Combinations of nicotinic acid and derivatives thereof and sterol absorption inhibitor(s) and treatments for vascular indications

Description

FIELD OF THE INVENTION

[0002] The present invention relates to compositions and therapeutic combinations comprising agonists of the HM74A receptor, such as nicotinic acid or derivatives thereof, and certain sterol absorption inhibitors for treating hyperlipidemic conditions such as are associated with atherosclerosis, hypercholesterolemia and other vascular conditions in subjects.

BACKGROUND OF THE INVENTION

[0003] Atherosclerotic coronary heart disease (CHD) represents the major cause for death and vascular morbidity in the western world. Risk factors for atherosclerotic coronary heart disease include hypertension, diabetes mellitus, family history, male gender, cigarette smoke and serum cholesterol. A total cholesterol level in excess of 225-250 mg/dl is associated with significant elevation of risk of CHD.

[0004] Cholesteryl esters are a major component of atherosclerotic lesions and the major storage form of cholesterol in arterial wall cells. Formation of cholesteryl esters is also a key step in the intestinal absorption of dietary cholesterol. Thus, inhibition of cholesteryl ester formation and reduction of serum cholesterol can inhibit the progression of atherosclerotic lesion formation, decrease the accumulation of cholesteryl esters in the arterial wall, and block the intestinal absorption of dietary cholesterol.

[0005] The regulation of whole-body cholesterol homeostasis in mammals and animals involves the regulation of dietary cholesterol and modulation of cholesterol biosynthesis, bile acid biosynthesis and the catabolism of the cholesterol-containing plasma lipoproteins. The liver is the major organ responsible for cholesterol biosynthesis and catabolism and, for this reason, it is a prime determinant of plasma cholesterol levels. The liver is the site of synthesis and secretion of very low density lipoproteins (VLDL) which are subsequently metabolized to low density lipoproteins (LDL) in the circulation. LDL are the predominant cholesterol-carrying lipoproteins in the plasma and an increase in their concentration is correlated with increased atherosclerosis. When intestinal cholesterol absorption is reduced, by whatever means, less cholesterol is delivered to the liver. The consequence of this action is decreased hepatic lipoprotein (VLDL) production and an increase in the hepatic clearance of plasma cholesterol, mostly as LDL. Thus, the net effect of inhibiting intestinal cholesterol absorption is a decrease in plasma cholesterol levels.

[0006] Nicotinic acid and its derivatives can inhibit hepatic production of VLDL and its metabolite LDL and increases HDL and apo A-1 levels.

Nos. 5,846,966 and 5,661,145, respectively, disclose hydroxy-substituted azetidinone compounds or substituted β-lactam compounds in combination with HMG CoA reductase inhibitors for preventing or treating atherosclerosis and reducing plasma cholesterol levels.

[0008] PCT Patent Application No. WO 00/38725 discloses cardiovascular therapeutic combinations including an ileal bile acid transport inhibitor or cholesteryl ester transport protein inhibitor in combination with a fibric acid derivative, nicotinic acid derivative, microsomal triglyceride transfer protein inhibitor, cholesterol absorption antagonist, phytosterol, stanol, antihypertensive agent or bile acid sequestrant.

DETAILED DESCRIPTION

[0220] In one embodiment, the present invention is directed to compositions, pharmaceutical compositions, therapeutic combinations, kits and methods of treatment using the same comprising at least one (one or more) HM74A or HM74 receptor agonists and at least one (one or more) of substituted azetidinone sterol absorption inhibitors or substituted β-lactam sterol absorption inhibitors such as are discussed in detail below.

[0221] Non-limiting examples of suitable HM74 and HM74A receptor agonists include nicotinic acid and derivatives thereof, 5-methylpyrazole-3-carboxylic acid and acifran (4,5-dihydro-5-methyl-4-oxo-5-phenyl-2-furan carboxylic acid). These compounds have been identified as agonists of the HM74A or HM74 receptor (Wise et al., J. Biol. Chem. (2003) 278(11): 9869-9874). The nucleotide sequence of human HM74A is disclosed under Genbank/EBI Data Bank Accession No. AY148884 and rat HM74A is disclosed under EMM_patAR098624.

[0222] As used herein, “nicotinic acid derivative” means a compound comprising a pyridine-3-carboxylate structure or a pyrazine-2-carboxylate structure, including acid forms, salts, esters, zwitterions and tautomers, where available. Examples of nicotinic acid derivatives include pyradine-3-acetic acid, 5-methyl nicotinic acid, nicotinuric acid, niceritrol, nicofuranose and acipimox (5-methylpyrazine-2-carboxylic acid 4-oxide). Nicotinic acid and its derivatives inhibit hepatic production of VLDL and its metabolite LDL and increases HDL and apo A-1 levels. An example of a suitable nicotinic acid product is NIASPAN® (niacin extended-release tablets) which are available from Kos.

[0223] One skilled in the art can very easily identify other substances (e.g., nicotinic acid derivatives) which bind to and agonize the HM74A or HM74 receptor. For example, Wise et al. (J. Biol. Chem (2003) 278(11):9869-9874) disclose a labeled nicotine binding assay as well as a [35S]-GTPγS binding assay. Soga et al. (Biochem. Biophys. Res. Comm. (2003) 303:364-369) discloses another radiolabel binding assay using the HM74 receptor which could easily be adapted to the HM74A receptor. Tunaru et al. (Nature Medicine (2003) 9(3): 352-355) discloses a calcium mobilization assay using the HM74 receptor which, similarly, can be adapted to the HM74A receptor. Moreover, FLIPR assays are described generally in U.S. Pat. No. 6,420,183 and may be adapted to the HM74A or HM74 receptor.

[0224] “Subject” means any organism, preferably an animal, more preferably a mammal (e.g., dog, rabbit, mouse, rat, horse, cow, cat, guinea pig, hamster) and even more preferably a human.

[0225] These assays employ conventional laboratory methods which are commonly known in the art. Some of these techniques, for example, are explained in the literature. See, e.g., Sambrook, Fritsch & Maniatis, Molecular Cloninq: A Laboratory Manual, Second Edition (1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (herein “Sambrook, et al., 1989”); DNA Cloning: A Practical Approach, Volumes I and II (D. N. Glover ed. 1985); Oligonucleotide Synthesis (M. J. Gait ed. 1984); Nucleic Acid Hybridization (B. D. Hames & S. J. Higgins eds. (1985)); Transcription And Translation (B. D. Hames & S. J. Higgins, eds. (1984)); Animal Cell Culture (R. I. Freshney, ed. (1986)); Immobilized Cells And Enzymes (IRL Press, (1986)); B. Perbal, A Practical Guide To Molecular Cloning (1984); F. M. Ausubel, et al. (eds.), Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994).

[0226] The HM74 and/or HM74A receptor agonists are administered in a therapeutically effective amount to treat the specified condition, for example a total daily dosage of HM74 and/or HM74A receptor agonists can range from about 500 to about 10,000 mg/day, preferably about 1000 to about 8000 mg/day, and more preferably about 3000 to about 6000 mg/day, given in a single dose or 2-4 divided doses. The exact dose, however, is determined by the attending clinician and is dependent on such factors as the potency of the compound administered, the age, weight, condition and response of the patient.

[0227] The phrase “therapeutically effective amount” means that amount of a therapeutic agent of the composition, such as the HM74 and/or HM74A receptor agonists, sterol absorption inhibitor(s) and pharmacological or therapeutic agents described below, that will elicit a biological or medical response of a tissue, system, subject, animal or mammal that is being sought by the administrator (such as a researcher, doctor or veterinarian) which includes alleviation of the symptoms of the condition or disease being treated and the prevention, slowing or halting of progression of one or more conditions, for example vascular conditions, such as hyperlipidemia (for example atherosclerosis, hypercholesterolemia or sitosterolemia), vascular inflammation, stroke, diabetes, obesity and/or to reduce the level of sterol(s) (such as cholesterol) in the plasma.

[0228] As used herein, “combination therapy” or “therapeutic combination” means the administration of two or more therapeutic agents, such as HM74 or HM74A receptor agonists and sterol absorption inhibitor(s), to prevent or treat a condition, for example a vascular condition, such as hyperlipidaemia (for example atherosclerosis, hypercholesterolemia or sitosterolemia), stroke, diabetes, obesity and/or reduce the level of sterol(s) in the plasma. As used herein, “vascular” comprises cardiovascular, cerebrovascular, peripheral vascular and combinations thereof. Such administration includes coadministration of these therapeutic agents in a substantially simultaneous manner, such as in a single tablet or capsule having a fixed ratio of active ingredients or in multiple, separate capsules for each therapeutic agent. Also, such administration includes use of each type of therapeutic agent in a sequential manner. In either case, the treatment using the combination therapy will provide beneficial effects in treating the condition. A potential advantage of the combination therapy disclosed herein may be a reduction in the required amount of an individual therapeutic compound or the overall total amount of therapeutic compounds that are effective in treating the condition. By using a combination of therapeutic agents, the side effects of the individual compounds can be reduced as compared to a monotherapy, which can improve patient compliance. Also, therapeutic agents can be selected to provide a broader range of complementary effects or complimentary modes of action.

[0229] As discussed above, the compositions, pharmaceutical compositions and therapeutic combinations of the present invention comprise one or more substituted azetidinone or substituted β-lactam sterol or 5α-stanol absorption inhibitors discussed in detail below. As used herein, “sterol absorption inhibitor” means a compound capable of inhibiting the absorption of one or more sterols, including but not limited to cholesterol, phytosterols (such as sitosterol, campesterol, stigmasterol and avenosterol) and mixtures thereof, when administered in a therapeutically effective (sterol absorption inhibiting) amount to a subject. As used herein, “5α-stanol absorption inhibitor” means a compound capable of inhibiting the absorption of one or more 5α-stanols, including, but not limited to, cholestanol, 5α-campestanol, and 5α-sitostanol and mixtures thereof, when administered in a therapeutically effective (5α-stanol absorption inhibiting) amount to a subject.

[0230] In a preferred embodiment, sterol absorption inhibitors useful in the compositions, therapeutic combinations and methods of the present invention are represented by Formula (I):

[0231] or isomers of the compounds of Formula (I), or pharmaceutically acceptable salts or solvates of the compounds of Formula (I) or of the isomers of the compounds of Formula (I) as discussed in detail above.

[0232] As used herein, the term “alkyl” or “lower alkyl” means straight or branched alkyl chains having from 1 to 6 carbon atoms and “alkoxy” means alkoxy groups having 1 to 6 carbon atoms. Non-limiting examples of lower alkyl groups include, for example methyl, ethyl, propyl, and butyl groups.

[0233] “Alkenyl” means straight or branched carbon chains having one or more double bonds in the chain, conjugated or unconjugated. Similarly, “alkynyl” means straight or branched carbon chains having one or more triple bonds in the chain. Where an alkyl, alkenyl or alkynyl chain joins two other variables and is therefore bivalent, the terms alkylene, alkenylene and alkynylene are used.

[0234] “Cycloalkyl” means a saturated carbon ring of 3 to 6 carbon atoms, while “cycloalkylene” refers to a corresponding bivalent ring, wherein the points of attachment to other groups include all positional isomers.

[0235] “Halogeno” refers to fluorine, chlorine, bromine or iodine radicals.

[0236] “Aryl” means phenyl, naphthyl, indenyl, tetrahydronaphthyl or indanyl.

[0237] “Phenylene” means a bivalent phenyl group, including ortho, meta and para-substitution.

[0238] The statements wherein, for example, R, R1, R2 and R3, are said to be independently selected from a group of substituents, mean that R, R1, R2 and R3 are independently selected, but also that where an R, R1, R2 and R3 variable occurs more than once in a molecule, each occurrence is independently selected (e.g., if R is —OR6, wherein R6 is hydrogen, R2 can be —OR6 wherein R6 is lower alkyl). Those skilled in the art will recognize that the size and nature of the substituent(s) will affect the number of substituents that can be present.

[0239] Compounds of the invention have at least one asymmetrical carbon atom and therefore all isomers, including enantiomers, stereoisomers, rotamers, tautomers and racemates of the compounds of Formulae (I-XI) (where they exist) are contemplated as being part of this invention. The invention includes d and I isomers in both pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional techniques, either by reacting optically pure or optically enriched starting materials or by separating isomers of a compound of the Formulae I-XI. Isomers may also include geometric isomers, e.g., when a double bond is present.

[0240] Those skilled in the art will appreciate that for some of the compounds of the Formulas I-XI, one isomer will show greater pharmacological activity than other isomers.

[0241] Compounds of the invention with an amino group can form pharmaceutically acceptable salts with organic and inorganic acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those in the art. The salt is prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt. The free base form may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium bicarbonate. The free base form differs from its respective salt form somewhat in certain physical properties, such as solubility in polar solvents, but the salt is otherwise equivalent to its respective free base forms for purposes of the invention.

[0242] Certain compounds of the invention are acidic (e.g., those compounds which possess a carboxyl group). These compounds form pharmaceutically acceptable salts with inorganic and organic bases. Examples of such salts are the sodium, potassium, calcium, aluminum, gold and silver salts. Also included are salts formed with pharmaceutically acceptable amines such as ammonia, alkyl amines, hydroxyalkylamines, N-methylglucamine and the like.

[0243] As used herein, “solvate” means a molecular or ionic complex of molecules or ions of solvent with those of solute (for example, one or more compounds of Formulae I-XI, isomers of the compounds of Formulae I-XI, or prodrugs of the compounds of Formulae I-XI). Non-limiting examples of useful solvents include polar, protic solvents such as water and/or alcohols (for example methanol).

[0244] As used herein, “prodrug” means' compounds that are drug precursors which, following administration to a patient, release the drug in vivo via some chemical or physiological process (e.g., a prodrug on being brought to the physiological pH or through enzyme action is converted to the desired drug form).

[0245] Preferred compounds of Formula (I) are those in which Ar is phenyl or R substituted phenyl, more preferably (4-R4)-substituted phenyl. Ar2 is preferably phenyl or R4-substituted phenyl, more preferably (4-R4)-substituted phenyl. Ar3 is preferably R5-substituted phenyl, more preferably (4-R5)-substituted phenyl. When Ar1 is (4-R4)-substituted phenyl, R4 is preferably a halogen. When Ar2 and Ar3 are R4- and R5-substituted phenyl, respectively, R4 is preferably halogen or —OR6 and R5 is preferably —OR6, wherein R6 is lower alkyl or hydrogen. Especially preferred are compounds wherein each of Ar1 and Ar2 is 4-fluorophenyl and Ar3 is 4-hydroxyphenyl or 4-methoxyphenyl.

[0246] X, Y and Z are each preferably —CH2—. R1 and R3 are each preferably hydrogen. R and R2 are preferably —OR6 herein R6 is hydrogen, or a group readily metabolizable to a hydroxyl (such as —O(CO)R6, —O(CO)OR9 and —O(CO)NR6R7, defined above).

[0247] The sum of m, n, p, q and r is preferably 2, 3 or 4, more preferably 3. Preferred are compounds wherein m, n and r are each zero, q is 1 and p is 2.

[0248] Also preferred are compounds of Formula (I) in which p, q and n are each zero, r is 1 and m is 2 or 3. More preferred are compounds wherein m, n and r are each zero, q is 1, p is 2, Z is —CH2— and R is —OR6, especially when R6 is hydrogen.

[0249] Also more preferred are compounds of Formula (I) wherein p, q and n are each zero, r is 1, m is 2, X is —CH2— and R2 is —OR6, especially when R6 is hydrogen.

[0401] For coadministration in separate tablets or capsules, representative formulations comprising a cholesterol absorption inhibitor such as are discussed above are well known in the art and representative formulations comprising an HM74 or HM74A agonist such as are discussed above are well known in the art. It is contemplated that where the two active ingredients are administered as a single composition, the dosage forms disclosed above for substituted azetidinone or β-lactam compounds may readily be modified using the knowledge of one skilled in the art.

[0402] The treatment compositions and therapeutic combinations of the present invention can inhibit the intestinal absorption of cholesterol in subjects, and can be useful in the treatment and/or prevention of vascular conditions, such as atherosclerosis, hypercholesterolemia and sitosterolemia, diabetes, obesity and lowering of plasma levels of cholesterol in subjects, in particular in mammals.

[0403] In another embodiment of the present invention, the compositions and therapeutic combinations of the present invention can inhibit sterol and/or 5α-stanol absorption or reduce plasma concentration of at least one sterol selected from the group consisting of phytosterols (such as sitosterol, campesterol, stigmasterol and avenosterol) and/or 5α-stanols (such as cholestanol, 5α-campestanol, 5α-sitostanol), cholesterol and mixtures thereof. The plasma concentration can be reduced by administering to a subject in need of such treatment an effective amount of at least one treatment composition or therapeutic combination comprising at least one HM74 or HM74A agonist and at least one sterol absorption inhibitor described above. The reduction in plasma concentration of sterols can range from about 1 to about 70 percent, and preferably about 10 to about 50 percent. Methods of measuring serum total blood cholesterol and total LDL cholesterol are well known to those skilled in the art and for example include those disclosed in PCT WO 99/38498 at page 11, incorporated by reference herein. Methods of determining levels of other sterols in serum are disclosed in H. Gylling et al., “Serum Sterols During Stanol Ester Feeding in a Mildly Hypercholesterolemic Population”, J. Lipid Res. 40: 593-600 (1999), incorporated by reference herein.

[0404] Illustrating the invention are the following examples which, however, are not to be considered as limiting the invention to their details. Unless otherwise indicated, all parts and percentages in the following examples, as well as throughout the specification, are by weight.

Example 1

[0405] Hypercholesterolemic Golden Syrian hamsters were used to evaluate the in vivo efficacy of a cholesterol absorption inhibitor compound of Formula (XII):

[0406] in combination with niacin. Compound XII can be prepared as shown in Example 9 of U.S. Pat. No. 5,688,787, which is incorporated by reference herein.

[0407] Hamsters were fed a cholesterol-containing diet for 7 days, which resulted in a 2-fold increase in plasma cholesterol and a 20-fold increase in hepatic cholesteryl esters. It was hypothesized that a compound which blocks dietary cholesterol absorption would reduce the accumulation of hepatic cholesteryl esters and inhibit the increase in plasma total cholesterol levels, while niacin should reduce plasma triglyceride levels.

[0408] Male Golden Syrian hamsters (Charles River Labs, Wilmington, Mass.) weighing between 100 and 125 g were fed Wayne rodent chow until study onset. At study onset (Day 1) animals were separated into groups (n=4-6/group) and fed chow supplemented with 0.5% by weight of cholesterol (Research Diets Inc., New Brunswick, N.J.). The Control and Test compounds were administered once daily for 7 days, starting on Day 1 via oral gavage in 0.2 ml corn oil. Corn oil was used as the Control. The Test compounds included the compound of Formula (XII) (3 mg/kg of body weight/day), niacin (100 mg/kg of body weight/day), or the compound of Formula (XII) combined with niacin as described in Table 1 below.

[0409] On Day 7, blood was collected into tubes containing ethylenediaminetetraacetic acid (EDTA), and plasma was prepared by low speed centrifugation at 4° C. Liver samples (0.5 g) were taken for neutral lipid analyses.

[0410] Nonfasted plasma cholesterol levels were determined by a modification of the cholesterol oxidase method, in which the reagents were available in a kit form from Wako Pure Chemicals Industries, Ltd. (Osaka, Japan). Ten μl of plasma was assayed for total cholesterol in 1 ml of 0.15 M tris buffer, pH 7.0 containing p-chlorophenol (0.1%), cholesterol oxidase (0.13 U/ml), cholesteryl ester hydrolase (0.13 U/ml), peroxidase (2.4 U/ml) and 4-aminoantipyrine (0.015%). Assays were carried out at 37° C. for 10 min, along with cholesterol standards (Sigma Chemical Co., St. Louis, Mo.) and the resultant red quinone pigment's absorbance was determined spectrophotometrically at 505 nm.

[0411] Plasma triglyceride levels were determined enzymatically by a modification of the lipase-glycerol phosphate oxidase method, obtained in a kit form from Sigma Chemical Co. Ten μl of plasma and glycerol standards were added to 1 ml of buffer, pH 7.0 containing ATP (0.3 mmol/1), Mg (3.0 mmol), 4-aminoantipyrine (0.15 mmol/1), Na N-ethyl-N-(3-sulfopropyl) n-anisidine (1.69 mmol/1), lipase (50,000 U/l), glycerol kinase (1000 U/l), glycerol phosphate oxidase (2000 U/1), and peroxidase (2000 U/l), incubated at 37° C. for 5 min., and the absorbance of the quinonemine dye was evaluated spectrophotometrically at 540 nm.

[0412] Samples of liver (0.5 g) were lipid extracted. Lipid extracts were dried under nitrogen into HPLC sample vials, resuspended in hexane and injected onto a Zorbax Sil (4.6×25 cm) silica column. Chromatography was performed using an isocratic mobile phase containing 98.8% hexane and 1.2% isopropanol at a flow rate of 2 ml/min. Lipids were detected by absorbance at 206 nm and quantitated by computer integration (System Gold, Beckman) of elution profiles. Elution time for cholesteryl ester was 1.45 min. Cholesteryl ester content of liver-derived samples was derived from a standard curve constructed using known amounts of cholesteryl oleate. Cholesteryl oleate was used as the standard since this is the major cholesteryl ester species present in the liver and this specific cholesteryl ester has an extinction coefficient that approximates that of a weighted average for all the cholesteryl esters present in the liver.

[0413] As shown in Table 1, Compound XII reduced plasma cholesterol levels and the accumulation of hepatic cholesteryl esters in the cholesterol-fed hamsters. Niacin reduced plasma triglyceride levels, but did not significantly reduce the cholesterol levels. The combination of Compound XII and niacin resulted in reductions in plasma and hepatic cholesterol levels, as well as plasma triglycerides (Table 1). These results indicate that the combination of the cholesterol absorption inhibitor of Compound XII and niacin can have additive effects on treating hyperlipidemia in male Golden Syrian hamsters, by reducing both cholesterol and triglyceride levels.
