations of non high-density lipoprotein cholesterol (non HDL-C); reduced levels of lipoprotein(a) (Lp(a)); increased ratio of HDL-C to LDL-C; inhibition of saponified and/or non-saponified fatty acid synthesis; reduced blood plasma or serum concentrations apolipoprotein C-II; reduced blood plasma or serum concentrations apolipoprotein C-DI; increased blood plasma or serum concentrations of HDL associated proteins (including but not limited to apo A-I, apo A-II, apo A-IV, and apo E), and increased fecal excretion of cholesterol.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more blood modifiers, anti-hypertensive agents, dyslipidemic agents, peptides which mitigates one or more symptoms of atherosclerosis, other agents, including combinations thereof) to prevent or treat vascular conditions and associated thrombotic events as described, for example, in US20020147184. Vascular diseases and conditions are often associated with thrombotic events sometimes resulting in myocardial infarction, stroke and ischemic attack. A thrombotic event is one associated with the formation or presence of a thrombus (e.g. blood clot). Thrombotic events include but are not limited to arterial thrombosis, coronary thrombosis, heart valve thrombosis, coronary stenosis, stent thrombosis and graft thrombosis. Blood clots associated with thrombic events result from an aggregation of blood factors, primarily platelets and fibrin with entrapment of cellular elements and frequently cause vascular obstruction at the point of their formation. Blood coagulation is a process consisting of a complex interaction of various blood components, or factors, which eventually gives rise to a fibrin clot. It is often desirable to selectively block or inhibit the coagulation cascade in subjects at risk for or exhibiting a vascular disease or condition with blood modifiers e.g. heparin, coumarin, derivatives of coumarin, indandione derivatives, thrombin inhibitors, factor Xa inhibitors, or other agents. For example, in the case of atherosclerosis, proliferation of smooth muscle cells (SMCs) in the vessel wall is an important event in the formation of vascular lesions after vascular reconstruction or in response to other vascular injury. SMC proliferation typically occurs within the first few weeks and up to six months after injury. Thrombosis and or SMC proliferation are also involved in restenosis, which is the re-occlusion of the blood vessel or valve after surgical treatment e.g. angioplasty or bypass grafts. Thus, the compounds and pharmaceutical formulations described herein can be used to prevent or treat restenosis. The compounds and pharmaceutical formulations described herein can also be used to improve coagulation homeostasis (including reducing plasminogen activating inhibitor (PAI)-I activity, reducing fibrinogen, managing high levels of fibrinogen, promoting fibrinolysis, and/or reducing platelet aggregation, and/or improving endothelial function). The compounds and pharmaceutical formulations described herein can used as coatings on surgical devices (e.g., catheters) and implants (e.g., stents) to reduce the risk of restenosis and thrombosis associated with invasive procedures used in the treatment of cardiovascular diseases.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more anti-hypertensive agents, dyslipidemic agents, peptides which mitigates one or more symptoms of atherosclerosis, other agents, including combinations thereof) to prevent or treat vascular (e.g. cardiovascular, cerebrovascular, peripheral vascular, renovascular disease, mesenteric vascular, pulmonary vascular disease, ocular vascular) inflammation in a subject in need of such treatment, for example, as described in US200301 19757 and to reduce blood plasma or serum concentrations of C-reactive protein (CRP) in a subject in need of such treatment, for example, as described in US200301 19757. Vascular inflammation can lead to atherosclerosis or coronary heart disease. Atherosclerosis is often indicated by a thickening and build-up of plaque in the arteries and typically occurs when the innermost layer of an artery, the endothelium, becomes damaged by cholesterol, toxins, oxidants, infectious agents and the like. The damaged endothelial cells in the artery walls produce adhesion molecules that allow white blood cells to accumulate in the vessel wall. Fats and cholesterol also build-up with the white blood cells causing inflammation of the artery. Such build-up can thicken to a point where the artery becomes vulnerable to blockage from a clot resulting in heart attack or stroke. The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy to slow the progression or cause regression of atherosclerotic plaques or lesions in, for example, coronary arteries, carotid arteries, the peripheral arterial system. Vascular inflammation often precedes the development and the continual process of atherosclerotic coronary heart disease. Vascular inflammation, beginning with an injury or change in the endothelial wall of the artery, may cause an alteration in the intimal layer that increases platelet adhesion to the endothelium. Vascular stimuli to mammals, e.g. cellular injury or inflammation, may lead to the production of various proteins, commonly called acute response proteins, in the body. CRP (C-reactive protein) is an acute response protein. Manufactured in the liver and deposited in damaged tissue, CRP is found in high levels in inflammatory fluids and in both the intimal layer of the atherosclerotic artery and within the lesions of atherosclerotic plaque. Studies have shown a positive association between CRP and coronary artery disease. For example, in a survey of 388 British men aged 50-69, the prevalence of coronary artery disease increased 1.5 fold for each doubling of CRP level (Mendall et al. (1996) BMJ. 312:1061-1065). Multiple prospective studies have also demonstrated that baseline CRP is a good marker of future cardiovascular events (Riker et al. 1998. J Investig Med. 46:391-395). Patients with CRP levels greater than about 0.4 mg/dL have been reported as having increased vascular inflammation and increased risk for vascular disease as compared to patients with levels less than 0.4 mg/dL. (L. Gruberb, “Inflammatory Markers in Acute Coronary Syndromes: C-reactive Protein (CRP) and Chlamydia”, American Heart Assoc. Scientific Sessions 2000). Patients with levels greater 3.4 mg/dL of c-reactive protein were reported to be in the highest quartile of risk. Patients in the second quartile (0.4 to 1.0 mg/dL of c-reactive protein) and third quartile (1.0 to 3.4 mg/dL of c-reactive protein) also have increased risk of vascular disease as compared to patients in the lowest quartile (<0.4 mg/dL c-reactive protein). CRP assays and methodologies for the same are available from Dade Behring Inc., Deerfield, Hi. Methods for analyzing CRPs are described, for example, in U.S. Pat. No. 5,358,852, U.S. Pat. No. 6,040,147, U.S. Pat. No. 6,277,584, and US20030 119757.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more agents used to treat Alzheimer's disease, other agents, including combinations thereof) to prevent, treat, or ameliorate symptoms of Alzheimer's Disease (AD), regulate production or levels of at least one amyloid β (Aβ) peptide and/or regulate the amount of ApoE isoform 4 in the bloodstream and/or brain of a subject, for example, as described in US20030 13699 and U.S. Pat. No. 6,080,778. The compositions can be administered to a subject that exhibits no symptoms of AD, has AD, has a family history of AD or dementia illness, is a human, is a human and has trisomy 21 (Down's syndrome), is a human and carries one or more mutations in the genes that encode β amyloid precursor protein (presenilin-1 or presinilin-2), is a human and carries the Apolipoprotein E isoform 4 gene, is a human and is greater than about 40 years of age, is a human and is greater than about 60 years of age. The subject can have an elevated blood cholesterol level, a total serum cholesterol level that is at least about 200 mg/dl, a total low density lipoprotein (LDL) level that is greater than about 100 mg/dl. Li some circumstances, the subject has an elevated level of at least one Aβpeptide in the bloodstream and/or brain. In various circumstances, the subject has an elevated level of Aβ-42 in the bloodstream and/or brain, has a level of Aβ-42 peptide greater than about 30 pM in the bloodstream, has a level of Aβ-42 peptide greater than about 40 pM in the bloodstream, has a level of Aβ-42 peptide ranging from about 30 pM to about 80 pM in the bloodstream, has a level Aβ-42 peptide of greater than about 50 pmol/gram of wet brain tissue. In various circumstances, the subject has a level of Aβ-40 peptide greater than about 200 pM in the bloodstream, has a level of Aβ-40 peptide greater than about 400 pM in the bloodstream, has a level of Aβ-40 peptide ranging from about 200 pM to about 800 pM in the bloodstream, has a level of Aβ-40 peptide greater than about 10 pmol/gram of wet brain tissue. In certain circumstances, the subject's level of Aβ peptide in the bloodstream is reduced from about 10 to about 100 percent from a level of Aβ peptides prior to administration of a composition of the present invention.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more anti-obesity agents, other agents, including combinations thereof) to prevent or treat obesity in a subject in need of such treatment, for examples as described in US200301 19428. Obesity is a common medical problem in developed countries and is a risk factor for other illnesses, e.g. hypertension, diabetes, degenerative arthritis and myocardial infarction. Weight loss medications may be appropriate for use in selected patients who are obese or who are overweight with co-morbid conditions. One measure for defining obesity is known as a body mass index (BMI), which is weight in kilograms divided by height in meters squared. A BMI of 18.5 to 24.9 is generally classified as normal, a BMI of 25.0 to 29.9 is generally classified as overweight and a BMI of 30 or greater is generally classified as obese. Alternatively, obesity may be defined as the top percentile, e.g. 15 percent, of a population's weight for a given height. Such definitions of obesity, however, are not a measure of body composition and different people may have higher or lower levels of body fat or muscle mass for their height. Nevertheless, these definitions of obesity are useful characterizations for general populations of people.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents to prevent or decrease the incidence of xanthomas in a subject in need of such treatment, for example, as described in US200301 19809. Xanthomas are benign fatty tumors associated with the accumulation of fatty materials under the surface of the skin and are often associated with those who have high triglyceride and cholesterol levels. Xanthoma itself may be indicative of an underlying disease e.g. diabetes, primary biliary cirrhosis, some types of cancer, or hypercholesterolemia.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one more anti-diabetic agents, anti-hypertensive agents, dyslipidemic agents, peptides which mitigates one or more symptoms of atherosclerosis, other agents, including combinations thereof) to prevent or treat diabetes and associated conditions in a subject in need of such treatment, for example, as described in US200402 148 11. Diabetes mellitus, commonly called diabetes, refers to a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose, referred to as hyperglycemia. There are two major forms of diabetes: Type 1 diabetes (also referred to as insulin-dependent diabetes or IDDM) and Type 2 diabetes (also referred to as noninsulin dependent diabetes or NIDDM). Type 1 diabetes is the result of an absolute deficiency of insulin, the hormone that regulates glucose utilization. Type 1 diabetes has two forms: Immune-Mediated Diabetes Mellitus, which results from a cellular mediated autoimmune destruction of the 3 cells of the pancreas; and Idiopathic Diabetes Mellitus, which refers to forms of the disease that have no known etiologies. Type 2 diabetes is a disease characterized by insulin resistance accompanied by relative, rather than absolute, insulin deficiency. Premature development of atherosclerosis and increased rate of cardiovascular and peripheral vascular diseases are characteristic features of patients with diabetes. Diabetes and associated conditions include but are not limited to Type 1 diabetes, Type 2 diabetes, gestational diabetes mellitus (GDM), maturity onset of diabetes of the young (MODY), pancreatitis, polycystic ovarian disease, impaired glucose tolerance, insulin resistance, hyperglycemia, hyperinsulinemia, elevated blood levels of fatty acids or glycerol, obesity, Syndrome X, dysmetabolic syndrome and related diseases, diabetic complications (including retinopathy, neuropathy, nerphropathy) and sexual dysfunction. The conditions, diseases, and maladies collectively referenced to as “Syndrome X” or Dysmetabolic Syndrome (as detailed in Johanson, J. Clin. Endocrinol. Metab., 1997, 82, 727-734, and other publications) include hyperglycemia and/or prediabetic insulin resistance syndrome, and is characterized by an initial insulin resistant state generating hyperinsulinemia, dyslipidemia, and impaired glucose tolerance, which can progress to Type II diabetes, characterized by hyperglycemia, which can progress to diabetic complications.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one more agents used to treat autoimmune disorders, other agents, including combinations thereof) to prevent or treat at least one autoimmune disorder in a subject in need of such treatment, for example, as described (including the rationale for the therapy) in US20040092499. Autoimmune disorders include, but are not limited to: Alopecia Areata, Ankylosing Spondylitis, Antiphospholipid Syndrome, aplastic anemia, myelodysplastic syndromes, paroxysmal nocturnal hemoglobulinemia, pure red cell aplasia, chronic neutropenias, amegakaryocytic thrombocytopenia, antiphospholipid syndromes, autoimmune thrombocytopenia, autoimmune hemolytic syndromes, antiphospholipid syndromes, autoimmune gastritis, achlorhydria, Autoimmune Addison's Disease, Autoimmune Diabetes, Autoimmune Hemolytic Anemia, Autoimmune Hepatitis, Autoimmune chronic Hepatitis, Autoimmune hypophysitis, Autoimmune orchiditis, autoimmune ovarian failure, Behcet's Disease, Bullous Pemphigoid, Cardiomyopathy, Celiac Sprue-Dermatitis, Cicatrical pemphigoid, Chronic Fatigue Immune Dysfunction Syndrome (CFIDS), Chronic Inflammatory Demyelinating Polyneuropathy, Interstitial cystitis, Churg-Strauss Syndrome, Cicatricial Pemphigoid, CREST Syndrome, Cold Agglutinin Disease, Crohn's Disease, Dermatitis herpetiformis, Discoid Lupus, Drug-induced autoimmune disorders, Endometriosis, Epidermolysis bullosa acquisita, Essential Mixed Cryoglobulinemia, Fibromyalgia-Fibromyositis, Glomerulonephritis, Good Pasture Syndrome, Graft Versus Host Disease, Graves' Disease, Guillain-Barr, Hashimoto's Thyroiditis, Idiopathic Inflammatory Myopathies, Idiopathic Pulmonary Fibrosis, Idiopathic Thrombocytopenia Purpura (ITP), IgA Nephropathy, Insulin Dependent Diabetes, Juvenile Arthritis, Lichen Planus, Systemic Lupus Erythmatosus, Meniere's Disease, Metal-induced autoimmunity disorders, Mixed Connective Tissue Disease, Multiple Sclerosis, Myasthenia Gravis, Myocarditis, Myositis, Optic neuritis, Painless/postpartum thyroiditis, Peripheral nerve vasculitis, Pemphigus Foliaceus, Pemphigus Vulgaris, Pernicious Anemia, Polyarteritis Nodosa, Polychondritis, Polyglandular Syndromes, Polymyalgia Rheumatica, Polymyositis and Dermatomyositis, Postinfectious autoimmune disorders, Primary Agammaglobulinemia, Primary Biliary Cirrhosis, Psoriasis, Psoriatic Arthritis, Reactive Arthritis, Raynaud's Phenomenon, Reiter's Syndrome, Rheumatic Fever, Rheumatoid Arthritis, Sarcoidosis, Scleritis, Scleroderma, Sjogren's Syndrome, Stiff-Man Syndrome, Takayasu Arteritis, Temporal Arteritis/Giant-cell Arteritis, Ulcerative Colitis, Uveitis, Vasculitis, Vitiligo, Kawasaki Disease, and Wegener's Granulomatosis.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more chemotherapeutic agents, anti-cancer agents, other agents, including combinations thereof) to prevent or treat cholesterol associated tumors in patients who are either at risk of developing a cholesterol-associated tumor or already exhibit a cholesterol associated tumor, for example, as described in US200401 16358. The compounds of the invention may reduce both cholesterol levels in vivo and epoxycholesterol formation and thereby inhibit initiation and progression of benign and malignant cholesterol-associated tumors or cholesterol-associated cell growth or cell-masses. The tumors may be benign cholesterol-associated tumors or cholesterol-associated cell growth or cell-masses including but not limited to benign tumors associated with prostate, colon, endometrial, or breast tissues or prostate, colon, breast, or endometrial cancer. Thus the compounds and pharmaceutical formulations described herein, for example, are useful to prevent or treat benign prostatic hypertrophy. The tumors may be malignant cholesterol-associated tumors or cholesterol-associated cell growth or cell-masses including but not limited to malignant tumors associated with prostate, colon, endometrial, or breast tissues or prostate, colon, breast, or endometrial cancer.

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. one or more chemotherapeutic agents, anti-cancer agents, other agents, including combinations thereof) for one or more of: inhibiting the expression of at least one multiple (“multi”)-drug resistance gene or protein in an animal cell, enhancing the effectiveness of a chemotherapeutic agent in an animal having cancer, and reversing a multi-drug resistance phenotype exhibited by an animal cell all of which are, for example, described in WO05/030225. Co-administration (though not necessarily concurrent or proximal consecutive) of cholesterol absorption inhibitors and chemotherapeutic agents can inhibit the expression of multi-drug resistance genes. Thus the compounds and pharmaceutical formulations described herein can be used alone or in combination therapy in one or more of: a) treating or alleviating a cancer; b) preventing, treating or alleviating tumour growth; c) inhibiting or reducing the expression of one or more multiple drug resistance genes; d) inhibiting or reducing the production of one or more proteins expressed by multiple drug resistance genes; e) enhancing the effectiveness of a chemotherapeutic agent in treating a cancer; and f) sensitizing a cell to one or more chemotherapeutic agents. Multiple drug resistance genes include but are not limited to ABCB1 (MDR-I), ABCA2 (ABC2), ABCB2 (TAP), ABCB3 (TAP), ABCC1 (MRP-I), and ABCC3 (MRP-3).

The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy with one or more additional agents (e.g. dyslipidemic agents, anti-diabetic agents, anti-hypertensive agents, anti-obesity agents, agents used to treat autoimmune disorders, agents used to treat demylenation and its associated disorders, agents used to treat Alzheimer's disease, blood modifiers, hormone replacement agent/compositions, chemotherapeutic agents, peptides which mitigate one or more symptoms of atherosclerosis, anti-cancer agents, agents used to treat bone loss and associated disorders, other agents, including combinations thereof) to modulate lipid raft structure (for example by reducing the level of cholesterol in the lipid raft), for example, as described (including the related rationale) in WO05023305. Lipid rafts are discrete microdomains in the plasma membrane which are rich in sphingolipids and contain ordered cholesterol (Field et al., J. Biol. Chem., 1997, 272, 4276-4280). In a number of cells, it has become clear that certain membrane associated proteins preferentially partition into these lipid rafts (Foster, de Hoog and Mann, PNAS, 2003, 100, 5813-8). These include various seven transmembrane domain receptors and their associated G proteins and various proteins that are attached to the inner membrane leaflet through lipid moieties such as prenylation, including small molecular weight G proteins, such as Ras, Rac, cdc42 and Rho. Disruption of lipid rafts results in an uncoupling of efficient signal transduction through receptors such as G protein coupled receptors, the T cell receptor and the high affinity IgE receptor. Compounds which modulate lipid raft structure may be useful in the treatment or prophylaxis of a wide variety of diseases and conditions. The compounds and pharmaceutical formulations described herein can be used alone or in combination therapy to prevent or treat a disease or condition associated with lipid raft structure such as respiratory tract/obstructive airways diseases and disorders (including: acute-, allergic, hatrophic rhinitis or chronic rhinitis (such as rhinitis caseosa, hypertrophic rhinitis, rhinitis purulenta, rhinitis sicca), rhinitis medicamentosa, membranous rhinitis (including croupous, fibrinous and pseudomembranous rhinitis), scrofulous rhinitis, perennial allergic rhinitis, seasonal rhinitis (including rhinitis nervosa (hay fever) and vasomotor rhinitis), antitussive activity, asthma (such as bronchial, allergic, intrinsic, extrinsic and dust asthma particularly chronic or inveterate asthma (e.g. late asthma and airways hyper-responsiveness)), bronchitis (including chronic and eosinophilic bronchitis), emphysema, chronic inflammatory diseases of the lung which result in interstitial fibrosis, such as interstitial lung diseases (ELD) (e.g., idiopathic pulmonary fibrosis, or ILD associated with rheumatoid arthritis, or other autoimmune conditions), chronic obstructive pulmonary disease (COPD)(such as irreversible COPD), chronic sinusitis, conjunctivitis (e.g. allergic conjunctivitis), cystic fibrosis, fanner's lung and related diseases, fibroid lung, hypersensitivity lung diseases, hypersensitivity pneumonitis, idiopathic interstitial pneumonia, nasal congestion, nasal polyposis, otitis media, and chronic cough associated with inflammation or iatrogenic induced); systemic anaphylaxis or hypersensitivity responses (such as drug allergies (e.g., to penicillin, cephalosporins), insect sting allergies, pet allergies, house dust mite allergies, pollen allergies, and food related allergies which may have effects remote from the gut (such as migraine, rhinitis and eczema)); gastro-intestinal diseases and disorders (such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), Crohn's disease, ulcerative colitis, gastric and duodenal ulceration), Fabry's disease; Kimura's disease; multiple sclerosis; wound healing; liver hepatitis and cirrhosis; rheumatoid arthritis; juvenile rheumatoid arthritis; systemic lupus erythematosus; degenerative joint disease; connective tissue diseases; ankylosing spondylitis; soft tissue rheumatism (e.g. tendonitis, bursitis); Sjogren's syndrome; psoriasis; psoriatic arthritis; neuralgia; synovitis; glomerulonephritis; vasculitis; sacoidosis; inflammations that occur as sequellae to influenza; the common cold and other viral infections; gout; pseudogout; contact dermatitis; low back and neck pain; dysmenorrhea; headache; dementias; toothache; sprains; strains; myositis; burns; injuries; pain and inflammation that follows surgical and dental procedures in a patient; Parkinsons disease; muscular dystrophy; neoplasia; hyperparathyroidism; sepsis and septic shock; infections by intracellular pathogens (including, for example, bacteria (such as Salmonella, Chlamydiae, listeria, Mycobacteria tuberculosis), viruses (such as HIV, Measles virus, Papilloma viruses, Epstein-Barr virus, Respiratory Syncytial Virus (RSV), Hepatitis, Herpes viruses, Influenza virus, Ebola and Marburg viruses), parasites (such as Plasmodium (malaria), leishmania, Trypanosoma (sleeping sickness), Toxoplasma gondii)); and bacterial infections including Shigella, Escherichia coli (including 0157), Campylobacter, Vibrio cholerae, Clostridium difficile and Clostridium tetani.

DEFINITIONS

Throughout this specification the terms and substituents retain their definitions.

Alkyl is intended to include linear, branched, or cyclic hydrocarbon structures and combinations thereof. When not otherwise restricted, the term refers to alkyl of 20 or fewer carbons. Lower alkyl refers to alkyl groups of 1, 2, 3, 4, 5 and 6 carbon atoms. Examples of lower alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, s- and t-butyl and the like. In certain embodiments the lower alkyl group is methyl. Preferred alkyl and alkylene groups are those of C₂₀or below (e.g. C₁, C₂, C₃, C₄, C₅, C₆, C₇, C₈, C₉, C₁₀, C_n, C₁₂, Ci₃, Ci₄, C₁₅, C₁₆, C₁₇, C₁₈, C₁₉, C₂₀).

Examples of cycloalkyl groups include c-propyl, c-butyl, c-pentyl, norbornyl, adamantyl and the like.

C₁to C₂₀Hydrocarbon (e.g. C₁, C₂, C₃, C₄, C₅, C₆, C₇, C₈, C₉, C₁₀, C₁₁, C₁₂, C₁₃, C₁₄, C₁₅, C₁₆, C₁₇, C₁₈, C₁₉, C₂₀) includes alkyl, cycloalkyl, alkenyl, alkynyl, aryl and combinations thereof. Examples include benzyl, phenethyl, cyclohexylmethyl, camphoryl and naphthylethyl. The term “phenylene” refers to ortho, meta or para residues of the formulae:

Alkoxy or alkoxyl refers to groups of 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms of a straight, branched, cyclic configuration and combinations thereof attached to the parent structure through an oxygen. Examples include methoxy, ethoxy, propoxy, isopropoxy, cyclopropyloxy, cyclohexyloxy and the like. Lower-alkoxy refers to groups containing one to four carbons. In certain embodiments the lower-alkoxy group is methoxy.

Oxaalkyl refers to alkyl residues in which one or more carbons (and their associated hydrogens) have been replaced by oxygen. Examples include methoxypropoxy, 3,6,9-trioxadecyl and the like. The term oxaalkyl is intended as it is understood in the art [see Naming and Indexing of Chemical Substances for Chemical Abstracts, published by the American Chemical Society, ¶196, but without the restriction of Tf127(a)], i.e. it refers to compounds in which the oxygen is bonded via a single bond to its adjacent atoms (forming ether bonds). Similarly, thiaalkyl and azaalkyl refer to alkyl residues in which one or more carbons have been replaced by sulfur or nitrogen, respectively. Examples include ethylaminoethyl and methylthiopropyl.

Polyol refers to a compound or residue having a plurality of —OH groups, as defined in Hawley's Condensed Chemical Dictionary. 12^thEdition, Richard J. Lewis, Sr.; Van Nostrand Reinhold Co. New York (1993). Polyols may be thought of as alkyls in which a plurality of C—H bonds have been replaced by C—OH bonds. More particularly, a polyol, also referred to as an alditol, is an alcohol of general formula CH₂OH(CH₂OH)_nCH₂OH, wherein n is 1 to 5. Common polyol compounds include for example glycerol, erythritol, sorbitol, xylitol, mannitol and inositol. Linear polyol residues will generally be of the empirical formula —C_yH_2y+iO_y, and cyclic polyol residues will generally be of the formula —C_yH_2y-1O_y. Those in which y is 3, 4, 5 and 6 are preferred. Cyclic polyols also include reduced sugars, such as glucitol.

Acyl refers to groups of 1, 2, 3, 4, 5, 6, 7 and 8 carbon atoms of a straight, branched, cyclic configuration, saturated, unsaturated and aromatic and combinations thereof, attached to the parent structure through a carbonyl functionality. One or more carbons in the acyl residue may be replaced by nitrogen, oxygen or sulfur as long as the point of attachment to the parent remains at the carbonyl. Examples include formyl, acetyl, propionyl, isobutyryl, ̂-butoxycarbonyl, benzoyl, benzyloxycarbonyl and the like. Lower-acyl refers to groups containing one to four carbons.

Aryl and heteroaryl refer to aromatic or heteroaromatic rings, respectively, as substituents. Heteroaryl contains one, two or three heteroatoms selected from O, N, or S. Both refer to monocyclic 5- or 6-membered aromatic or heteroaromatic rings, bicyclic 9- or 10-membered aromatic or heteroaromatic rings and tricyclic 13- or 14-membered aromatic or heteroaromatic rings. Aromatic 6, 7, 8, 9, 10, 11, 12, 13 and 14-membered carbocyclic rings include, e.g., benzene, naphthalene, indane, tetralin, and fluorene and the 5, 6, 7, 8, 9 and 10-membered aromatic heterocyclic rings include, e.g., imidazole, pyridine, indole, thiophene, benzopyranone, thiazole, furan, benzimidazole, quinoline, isoquinoline, quinoxaline, pyrimidine, pyrazine, tetrazole and pyrazole.

Arylalkyl means an alkyl residue attached to an aryl ring. Examples are benzyl, phenethyl and the like.

Substituted alkyl, aryl, cycloalkyl, heterocyclyl etc. refer to alkyl, aryl, cycloalkyl, or heterocyclyl wherein up to three H atoms in each residue are replaced with halogen, haloalkyl, hydroxy, loweralkoxy, carboxy, carboalkoxy (also referred to as alkoxycarbonyl), carboxamido (also referred to as alkylaminocarbonyl), cyano, carbonyl, nitro, amino, alkylamino, dialkylamino, mercapto, alkylthio, sulfoxide, sulfone, acylamino, amidino, phenyl, benzyl, heteroaryl, phenoxy, benzyloxy, or heteroaryloxy.

The term “halogen” means fluorine, chlorine, bromine or iodine.

The term “sugar” is used in its normal sense, as defined in Hawley's Condensed Chemical Dictionary, 12^thEdition, Richard J. Lewis, Sr.; Van Nostrand Reinhold Co. New York (1993). It encompasses any carbohydrate comprised of one or two saccharose groups. The monosaccharide sugars (often called simple sugars) are composed of chains of 2-7 carbon atoms. One of the carbons carries aldehydic or ketonic oxygen, which may be combined in acetal or ketal forms. The remaining carbons usually have hydrogen atoms and hydroxyl groups (or protecting groups for hydroxyl, such as acetate). Monosaccharides, which would be considered within the term “sugars” as intended in this application, include, but are not limited to, allose, altrose, gulose, idose, talose, arabinose, ribose, xylose, ribulose, xylulose, deoxyribose, galactose, glucose, mannose, fructose, sorbose, tagatose, fucose, quinovose, rhamnose, manno-heptulose and sedoheptulose. Disaccharides include, but are not limited to, sucrose, lactose, maltose, and cellobiose. Unless specifically modified, the general term “sugar” refers to both D-sugars and L-sugars. The sugar may also be protected. The sugar may be attached through oxygen (as in U.S. Pat. No. 5,756,470) or through carbon (as in PCT WO 2002066464), the disclosures of both of which are incorporated herein by reference. Sugars may also be indirectly attached to any aglycone that has a free phenol by the method of Kvεeraø, Werder, Hauser and Carreira “Carbohydrate Sulfonyl Chlorides for Simple, Convenient Access to Glycoconjugates” [Org. Lett. 7(6): 1145-48 (2005).], the disclosure of which is incorporated herein by reference. This method provides sugars linked via a sulfonate.

Reduced C-attached sugars or C-glycosyl compounds are also encompassed by the invention. The reduced sugars (e.g. glucitol) could be classified either as polyols or as sugars.

The term “glucuronide” is also used in its normal sense to refer to a glycoside of glucuronic acid.

The term “sugar carbamate” refers to mono-, di- and oligosaccharides in which one or more hydroxyls have been derivatized as carbamates, particularly as phenyl carbamates and substituted phenyl carbamates. [See Detmers et al. Biochim Biophys. Acta 1486, 243-252 (2000), which is incorporated herein by reference.] In certain embodiments the sugar carbamate is:

The term “prodrug” refers to a compound that is made more active in vivo. Commonly the conversion of prodrug to drug occurs by enzymatic processes in the liver or blood of the mammal. Many of the compounds of the invention may be chemically modified without absorption into the systemic circulation, and in those cases, activation in vivo may come about by chemical action (as in the acid-catalyzed cleavage in the stomach) or through the intermediacy of enzymes and microflora in the gastrointestinal GI tract.

It will be recognized that the compounds of this invention can exist in forms in which one isotope of a particular atom may be replaced with a different isotope of that same atom. For example, “hydrogen” may be ¹H, ²H or ³H; “carbon” may be ¹²C, ¹³C, or ¹⁴C; “nitrogen” may be ¹⁴N or ¹⁵N; “oxygen” may be ¹⁶0, ¹⁷O or ¹⁸O; and the like. It will be recognized that the compounds of this invention can exist in radiolabeled form, i.e., the compounds may contain one or more atoms containing an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Radioisotopes of hydrogen, carbon, phosphorous, fluorine, iodine and chlorine include 3H, ¹⁴C, ³⁵S, ¹⁸F, ³²P, ³³P, ¹²⁵I, and ³⁶Cl, respectively. Compounds that contain those radioisotopes and/or other radioisotopes of other atoms are within the scope of this invention. Tritiated, i.e. ³H, and carbon-14, i.e., ¹⁴C, radioisotopes are particularly preferred for their ease in preparation and detectability. Radiolabeled compounds of Formulae I-V of this invention and prodrugs thereof can generally be prepared by methods well known to those skilled in the art. Conveniently, such radiolabeled compounds can be prepared by carrying out the procedures disclosed in the Examples and Schemes by substituting a readily available radiolabeled reagent for a non-radiolabeled reagent.

The compounds of the invention can also exist in other labeled forms. U.S. Patent Publication No. 20020009714, the disclosure of which is herein incorporated by reference in its entierety, discloses methods of labeling and uses of labeled cholesterol absorption inhibitors. The labels can be primary labels (where the label comprises an element which is detected directly) or secondary labels (where the detected label binds to a primary label, e.g., as is common in immunological labeling). An introduction to labels, labeling procedures and detection of labels is found in Introduction to Immunocvtochemistry, (2d ed.) Polak and Van Noorden, Springer Verlag, N.Y. (1997) and in Handbook of Fluorescent Probes and Research Chemicals, Haugland (1996), a combined handbook and catalogue published by Molecular Probes, Inc., Eugene, Oreg. Primary and secondary labels can include undetected elements as well as detected elements. Useful primary and secondary labels in the present invention can include spectral labels, which include fluorescent labels such as fluorescent dyes (e.g., fluorescein and derivatives such as fluorescein isothiocyanate (FITC) and Oregon Green™, rhodamine and derivatives (e.g., Texas red, tetramethylrhodamine isothiocyanate (TRITC), etc.), digoxigenin, biotin, phycoerythrin, AMCA, CyDyes™ and the like), radiolabels (including those described above), enzymes (e.g., horseradish peroxidase, alkaline phosphatase etc.) spectral colorimetric labels such as colloidal gold or colored glass or plastic (e.g. polystyrene, polypropylene, latex, etc.) beads. The label may be coupled directly or indirectly to the compound of the invention according to methods well known in the art. As indicated above, a wide variety of labels may be used, with the choice of label depending on sensitivity required, ease of conjugation with the compound, stability requirements, available instrumentation, and disposal provisions. In general, a detector which monitors a protein/inhibitory agent interaction is adapted to the particular label which is used. Typical detectors include spectrophotometers, phototubes and photodiodes, microscopes, scintillation counters, cameras, film and the like, as well as combinations thereof. Examples of suitable detectors are widely available from a variety of commercial sources known to persons of skill.

Nonlimiting examples of labels include those which utilize 1) chemiluminescence (using horseradish peroxidase or alkaline phosphatase with substrates that produce photons as breakdown products) with kits being available, e.g., from Molecular Probes, Amersham, Boehringer-Mannheim, and Life Technologies/Gibco BRL; 2) color production (using both horseradish peroxidase or alkaline phosphatase with substrates that produce a colored precipitate) (kits available from Life Technologies/Gibco BRL, and Boehringer-Mannheim); 3) fluorescence (e.g., using Cy-5 (Amersham), fluorescein, and other fluorescent tags); 5) radioactivity. Other methods for labeling and detection will be readily apparent to one skilled in the art.

In one embodiment, the label is a fluorescent label. Fluorescent labels have the advantage of requiring fewer precautions in handling, and being amendable to high-throughput visualization techniques (optical analysis including digitization of the image for analysis in an integrated system comprising a computer). Preferred labels are typically characterized by one or more of the following: high sensitivity, high stability, low background, low environmental sensitivity and high specificity in labeling. Fluorescent moieties, which are incorporated into the labels of the invention, are generally are known, including Texas red, digoxigenin, biotin, 1- and 2-aminonaphthalene, p,p′-diaminostilbenes, pyrenes, quaternary phenanthridine salts, 9-aminoacridines, p,p′-diaminobenzophenone imines, anthracenes, oxacarbocyanine, merocyanine, 3-aminoequilenin, perylene, bis-benzoxazole, bis-p-oxazolyl benzene, 1,2-benzophenazin, retinol, bis-3-aminopyridinium salts, hellebrigenin, tetracycline, sterophenol, benzimidazolylphenylamine, 2-oxo-3-chromen, indole, xanthen, 7-hydroxycoumarin, phenoxazine, calicylate, strophanthidin, porphyrins, triarylmethanes, flavin and many others. Many fluorescent tags are commercially available from the SIGMA chemical company (Saint Louis, Mo.), Molecular Probes, R&D systems (Minneapolis, Minn.), Pharmacia LKB Biotechnology (Piscataway, N.J.), CLONTECH Laboratories, Inc. (Palo Alto, Calif.), Chem Genes Corp., Aldrich Chemical Company (Milwaukee, Wis.), Glen Research, Inc., GIBCO BRL Life Technologies, Inc. (Gaithersberg, Md.), Fluka ChemicaBiochemika Analytika (Fluka Chemie AG, Buchs, Switzerland), and Applied Biosystems (Foster City, Calif.), as well as many other commercial sources known to one of skill.

The labels may be covalently bound to the compounds of the invention by a tether group. The tether group can be any moiety capable of covalently linking to the inhibitors and to the labels. Preferred groups are substituted or unsusbstituted alkylene, alkenylene or alkynylene of 1 to 10 carbon atoms, more preferably 1 to 4 carbon atoms. Particularly preferred groups are unsusbstituted alkynylenes.

The terms “methods of treating or preventing” mean amelioration, prevention or relief from the symptoms and/or effects associated with lipid disorders. The term “preventing” as used herein refers to administering a medicament beforehand to forestall or obtund an acute episode or, in the case of a chronic condition to diminish the likelihood or seriousness of the condition. The person of ordinary skill in the medical art (to which the present method claims are directed) recognizes that the term “prevent” is not an absolute term. In the medical art it is understood to refer to the prophylactic administration of a drug to substantially diminish the likelihood or seriousness of a condition, and this is the sense intended in applicants' claims. As used herein, reference to “treatment” of a patient is intended to include prophylaxis. Throughout this application, various references are referred to. The disclosures of these publications in their entireties are hereby incorporated by reference as if written herein.

The term “mammal” is used in its dictionary sense. The term “mammal” includes, for example, mice, hamsters, rats, cows, sheep, pigs, goats, and horses, monkeys, dogs (e.g., Cardsfamiliaris), cats, rabbits, guinea pigs, and primates, including humans.

The compounds described herein contain two or more asymmetric centers and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms. Each chiral center may be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The present invention is meant to include all such possible isomers, as well as, their racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.

The graphic representations of racemic, ambiscalemic and scalemic or enantiomerically pure compounds used herein are taken from Maehr J₁Chem. Ed. 62, 114-120 (1985): solid and broken wedges are used to denote the absolute configuration of a chiral element; wavy lines and single thin lines indicate disavowal of any stereochemical implication which the bond it represents could generate; solid and broken bold lines are geometric descriptors indicating the relative configuration shown but denoting racemic character; and wedge outlines and dotted or broken lines denote enantiomerically pure compounds of indeterminate absolute configuration.

The term “enantiomeric excess” is well known in the art and is defined for a resolution of ab into a+b as

${ee}_{a} = (\frac{conc . of a - conc . of b}{conc . of a + conc . of b}) \times 10 \circ$

The term “enantiomeric excess” is related to the older term “optical purity” in that both are measures of the same phenomenon. The value of ee will be a number from 0 to 100, zero being racemic and 100 being pure, single enantiomer. A compound which in the past might have been called 98% optically pure is now more precisely described as 96% ee; in other words, a 90% ee reflects the presence of 95% of one enantiomer and 5% of the other in the material in question.

The configuration of any carbon-carbon double bond appearing herein is selected for convenience only and is not intended to designate a particular configuration; thus a carbon-carbon double bond depicted arbitrarily herein as E may be Z, E, or a mixture of the two in any proportion.

Terminology related to “protecting”, “deprotecting” and “protected” functionalities occurs throughout this application. Such terminology is well understood by persons of skill in the art and is used in the context of processes which involve sequential treatment with a series of reagents. In that context, a protecting group refers to a group which is used to mask a functionality during a process step in which it would otherwise react, but in which reaction is undesirable. The protecting group prevents reaction at that step, but may be subsequently removed to expose the original functionality. The removal or “deprotection” occurs after the completion of the reaction or reactions in which the functionality would interfere. Thus, when a sequence of reagents is specified, as it is in the processes of the invention, the person of ordinary skill can readily envision those groups that would be suitable as “protecting groups”. Suitable groups for that purpose are discussed in standard textbooks in the field of chemistry, such as Protective Groups in Organic Synthesis by T. W. Greene [John Wiley & Sons, New York, 1991], which is incorporated herein by reference. Particular attention is drawn to the chapters entitled “Protection for the Hydroxyl Group, Including 1,2- and 1,3-Diols” (pages 10-86).

The abbreviations Me, Et, Ph, Tf, Ts and Ms represent methyl, ethyl, phenyl, trifluoromethanesulfonyl, toluenesulfonyl and methanesulfonyl respectively. A comprehensive list of abbreviations utilized by organic chemists (i.e. persons of ordinary skill in the art) appears in the first issue of each volume of the Journal of Organic Chemistry. The list, which is typically presented in a table entitled “Standard List of Abbreviations” is incorporated herein by reference.

While it may be possible for the compounds of the invention to be administered as the raw chemical, it is preferable to present them as a pharmaceutical composition. According to a further aspect, the present invention provides a pharmaceutical composition comprising a compound of formula I-V or a pharmaceutically acceptable salt or solvate thereof, together with one or more pharmaceutically carriers thereof and optionally one or more other therapeutic ingredients. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.

The formulations include those suitable for oral, parenteral (including subcutaneous, intradermal, intramuscular, intravenous and intraarticular), rectal and topical (including dermal, buccal, sublingual and intraocular) administration. The most suitable route may depend upon the condition and disorder of the recipient. The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing into association a compound of formula I-V or a pharmaceutically acceptable salt or solvate thereof (“active ingredient”) with the carrier, which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers or both and then, if necessary, shaping the product into the desired formulation.

Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be presented as a bolus, electuary or paste.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, lubricating, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated so as to provide sustained, delayed or controlled release of the active ingredient therein.

The pharmaceutical compositions may include a “pharmaceutically acceptable inert carrier”, and this expression is intended to include one or more inert excipients, which include starches, polyols, granulating agents, microcrystalline cellulose, diluents, lubricants, binders, disintegrating agents, and the like. If desired, tablet dosages of the disclosed compositions may be coated by standard aqueous or nonaqueous techniques, “Pharmaceutically acceptable carrier” also encompasses controlled release means.

Compositions of the present invention may also optionally include other therapeutic ingredients, anti-caking agents, preservatives, sweetening agents, colorants, flavors, desiccants, plasticizers, dyes, and the like. Any such optional ingredient must, of course, be compatible with the compound of the invention to insure the stability of the formulation.

The dose range for adult humans is generally from 0.005 mg to 10 g/day orally. Tablets or other forms of presentation provided in discrete units may conveniently contain an amount of compound of the invention which is effective at such dosage or as a multiple of the same, for instance, units containing 5 mg to 500 mg, usually around 10 mg to 200 mg. The precise amount of compound administered to a patient will be the responsibility of the attendant physician. However, the dose employed will depend on a number of factors, including the age and sex of the patient, the precise disorder being treated, and its severity.

A dosage unit (e.g. an oral dosage unit) can include from, for example, 1 to 30 mg, 1 to 40 mg, 1 to 100 mg, 1 to 300 mg, 1 to 500 mg, 2 to 500 mg, 3 to 100 mg, 5 to 20 mg, 5 to 100 mg (e.g. 1 mg, 2 mg, 3 mg, 4 mg, 5 mg, 6 mg, 7 mg, 8 mg, 9 mg, 10 mg, 11 mg, 12 mg, 13 mg, 14 mg, 15 mg, 16 mg, 17 mg, 18 mg, 19 mg, 20 mg, 25 mg, 30 mg, 35 mg, 40 mg, 45 mg, 50 mg, 55 mg, 60 mg, 65 mg, 70 mg, 75 mg, 80 mg, 85 mg, 90 mg, 95 mg, 100 mg, 150 mg, 200 mg, 250 mg, 300 mg, 350 mg, 400 mg, 450 mg, 500 mg) of a compound described herein.

Combination therapy can be achieved by administering two or more agents, each of which is formulated and administered separately, or by administering two or more agents in a single formulation. Other combinations are also encompassed by combination therapy. For example, two agents can be formulated together and administered in conjunction with a separate formulation containing a third agent. While the two or more agents in the combination therapy can be administered simultaneously, they need not be. For example, administration of a first agent (or combination of agents) can precede administration of a second agent (or combination of agents) by minutes, hours, days, or weeks. Thus, the two or more agents can be administered within minutes of each other or within 1, 2, 3, 6, 9, 12, 15, 18, or 24 hours of each other or within 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14 days of each other or within 2, 3, 4, 5, 6, 7, 8, 9, or 10 weeks of each other. In some cases even longer intervals are possible. While in many cases it is desirable that the two or more agents used in a combination therapy be present in within the patient's body at the same time, this need not be so. Combination therapy can also include two or more administrations of one or more of the agents used in the combination. For example, if agent X and agent Y are used in a combination, one could administer them sequentially in any combination one or more times, e.g., in the order X-Y-X, X-X-Y, Y-X-Y, Y-Y-X, X-X-Y-Y, etc. Combination therapy can also include the administration of two or more agents via different routes or locations. For example, (a) one agent is administered orally and another agent is administered intravenously or (b) one agent is administered orally and another is administered locally into the site of injury (e.g. an artery). In each case, the agents can either simultaneously or sequentially. Approximated dosages for some of the combination therapy agents described herein are found in the “BNF Recommended Dose” column of tables on pages 11-17 of WOO1/76632 (the data in the tables being attributed to the March 2000 British National Formulary) and can also be found in other standard formularies and other drug prescribing directories. For some drugs, the customary prescribed dose for an indication will vary somewhat from country to country.

Lipid modulating agents are dyslipidemic agents which function as high density lipoprotein (HDL), including synthetic HDL which contains lipid such as phosphotidyl choline, phosphatidyl serine, phosphatidyl ethanolamine, and other phospholipids in combination with HDL associated proteins such as ApoA-I or variants thereof including ApoAI-Milano (R173C) and biologically active peptides derived therefrom, the ApoA-I Paris variant (R151C), the reverse lipid transport (RLT) peptides, enzymes associated with HDL such as paraoxonase, and apo E, alone or formulated in combination with liposomes or emulsions (an example of a liposomal formulation is found in WO95/23592), see, for example, US20030109442 and US20050096307. HDL associated proteins include sequences present in HDL associated proteins that associate with HDL and synthetic peptides having equivalent binding or functional characteristics. HDL-associated proteins further include apolipoproteins such as Apo E, proApoA-I, ApoA-IParis, ApoA-II, proApoA-π, ApoA-IV, ApoC-I, ApoC-II, ApoC-π, including variants thereof which have been modified to include one or more sulfhydral groups, as described by Bielicki and Oda, Biochemistry 41:2089-2096 (2002). HDL-associated proteins further include paraoxonase, cholesteryl ester transfer protein, Lecithin Cholesterol Acyltransferase (LCAT), phospholipid transfer protein, including combinations thereof complexed with and without lipid. HDL-associated proteins can be used alone, in combination, complexed to one or more lipids alone or in combination complexed to one or more lipids. Non limiting examples include complexes comprising ApoA-I and lipid, complexes comprising paraoxanase and lipid, and complexes comprising ApoA-I, paraoxonase and lipid. HDL-associated proteins and lipids can be mixed in an aqueous solution in appropriate ratios complexed by methods known in the art and including freeze-drying, detergent solubilization followed by dialysis, microfluidization, sonication, and homogenization. Complex efficiency can be optimized, for example, by varying pressure, ultrasonic frequency, or detergent concentration. An example of a detergent commonly used to prepared HDL-associated protein-lipid complexes is sodium cholate. In some cases it is desirable to mix the lipid and the HDL-associated protein prior to administration. Lipids may be in solution or in the form of liposomes or emulsions formed using standard techniques such as sonication or extrusion. Sonication is generally performed with a tip sonifier, such as a Branson tip sonifier, in an ice bath. Typically, the suspension is subjected to several sonication cycles. Extrusion may be carried out by biomembrane extruders, such as the Lipex Biomembrane Extruder. Defined pore size in the extrusion filters may generate unilamellar liposomal vesicles of specific sizes. The liposomes may also be formed by extrusion through an asymmetric ceramic filter, such as a Ceraflow Microfilter, commercially available from the Norton Company, Worcester Mass. or through a polycarbonate filter or other types of polymerized materials (i.e. plastics) commonly known. In some cases, the dyslipidemic agent comprises an HDL-associated protein with little or no lipid. Non limiting examples of lipids include phospholipids (such as soy phosphatidylcholine, egg phosphatidylcholine, soy phosphatidylglycerol, egg phosphatidylglycerol, palmitoyl-oleoyl-Phosphatidylcholine distearoylphosphatidylcholine, distearoylphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, sphingomyelin, phosphatidylserine, phosphatidic acid, N-(2,3-di(9-(Z)-octadecenyloxy))-Prop-1-yl-N,N,N-trimethylammonium chloride, phosphatidylethanolamine, lysolecithin, lysophosphatidyl-ethanolamine, phosphatidylinositol, cephalin, cardiolipin, cerebrosides, dicetylphosphate, dioleoylphosphatidylcholine, dipalmitoylphosphatidylcholine, dipalmitoylphosphatidylglycerol, dioleoylphosphatidylglycerol, stearoyl-palmitoyl-Phosphatidylcholine, di-Palmitoyl-Phosphatidylethanolamine, distearoyl-Phosphatidylethanolamine, dimyrstoyl-Phosphatidylserine, and dioleyl-Phosphatidylcholine) and non-Phosphorus containing lipids (such as stearylamine, docecylamine, acetyl palmitate, and fatty acid amides). Additional lipids suitable for use are well known to persons of skill in the art and are cited in a variety of well known sources, e.g., McCutcheon's Detergents and Emulsifiers and McCutcheon's Functional Materials, Allured Publishing Co., Ridgewood, N.J. Generally, it is desirable that the lipids are liquid-crystalline at 37° C., 35° C., or 32° C. The concentration of the lipid in the formulation may vary. Persons of skill may vary these concentrations to optimize treatment with different lipid components or of particular patients. ApoAl is combined with lipid in a ratio by weight of between 1:0.5 to 1:3. In certain embodiments, more lipid being preferred for clearance of cholesterol. The ratio may be around 1:1 is to produce the most homogenous population and for purposes of producing stable and reproducible batches. In certain embodiments, the lipid modulating agent is ETC-216, which is a synthetic HDL complex composed of 14 mg/mL of recombinant apolipoprotein A-I Milano and 13 mg/mL of 1-Palmitoyl-2-oleoyl phosphatidyl choline (POPC) complex in sucrose-mannitol-Phosphate buffer solution (sterile 6.4% sucrose, 0.8% mannitol in 6 mmol/L phosphate buffer, pH 7.4) (Esperion Therapeutics, Inc.), as a ready to inject solution or saline.

Hemorrheologic agent as used herein describes those compounds which improve the flow properties of blood by decreasing its viscosity. A suitable hemorrheologic agent of the present invention is pentoxifylline (1H-Purine-2,6-dione, 3,7-dihydro-3,7-dimethyl-1-(5-oxohexyl)-(9Cl) (CA INDEX NAME) Theobromine, 1-(5-oxohexyl)-, CAS Registry Number 6493-05-6 e.g., Trentali® (Aventis)).

Pentoxifylline and its metabolites (which can be useful in the present invention) improve the flow properties of blood by decreasing its viscosity. In patients with chronic peripheral arterial disease, this increases blood flow to the affected microcirculation and enhances tissue oxygenation. The precise mode of action of pentoxifylline and the sequence of events leading to clinical improvement are still to be defined. Pentoxifylline administration has been shown to produce dose-related hemorrheologic effects, lowering blood viscosity, and improving erythrocyte flexibility. Leukocyte properties of hemorrheologic importance have been modified in animal and in vitro human studies. Pentoxifylline has been shown to increase leukocyte deformability and to inhibit neutrophil adhesion and activation. Tissue oxygen levels have been shown to be significantly increased by therapeutic doses of pentoxifylline in patients with peripheral arterial disease.

Lipoprotein-associated coagulation inhibitor (LACI) is a serum glycoprotein with a molecular weight of 38,000 Kd useful as a blood modifier of the present invention 1t is also known as tissue factor inhibitor because it is a natural inhibitor of thromboplastin (tissue factor) induced coagulation (U.S. Pat. No. 5,110,730 and U.S. Pat. No. 5,106,833 described tissue factor and are hereby incorporated by reference their entireties). LACI is a protease inhibitor and has 3 Kunitz domains, two of which are known to interact with factors VII and X a respectively, while the function of the third domain is unknown. Many of the structural features of LACI can be deduced because of its homology with other well studies proteases. LACI is not an enzyme, so it probably inhibits its protease target in a stoichiometric manner; namely, one of the domains of LACI inhibits one protease molecule (see U.S. Pat. No. 606,374).

It can be useful to administer a compound described herein together with a sterol or stanol composition. Sterols and stands include but are not limited to those described herein. Plant sterols and stanols (e.g., beta-sitosterol) have been used as dietary supplements to reduce serum cholesterol levels. Plant sterol can be esterified to create stanol esters (also referred to as stanols), which are also used as food additives. Sterols are typically derived from agricultural sources, such as corn, soy-based, and pine tree mixtures. Stanols can be created through the reaction of the sterol with the suitable acid. Suitable acids include saturated, unsaturated, and polyunsaturated acids. Suitable acids include but are not limited to, stearic, butyric, lauric, palmitic, oleic, linoleic, linolenic, docohexanoic acid, and the like. Suitable methods for preparing these esters are well known in the art, see, e.g., U.S. Pat. No. 5,502,045 and U.S. Pat. No. 5,723,747. Sterols and sterol esters can be formulated a self-dispersing particles that are small enough to be effective when administered by ingestion (see, e.g., U.S. Pat. No. 6,387,411, U.S. Pat. No. 6,376,481 and US20040033202). Sterols and/or sterol esters in particle form can be combined with a compound described herein to create useful pharmaceutical compositions which can also include other agents such as 1, 2, 3, or more of an HMG-CoA reductase inhibitor (e.g. a statin such as atorvastatin, atorvastatin calcium, rosuvastatin, rosuvastatin calcium, simvastatin), a fibrate (e.g. fenofibrate(Tricor®)), niacin (including derivatives and extended release formulations (e.g. Niaspan®) thereof), a glitazone (e.g. rosiglitazone maleate (Avandia®), piogilitazone hydrochloride(Actos®)), a calcium channel blocker (e.g. amlodipine besylate (Norvasc®)), an angiotensin II receptor antagonist (e.g. valsartan (Diovan®, Diovan HCT® (valsartan and hydrochlorothiazide))), a biguanide (e.g. metformin (Glucophage®)), a sulfonylurea (e.g. glipizide (Glucotrol®, Glucotrol XL®), glyburide (Micronase®, Glynase Prestab®, Diabeta®), and Glucovance® (glyburide and metformin). The pharmaceutical composition can include additional ingredients such as stabilizers or bulking agents. The sterol particles in the composition can have any suitable size, e.g., 10-150 microns in diameter. However, to improve absorption in the body it can be desirable to use much smaller particles, e.g., less than 2000 nm in diameter as explained in US20040033202. Thus, pharmaceutical compositions that include a compound described herein can include sterol nanoparticles, such as sitosterol and/or phytosterol nanoparticles, which have an effective average particle size of less than about 2000 nm, less than about 1900 nm, less than about 1800 nm, less than about 1700 nm, less than about 1600 nm, less than about 1500 nm, less than about 1400 nm, less than about 1300 nm, less than about 1200 nm, less than about 1100 nm, less than about 1000 nm, less than about 900 nm, less than about 800 nm, less than about 700 nm, less than about 600 nm, less than about 500 nm, less than about 400 nm, less than about 300 nm, less than about 250 nm, less than about 200 nm, less than about 150 nm, less than about 100 nm, less than about 75 nm, or less than about 50 nm, as measured by light-scattering methods, microscopy, or other appropriate methods. The particles can be created by methods which include: milling, precipitation and homogenization. For example, homogenization methods are described in U.S. Pat. No. 5,510,118. The method includes dispersing sterol particles in a liquid dispersion medium in which the sterol is poorly soluble, followed by subjecting the dispersion to homogenization to reduce the particle size of the sterol to the desired effective average particle size. The sterol particles are preferably reduced in size in the presence of at least one surface stabilizer. Alternatively, the sterol particles can be contacted with one or more surface stabilizers either before or after attrition. Other compounds, such as a diluent, can be added to the sterol/surface stabilizer composition before, during, or after the size reduction process. Dispersions can be manufactured continuously or in a batch mode. Surface stabilizers can be used in the formulations. Suitable surface stabilizers include: cetyl pyridinium chloride, gelatin, casein, phospha-tides, dextran, glycerol, gum acacia, cholesterol, tragacanth, stearic acid, benzalkonium chloride, calcium stearate, glycerol monostearate, cetostearyl alcohol, cetomacrogol emulsifying wax, sorbitan esters, polyoxyethylene alkyl ethers, polyoxyethylene castor oil derivatives, polyoxy-ethylene sorbitan fatty acid esters, polyethylene glycols, dodecyl trimethyl ammonium bromide, polyoxyethylene stearates, colloidal silicon dioxide, phosphates, sodium dodecylsulfate, carboxy-methylcellulose calcium, hydroxypropyl celluloses, hypromellose, carboxymethylcellulose sodium, methylcellulose, hydroxyethylcellulose, hypromellose phthalate, noncrystalline cellulose, magnesium aluminum silicate, triethanolamine, polyvinyl alcohol, polyvinylpyrrolidone, 4-(1,1,3,3-tetramethylbutyl)-Phenol polymer with ethylene oxide and formaldehyde, poloxamers; poloxamines, a charged phospholipid, dioctylsulfosuccinate, dialkylesters of sodium sulfosuc-cinic acid, sodium lauryl sulfate, alkyl aryl polyether sulfonates, mixtures of sucrose stearate and sucrose distearate, p-isononylphenoxypoly-(glycidol), decanoyl-N-methylglucamide; n-decyl β-D-glucopyranoside; n-decyl β-D-maltopyranoside; n-dodecyl β-D-glucopyranoside; n-dodecyl SD-maltoside; heptanoyl-N-methylglucamide; n-heptyl-βD-glucop-yranoside; n-heptyl β-D-thioglucoside; n-hexyl β-D-glucopyranoside; nonanoyl-N-methylglucamide; n-noyl β-D-glucopy-ranoside; octanoyl-N-methylglucamide; n-octyl-β-D-glucopyranoside; ocτyl β-D-thioglucopyranoside; lysozyme, PEG-Phospholipid, PEG-cholesterol, PEG-cholesterol derivative, PEG-vitamin A, PEG-vitamin E, and random copolymers of vinyl acetate and vinyl pyrrolidone.

It can be useful to administer a compound described herein together with a polycosanol composition. Polycosanol compositions are complex mixtures of concentrated n-alkyl alcohols derived from, e.g., sugar cane and the wax of honey bees. Polycosanol compositions are reported to produce cholesterol lowering effects within the first 6-8 weeks of use. According to US20030232796, at a daily polycosanol dosage of 10 mg taken at night, LDL cholesterol levels typically drop by 20-25% within the first six months of use. At a dosage of 20 mg, LDL levels typically drop by 25-30%. HDL levels typically increase by 15-25% only after two months of use. The combined LDL reduction and HDL increase will produce a significant and dramatic improvement in the LDL to HDL ratio. Polycosanol can include fatty acid components including: 1-Octacosanol, 1-Triacontanol, 1-Tetracosanol, and 1-Hexacosanol. Typical usage levels range from 500-10,000 micrograms per serving/dose. Typical commercially available commercial compositions are 90% minimum fatty alcohols of (a) 1-Tetracosanol: 0-10%; (b) 1-Hexacosanol: 2-15%; (c) 1-Heptacosanol: 0-0.5%; (d) 1-Octacosanol: 55-70%; (e) 1-Nonacosanol: 0-10%; (f) 1-Triacontanol: 5-20%; (g) 1-Dotriacontanol: 0.1-10%; and (h) 1-Tetratriacontanol: 0.1-10%. Polycosanol compositions can be formulated as described above for stands both with respect to particle size and overall formulation. In addition to the compounds described herein, the formulation can include other agents such as 1, 2, 3, or more of an HMG-CoA reductase inhibitor (e.g. a statin such as atorvastatin, atorvastatin calcium, rosuvastatin, rosuvastatin calcium, simvastatin), a fibrate (e.g. fenofibrate(Tricor®)), niacin (including derivatives and extended release formulations (e.g. Niaspan®) thereof), a glitazone (e.g. rosi-glitazone maleate (Avandia®), piogilitazone hydrochloride(Actos®)), a calcium channel blocker (e.g. amlodipine besylate (Norvasc®)), an angiotensin II receptor antagonist (e.g. valsartan (Diovan®, Diovan HCT® (valsartan and hydrochlorothiazide))), a biguanide (e.g. metformin (Glucophage®)), a sulfonylurea (e.g. glipizide (Glucotrol®, Glucotrol XL®), glyburide (Micronase®, Glynase Prestab®, Diabeta®), and Glucovance® (glyburide and metformin).

Combining two or more active ingredients in single dosage form results in the possibility of chemical interactions between the active drug substances. For example, acidic and basic active ingredients can react with each other and acidic active ingredients can facilitate the degradation of acid labile substances. Thus, in certain dosage forms, acidic and basic substances can be physically separated as two distinct or isolated layers in a compressed tablet, or in the core and shell of a press-coated tablet. Additional agents that are compatible with acidic as well as basic substances, have the flexibility of being placed in either layer. In certain multiple layer compositions at least one active ingredient can be enteric-coated. In certain embodiments thereof at least one active ingredient can be presented in a controlled release form. In certain embodiments where a combination of three or more active substances are used, they can be presented as physically isolated segments of a compressed mutlilayer tablet, which can be optionally film coated.

The therapeutic combinations described herein can be formulated as a tablet or capsule comprising a plurality of beads, granules, or pellets. AU active ingredients including the vitamins of the combination are formulated into granules or beads or pellets that are further coated with a protective coat, an enteric coat, or a film coat to avoid the possible chemical interactions. Granulation and coating of granules or beads is done using techniques well known to a person skilled in the art. At least one active ingredient can present in a controlled release form. Finally these coated granules or beads are filled into hard gelatin capsules or compressed to form tablets.

The therapeutic combinations described herein can be formulated as a capsule comprising microtablets or minitablets of all active ingredients. Microtablets of the individual agents can be prepared using well known pharmaceutical procedures of tablet making like direct compression, dry granulation or wet granulation. Individual microtablets can be filled into hard gelatin capsules. A final dosage form may comprise one or more microtablets of each individual component. The microtablets may be film coated or enteric coated.

The therapeutic combinations described herein can be formulated as a capsule comprising one or more microtablets and powder, or one or more microtablets and granules or beads. In order to avoid interactions between drugs, some active ingredients of a said combination can be formulated as microtablets and the others filled into capsules as a powder, granules, or beads. The microtablets may be film coated or enteric coated. At least one active ingredient can be presented in controlled release form.

The therapeutic combinations described herein can be formulated wherein the active ingredients are distributed in the inner and outer phase of tablets. In an attempt to divide chemically incompatible components of proposed combination, few interacting components are converted in granules or beads using well known pharmaceutical procedures in prior art. The prepared granules or beads (inner phase) are then mixed with outer phase comprising the remaining active ingredients and at least one pharmaceutically acceptable excipient. The mixture thus comprising inner and outer phase is compressed into tablets or molded into tablets. The granules or beads can be controlled release or immediate release beads or granules, and can further be coated using an enteric polymer in an aqueous or non-aqueous system, using methods and materials that are known in the art.

The therapeutic combinations described herein can be formulated as single dosage unit comprising suitable buffering agent. All powdered ingredients of said combination are mixed and a suitable quantity of one or more buffering agents is added to the blend to minimize possible interactions.

The agents described herein, alone or in combination, can be combined with any pharmaceutically acceptable carrier or medium. Thus, they can be combined with materials that do not produce an adverse, allergic or otherwise unwanted reaction when administered to a patient. The carriers or mediums used can include solvents, dispersants, coatings, absorption promoting agents, controlled release agents, and one or more inert excipients (which include starches, polyols, granulating agents, microcrystalline cellulose, diluents, lubricants, binders, disintegrating agents, and the like), etc. If desired, tablet dosages of the disclosed compositions may be coated by standard aqueous or nonaqueous techniques.

The agents can be a free acid or base, or a pharmacologically acceptable salt thereof. Solids can be dissolved or dispersed immediately prior to administration or earlier. In some circumstances the preparations include a preservative to prevent the growth of microorgan-isms. The pharmaceutical forms suitable for injection can include sterile aqueous or organic solutions or dispersions which include, e.g., water, an alcohol, an organic solvent, an oil or other solvent or dispersant (e.g., glycerol, propylene glycol, polyethylene glycol, and vegetable oils). The formulations may contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives.

Orally administered formulations such as tablets may optionally be coated or scored and may be formulated so as to provide sustained, delayed or controlled release of the active ingredient therein. The agents of the invention can also be administered by captisol delivery technology, rectal suppository or parenterally.

The agents described herein can be either in their free form or as a salt can be combined with a polymer such as polylactic-glycoloic acid (PLGA), poly-(T)-lactic-glycolic-tartaric acid (P(I)LGT) (WOO1/12233), polyglycolic acid (U.S. Pat. No. 3,773,919), polylactic acid (U.S. Pat. No. 4,767,628), poly(M-caprolactone) and poly(alkylene oxide) (US20030068384) to create a sustained release formulation. Such formulations can be used within implants that release a compound of the invention and/or another agent over a period of a few days, a few weeks or several months depending on the polymer, the particle size of the polymer, and the size of the implant (see, e.g., U.S. Pat. No. 6,620,422 and WO05/0 11769). Other sustained release formulations are described in EP0467389, WO93/241150, U.S. Pat. No. 5,612,052, WO97/40085, WO03/075887, WO01/01964, U.S. Pat.

Controlled Release Formulations

In general, one can provide for controlled release of the agents described herein through the use of a wide variety of polymeric carriers and controlled release systems including erodible and non-erodible matrices, osmotic control devices, various reservoir devices, enteric coatings and multiparticulate control devices.

Matrix devices are a common device for controlling the release of various agents. In such devices, the agents described herein are generally present as a dispersion within the polymer matrix, and are typically formed by the compression of a polymer/drug mixture or by dissolution or melting. The dosage release properties of these devices may be dependent upon the solubility of the agent in the polymer matrix or, in the case of porous matrices, the solubility in the sink solution within the pore network, and the tortuosity of the network. In one instance, when utilizing an erodible polymeric matrix, the matrix imbibes water and forms an aqueous-swollen gel that entraps the agent. The matrix then gradually erodes, swells, disintegrates or dissolves in the GI tract, thereby controlling release of one or more of the agents described herein. In non-erodible devices, the agent is released by diffusion through an inert matrix.

Agents described herein can be incorporated into an erodible or non-erodible polymeric matrix controlled release device. By an erodible matrix is meant aqueous-erodible or water-swellable or aqueous-SOluble in the sense of being either erodible or swellable or dissolvable in pure water or requiring the presence of an acid or base to ionize the polymeric matrix sufficiently to cause erosion or dissolution. When contacted with the aqueous environment of use, the erodible polymeric matrix imbibes water and forms an aqueous-swollen gel or matrix that entraps the agent described herein. The aqueous-swollen matrix gradually erodes, swells, disintegrates or dissolves in the environment of use, thereby controlling the release of a compound described herein to the environment of use. Nonlimiting examples of such devices are disclosed in U.S. patent application Ser. No. 09/495,059 filed Jan. 31, 2000.

The erodible polymeric matrix into which an agent described herein can be incorporated may generally be described as a set of excipients that are mixed with the agent following its formation that, when contacted with the aqueous environment of use imbibes water and forms a water-swollen gel or matrix that entraps the drug form. Drug release may occur by a variety of mechanisms, for example, the matrix may disintegrate or dissolve from around particles or granules of the agent or the agent may dissolve in the imbibed aqueous solution and diffuse from the tablet, beads or granules of the device. One ingredient of this water-swollen matrix is the water-swellable, erodible, or soluble polymer, which may generally be described as an osmopolymer, hydrogel or water-swellable polymer. Such polymers may be linear, branched, or crosslinked. The polymers may be homopolymers or copolymers. In certain embodiments, they maybe synthetic polymers derived from vinyl, acrylate, methacrylate, urethane, ester and oxide monomers. In other embodiments, they can be derivatives of naturally occurring polymers such as polysaccharides (e.g. chitin, chitosan, dextran and pullulan; gum agar, gum arabic, gum karaya, locust bean gum, gum tragacanth, carrageenans, gum ghatti, guar gum, xanthan gum and scleroglucan), starches (e.g. dextrin and maltodextrin), hydrophilic colloids (e.g. pectin), phosphatides (e.g. lecithin), alginates (e.g. ammonium alginate, sodium, potassium or calcium alginate, propylene glycol alginate), gelatin, collagen, and cellulosics. Cellulosics are cellulose polymer that has been modified by reaction of at least a portion of the hydroxyl groups on the saccharide repeat units with a compound to form an ester-linked or an ether-linked substituent. For example, the cellulosic ethyl cellulose has an ether linked ethyl substituent attached to the saccharide repeat unit, while the cellulosic cellulose acetate has an ester linked acetate substituent. In certain embodiments, the cellulosics for the erodible matrix comprises aqueous-SOluble and aqueous-erodible cellulosics can include, for example, ethyl cellulose (EC), methylethyl cellulose (MEC), carboxymethyl cellulose (CMC), CMEC, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), cellulose acetate (CA), cellulose propionate (CP), cellulose butyrate (CB), cellulose acetate butyrate (CAB), CAP, CAT, hydroxypropyl methyl cellulose (HPMC), HPMCP, HPMCAS, hydroxypropyl methyl cellulose acetate trimellitate (HPMCAT), and ethylhydroxy ethylcellulose (EHEC). In certain embodiments, the cellulosics comprises various grades of low viscosity (MW less than or equal to 50,000 daltons, for example, the Dow Methocel™ series E5, E15LV, E50LV and KlOOLY) and high viscosity (MW greater than 50,000 daltons, for example, E4MCR, ElOMCR, K4M, K15M and KlOOM and the Methocel™ K series) HPMC. Other commercially available types of HPMC include the Shin Etsu Metolose 90SH series.

The choice of matrix material can have a large effect on the maximum drug concentration attained by the device as well as the maintenance of a high drug concentration. The matrix material can be a concentration-enhancing polymer, for example, as described in WO05/01 1634.

Other materials useful as the erodible matrix material include, but are not limited to, pullulan, polyvinyl pyrrolidone, polyvinyl alcohol, polyvinyl acetate, glycerol fatty acid esters, polyacrylamide, polyacrylic acid, copolymers of ethacrylic acid or methacrylic acid (EUDRAGITO, Rohm America, Inc., Piscataway, N.J.) and other acrylic acid derivatives such as homopolymers and copolymers of butylmethacrylate, methylmethacrylate, ethylmethacrylate, ethylacrylate, (2-dimethylaminoethyl)methacrylate, and (trimethylaminoethyl)methacrylate chloride.

The erodible matrix polymer may contain a wide variety of the same types of additives and excipients known in the pharmaceutical arts, including osmopolymers, osmagens, solubility-enhancing or -retarding agents and excipients that promote stability or processing of the device.

Alternatively, the agents of the present invention may be administered by or incorporated into a non-erodible matrix device. In such devices, an agent described herein is distributed in an inert matrix. The agent is released by diffusion through the inert matrix. Examples of materials suitable for the inert matrix include insoluble plastics (e.g. methyl acrylate-methyl methacrylate copolymers, polyvinyl chloride, polyethylene), hydrophilic polymers (e.g. ethyl cellulose, cellulose acetate, crosslinked polyvinylpyrrolidone (also known as crospovidone)), and fatty compounds (e.g. carnauba wax, microcrystalline wax, and triglycerides). Such devices are described further in Remington: The Science and Practice of Pharmacy, 20th edition (2000).

Matrix controlled release devices may be prepared by blending an agent described herein and other excipients together, and then forming the blend into a tablet, caplet, pill, or other device formed by compressive forces. Such compressed devices may be formed using any of a wide variety of presses used in the fabrication of pharmaceutical devices. Examples include single-Punch presses, rotary tablet presses, and multilayer rotary tablet presses, all well known in the art. See for example, Remington: The Science and Practice of Pharmacy, 20th Edition, 2000. The compressed device may be of any shape, including round, oval, oblong, cylindrical, or triangular. The upper and lower surfaces of the compressed device may be flat, round, concave, or convex.

In certain embodiments, when formed by compression, the device has a strength of at least 5 Kiloponds (Kp)/cm²(for example, at least 7 Kp/cm²). Strength is the fracture force, also known as the tablet hardness required to fracture a tablet formed from the materials, divided by the maximum cross-sectional area of the tablet normal to that force. The fracture force may be measured using a Schleuniger Tablet Hardness Tester, Model 6D. The compression force required to achieve this strength will depend on the size of the tablet, but generally will be greater than about 5 kP/cm². Friability is a well-know measure of a device's resistance to surface abrasion that measures weight loss in percentage after subjecting the device to a standardized agitation procedure. Friability values of from 0.8 to 1.0% are regarded as constituting the upper limit of acceptability. Devices having a strength of greater than 5 kP/cm²generally are very robust, having a friability of less than 0.5%. Other methods for forming matrix controlled-release devices are well known in the pharmaceutical arts. See for example, Remington: The Science and Practice of Pharmacy, 20th Edition, 2000.

As noted above, the agents described herein may also be incorporated into an osmotic control device. Such devices generally include a core containing one or more agents as described herein and a water permeable, non-dissolving and non-eroding coating surrounding the core which controls the influx of water into the core from an aqueous environment of use so as to cause drug release by extrusion of some or all of the core to the environment of use. In certain embodiments, the coating is polymeric, aqueous-Permeable, and has at least one delivery port. The core of the osmotic device optionally includes an osmotic agent which acts to imbibe water from the surrounding environment via such a semi-Permeable membrane. The osmotic agent contained in the core of this device may be an aqueous-swellable hydrophilic polymer or it may be an osmogen, also known as an osmagent. Pressure is generated within the device which forces the agent(s) out of the device via an orifice (of a size designed to minimize solute diffusion while preventing the build-up of a hydrostatic pressure head). Nonlimiting examples of osmotic control devices are disclosed in U.S. patent application Ser. No. 09/495,061.

Osmotic agents create a driving force for transport of water from the environment of use into the core of the device. Osmotic agents include but are not limited to water-swellable hydrophilic polymers, and osmogens (or osmagens). Thus, the core may include water-swellable hydrophilic polymers, both ionic and nonionic, often referred to as osmopolymers and hydrogels. The amount of water-swellable hydrophilic polymers present in the core may range from about 5 to about 80 wt % (including for example, 10 to 50 wt %). Nonlimiting examples of core materials include hydrophilic vinyl and acrylic polymers, polysaccharides such as calcium alginate, polyethylene oxide (PEO), polyethylene glycol (PEG), polypropylene glycol (PPG), poly(2-hydroxyethyl methacrylate), poly(acrylic) acid, poly(methacrylic) acid, polyvinylpyrrolidone (PVP) and crosslinked PVP, polyvinyl alcohol (PVA), PVA/PVP copolymers and PVA/PVP copolymers with hydrophobic monomers such as methyl methacrylate, vinyl acetate, and the like, hydrophilic polyurethanes containing large PEO blocks, sodium croscarmellose, carrageenan, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) and carboxyethyl cellulose (CEC), sodium alginate, polycarbophil, gelatin, xanthan gum, and sodium starch glycolat. Other materials include hydrogels comprising interpenetrating networks of polymers that may be formed by addition or by condensation polymerization, the components of which may comprise hydrophilic and hydrophobic monomers such as those just mentioned. Water-swellable hydrophilic polymers include but are not limited to PEO, PEG, PVP, sodium croscarmellose, HPMC, sodium starch glycolate, polyacrylic acid and crosslinked versions or mixtures thereof.

The core may also include an osmogen (or osmagent). The amount of osmogen present in the core may range from about 2 to about 70 wt % (including, for example, from 10 to 50 wt %). Typical classes of suitable osmogens are water-SOluble organic acids, salts and sugars that are capable of imbibing water to thereby effect an osmotic pressure gradient across the barrier of the surrounding coating. Typical useful osmogens include but are not limited to magnesium sulfate, magnesium chloride, calcium chloride, sodium chloride, lithium chloride, potassium sulfate, sodium carbonate, sodium sulfite, lithium sulfate, potassium chloride, sodium sulfate, mannitol, xylitol, urea, sorbitol, inositol, raffinose, sucrose, glucose, fructose, lactose, citric acid, succinic acid, tartaric acid, and mixtures thereof. In certain embodiments, the osmogen is glucose, lactose, sucrose, mannitol, xylitol, sodium chloride, including combinations thereof.

The core may include a wide variety of additives and excipients that enhance the performance of the dosage form or that promote stability, tableting or processing. Such additives and excipients include tableting aids, surfactants, water-soluble polymers, pH modifiers, fillers, binders, pigments, disintegrants, antioxidants, lubricants and flavorants. Nonlimiting examples of additives and excipients include but are not limited to those described elsewhere herein as well as microcrystalline cellulose, metallic salts of acids (e.g. aluminum stearate, calcium stearate, magnesium stearate, sodium stearate, zinc stearate), pH control agents (e.g. buffers, organic acids, organic acid salts, organic and inorganic bases), fatty acids, hydrocarbons and fatty alcohols (e.g. stearic acid, palmitic acid, liquid paraffin, stearyl alcohol, and palmitol), fatty acid esters (e.g. glyceryl(mono- and di-) stearates, triglycerides, glyceryl(palmiticstearic) ester, sorbitan esters (e.g. sorbitan monostearate, saccharose monostearate, saccharose monopalmitate, sodium stearyl fumarate), polyoxyethylene sorbitan esters), surfactants (e.g. alkyl sulfates (e.g. sodium lauryl sulfate, magnesium lauryl sulfate), polymers (e.g. polyethylene glycols, polyoxyethylene glycols, polyoxyethylene, polyoxypropylene ethers, including copolymers thereof), polytetrafluoroethylene), and inorganic materials (e.g. talc, calcium phosphate), cyclodextrins, sugars (e.g. lactose, xylitol), sodium starch glycolate). Nonlimiting examples of disintegrants are sodium starch glycolate (e.g., Explotab™ CLV, (microcrystalline cellulose (e.g., Avicel™), microcrystalline silicified cellulose (e.g., ProSolv™), croscarmellose sodium (e.g., Ac-Di-SOl™). When the agent described herein is a solid amorphous dispersion formed by a solvent process, such additives may be added directly to the spray-drying solution when forming an agent described herein/concentration-enhancing polymer dispersion such that the additive is dissolved or suspended in the solution as a slurry, Alternatively, such additives may be added following the spray-drying process to aid in forming the final controlled release device.

A nonlimiting example of an osmotic device consists of one or more drug layers containing an agent described herein, such as a solid amorphous drug/polymer dispersion, and a sweller layer that comprises a water-swellable polymer, with a coating surrounding the drug layer and sweller layer. Each layer may contain other excipients such as tableting aids, osmagents, surfactants, water-SOluble polymers and water-swellable polymers.

Such osmotic delivery devices may be fabricated in various geometries including bilayer (wherein the core comprises a drug layer and a sweller layer adjacent to each other), trilayer (wherein the core comprises a sweller layer sandwiched between two drug layers) and concentric (wherein the core comprises a central sweller agent surrounded by the drug layer). The coating of such a tablet comprises a membrane permeable to water but substantially impermeable to drug and excipients contained within. The coating contains one or more exit passageways or ports in communication with the drug-containing layer(s) for delivering the drug agent. The drug-containing layer(s) of the core contains the drug agent (including optional osmagents and hydrophilic water-SOluble polymers), while the sweller layer consists of an expandable hydrogel, with or without additional osmotic agents.

When placed in an aqueous medium, the tablet imbibes water through the membrane, causing the agent to form a dispensable aqueous agent, and causing the hydrogel layer to expand and push against the drug-containing agent, forcing the agent out of the exit passageway. The agent can swell, aiding in forcing the drug out of the passageway. Drug can be delivered from this type of delivery system either dissolved or dispersed in the agent that is expelled from the exit passageway.

The rate of drug delivery is controlled by such factors as the permeability and thickness of the coating, the osmotic pressure of the drug-containing layer, the degree of hydrophilicity of the hydrogel layer, and the surface area of the device. Those skilled in the art will appreciate that increasing the thickness of the coating will reduce the release rate, while any of the following will increase the release rate: increasing the permeability of the coating; increasing the hydrophilicity of the hydrogel layer; increasing the osmotic pressure of the drug-containing layer; or increasing the device's surface area.

Other materials useful in forming the drug-containing agent, in addition to the agent described herein itself, include HPMC, PEO and PVP and other pharmaceutically acceptable carriers. In addition, osmagents such as sugars or salts, including but not limited to sucrose, lactose, xylitol, mannitol, or sodium chloride, may be added. Materials which are useful for forming the hydrogel layer include sodium CMC, PEO (e.g. polymers having an average molecular weight from about 5,000,000 to about 7,500,000 daltons), poly (acrylic acid), sodium (polyacrylate), sodium croscarmellose, sodium starch glycolat, PVP, crosslinked PVP, and other high molecular weight hydrophilic materials.

In the case of a bilayer geometry, the delivery port(s) or exit passageway(s) may be located on the side of the tablet containing the drug agent or may be on both sides of the tablet or even on the edge of the tablet so as to connect both the drug layer and the sweller layer with the exterior of the device. The exit passageway(s) may be produced by mechanical means or by laser drilling, or by creating a difficult-to-coat region on the tablet by use of special tooling during tablet compression or by other means.

The osmotic device can also be made with a homogeneous core surrounded by a semipermeable membrane coating, as in U.S. Pat. No. 3,845,770. The agent described herein can be incorporated into a tablet core and a semipermeable membrane coating can be applied via conventional tablet-coating techniques such as using a pan coater. A drug delivery passageway can then be formed in this coating by drilling a hole in the coating, either by use of a laser or mechanical means. Alternatively, the passageway may be formed by rupturing a portion of the coating or by creating a region on the tablet that is difficult to coat, as described above. In one embodiment, an osmotic device comprises: (a) a single-layer compressed core comprising: (i) an agent described herein, (ii) a hydroxyethylcellulose, and (iii) an osmagent, wherein the hydroxyl-ethylcellulose is present in the core from about 2.0% to about 35% by weight and the osmagent is present from about 15% to about 70% by weight; (b) a water-Permeable layer surrounding the core; and (c) at least one passageway within the water-Permeable layer (b) for delivering the drug to a fluid environment surrounding the tablet. In certain embodiments, the device is shaped such that the surface area to volume ratio (of a water-swollen tablet) is greater than 0.6 mm⁻¹(including, for example, greater than 1.0 mm⁻¹). The passageway connecting the core with the fluid environment can be situated along the tablet band area. In certain embodiments, the shape is an ohlong shape where the ratio of the tablet tooling axes, i.e., the major and minor axes which define the shape of the tablet, are between 1.3 and 3 (including, for example, between 1.5 and 2.5). In one embodiment, the combination of the agent described herein and the osmagent have an average ductility from about 100 to about 200 Mpa, an average tensile strength from about 0.8 to about 2.0 Mpa, and an average brittle fracture index less than about 0.2. The single-layer core may optionally include a disintegrant, a bioavailability enhancing additive, and/or a pharmaceutically acceptable excipient, carrier or diluent. Nonlimiting examples of such devices are disclosed, for example, in U.S. provisional Patent Application Ser. No. 60/353,151.

In certain embodiments, entrainment of particles of agents described herein in the extruding fluid during operation of such osmotic device is desirable. For the particles to be well entrained, the agent drug form is dispersed in the fluid before the particles have an opportunity to settle in the tablet core. One means of accomplishing this is by adding a disintegrant that serves to break up the compressed core into its particulate components. Nonlimiting examples of standard disintegrants include materials such as sodium starch glycolate (e.g., Explotab™ CLV), microcrystalline cellulose (e.g., Avicel™), microcrystalline silicified cellulose (e.g., ProSOIv™) and croscarmellose sodium (e.g., Ac-Di-SOl™), and other disintegrants known to those skilled in the art. Depending upon the particular formulation, some disintegrants work better than others. Several disintegrants tend to form gels as they swell with water, thus hindering drug delivery from the device. Non-gelling, non-swelling disintegrants provide a more rapid dispersion of the drug particles within the core as water enters the core. In certain embodiments, non-gelling, non-swelling disintegrants are resins, for example, ion-exchange resins. In one embodiment, the resin is Amberlite™ IRP 88 (available from Rohm and Haas, Philadelphia, Pa.). When used, the disintegrant is present in amounts ranging from about 1-25% of the core agent.

Water-SOluble polymers are added to keep particles of the agent suspended inside the device before they can be delivered through the passageway(s) (e.g., an orifice). High viscosity polymers are useful in preventing settling. However, the polymer in combination with the agent is extruded through the passageway(s) under relatively low pressures. At a given extrusion pressure, the extrusion rate typically slows with increased viscosity. Certain polymers in combination with particles of the agent described herein form high viscosity solutions with water but are still capable of being extruded from the tablets with a relatively low force. In contrast, polymers having a low weight-average, molecular weight (<about 300,000) do not form sufficiently viscous solutions inside the tablet core to allow complete delivery due to particle settling. Settling of the particles is a problem when such devices are prepared with no polymer added, which leads to poor drug delivery unless the tablet is constantly agitated to keep the particles from settling inside the core. Settling is also problematic when the particles are large and/or of high density such that the rate of settling increases.

In certain embodiments, the water-SOluble polymers for such osmotic devices do not interact with the drug. In certain embodiments the water-SOluble polymer is a non-ionic polymer. A nonlimiting example of a non-ionic polymer forming solutions having a high visco-sity yet still extrudable at low pressures is Natrosol™ 250H (high molecular weight hydroxyethyl-cellulose, available from Hercules Incorporated, Aqualon Division, Wilmington, Del.; MW equal to about 1 million daltons and a degree of polymerization equal to about 3,700). Natrosol 250H™ provides effective drug delivery at concentrations as low as about 3% by weight of the core when combined with an osmagent. Natrosol 250H™ NF is a high-viscosity grade nonionic cellulose ether that is soluble in hot or cold water. The viscosity of a 1% solution of Natrosol 250H using a Brookfield LVT (30 rpm) at 25° C. is between about 1,500 and about 2,500 cps.

In certain embodiments, hydroxyethylcellulose polymers for use in these monolayer osmotic tablets have a weight-average, molecular weight from about 300,000 to about 1.5 million. The hydroxyethylcellulose polymer is typically present in the core in an amount from about 2.0% to about 35% by weight.

Another example of an osmotic device is an osmotic capsule. The capsule shell or portion of the capsule shell can be semipermeable. The capsule can be filled either by a powder or liquid consisting of an agent described herein, excipients that imbibe water to provide osmotic potential, and/or a water-swellable polymer, or optionally solubilizing excipients. The capsule core can also be made such that it has a bilayer or multilayer agent analogous to the bilayer, trilayer or concentric geometries described above.

Another class of osmotic device useful in this invention comprises coated swellable tablets, for example, as described in EP378404. Coated swellable tablets comprise a tablet core comprising an agent described herein and a swelling material, preferably a hydrophilic polymer, coated with a membrane, which contains holes, or pores through which, in the aqueous use environment, the hydrophilic polymer can extrude and carry out the agent. Alternatively, the membrane may contain polymeric or low molecular weight water-SOluble porosigens. Porosigens dissolve in the aqueous use environment, providing pores through which the hydrophilic polymer and agent may extrude. Examples of porosigens are water-SOluble polymers such as HPMC, PEG, and low molecular weight compounds such as glycerol, sucrose, glucose, and sodium chloride. In addition, pores may be formed in the coating by drilling holes in the coating using a laser or other mechanical means. In this class of osmotic devices, the membrane material may comprise any film-forming polymer, including polymers which are water permeable or impermeable, providing that the membrane deposited on the tablet core is porous or contains water-SOluble porosigens or possesses a macroscopic hole for water ingress and drug release. Embodiments of this class of sustained release devices may also be multilayered, as described, for example, in EP378404.

When an agent described herein is a liquid or oil, such as a lipid vehicle formulation, for example as described in WO05/01 1634, the osmotic controlled-release device may comprise a soft-gel or gelatin capsule formed with a composite wall and comprising the liquid formulation where the wall comprises a barrier layer formed over the external surface of the capsule, an expandable layer formed over the barrier layer, and a semipermeable layer formed over the expandable layer. A delivery port connects the liquid formulation with the aqueous use environment. Such devices are described, for example, in U.S. Pat. No. 6,419,952, U.S. Pat. No. 6,342,249, U.S. Pat. No. 5,324,280, U.S. Pat. No. 4,672,850, U.S. Pat. No. 4,627,850, U.S. Pat. No. 4,203,440, and U.S. Pat. No. 3,995,631.

The osmotic controlled release devices of the present invention can also comprise a coating. In certain embodiments, the osmotic controlled release device coating exhibits one or more of the following features: is water-Permeable, has at least one port for the delivery of drug, and is non-dissolving and non-eroding during release of the drug formulation, such that drug is substantially entirely delivered through the delivery port(s) or pores as opposed to delivery primarily via permeation through the coating material itself. Delivery ports include any passageway, opening or pore whether made mechanically, by laser drilling, by pore formation either during the coating process or in situ during use or by rupture during use. In certain embodiments, the coating is present in an amount ranging from about 5 to 30 wt % (including, for example, 10 to 20 wt %) relative to the core weight.

One form of coating is a semipermeable polymeric membrane that has the port(s) formed therein either prior to or during use. Thickness of such a polymeric membrane may vary between about 20 and 800 μm (including, for example, between about 100 to 500 μm). The diameter of the delivery port (s) may generally range in size from 0.1 to 3000 μm or greater (including, for example, from about 50 to 3000 μm in diameter). Such port(s) may be formed post-coating by mechanical or laser drilling or may be formed in situ by rupture of the coatings; such rupture may be controlled by intentionally incorporating a relatively small weak portion into the coating. Delivery ports may also be formed in situ by erosion of a plug of water-SOluble material or by rupture of a thinner portion of the coating over an indentation in the core. In addition, delivery ports may be formed during coating, as in the case of asymmetric membrane coatings of the type disclosed in U.S. Pat. No. 5,612,059 and U.S. Pat. No. 5,698,220. The delivery port may be formed in situ by rupture of the coating, for example, when a collection of beads that may be of essentially identical or of a variable agent are used. Drug is primarily released from such beads following rupture of the coating and, following rupture, such release may be gradual or relatively sudden. When the collection of beads has a variable agent, the agent may be chosen such that the beads rupture at various times following administration, resulting in the overall release of drug being sustained for a desired duration.

Coatings may be dense, microporous or asymmetric, having a dense region supported by a thick porous region such as those disclosed in U.S. Pat. No. 5,612,059 and U.S. Pat. No. 5,698,220. When the coating is dense the coating can be composed of a water-Permeable material. When the coating is porous, it may be composed of either a water-Permeable or a water-impermeable material. When the coating is composed of a porous water-impermeable material, water permeates through the pores of the coating as either a liquid or a vapor. Nonlimiting examples of osmotic devices that utilize dense coatings include U.S. Pat. No. 3,995,631 and U.S. Pat. No. 3,845,770. Such dense coatings are permeable to the external fluid such as water and may be composed of any of the materials mentioned in these patents as well as other water-Permeable polymers known in the art.

The membranes may also be porous as disclosed, for example, in U.S. Pat. No. 5,654,005 and U.S. Pat. No. 5,458,887 or even be formed from water-resistant polymers. U.S. Pat. No. 5,120,548 describes another suitable process for forming coatings from a mixture of a water-insoluble polymer and a leachable water-SOluble additive. The porous membranes may also be formed by the addition of pore-formers as disclosed in U.S. Pat. No. 4,612,008. In addition, vapor-Permeable coatings may even be formed from extremely hydrophobic materials such as polyethylene or polyvinylidene difluorid that, when dense, are essentially water-impermeable, as long as such coatings are porous. Materials useful in forming the coating include but are not limited to various grades of acrylic, vinyls, ethers, polyamides, polyesters and cellulosic derivatives that are water-Permeable and water-insoluble at physiologically relevant pHs, or are susceptible to being rendered water-insoluble by chemical alteration such as by crosslinking. Nonlimiting examples of suitable polymers (or crosslinked versions) useful in forming the coating include plasticized, unplasticized and reinforced cellulose acetate (CA), cellulose diacetate, cellulose triacetate, CA propionate, cellulose nitrate, cellulose acetate butyrate (CAB), CA ethyl carbamate, CAP, CA methyl carbamate, CA succinate, cellulose acetate trimellitate (CAT), CA dimethylaminoacetate, CA ethyl carbonate, CA chloroacetate, CA ethyl oxalate, CA methyl sulfonate, CA butyl sulfo-nate, CA p-toluene sulfonate, agar acetate, amylose triacetate, beta glucan acetate, beta glucan triacetate, acetaldehyde dimethyl acetate, triacetate of locust bean gum, hydroxiated ethylene-vinylacetate, EC, PEG, PPG, PEG/PPG copolymers, PVP, HEC, HPC, CMC, CMEC, HPMC, HPMCP, HPMCAS, HPMCAT, poly(acrylic) acids and esters and poly-(methacrylic) acids and esters and copolymers thereof, starch, dextran, dextrin, chitosan, collagen, gelatin, polyalkenes, polyethers, polysulfones, polyethersulfones, polystyrenes, polyvinyl halides, polyvinyl esters and ethers, natural waxes and synthetic waxes. In various embodiments, the coating agent comprises a cellulosic polymer, in particular cellulose ethers, cellulose esters and cellulose ester-ethers, i.e., cellulosic derivatives having a mixture of ester and ether substituents, the coating materials are made or derived from poly(acrylic) acids and esters, poly(methacrylic) acids and esters, and copolymers thereof, the coating agent comprises cellulose acetate, the coating comprises a cellulosic polymer and PEG, the coating comprises cellulose acetate and PEG.

Coating is conducted in conventional fashion, typically by dissolving or suspending the coating material in a solvent and then coating by dipping, spray coating or by pan-coating. In certain embodiments, the coating solution contains 5 to 15 wt % polymer. Typical solvents useful with the cellulosic polymers mentioned above include but are not limited to acetone, methyl acetate, ethyl acetate, isopropyl acetate, n-butyl acetate, methyl isobutyl ketone, methyl propyl ketone, ethylene glycol monoethyl ether, ethylene glycol monoethyl acetate, methylene dichloride, ethylene dichloride, propylene dichloride, nitroethane, nitropropane, tetrachloroethane, 1,4-dioxane, tetrahydrofuran, diglyme, water, and mixtures thereof. Pore-formers and non-solvents (such as water, glycerol and ethanol) or plasticizers (such as diethyl phthalate) may also be added in any amount as long as the polymer remains soluble at the spray temperature. Pore-formers and their use in fabricating coatings are described, for example, in TJS5612059. Coatings may also be hydrophobic microporous layers wherein the pores are substantially filled with a gas and are not wetted by the aqueous medium but are permeable to water vapor, as disclosed, for example, in U.S. Pat. No. 5,798,119. Such hydrophobic but water-vapor permeable coatings are typically composed of hydrophobic polymers such as polyalkenes, polyacrylic acid derivatives, polyethers, polysulfones, polyethersulfones, polystyrenes, polyvinyl halides, polyvinyl esters and ethers, natural waxes and synthetic waxes. Hydrophobic microporous coating materials include but are not limited to polystyrene, polysulfones, polyethersulfones, polyethylene, polypropylene, polyvinyl chloride, polyvinylidene fluoride and polytetrafluoroethylene. Such hydrophobic coatings can be made by known phase inversion methods using any of vapor-quench, liquid quench, thermal processes, leaching soluble material from the coating or by sintering coating particles. In thermal processes, a solution of polymer in a latent solvent is brought to liquid-liquid phase separation in a cooling step. When evaporation of the solvent is not prevented, the resulting membrane will typically be porous. Such coating processes may be conducted by the processes disclosed, for example, in U.S. Pat. No. 4,247,498, U.S. Pat. No. 4,490,431 and U.S. Pat. No. 4,744,906. Osmotic controlled-release devices may be prepared using procedures known in the pharmaceutical arts. See for example, Remington: The Science and Practice of Pharmacy, 20th Edition, 2000.

As further noted above, the agents described herein may be provided in the form of microparticulates, generally ranging in size from about 10 μm to about 2 mm (including, for example, from about 100 μm to 1 mm in diameter). Such multiparticulates may be packaged, for example, in a capsule such as a gelatin capsule or a capsule formed from an aqueous-SOluble polymer such as HPMCAS, HPMC or starch; dosed as a suspension or slurry in a liquid; or they may be formed into a tablet, caplet, or pill by compression or other processes known in the art. Such multiparticulates may be made by any known process, such as wet- and dry-granulation processes, extrusion/spheronization, roller-compaction, melt-congealing, or by spray-coating seed cores. For example, in wet- and dry-granulation processes, the agent described herein and optional excipients may be granulated to form multiparticulates of the desired size. Other excipients, such as a binder (e.g., microcrystalline cellulose), may be blended with the agent to aid in processing and forming the multiparticulates. In the case of wet granulation, a binder such as microcrystalline cellulose may be included in the granulation fluid to aid in forming a suitable multiparticulate. See, for example, Remington: The Science and Practice of Pharmacy, 20″Edition, 2000. In any case, the resulting particles may themselves constitute the therapeutic composition or they may be coated by various film-forming materials such as enteric polymers or water-swellable or water-SOluble polymers, or they may be combined with other excipients or vehicles to aid in dosing to patients.

In certain embodiments, it may be desirable to provide for the immediate release of one or more of the agents described herein, and the controlled release of one or more other agents. For example, in one embodiment, a compound described herein can be provided in an immediate release formulation together with a fibrate (e.g. Tricor) or a CETP inhibitor (e.g. torcetrapib) in a controlled release format. In another embodiment, a compound described herein can be provided together with an HMG CoA reductase inhibitor in an immediate release formulation. For example, a compound described herein can be coformulated with an HMG CoA reductase inhibitor in the immediate release formulation described in WO05/01 1634 (page 29, line 31 to page 33 (entire page). In other embodiments, a compound described herein is provided in a controlled release format together with another agent (e.g. an HMG CoA reductase inhibitor) in an immediate release formulation. In other embodiments, one or more agents described herein (for example, a compound described herein and an HMG CoA reductase inhibitor) can be provided in an immediate release formulation together with one or more other agents (for example, a fibrate and/or torcetrapib) in a controlled release format.

The agents can be administered, e.g., by intravenous injection, intramuscular injection, subcutaneous injection, intraperitoneal injection, topical, sublingual, intraarticular (in the joints), intradermal, buccal, ophthalmic (including intraocular), intranasaly (including using a cannula), or by other routes. The agents can be administered orally, e.g., as a tablet or cachet containing a predetermined amount of the active ingredient, gel, pellet, paste, syrup, bolus, electuary, slurry, capsule, powder, granules, as a solution or a suspension in an aqueous liquid or a non-aqueous liquid, as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion, via a micellar formulation (see, e.g. WO 97/1 1682) via a liposomal formulation (see, e.g., EP 736299,WO 99/59550 and WO 97/13500), via formulations described in WO 03/094886 or in some other form. Orally administered compositions can include binders, lubricants, inert diluents, lubricating, surface active or dispersing agents, flavoring agents, and humectants. Orally administered formulations such as tablets may optionally be coated or scored and may be formulated so as to provide sustained, delayed or controlled release of the active ingredient therein. The agents can also be administered transdermally (i.e. via reservoir-type or matrix-type patches, microneedles, thermal poration, hypodermic needles, iontophoresis, electroporation, ultrasound or other forms of sonophoresis, jet injection, or a combination of any of the preceding methods (Prausnitz et al. 2004, Nature Reviews Drug Discovery 3:115)). The agents can be administered locally, for example, at the site of injury to an injured blood vessel. The agents can be coated on a stent. The agents can be administered using high-velocity transdermal particle injection techniques using the hydrogel particle formulation described in U.S. 20020061336. Additional particle formulations are described in WO 00/45792, WO 00/53 160, and WO 02/19989. An example of a transdermal formulation containing plaster and the absorption promoter dimethylisosorbide can be found in WO 89/04179. WO 96/1 1705 provides formulations suitable for transdermal administration. The agents can be administered in the form a suppository or by other vaginal or rectal means. The agents can be administered in a transmembrane formulation as described in WO 90/07923. The agents can be administered non-invasively via the dehydrated particles described in U.S. Pat. No. 6,485,706. The agent can be administered in an enteric-coated drug formulation as described in WO 02/49621. The agents can be administered intranasaly using the formulation described in U.S. Pat. No. 5,179,079. Formulations suitable for parenteral injection are described in WO 00/62759. The agents can be administered using the casein formulation described in U.S. 20030206939 and WO 00/06108. The agents can be administered using the particulate formulations described in U.S. 20020034536.

The agents, alone or in combination with other suitable components, can be administered by pulmonary route utilizing several techniques including but not limited to intratracheal instillation (delivery of solution into the lungs by syringe), intratracheal delivery of liposomes, insufflation (administration of powder formulation by syringe or any other similar device into the lungs) and aerosol inhalation. Aerosols (e.g., jet or ultrasonic nebulizers, metered-dose inhalers (MDIs), and dry-Powder inhalers (DPIs)) can also be used in intranasal applications. Aerosol formulations are stable dispersions or suspensions of solid material and liquid droplets in a gaseous medium and can be placed into pressurized acceptable propellants, such as hydrofluoroalkanes (HFAs, i.e. HFA-134a and HFA-227, or a mixture thereof), dichlorodifluoromethane (or other chlorofluocarbon propellants such as a mixture of Propellants 11, 12, and/or 114), propane, nitrogen, and the like. Pulmonary formulations may include permeation enhancers such as fatty acids, and saccharides, chelating agents, enzyme inhibitors (e.g., protease inhibitors), adjuvants (e.g., glycocholate, surfactin, span 85, and nafamostat), preservatives (e.g., benzalkonium chloride or chlorobutanol), and ethanol (normally up to 5% but possibly up to 20%, by weight). Ethanol is commonly included in aerosol compositions as it can improve the function of the metering valve and in some cases also improve the stability of the dispersion. Pulmonary formulations may also include surfactants which include but are not limited to bile salts and those described in U.S. Pat. No. 6,524,557 and references therein. The surfactants described in U.S. Pat. No. 6,524,557, e.g., a C8-C16 fatty acid salt, a bile salt, a phospholipid, or alkyl saccharide are advantageous in that some of them also reportedly enhance absorption of the compound in the formulation. Also suitable in the invention are dry powder formulations comprising a therapeutically effective amount of active compound blended with an appropriate carrier and adapted for use in connection with a dry-Powder inhaler. Absorption enhancers which can be added to dry powder formulations of the present invention include those described in U.S. Pat. No. 6,632,456. WO 02/080884 describes new methods for the surface modification of powders. Aerosol formulations may include U.S. Pat. No. 5,230,884, U.S. Pat. No. 5,292,499, WO 017/8694, WO 01/78696, U.S. 2003019437, U.S. 20030165436, and WO 96/40089 (which includes vegetable oil). Sustained release formulations suitable for inhalation are described in U.S. 2001003648 IA1, 20030232019A1, and U.S. 20040018243A1 as well as in WO 01/13891, WO 02/067902, WO 03/072080, and WO 03/079885. Pulmonary formulations containing microparticles are described in WO 03/015750, U.S. 20030008013, and WO 00/00176. Pulmonary formulations containing stable glassy state powder are described in U.S. 20020141945 and U.S. Pat. No. 6,309,671. Other aerosol foπnulations are described in EP 1338272A1 WO 90/09781, U.S. Pat. No. 5,348,730, U.S. Pat. No. 6,436,367, WO 91/04011, and U.S. Pat. No. 6,294,153 and U.S. Pat. No. 6,290,987 describes a liposomal based formulation that can be administered via aerosol or other means. Powder foπnulations for inhalation are described in U.S. 20030053960 and WO 01/60341. The agents can be administered intranasally as described in U.S. 20010038824.

Solutions of medicament in buffered saline and similar vehicles are commonly employed to generate an aerosol in a nebulizer. Simple nebulizers operate on Bernoulli's principle and employ a stream of air or oxygen to generate the spray particles. More complex nebulizers employ ultrasound to create the spray particles. Both types are well known in the art and are described in standard textbooks of pharmacy such as Sprowls' American Pharmacy and Remington's The Science and Practice of Pharmacy. Other devices for generating aerosols employ compressed gases, usually hydrofluorocarbons and chlorofluorocarbons, which are mixed with the medicament and any necessary excipients in a pressurized container, these devices are likewise described in standard textbooks such as Sprowls and Remington.

The agent can be incorporated into a liposome to improve half-life. The agent can also be conjugated to polyethylene glycol (PEG) chains. Methods for pegylation and additional formulations containing PEG-conjugates (i.e. PEG-based hydrogels, PEG modified liposomes) can be found in Harris and Chess, Nature Reviews Drug Discovery 2: 214-221 and the references therein. The agent can be administered via a nanocochleate or cochleate delivery vehicle (BioDelivery Sciences International). The agents can be delivered transmucosally (i.e. across a mucosal surface such as the vagina, eye or nose) using formulations such as that described in U.S. Pat. No. 5,204,108. The agents can be formulated in microcapsules as described in WO 88/01 165. The agent can be administered intra-orally using the formulations described in U.S. 20020055496, WO 00/47203, and U.S. Pat. No. 6,495,120. The agent can be delivered using nanoemulsion formulations described in WO 01/91728A2.

Administration and Formulation of Combitherapy Protein/Peptide Agents

Some of the agents used in combitherapy with compounds described herein are proteins (e.g. nitric oxide synthase isoforms, HDL associated proteins such as ApoA-I or Apo A-I Milano) or peptides (e.g. peptides which mitigates one or more symptoms of atherosclerosis, peptides and peptide analogues that mimic the structural and pharmacological properties of human ApoA-I, Exenatide®). In some embodiments, the recombinant or purified protein is administered together with a compound described herein. In alternative embodiments, genes encoding the protein or peptide to be delivered may be administered, rather than the protein. Gene transfer can be obtained using direct transfer of genetic material, in a plasmid or viral vector, or via transfer of genetic material in cells or carriers such as cationic liposomes. Such methods are well known in the art and readily adaptable for use in the therapies described herein. For example, studies by Wolff et al., Biotechniques 11:474-85 (1991), demonstrate injection of naked DNA into muscle allows long term and low expression levels of proteins coded for within the DNA sequence. Administration of naked DNA to smooth muscle layers can be achieved by use of an intramural device, such as an INFILTRATOR™ and allow expression of the proteins or their alpha helical domains to treat the injured vessel. Transfer vectors can be any nucleotide construction used to deliver genes into cells (e.g., a plasmid), or as part of a general strategy to deliver genes, e.g., as part of recombinant retrovirus or adenovirus (Ram et al. Cancer Res. 53:83-88, (1993)). Appropriate means for transfection, including viral vectors, chemical transfectants, or physico-mechanical methods such as electroporation and direct diffusion of DNA, are described by, for example, Wolff, J. A., et al., Science, 247, 1465-1468, (1990); and Wolff, J. A. Nature, 352, 815-818, (1991). Plasmid or viral vectors are agents that transport the gene into a cell without degradation and may include a promoter yielding expression of the gene in the cell into which it is delivered. In certain embodiments vectors are derived from either a virus or a retrovirus. Viral vectors include but are not limited to those derived from Adenovirus, Adeno-associated virus, Herpes virus, Vaccinia virus, Polio virus, AIDS virus, neuronal trophic virus, Sindbis and other RNA viruses, including these viruses with the HIV backbone. Vectors from other viral families which share the properties of these viruses may make them suitable for use as vectors. Retroviral vectors include but are not limited to those derived from include Murine Maloney Leukemia virus, MMLV, and retroviruses that express the desirable properties of MMLV as a vector. In certain emobodiments where non-Proliferating cells are involved, retroviral vectors are not used. Retroviral vectors, in general, are described by Verma, I. M., Retroviral vectors for gene transfer. In MICROBIOLOGY-1985, American Society for Microbiology, pp. 229-232, Washington, (1985). Examples of methods for using retroviral vectors for gene therapy are described in U.S. Pat. No. 4,868,116, U.S. Pat. No. 4,980,286, WO90/02806, WO 89/07136 and Mulligan, (Science 260:926-932 (1993)).

Adenovirus vectors are relatively stable and easy to work with, have high titers, and can be delivered in aerosol formulation, and can transfect non-dividing cells. The construction of replication-defective adenoviruses has been described (Berkner et al., J. Virology 61:1213-1220 (1987); Massie et al., MoI. Cell. Biol. 6:2872-2883 (1986); Haj-Ahmad et al., J. Virology 51:261-21′4 (1986); Davidson et al., J. Virology 61:1226-1239 (1987); Zhang “Generation and identification of recombinant adenovirus by liposome-mediated transfection and PCR analysis” BioTechniques 15:868-872 (1993)). Adenoviral derived vectors are limited in the extent to which they can spread to other cell types, since they can replicate within an initial infected cell, but are unable to form new infectious viral particles. Recombinant adenoviruses have been shown to achieve high efficiency gene transfer after direct, in vivo delivery to airway epithelium, hepatocytes, vascular endothelium, CNS parenchyma and a number of other tissue sites (Morsy, J. Clin. Invest. 92: 1580-1586 (1993); Kirshenbaum, J. Clin. Invest. 92:381-387 (1993); Roessler, J. Clin. Invest. 92:1085-1092 (1993); Moullier, Nature Genetics 4:154-159 (1993); La SaUe, Science 259:988-990 (1993); Gomez-Foix, J. Biol. Chem. 267:25129-25134 (1992); Rich, Human Gene Therapy 4:461-476 (1993); Zabner, Nature Genetics 6:75-83 (1994); Guzman, Circulation Research 73:1201-1207 (1993); Bout, Human Gene Therapy 5:3-10 (1994); Zabner, Cell 75:207-216 (1993); Caillaud, Eur. J. Neuroscience 5:1287-1291 (1993); and Ragot, J. Gen. Virology 74:501-507 (1993)). Pox viral vectors can be used in the gene transfer techniques described herein. In certain embodiment the viral/retroviral vector used in the gene transfer techniques described herein have been engineered so as to suppress the immune response of the host organism, elicited by the viral antigens. In certain embodiments, these vectors carry coding regions for Interleukin 8 or 10. In certain embodiments, the viral/retroviral vectors described herein have one or more of the early genes removed and a gene or gene/promotor cassette inserted into the viral genome in place of the removed viral DNA.

The inserted genes in viral/retroviral vectors usually contain promoters, and/or enhancers to help control the expression of the desired gene product. A promoter is generally a sequence or sequences of DNA that function when in a relatively fixed location in regard to the transcription start site. A promoter contains core elements required for basic interaction of RNA polymerase and transcription factors, and may contain upstream elements and response elements. Promoters controlling transcription from vectors in mammalian host cells may be obtained from various sources, for example, the genomes of viruses such as: polyoma, Simian Virus 40 (SV40), adenovirus, retroviruses, hepatitis-B virus and most preferably cytomegalovirus, or from heterologous mammalian promoters, e.g. beta actin promoter. The early and late promoters of the SV40 virus are conveniently obtained as an SV40 restriction fragment which also contains the SV40 viral origin of replication (Fiers et al., Nature, 273: 113 (1978)). The immediate early promoter of the human cytomegalovirus is conveniently obtained as a Hindiπ E restriction fragment (Greenway, P. J. et al., Gene 18:355-360 (1982)). Promoters from the host cell (to which the viral vector is being transferred) or related species also are useful herein.\

Enhancer generally refers to a sequence of DNA that functions at no fixed distance from the transcription start site and can be either 5′ (Laimins, L. et al., Proc. Natl. Acad. Sci. 78:993 (1981)) or 3¹(Lusky, M. L., et al., Mol. Cell Bio. 3:1108 (1983)) to the transcription unit. Furthermore, enhancers can be within an intron (Banerji, J. L. et al., Cell 33:729 (1983)) as well as within the coding sequence itself (Osborne, T. F., et al., Mol. Cell Bio. 4:1293 (1984)). They are usually between 10 and 300 bp in length, and they function in cis. Enhancers function to increase transcription from nearby promoters. Enhancers also often contain response elements that mediate the regulation of transcription. Promoters can also contain response elements that mediate the regulation of transcription. Enhancers often determine the regulation of expression of a gene. While many enhancer sequences are now known from mammalian genes (globin, elastase, albumin, α-fetoprotein and insulin), typically one will use an enhancer from a eukaryotic cell virus. Enhancers include but are not limited to the SV 40 enhancer on the late side of the replication origin (bp 100-270), the cytomegalovirus early promoter enhancer, the polyoma enhancer on the late side of the replication origin, and adenovirus enhancers.

The promotor and/or enhancer may be specifically activated either by light or specific chemical events which trigger their function. Systems can be regulated by reagents such as tetracycline and dexamethasone. There are also ways to enhance viral vector gene expression by exposure to irradiation, such as gamma irradiation, or alkylating chemotherapy drugs.

In certain embodiments, the promoter and/or enhancer region act as a constitutive promoter and/or enhancer to maximize expression of the region of the transcription unit to be transcribed. In certain embodiments the promoter and/or enhancer region is active in all eukaryotic cell types. Promoters include but are not limited to the CMV promoter (650 bases), SV40 promoters, cytomegalovirus (full length promoter), and retroviral vector LTF.

Expression vectors used in eukaryotic host cells may also contain sequences necessary for the termination of transcription which may affect mRNA expression. These regions are transcribed as polyadenylated segments in the untranslated portion of the mPvNA encoding tissue factor protein. The 3′ untranslated regions also include transcription termination sites. In certain embodiments, the transcription unit also contains a polyadenylation region (e.g. that derived from the SV40 early polyadenylation signal consisting of about 400 bases). One benefit of this region is that it increases the likelihood that the transcribed unit will be processed and transported like mRNA. The identification and use of polyadenylation signals in expression constructs is well established. In certain embodiments, homologous polyadenylation signals are used in the transgene constructs. In certain embodiments, the transcribed units contain other standard sequences alone or in combination with the above sequences improve expression from, or stability of, the construct.

The viral/retroviral vectors can include nucleic acid sequence encoding a marker product. This marker product is used to determine if the gene has been delivered to the cell and once delivered is being expressed. Examples of suitable selectable markers for mammalian cells are dihydrofolate reductase (DHFR), thymidine kinase, neomycin, neomycin analog G418, hydro-mycin, and puromycin. When such selectable markers are successfully transferred into a mamma-lian host cell, the transformed mammalian host cell can survive if placed under selective pressure.

Kits

The compounds and pharmaceutical formulations described herein may be contained in a kit. The kit may include single or multiple doses of two or more agents, each packaged or formulated individually, or single or multiple doses of two or more agents packaged or formulated in combination. Thus, one or more agents can be present in first container, and the kit can optionally include one or more agents in a second container. The container or containers are placed within a package, and the package can optionally include administration or dosage instructions. A kit can include additional components such as syringes or other means for administering the agents as well as diluents or other means for formulation. Thus, the kits can comprise: a) a pharmaceutical composition comprising a compound described herein and a pharmaceutically acceptable carrier, vehicle or diluent; and b) a container or packaging. The kits may optionally comprise instructions describing a method of using the pharmaceutical compositions in one or more of the methods described herein (e.g. preventing or treating vascular diseases/disorders and conditions (including but not limited to arteriosclerosis, atherosclerosis, cardiovascular disease, cerebrovascular disease, renovascular disease, mesenteric vascular disease, pulmonary vascular disease, ocular vascular disease and peripheral vascular disease), hyperlipidemia (including but not limited to hypercholesterolemia, hypertriglyceridemia, sitosterolemia), hypertension, angina, cardiac arrhythmias, congestive heart failure, and stroke). The kit may optionally comprise a second pharmaceutical composition comprising one or more additional agents chosen from (1) a dyslipidemic agent, (2) an anti-diabetic agent, (3) an anti-hypertensive agent, (4) an anti-obesity agent, (5) an agent used to treat autoimmune disorders, (6) an agent used to treat demylenation and its associated disorders, (7) an agent used to treat Alzheimer's disease, (8) a blood modifier, (9) a hormone replacement agent/composition, (10) a chemotherapeutic agent, (11) a peptide which mitigates one or more symptoms of atherosclerosis, (12) an anti-cancer agent, and (13) an agent used to treat bone loss and associated disorders and a pharmaceutically acceptable carrier, vehicle or diluent. The pharmaceutical composition comprising the compound described herein and the second pharmaceutical composition contained in the kit may be optionally combined in the same pharmaceutical composition.

A kit includes a container or packaging for containing the pharmaceutical compositions and may also include divided containers such as a divided bottle or a divided foil packet. The container can be, for example a paper or cardboard box, a glass or plastic bottle or jar, a re-sealable bag (for example, to hold a “refill” of tablets for placement into a different container), or a blister pack with individual doses for pressing out of the pack according to a therapeutic schedule. It is feasible that more than one container can be used together in a single package to market a single dosage form. For example, tablets may be contained in a bottle which is in turn contained within a box.

An example of a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process, recesses are formed in the plastic foil. The recesses have the size and shape of individual tablets or capsules to be packed or may have the size and shape to accommodate multiple tablets and/or capsules to be packed. Next, the tablets or capsules are placed in the recesses accordingly and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are individually sealed or collectively sealed, as desired, in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening.

It may be desirable to provide a written memory aid containing information and/or instructions for the physician, pharmacist or subject regarding when the medication is to be taken. A “daily dose” can be a single tablet or capsule or several tablets or capsules to be taken on a given day. When the kit contains separate compositions, a daily dose of one or more compositions of the kit can consist of one tablet or capsule while a daily dose of another one or more compositions of the kit can consist of several tablets or capsules. A kit can take the form of a dispenser designed to dispense the daily doses one at a time in the order of their intended use. The dispenser can be equipped with a memory-aid, so as to further facilitate compliance with the regimen. An example of such a memory-aid is a mechanical counter which indicates the number of daily doses that have been dispensed. Another example of such a memory-aid is a battery-Powered micro-chip memory coupled with a liquid crystal readout, or audible reminder signal which, for example, reads out the date that the last daily dose has been taken and/or reminds one when the next dose is to be taken.

In Vivo Assay of Hypolipidemic Agents using the Rat Cholesterol Absorption Model. This model is based on models described by Burnett et al (2002), Bioorg. Med. Chem. Lett. 2002 Feb. 11; 12(3):315-8 and J. Lipid Res. 1999 October: 40f10): 1747-57. Female Sprague-Dawley rats weighing 150-250g are separated into groups of 3 and fasted overnight.

After three hours, 200 μL serum is collected, vortexed with scintillation fluid, and measured for radioactivity in a scintillation counter. Percent inhibition is defined as 100*(1−C_te_st/C_ctri), where C_testand C_ctrirefer to ³H levels in serum for the test compound and for the vehicle only control, respectively. Percent inhibition values are reported for a fixed dose. The ED₅₀is the dose at which the half-maximal effect on serum ³H levels is observed for a given test compound.

Diet consumption is monitored to determine dietary cholesterol exposure in the face of test compounds. The animals are dosed with the test compound once daily beginning with the initiation of diet. Dosing is by oral gavage of 0.2 mL of corn oil alone (control group) or solution (or suspension) of test compound in corn oil. All animals moribund or in poor physical condition are euthanized. After seven days, the animals are anesthetized by intramuscular (IM) injection of ketamine and sacrificed by decapitation. Blood is collected into vacutainer tubes containing EDTA for plasma lipid analysis and the liver excised for tissue lipid analysis. Lipid analysis is conducted as per published procedures [Schnitzer-Polokoff, R., et al, Comp. Biochem.

Pharmacokinetics: To study the pharmacokinetics of compounds, bioavailability studies are carried out in various test animals. Compounds are prepared in suitable formulations for oral and intravenous administration. Compounds are administered via intravenous injection (tail vein (rat), femoral vain (hamster), peripheral vain (monkey), cephalic vein (dog)) and orally (via a capsule (dogs) or gavage (all others)) to independent groups of test animals which are either fasted overnight or non-fasted. Serum or plasma is collected at various time points and assayed for the presence of compounds using an LC/MS/MS detection method. Experiment samples are either diluted 15-fold in 30% acetonitrile in water, injected onto an in-line sample extraction cartridge (Waters Oasis HLB Direct Connect) and loaded onto a reverse phase HPLC column fitted with a appropriate guard column or prepared using a protein crash, dried under nitrogen, resuspended in 30% acetonitrile in water and loaded onto a reverse phase HPLC column fitted with a appropriate guard column. Samples are eluted from the reverse phase HPLC column with a gradient. A Micromass Quattro Micro (Waters Corporation, Milford, Mass.) triple quadrupole mass spectrometer operated in MRM mode is used for detection. Concentrations are calculated based on a standard concentration curve of compound or standard curves generated using peak area ratio of compound to internal standard vs. concentration. MassLynx software (Waters, Corporation, Milford, Mass.) is used to calculate the absolute concentration of test compound in each serum or plasma sample. A concentration versus time plot is generated from the data in Microsoft Excel, Summit Software PK Solutions 2.0, GraphPad Prism (GraphPad Software, Inc., San Diego, Calif.) or WinNonlin Professional Version 4.1 (Pharsight Corporation, Mountain View, Calif.) to generate pharmacokinetic curves. An area under the curve (AUC_n, n=length of experiment in minutes or hours) is calculated from the concentration vs. time data by software using the linear trapezoid method for both the orally and intravenously dosed animals. Oral Bioavailability (F) over the length of the experiment is calculated using the equation::

F=(AUC_oral*Dosei._v.)/(AUQ._V.*Dose_oral).

Determination of Acyl Coenzyme A: Cholesterol Acyltransferase (ACAT) Inhibition Activity

The ability of compounds of the invention to inhibit acyl-coenzyme A: cholesterol acyltransferase (ACAT) activity is assayed by measuring cholesterol esterification in human HepG2 and Caco2 cells. ACAT activity is measured by following the conversion of ¹⁴C-oleic acid to ¹⁴C-cholesteryl oleate in an assay based on Junquero, et al. 2001 Biochem Pharmacol 61:97-108 and Sugiyama, et al. Atherosclerosis 118:145-53. Cells are propagated in Eagle's Minimum Essential Medium (EMEM) supplemented with fetal bovine serum (10% for HepG2 cells; 20% for Caco2 cells) and 2 mM L-glutamine. All incubations are performed at 37° C. in air with 5% CO₂. In preparation for each experiment, cells are seeded in 6-well plates and allowed to grow to 90-95% confluency. All treatments are performed in duplicate. Inhibitors are pre-incubated with cells for 4 h. The assay is initiated by adding ¹⁴C-oleate/bovine serum albumin solution to each assay well and incubating an additional 2 h at 37° C. Cell monolayers are extracted with 2 mL 3:2 hexane:isopropanol at room temperature for 30 min. Extracts are dried down under nitrogen and dissolved in 75 fL chloroform. Formation of ¹⁴C-cholesteryl oleate is determined by separation of the ACAT assay reaction products by thin-layer chromatography (TLC) and visualization by phosphorimaging. Percent inhibition is calculated for each compound dose, and IC₅0 values are determined using GraphPad Prism by regression analysis of percent inhibition plotted as a function of the logarithmic value of the sample concentration. FIG. 2 is a table of the ACAT activity of several compounds of the invention assayed one or more times. Values for the known ACAT inhibitor, N-[4-(2-chlorophenyl)-6,7-dimethyl-3-quinolyl]-N′-(2,4-difluorophenyl)urea (TMP-1 53) and the known cholesterol absorption inhibitor molecule, (3R,4S)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)azetidin-2-one can also be determined.

Competitive Binding Assays

The ability of compounds of the invention to bind and compete for specific binding to a receptor in the hamster small intestine is tested. Competition binding to hamster small intestine is determined by using an in vivo assay based on Hernandez et al. 2000 (Biochim Biophys Acta 1486:232-242) in which radiolabeled compound is administered to hamsters in the presence and absence of unlabeled, test, competitor compounds. In this experiment, a compound of the invention, can be tritiated and used as a radioligand. Corresponding unlabeled compound in 1200-fold excess is used to demonstrate that the observed binding is specific. Other compounds of the invention and a known cholesterol absorption inhibitor, (3R,4S)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)azetidin-2-one, are evaluated for their ability to compete for binding of the tritiated radioligand when administered in 1200-fold excess. Golden Syrian hamsters are fasted overnight prior to dosing. Animals are dosed by oral gavage with 0.5 ml of either vehicle or vehicle containing 0.35 mg/kg test compound. One hour later, animals are dosed by oral gavage with 5 μCi tritiated radioligand with vehicle or vehicle containing 0.35 mg/kg test compound as above. Three hours after administration of the tritiated radioligand, animals are euthanized by CO₂overdose, the small intestine dissected, flushed with cold saline, and placed into an empty tube on ice. The small intestine is cut into ˜6 cm segments. The intestinal epithelial mucosa is extruded from each segment, homogenized in PBS, and the radioactivity in the homogenate is counted by liquid scintillation counting. Results are normalized for protein content of the homogenates. Tritiated radioligand binding to the hamster small intestine in the presence and absence of test compound is determined by calculating the average bound radioactivity per mg of protein (DPM/mg) for each treatment group. Percent tritiated radioligand binding is calculated for each compound using the formulas:

Bound Radioactivity(DPM/mg)=Radioactivity(DPM)/Total Protein(mg)

Percent ³H Binding vs Vehicle Control=100%*((Bound Radioactivity)_competitoI/(Bound Radioactivity)_Vehicie)

Statistical analysis is performed using an unpaired, two-tailed, Student's t-test (GraphPad Prism).

A desirable medicament would inhibit cholesterol absorption without affecting the acute absorption of other important molecules of dietary origin. Such a cholesterol absorption inhibitor would not interfere with the absorption of triglyceride, progesterone, ethinyl estradiol, vitamin A, vitamin D, or taurocholic acid. For example, cholestyramine, which is in clinical use to lower serum cholesterol, sequesters bile acids in the intestine, ultimately leading to a decrease in plasma cholesterol by upregulating the synthesis of bile acids from cholesterol in the liver. Two side effects of cholestyramine are gastrointestinal discomfort and the sequestration of fat-SOluble vitamins. On the other hand, ezetimibe, a known cholesterol absorption inhibitor, does not appear to affect fat-SOluble vitamin absorption in humans. In addition, ezetimibe does not inhibit the absorption of taurocholic acid, suggesting that certain cholesterol absorption inhibitors can lower serum cholesterol without inhibiting the ileal Na⁺/bile acid cotransporter.

Retinol, Taurocholic Acid, Progesterone, Sitostanol, and Cholesterol Absorption Assays

The effects of acute oral administration of several compounds of the invention on retinol, taurocholic acid, and progesterone absorption are studied in female Sprague Dawley rats. Groups of 5 rats received 10 mg/kg of test compound or vehicle (olive oil) via oral gavage. Test compounds are administered 30 minutes prior to oral administration of ¹⁴C-cholesterol (5 μCi) in addition to either ³H-retinol (3 μCi), ³H-taurocholic acid (3 μCi), ³H-Progesterone (3 μCi), or ³H-sitostanol (3 μCi) constituted in olive oil (300 μL). Blood is sampled from all animals via the retro-orbital sinus under isoflurane anesthesia three hours after the administration of the radiolabeled cocktail and again at 24 hours. Serum radioactivity (DPM) is measured and the percent absorption (% absorption) is calculated as:

average dpm treated group/average dpm control group×100.

Assays can also be performed using the known cholesterol absorption inhibitor molecule, (3R,4S)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)azetidin-2-one is for comparison.

Additivity Assay

The effects of compounds of the invention either alone and in combination with the known cholesterol absorption inhibitor, (3R,4S)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)azetidin-2-one can be studied in one or more of the in vivo animal models above. For example, in the case of the rat cholesterol absorption model, groups of five rats receive each of the compounds of the invention alone (1 mg/kg) or in combination with (3R,4S)-1-(4-fluorophenyl)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-(4-hydroxyphenyl)azetidin-2-one (each at 1 mg/kg) or vehicle (olive oil) via oral gavage. Serum radioactivity (DPM) is measured and the average values are plotted.

In general, the compounds of the present invention may be prepared by the methods illustrated in the general reaction schemes as, for example, described below, or by modifications thereof, using readily available starting materials, reagents and conventional synthesis procedures. In these reactions, it is also possible to make use of variants that are in themselves known, but are not mentioned here.

The preparation of the mono-methoxy analogue 10 starts by the condensation of commercially available 2-hydroxy-4-methoxybenzaldehyde (1) with aniline (2) to produce the corresponding imine. Protection of the hydroxyl moiety of the imine was accomplished by treatment with benzyl bromide and potassium carbonate in DMF to provide 3. Treatment of 4 (prepared according to the method of B. A. Shinkre, V. G. Puranik, B, M. Bhawal, A. Deshmukh, TetrahedronAsymmetry 2003, 14, 453) with triphosgene [(Cl₃CO)₂CO] and triethylamine in the presence of 3 provides the beta-lactam 5. A solution of ketal 5 is dissolved in tetrahydrofuran and water with a catalytic amount of para-toluenesulfonic acid to effect hydrolysis to the alcohol 6. The alcohol 6 is then treated with sodium methoxide in methanol to effect conversion to the methyl ester with beta-lactam ring opening. Reaction of the resulting alcohol with triphosgene in the presence of diisopropylethylamine and N,N-dimethylaminopyridine (DMAP) gives the oxazolidinone 7. The ester moiety of 7 is then converted into the corresponding hydroxymethyl substituent upon treatment with sodium cyanoborohydride. Swern oxidation converts the hydroxymethyl substituent into the corresponding aldehyde which is then reacted with the Wittig reagent 1-(4-fluorophenyl)-2-triphenyl-λ⁵-phosphanylidene)-ethanone to give the ketone 8. Catalytic hydrogenation of 8 over palladium on carbon removes the benzyl protecting group and reduces the double bond to give ketone 9 which is reduced with borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS) to give the desired compound 10.

In the following scheme, 2,4-dihydroxybenzaldehyde was converted to the corresponding dibenzyl ether (11) upon treatment with benzyl bromide and potassium carbonate in methyl ethyl ketone. Treatment of 11 with aniline (2) resulted in the formation of the corresponding imine 12 in good yield. Treatment of 4 with triphosgene [(Cl₃CO)₂CO] and triethylamine in the presence of 12 provides the beta-lactam 13. A solution of ketal 13 is dissolved in tetrahydrofuran and water with a catalytic amount of pαrø-toluenesulfonic acid to effect hydrolysis to the alcohol 14. The alcohol 14 is then treated with sodium methoxide in methanol to effect conversion to the methyl ester with beta-lactam ring opening. Reaction of the resulting alcohol with triphosgene in the presence of diisopropylethylamine and N N-dimethylaminopyridine gives the oxazolidinone 15. The ester moiety of 15 is then converted into the corresponding hydroxymethyl substituent upon treatment with sodium cyanoborohydride. Swern oxidation converts the hydroxymethyl substituent into the corresponding aldehyde which is then reacted with the Wittig reagent 1-(4-fluorophenyl)-2-triphenyl-λ⁵-phosphanylidene)-ethanone to give the ketone 16. Catalytic hydrogenation of 16 over palladium on carbon removes the benzyl protecting groups and reduces the double bond to give ketone 17 which is reduced with borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS) to give the desired compound 18.

In the following scheme 2-hydroxy-4-bromobenzaldehyde 19 was prepared by reaction of 3-bromophenol with paraformaldehyde in the presence of magnesium chloride and excess triethylamine in acetonitrile. Treatment of 19 with aniline (2) resulted in the formation of the corresponding imine in good yield, which is converted to the corresponding benzyl ether (20) upon treatment with benzyl bromide and potassium carbonate in N,N-dimethylformamide (DMF). Treatment of 4 with triphosgene [(Cl₃CO)₂CO] and triethylamine in the presence of 20 provides the beta-lactam 21. A solution of ketal 21 is dissolved in tetrahydrofuran and water with a catalytic amount of pαrø-toluenesulfonic acid to effect hydrolysis to the alcohol 22. The alcohol 22 is then treated with sodium methoxide in methanol to effect conversion to the methyl ester with beta-lactam ring opening. Reaction of the resulting alcohol with triphosgene in the presence of diisopropylethylamine and N,N-dimethylaminopyridine gives the oxazolidinone 23. The ester moiety of 23 is then converted into the corresponding hydroxymethyl substituent upon treatment with sodium cyanoborohydride. Swern oxidation converts the hydroxymethyl substituent into the corresponding aldehyde which is then reacted with the Wittig reagent 1-(4-fluorophenyl)-2-triphenyl-λ⁵-phosphanylidene)-ethanone to give the ketone 24. Suzuki coupling of 24 with 3-hydroxyphenylboronic acid gives the desired biphenyl derivative 25. Catalytic hydrogenation of 25 over palladium on carbon removes the benzyl protecting group and reduces the double bond to give ketone 26 which is reduced with borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS) to give the desired compound 27.

In the scheme shown below is the description of a phosphonic acid containing compound. The sequence begins with the conversion of commercially available 4-bromophenylboronic acid (28) to the corresponding pinacol ester 29 upon stirring with pinacol in toluene. Treatment of 29 with a mixture of trimethylphosphite, AIBN, and tris(trimethylsilyl)silane produced the dimethylphosphonate derivative 30 in good yield. Suzuki coupling of 30 with 24 gives the biphenyl derivative 31. Catalytic hydrogenation of 31 over palladium on carbon removes the ben2yl protecting group and reduces the double bond to give ketone 32. Reduction of 32 with borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS) followed by treatment with bromotrimethylsilane and an aqueous workup gives compound 33.

In the scheme shown below, a C-glycosyl compound is described. The sequence commences with the reaction of peracetyl D-glucose with 33% HBr in acetic acid to produce the anomeric bromide 34. Treatment of 34 with excess Grignard reagent 35, generated from 1,4-dibromobenzene and magnesium, followed by treatment of the crude product with acetic anhydride in pyridine provides the desired bromophenyl derivative 36. Conversion of 36 to the corresponding pinacol boronate ester 38 is accomplished by reaction with bis(pinicolato)diboron (37) under the influence of palladium catalysis. Suzuki coupling of 38 with 24 gives the expected biphenyl derivative 39. Catalytic hydrogenation of 39 over palladium on carbon removes the benzyl protecting group and reduces the double bond to give ketone 40. Reduction of 40 with borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS) followed by solvolysis in aqueous methanol with triethylamine gives compound 41.

If desired, the compounds 47-51 can also be prepared by the procedures described above by substituting sodium borohydride for borane dimethylsulfide complex in the presence of a catalytic amount of tetrahydro-1-methyl-3,3-diphenyl-1H,₃H-pyrrolo[1,2-c][1,3,2]oxazaborole, (R-CBS).

Commercially available 4-(4-fluorobenzoyl)butyric acid (52) was converted to the corresponding mixed anhydride by treatment with pivaloyl chloride and DMAP in DMF and then coupled to (5)-4-benzyl-2-oxazolidinone to afford the imide (53). Treatment of 53 with borane dimethylsulfide complex in the presence of a catalytic amount of (R)-1-methyl-3,3-diphenyltetrahydro-3H-pyrrolo[1,2-c][1,3,2]oxazaborole produced the desired (4S)-4-benzyl-3-[(55)-5-(4-fluorophenyl)-5-hydroxypentanoyl]-1,3-oxazolidin-2-one (54a) in good yield. Protection of the benzylic alcohol as the TBS ether was effected by reaction with tert-butyldimethylsilyl chloride in the presence of imidazole as a base to provide 54b in good yield.

Treatment of 54b with titanium tetrachloride and N-ethyldiisopropylamine followed by treatment with 12 effects enantiospecific condensation to provide 55. Treatment of 55 with excess N,0-bistrimethylsilyl-acetamide followed by a catalytic amount of tetrabutylammonium fluoride hydrate results in ring closure to the desired beta-lactam (56) while maintaining the TBS protecting group on the benzylic alcohol. Catalytic hydrogenation of 56 over palladium on carbon gives the deprotected phenol 57. Treatment of 57 with Lawesson's reagent coverts the beta-lactam into a thioazetidinone.
