Antagonists of MCP-1 function and methods of use thereof

Description

FIELD OF THE INVENTION

[0002] The present invention relates to compounds which are antagonists of MCP-1 function and are useful in the prevention or treatment of chronic or acute inflammatory or autoimmune diseases, especially those associated with aberrant lymphocyte or monocyte accumulation such as arthritis, asthma, atherosclerosis, diabetic nephropathy, inflammatory bowel disease, Crohn's disease, multiple sclerosis, nephritis, pancreatitis, pulmonary fibrosis, psoriasis, restenosis, and transplant rejection; and to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases.

BACKGROUND OF THE INVENTION

[0003] Chemokines: Structure and Function

[0004] The migration of leukocytes from blood vessels into diseased tissues is an important process in the initiation of normal inflammatory responses to certain stimuli or insults to the immune system. However, this process is also involved in the onset and progression of life-threatening inflammatory and autoimmune diseases; blocking leukocyte recruitment in these disease states, therefore, can be an effective therapeutic strategy.

[0005] The mechanism by which leukocytes leave the bloodstream and accumulate at inflammatory sites involves three distinct steps: (1) rolling, (2) arrest and firm adhesion, and (3) transendothelial migration [Springer, Nature 346:425-433 (1990); Lawrence and Springer, Cell 65:859-873 (1991); Butcher, Cell 67:1033-1036 (1991)]. The second step is mediated at the molecular level by chemoattractant receptors on the surface of leukocytes which bind chemoattractant cytokines secreted by proinflammatory cells at the site of damage or infection. Receptor binding activates leukocytes, increases their adhesiveness to the endothelium, and promotes their transmigration into the affected tissue, where they can secrete inflammatory and chemoattractant cytokines and degradative proteases that act on the subendothelial matrix, facilitating the migration of additional leukocytes to the site of injury.

[0006] The chemoattractant cytokines, collectively known as “chemokines,” are a large family of low molecular weight (8 to 10 kD) proteins that share the ability to stimulate directed cell migration (“chemotaxis”) [Schall, Cytokine 3:165-183 (1991); Murphy, Rev Immun 12:593-633 (1994)].

[0007] Chemokines are characterized by the presence of four conserved cysteine residues and are grouped into two main subfamilies based on whether the two amino-terminal cysteines are separated by one amino acid (CXC subfamily, also known as α-chemokines) or immediately adjacent to each other (CC subfamily, also referred to as β-chemokines) [Baggiolini et al., Adv Immunol 55:97-179 (1994); Baggiolini et al., Annu Rev Immunol 15:675-705 (1997); Deng et al., Nature 381:661-666 (1996); Luster, New Engl J Med 338:436445 (1998); Saunders and Tarby, Drug Discovery Today 4:80-92 (1999)].

[0008] The chemokines of the CXC subfamily, represented by IL-8, are produced by a wide range of cells and act predominantly on neutrophils as mediators of acute inflammation. The CC chemokines, which include MCP-1, RANTES, MIP-1α, and MIP-1β, are also produced by a variety of cells, but these molecules act mainly on monocytes and lymphocytes in chronic inflammation.

[0009] Like many cytokines and growth factors, chemokines utilize both high and low affinity interactions to elicit full biological activity. Studies performed with labeled ligands have identified chemokine binding sites (“receptors”) on the surface of neutrophils, monocytes, T cells, and eosinophils with affinities in the 500 pM to 10 nM range [Kelvin et al., J Leukoc Biol 54:604-612 (1993); Murphy, Annu Rev Immunol 12:593-633 (1994); Raport et al., J Leukoc Biol 59:18-23 (1996); Premack and Schall, Nature Med 2:1174-1178 (1996)]. The cloning of these receptors has revealed that cell surface high-affinity chemokine receptors belong to the seven transmembrane (“serpentine”) G-protein-coupled receptor (GPCR) superfamily.

[0010] Chemokine receptors are expressed on different cell types, including non-leukocyte cells. Some receptors are restricted to certain cells (e.g., the CXCR1 receptor is predominantly restricted to neutrophils), whereas others are more widely expressed (e.g., the CCR2 receptor is expressed on monocytes, T cells, natural killer cells, dendritic cells, and basophils).

[0011] Given that at least twice as many chemokines have been reported to date as there are receptors, there is a high degree of redundancy in the ligands and, not surprisingly, most chemokine receptors are rather promiscuous with regard to their binding partners. For example, both MIP-1α and RANTES bind to the CCR1 and CCR5 receptors, while IL-8 binds to the CXCR1 and CXCR2 receptors. Although most chemokines receptors bind more than one chemokine, CC receptors bind only CC chemokines, and CXC receptors bind only CXC chemokines. This ligand-receptor restriction may be related to the structural differences between CC and CXC chemokines, which have similar primary, secondary, and tertiary structures, but different quaternary structures [Lodi et al., Science 263:1762-1767 (1994)].

[0012] The binding of chemokines to their serpentine receptors is transduced into a variety of biochemical and physiological changes, including inhibition of cAMP synthesis, stimulation of cytosolic calcium influx, upregulation or activation of adhesion proteins, receptor desensitization and internalization, and cytoskeletal rearrangements leading to chemotaxis [Vaddi et al., J Immunol 153:4721-4732 (1994); Szabo et al., Eur J Immunol 27:1061-1068 (1997); Campbell et al., Science 279:381-384 (1998); Aragay et al., Proc Natl Acad Sci USA 95:2985-2990 (1998);

[0013] Franci et al., J Immunol 157:5606-5612 (1996); Aramori et al., EMBO J 16:4606-4616 (1997);

[0014] Haribabu et al., J Biol Chem 272:28726-28731 (1997); Newton et al., Methods Enzymol 287:174-186 (1997)]. In the case of macrophages and neutrophils, chemokine binding also triggers cellular activation, resulting in lysozomal enzyme release and generation of toxic products from the respiratory burst [Newton et al., Methods Enzymol 287:174-186 (1997); Zachariae et al., J Exp Med 171:2177-2182 (1990); Vaddi et al., J Leukocyte Biol 55:756-762 (1994)]. The molecular details of the chemokine-receptor interactions responsible for inducing signal transduction, as well as the specific pathways that link binding to the above-mentioned physiological changes, are still being elucidated. Notwithstanding the complexity of these events, it has been shown that in the case of the MCP-1/CCR2 interaction, specific molecular features of MCP-1 can induce different conformations in CCR2 that are coupled to separate post-receptor pathways [Jarnagin et al., Biochemistry 38:16167-16177 (1999)]. Thus, it should be possible to identify ligands that inhibit chemotaxis without affecting other signaling events.

[0015] In addition to their high-affinity seven transmembrane GPCRs, chemokines of both subfamilies bind to various extracellular matrix proteins such as the glycosaminoglycans (GAGs) heparin, chondroitin sulfate, heparan sulfate, and dermatan sulfate with affinities in the middle nanomolar to millimolar range. These low-affinity chemokine-GAG interactions are believed to be critical not only for conformational activation of the ligands and presentation to their high-affinity serpentine receptors, but also for the induction of stable chemokine gradients that may function to stimulate haptotaxis (i.e., the migration of specific cell subtypes in response to a ligand gradient that is affixed upon the surface of endothelial cells or embedded within the extracellular matrix) [Witt and Lander, Curr Biol 4:394-400 (1994); Rot, Eur J Immunol 23:303-306 (1993); Webb et al., Proc Natl Acad Sci USA 90:7158-7162 (1993); Tanaka et al, Nature 361:79-82 (1993); Gilat et al., J Immunol 153:4899-4906 (1994)]. Similar ligand-GAG interactions have been described for a variety of cytokines and growth factors, including the various members of the FGF family, hepatocyte growth factor, IL-3 and IL-7, GM-CSF, and VEGF [Roberts et al., Nature 332:376-378 (1988); Gilat et al., Immunol Today 17:16-20 (1996); Clarke et al., Cytokine 7:325-330 (1995); Miao et al., J Biol Chem 271:4879-4886 (1996); Vlodavsky et al., Cancer Metastasis Rev 15:177-186 (1996)].

[0016] MCP-1 and Diseases

[0017] Chemokines have been implicated as important mediators of allergic, inflammatory and autoimmune disorders and diseases, such as asthma, atherosclerosis, glomerulonephritis, pancreatitis, restenosis, rheumatoid arthritis, diabetic nephropathy, pulmonary fibrosis, and transplant rejection. Accordingly, it has been postulated that the use of antagonists of chemokine function may help reverse or halt the progression of these disorders and diseases.

[0018] In particular, elevated expression of MCP-1 has been observed in a number of chronic inflammatory diseases [Proost et al., Int J Clin Lab Res 26:211-223 (1996); Taub, D. D. Cytokine Growth Factor Rev 7:355-376 (1996)] including rheumatoid arthritis [Robinson et al., Clin Exp Immunol 101:398-407 (1995); Hosaka et al., ibid. 97:451-457 (1994); Koch et al., J Clin Invest 90:772-779 (1992); Villiger et al., J Immunol 149:722-727 (1992)], asthma [Hsieh et al., J Allergy Clin Immunol 98:580-587 (1996); Alam et al., Am J Respir Crit Care Med 153:1398-1404 (1996); Kurashima et al., J Leukocyte Biol 59:313-316 (1996); Sugiyarna et al., Eur Respir J 8:1084-1090 (1995)], and atherosclerosis [Yla-Herttuala et al., Proc Natl Acad Sci USA 88:5252-5256 (1991); Nelken et al., J Clin Invest 88:1121-1127 (1991)].

[0019] MCP- 1 appears to play a significant role during the early stages of allergic responses because of its ability to induce mast cell activation and LTC4 release into the airway, which directly induces AHR (airways hyper-responsiveness) [Campbell et al., J Immunol 163:2160-2167 (1999)].

[0020] MCP-1 has been found in the lungs of patients with idiopathic pulmonary fibrosis and is thought to be responsible for the influx of mononuclear phagocytes and the production of growth factors that stimulate mesenchymal cells and subsequent fibrosis [Antoniades et al., Proc Natl Acad Sci USA 89:5371-5375 (1992)]. In addition, MCP-1 is also involved in the accumulation of monocytes in pleural effusions, which is associated with both Mycobacterium tuberculosis infection and malignancy [Strieter et al., J Lab Clin Med 123:183-197 (1994)].

[0021] MCP-1 has also been shown to be constitutively expressed by synovial fibroblasts from rheumatoid arthritis patients, and its levels are higher in rheumatoid arthritis joints compared to normal joints or those from other arthritic diseases [Koch et al., J Clin Invest 90:772-779 (1992)]. These elevated levels of MCP-1 are probably responsible for the monocyte infiltration into the synovial tissue. Increased levels of synovial MIP-1α and RANTES have also been detected in patients with rheumatoid arthritis [Kundel et al., J Leukocyte Biol 59:6-12 (1996)].

[0022] MCP-1 also plays a critical role in the initiation and development of atherosclerotic lesions. MCP-1 is responsible for the recruitment of monocytes into atherosclerotic areas, as shown by immunohistochemistry of macrophage-rich arterial wall [Yla-Herttuala et al., Proc Natl Acad Sci USA 88:5252-5256 (1991); Nelken et al., J Clin Invest 88:1121-1127 (1991)] and anti-MCP-1 antibody detection [Takeya et al., Human Pathol 24:534-539 (1993)]. LDL-receptor/MCP-1-deficient and apoB-transgenic/MCP-1-deficient mice show significantly less lipid deposition and macrophage accumulation throughout their aortas compared with wild-type MCP-1 strains [Alcami et al., J Immunol 160:624-633 (1998); Gosling et al., J Clin Invest 103:773-778 (1999); Gu et al., Mol. Cell. 2:275-281 (1998); Boring et al., Nature 394:894-897 (1998).

[0023] Other inflammatory diseases marked by specific site elevations of MCP-1 include multiple sclerosis (MS), glomerulonephritis, and stroke.

[0024] These findings suggest that the discovery of compounds that block MCP-1 activity would be beneficial in treating inflammatory diseases.

[0025] Antagonists of Chemokine Function

[0026] Most chemokine antagonists reported to date are either neutralizing antibodies to specific chemokines or receptor-ligand antagonists, that is, agents that compete with specific chemokines for binding to their cognate serpentine receptors but, unlike the chemokines themselves, do not activate these receptors towards eliciting a functional response [Howard et al., Trend Biotechnol 14:46-51 (1996)].

[0027] The use of specific anti-chemokine antibodies has been shown to curtail inflammation in a number of animal models (e.g., anti-MIP-1α in bleomycin-induced pulmonary fibrosis [Smith et al., Leukocyte Biol 57:782-787 (1994)]; anti-IL-8 in reperfusion injury [Sekido et al., Nature 365:654-657 (1995)], and anti-MCP-1 in a rat model of glomerulonephritis [Wada et al., FASEB J 10:1418-1425 (1996)]). In the MRL-lpr mouse arthritis model, administration of an MCP-1 antagonist significantly reduced the overall histopathological score after the early onset of the disease [Gong et al., J Exp Med 186:131-137 (1997)].

[0028] A major problem associated with using antibodies to antagonize chemokine function is that they must be humanized before use in chronic human diseases. Furthermore, the ability of multiple chemokines to bind and activate a single receptor forces the development of a multiple antibody strategy or the use of cross-reactive antibodies in order to completely block or prevent pathological conditions.

[0029] Several small molecule antagonists of chemokine receptor function have been reported in the scientific and patent literature [White, J Biol Chem 273:10095-10098 (1998); Hesselgesser, J Biol Chem 273:15687-15692 (1998); Bright et al., BioorgMed Chem Lett 8:771-774 (1998); Lapierre, 26th Natl Med Chem Symposium, June 14-18, Richmond (Va.), USA (1998); Forbes et al., Bioorg Med Chem Lett 10:1803-18064 (2000); Kato et al., WO 97/24325; Shiota et al., WO 97/44329; Naya et al., WO 98/04554; Takeda Industries, JP 09-55572 (1998); Schwender et al., WO 98/02151; Hagmann et al., WO 98/27815; Connor et al., WO 98/06703; Wellington et al., U.S. Pat. No. 6,288,103].

[0030] The specificity of the chemokine receptor antagonists, however, suggests that inflammatory disorders characterized by multiple or redundant chemokine expression profiles will be relatively more refractory to treatment by these agents.

[0031] A different approach to target chemokine function would involve the use of compounds that disrupt the chemokine-GAG interaction. One class of such agents with potential therapeutic application would consist of small organic molecules that bind to the chemokine low affinity GAG-binding domain.

[0032] Compounds of this class might not inhibit binding of the chemokine to its high-affinity receptor per se, but would disrupt chemokine localization within the extracellular matrix and provide an effective block for directed leukocyte-taxis within tissues. An advantage of this strategy is the fact that most CC and CXC chemokines possess similar C-terminal protein folding domains that define the GAG-binding site, and, hence, such compounds would be more useful for the treatment of inflammatory disorders induced by multiple, functionally redundant chemokines [McFadden and Kelvin, Biochem Pharmacol 54:1271-1280 (1997)].

[0033] The use of small molecule drugs to bind cytokine ligands and disrupt interactions with extracellular GAGs has been reported with FGF-dependent angiogenesis [Folkman and Shing, Adv Exp Med Biol 313:355-364 (1992)]. For example, the heparinoids suramin and pentosan polysulphate both inhibit angiogenesis under conditions where heparin is either ineffective or even stimulatory [Wellstein and Czubayko, Breast Cancer Res Treat 38:109-119 (1996)]. In the case of suramin, the anti-angiogenic capacity of the drug has also been shown to be targeted against VEGF [Waltenberger et al., J Mol Cell Cardiol 28:1523-1529 (1996)] which, like FGF, possesses heparin-binding domains similar to those of the chemokines. Heparin or heparin sulphate has also been shown to directly compete for GAG interactions critical for T-cell adhesion mediated by MIP-1β in vitro [Tanaka et al., Nature 361:79-82 (1993)].

SUMMARY OF THE INVENTION

[0035] The present invention relates to compounds that inhibit MCP-1-induced chemotaxis of human monocytic cells both in vitro and in vivo. These novel MCP-1 antagonists are useful for the treatment of inflammatory diseases, especially those associated with lymphocyte and/or monocyte accumulation, such as atherosclerosis, diabetic nephropathy, inflammatory bowel disease, Crohn's disease, multiple sclerosis, nephritis, pancreatitis, pulmonary fibrosis, psoriasis, restenosis, rheumatoid arthritis, and other chronic or acute autoimmune disorders. In addition, these compounds can be used in the treatment of allergic hypersensitivity disorders, such as asthma and allergic rhinitis, characterized by basophil activation and eosinophil recruitment.

Such excipients may be solid, liquid, semisolid, or, in the case of an aerosol composition, gaseous.

[0104] “Pharmaceutically acceptable salts and esters” means any salt and ester=that is pharmaceutically acceptable and has the desired pharmacological properties. Such salts include salts that may be derived from an inorganic or organic acid, or an inorganic or organic base, including amino acids, which is not toxic or undesirable in any way. Suitable inorganic salts include those formed with the alkali metals, e.g., sodium and potassium, magnesium, calcium, and aluminum.

Pharmaceutically acceptable esters include esters formed from carboxy, sulfonyloxy, and phosphonoxy groups present in the compounds, e.g., Cl-6 alkyl esters. When there are two acidic groups present, a pharmaceutically acceptable salt or ester may be a mono-acid-mono-salt or ester or a di-salt or ester; and similarly, where there are more than two acidic groups present, some or all of such groups can be salified or esterified.

[0105] “Therapeutically effective amount” means that amount which, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease.

[0106] “Treating” or “treatment” of a disease in a mammal includes:

[0107] (1) Preventing the disease from occurring in a mammal which may be predisposed to the disease but does not yet experience or display symptoms of the disease;

[0108] (2) Inhibiting the disease, i.e., arresting its development, or

[0109] (3) Relieving the disease, i.e., causing regression of the disease.

[0110] “Disease” includes any unhealthy condition of an animal (which includes human and non-human mammals), including particularly various forms of inflammatory illnesses or diseases, such as asthmia, atherosclerosis, diabetic nephropathy, glomerulonepliritis, inflammatory bowel disease, Crohn's disease, multiple sclerosis, pancreatitis, pulmonary fibrosis, psoriasis, restenosis, rheumatoid arthritis, immune disorders, and transplant rejection.

[0111] The compounds of this invention may possess one or more chiral centers, and can therefore be produced as individual stereoisomers or as mixtures of stereoisomers, depending on whether individual stereo isomers or mixtures of stereoisomers of the starting materials are used. Unless indicated otherwise, the description or naming of a compound or groups of compounds is intended to include both the individual isomers or mixtures (racemic or otherwise) of stereoisomers. Methods for the determination of stereochemistry and the separation of stereoisomers are well known to a person of ordinary skill in the art [see the discussion in Chapter 4 of March J.: Advanced Organic Chemistry, 4th ed. John Wiley and Sons, New York, N.Y., 1992].

[0178] The above-listed preferences for the compounds of Formulae I, II, and III equally apply for the compounds of Formulae Ia, IIa and IIIa.

[0179] In addition, certain compounds of the invention may contain one or more chiral centers. In such cases, all stereoisomers also fall within the scope of this invention. The invention compounds include the individually isolated stereoisomers as well as mixtures of such stereoisomers.

[0180] Some of the compounds of Formula I, Formula II, and Formula III are capable of further forming pharmaceutically acceptable salts and esters. All of these forms are included within the scope of the present invention.

[0181] Pharmaceutically acceptable base addition salts of the compounds of Formula I, Formula II, and Formula III include salts which may be formed when acidic protons present in the parent compound are capable of reacting with inorganic or organic bases. Typically, the parent compound is treated with an excess of an alkaline reagent, such as hydroxide, carbonate or alkoxide, containing an appropriate cation. Cations such as Na+, K+, Ca2+ and NH4+ are examples of cations present in pharmaceutically acceptable salts. The Na+ salts are especially useful. Acceptable inorganic bases, therefore, include aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate and sodium hydroxide. Salts may also be prepared using organic bases, such as choline, dicyclohexylamine, ethylenediamine, ethanolamine, diethanolamine, triethanolamine, procaine, N-methylglucamine and the like [for a nonexclusive list see, for example, Berge et al., “Pharmaceutical Salts,” J. Pharma. Sci. 66:1 (1977)]. The free acid form may be regenerated by contacting the base addition salt with an acid and isolating the free acid in the conventional manner. The free acid forms can differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents.

[0182] Pharmaceutically acceptable acid addition salts of the compounds of Formula I, Formula II, and Formula III include salts which may be formed when the parent compound contains a basic group. Acid addition salts of the compounds are prepared in a suitable solvent from the parent compound and an excess of a non-toxic inorganic acid, such as hydrochloric acid, hydrobromic acid, sulfuric acid (giving the sulfate and bisulfate salts), nitric acid, phosphoric acid and the like, or a non-toxic organic acid such as acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, salicylic acid, p-toluenesulfonic acid, hexanoic acid, heptanoic acid, cyclopentanepropionic acid, lactic acid, o-(4-hydroxy-benzoyl)benzoic acid, 1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, camphorsulfonic acid, 4-methylbicyclo[2.2.2.]oct-2-ene-1 -carboxylic acid, glucoheptonic acid, gluconic acid, 4,4-methylenebis(3-hydroxy-2-naphthoic) acid, 3-phenylpropionic acid, trimethylacetic acid, tert-butylacetic acid, laurylsulfuric acid, glucuronic acid, glutamic acid, 3-hydroxy-2-naphthoic acid, stearic acid, muconic acid and the like. The free base form may be regenerated by contacting the acid addition salt with a base and isolating the free base in the conventional manner. The free base forms can differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents.

[0183] Also included in the embodiment of the present invention are salts of amino acids such as arginate and the like, gluconate, and galacturonate [see Berge, supra (1977)].

[0184] Some of the compounds of the invention may form inner salts or Zwitterions.

[0185] Certain of the compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms, and are intended to be encompassed within the scope of the present invention.

[0186] Certain of the compounds of the present invention may also exist in one or more solid or crystalline phases or polymorphs; the variable biological activities of such polymorphs or mixtures of such polymorphs are also included in the scope of this invention.

[0187] Some preferred compounds of the present invention are those listed in Table 11.

[0188] Pharmaceutical Compositions

[0189] A third embodiment of the present invention provides pharmaceutical compositions comprising a pharmaceutically acceptable excipient and a therapeutically effective amount of at least one compound of this invention.

[0190] Pharmaceutical compositions of the compounds of this invention, or derivatives thereof, may be formulated as solutions or lyophilized powders for parenteral administration. Powders may be reconstituted by addition of a suitable diluent or other pharmaceutically acceptable carrier prior to use. The liquid formulation is generally a buffered, isotonic, aqueous solution. Examples of suitable diluents are normal isotonic saline solution, 5% dextrose in water or buffered sodium or ammonium acetate solution. Such formulations are especially suitable for parenteral administration, but may also be used for oral administration. It may be desirable to add excipients such as polyvinylpyrrolidinone, gelatin, hydroxycellulose, acacia, polyethylene glycol, mannitol, sodium chloride or sodium citrate.

[0191] Alternatively, these compounds may be encapsulated, tableted or prepared in an emulsion or syrup for oral administration. Pharmaceutically acceptable solid or liquid carriers may be added to enhance or stabilize the composition, or to facilitate preparation of the composition. Liquid carriers include syrup, peanut oil, olive oil, glycerin, saline, alcohols and water. Solid carriers include starch, lactose, calcium sulfate, dihydrate, terra alba, magnesium stearate or stearic acid, talc, pectin, acacia, agar or gelatin. The carrier may also include a sustained release material such as glyceryl monostearate or glyceryl distearate, alone or with a wax. The amount of solid carrier varies but, preferably, will be between about 20 mg to about 1 g per dosage unit.

[0192] The pharmaceutical preparations are made following the conventional techniques of pharmacy involving milling, mixing, granulation, and compressing, when necessary, for tablet forms; or milling, mixing and filling for hard gelatin capsule forms. When a liquid carrier is used, the preparation will be in the form of a syrup, elixir, emulsion or an aqueous or non-aqueous suspension. Such a liquid formulation may be administered directly p.o. or filled into a soft gelatin capsule.

[0193] Some specific examples of suitable pharmaceutical compositions are described in the examples.

[0194] Typically, a pharmaceutical composition of the present invention is packaged in a container with a label indicating the use of the pharmaceutical composition in the treatment of a disease such as asthma, atherosclerosis, glomerulonephritis, pancreatitis, restenosis, rheumatoid arthritis, multiple sclerosis, diabetic nephropathy, pulmonary fibrosis, and transplant rejection, or a chronic or acute immune disorder, or a combination of any of these disease conditions.

[0195] Methods of Use

[0196] A fourth embodiment of the present invention provides a method for treating a disease treatable by administration of an MCP-1 inhibitor, for example, a chronic or acute inflammatory disease such as asthma, atherosclerosis, diabetic nephropathy, glomerulonephritis, inflammatory bowel disease, Crohn's disease, multiple sclerosis, pancreatitis, pulmonary fibrosis, psoriasis, restenosis, rheumatoid arthritis, or a chronic or acute immune disorder, or transplant rejection in a mammal in need thereof, comprising the administration to such mammal of a therapeutically effective amount of at least one compound of general Formula I, Formula II and Formula III or pharmaceutically acceptable salts and esters thereof.

[0197] The compounds of the present invention inhibit chemotaxis of a human monocytic cell line (THP-1 cells) induced by human MCP-1 in vitro. This inhibitory effect has also been observed in vivo. Indeed, the compounds have been shown to reduce monocyte infiltration in a thioglycollate-induced inflammation model in mice.

[0198] The compounds of the present invention have been found to prevent the onset or ameliorate symptoms in several animal models of inflammation. For example, the compounds inhibited recruitment of monocytes into the glomeruli in an anti-Thy-1 antibody-induced model of nephritis; reduced paw swelling in a rat model of adjuvant arthritis; inhibited neointimal hyperplasia after balloon injury in a rat model of restenosis, and reduced the amount of lesion of the aortic sinus in an apoE-deficient mouse model of atherosclerosis.

[0199] The ability of the compounds of this invention to block the migration of monocytes and prevent or ameliorate inflammation, which is demonstrated in the specific examples, indicates their usefulness in the treatment and management of disease states associated with aberrant leukocyte recruitment.

[0200] The use of the compounds of the invention for treating inflammatory and autoimmune disease by combination therapy may also comprise the administration of the compound of the invention to a mammal in combination with common anti-inflammatory drugs, cytokines, or immunomodulators.

[0201] The compounds of this invention are thus used to inhibit leukocyte migration in patients which require such treatment. The method of treatment comprises the administration, orally or parenterally, of an effective quantity of the chosen compound of the invention, preferably dispersed in a pharmaceutical carrier. Dosage units of the active ingredient are generally selected from the range of 0.01 to 1000 mg/kg, preferably 0.01 to 100 mg/kg, and more preferably 0.1 to 50 mg/kg, but the range will be readily determined by one skilled in the art depending on the route of administration, age, and condition of the patient. These dosage units may be administered one to ten times daily for acute or chronic disease. No unacceptable toxicological effects are expected when compounds of the invention are used in accordance with the present invention.

[0202] The invention compounds may be administered by any route suitable to the subject being treated and the nature of the subject's condition. Routes of administration include, but are not limited to, administration by injection, including intravenous, intraperitoneal, intramuscular, and subcutaneous injection, by transmucosal or transdermal delivery, through topical applications, nasal spray, suppository and the like, or may be administered orally. Formulations may optionally be liposomal formulations, emulsions, formulations designed to administer the drug across mucosal membranes or transdermal formulations. Suitable formulations for each of these methods of administration may be found in, for example, A. Gennaro, ed., Remington: The Science and Practice ofPharmacy, 20th ed., Lippincott, Williams & Wilkins, Philadelphia, Pa.

EXAMPLES

[0203] The following Examples serve to illustrate the preparation, properties, and therapeutic applications of the compounds of this invention. These Examples are not intended to limit the scope of this invention, but rather to show how to synthesize and use the compounds of this invention.

[0204] Preparation of the Compounds of the Invention: General Procedures

[0205] The following general procedures may be employed for the preparation of the compounds of the present invention.

[0206] The starting materials and reagents used in preparing these compounds are either available from commercial suppliers such as the Aldrich Chemical Company (Milwaukee, Wis.), Bachem (Torrance, Calif.), Sigrna (St. Louis, Mo.), or are prepared by methods well known to a person of ordinary skill in the art, following procedures described in such references as Fieser and Fieser's Reagents for Organic Synthesis, vols. 1-17, John Wiley and Sons, New York, N.Y., 1991; Rodd's Chemistry of Carbon Compounds, vols. 1-5 and supps., Elsevier Science Publishers, 1989; Organic Reactions, vols. 1-40, John Wiley and Sons, New York, N.Y., 1991; March J.: Advanced Organic Chemistry, 4th ed., John Wiley and Sons, New York, N.Y.; and Larock: Comprehensive Organic Transformations, VCH Publishers, New York, 1989.

[0207] In some cases, protective groups may be introduced and finally removed. For example, suitable protective groups for amino, hydroxy, and carboxy groups are described in Greene et al., Protective Groups in Organic Synthesis, 2nd ed., John Wiley and Sons, New York, 1991. Activation of carboxylic acids can be achieved by using a number of different reagents as described in Larock, Comprehensive Organic Transformations, VCH Publishers, New York, 1989.

[0209] Generally, a compound of Formula I, II, or III:

[0210] wherein X, Y, Z, and R1-R6 are as defined in the Summary of the Invention, may be prepared by a process comprisingsaid process comprising:

[0211] (a) contacting a compound of Formula Ib, IIb,, or IIIb

[0212] wherein X, Y, Z, and R1-R3 are as defined above,

[0214] where R6 is as defined above,

[0215] under appropriate conditions,

[0216] to produce a compound of Formula I, II, or III, wherein R4 and R5 are both H; or

[0217] (b) contacting a compound of Formula Ib, IIb or IIIb above with a haloformylation reagent and a compound of the formula

[0218] where R5 and R6 are as defined above,

[0219] under appropriate conditions,

[0220] to produce a compound of Formula I, II or III, wherein R4 is H; or

[0221] (c) elaborating substituents of a compound of Formula I, II or III in a manner known per se; or

[0222] (d) reacting the free base of a compound of Formula I, II or III with an acid to give a pharmaceutically acceptable addition salt; or

[0223] (e) reacting an acid addition salt of a compound of Formula I, II or III with a base to form the corresponding free base; or

[0224] (f) converting a salt of a compound of Formula I, II, or III to another pharmaceutically acceptable salt of a compound of Formula I, II, or III; or

[0225] (g) resolving a racemic mixture of any proportions of a compound of Formula I, II, or III to yield a stereoisomer thereof.

[0226] Step (a) may carried out in the presence of an organic solvent or a mixture of solvents at elevated temperatures, and the organic solvent may be toluene and the reaction may be carried out under refluxing conditions.

[0227] Step (b) may be carried out in an organic solvent or a mixture of solvents at elevated temperatures. The haloformylation reagent may be a compound of the formula A-(CO)—B wherein A and B are, independently, suitable leaving groups such as halogens, —COCl, —COBr and the like. The haloformylation reagent and organic solvent employed in step (b) may be oxalyl chloride and THF, respectively, and the reaction may be heated to above 50° C.

[0228] The compounds of the invention can be synthesized as shown in the following examples. These examples are merely illustrative of some methods by which the compounds of this invention can be synthesized, and various modifications to these examples can be made and will be suggested to a person of ordinary skill in the art having regard to this disclosure.

[0229] Compounds of the present invention may be prepared starting with a carboxamide and an isocyanate. Carboxamides and isocyanates starting materials may be purchased from various different commercial sources, such as, for example, the Aldrich Chemical Company, supra, or they may be prepared from standard procedures known in the art for preparing these compounds, such as the procedures described in the above cited references. The isocyanates may also be prepared according to the procedures described in the examples below. Typically, an aryl carboxamide is treated with an aryl isocyanate in an organic solvent or mixtures of suitable organic solvents. Preferably, the organic solvent is toluene. The carboxamide and the isocyanate may be combined as solutions or suspensions, depending on the solubilities of the compounds in the selected solvent. The carboxamide and the isocyanate may be added in a stoichiometric ratio (1:1), or a slight excess of the isocyanate may be used, for example between 1.01 fold and 2 fold excess, but typically about 1.01 to about 1.2 fold excess. Typically, the isocyanate is added to a suspension of the carboxamide in toluene, and the resulting mixture is heated until the reaction is determined to be complete. The reaction mixture may be heated at about 10° C. to about 150° C., preferably at about 40° C. to about 120° C. under an inert atmosphere such as nitrogen, or the reaction mixture may be maintained at the refluxing temperature of the mixture. The reaction may be allowed to proceed to completion in about 10 minutes to 24 hours. Preferably, the reaction is heated to reflux until the reaction is complete, over about 6 to 24 hours.

[0230] Upon cooling of the reaction mixture, the resulting product may be isolated by conventional techniques. Typically, the product is isolated by filtration. The precipitated solid may be filtered, washed with a solvent or a series of solvents, and isolated without further purification. Preferably, the precipitated product may be washed with a combination of toluene, methanol and then with ether, and the product may be dried under vacuum. If desired, the product may be further purified using conventional techniques, such as by recrystallization, chromatography, etc.

[0231] The compounds of the present invention may also be prepared from the condensation of an isocyanate with an amine. The isocyanate may be prepared from the corresponding carboxamide or may be obtained from commercial sources. Depending on the desired substitution of the amine, optionally, the amine may be substituted with an amine protecting group, such that the protecting group may be removed in a subsequent step if desired. In the first step of the process, a carboxamide in a suitable aprotic solvent is treated with a carbonylation reagent to form the corresponding isocyanate derivative. Typically, the aprotic solvent is dichloromethane, toluene, 2-methyltetrahydrofaran or THF, and them carbonylation reagent is oxalyl chloride. Preferably, the aprotic solvent is dichloromethane. Oxalyl chloride is preferably present in an excess, for example, between 1.1 to 3.0 equivalents, typically about 1.5 equivalents, over the carboxamide. The reaction is generally performed under an inert atmosphere where the mixture is heated to 50° C. to 175° C. for 15 minutes to 24 hours or until the reaction is deemed complete. Typically, the reaction is heated to reflux over 2 to 16 hours under nitrogen, and then cooled to room temperature. The solvent is removed in vacuo by distillation, and the resulting isocyanate is then condensed with a primary or secondary amine. Condensation with the amine may be performed by the addition of a solution of the amine in an aprotic solvent, such as THF, under an inert atmosphere, at a temperature between 0° C. and 20° C., preferably between 0° C. and 5° C. If the carbonylation and the subsequent condensation reaction are performed in the same solvent, the solvent removal step may be eliminated. Preferably, the reaction is performed at 0° C. to 5° C. for 1 to 24 hours, or until the reaction is complete. The solvent is removed by concentration under reduced pressure, and the product is isolated by conventional techniques such as filtration and washing of the crude product with a solvent followed by drying under vacuum, recrystallization, etc.

[0232] The preparation of the compounds of the present invention may also be performed by condensation of an amine or aniline derivative with a phosgene equivalent, followed by reaction of the resulting isocyanate with a carboxamide. Typically, a solution of an aniline or aniline derivative and triphosgene in tetrachloroethane or other suitable organic solvent is combined and stirred at 25° C. to 80° C. under an inert atmosphere for 2 to 12 hours or until the reaction is complete as determined by TLC or HPLC analysis of the reaction mixture. The solvent is removed under reduced pressure and the residue is dissolved in an aprotic solvent, such as toluene, and the resulting mixture is treated with a carboxamide. The mixture is heated to about 50° C. to 150° C., preferably from about 75° C. to 115° C. More preferably, the reaction mixture is heated to reflux for 2 to 24 hours or until the reaction is complete, and allowed to cool to room temperature. The precipitated solid is isolated by conventional techniques such as filtration. The filtered solid is then washed with a suitable solvent or mixtures of solvents. Typically, the solid is washed with toluene, methanol and then ether, and the washed product is dried in vacuo to give the product.

[0233] Cyclic acyl ureas of the present invention may be prepared according to methods known in the art. One method comprises the alkylation of the acyl urea nitrogens with an alkylating agent generically represented above as X—(CH2)2-4—Y, where X and Y are leaving groups, and may be the same or different. Leaving groups known in the art include halides, methanesulfonates, trifluoromethanesulfonates, p-toluenesulfonates, p-bromotoluenesulfonate, p-nitrobenzenesulfonates and the like. Representative alkylating agents include 1,2-dibromo-ethane, 1,3-dibromoethane, 1,3-dibromopropane, and the corresponding sulfonates and mixed halosulfonates. Typically, the acyl urea is treated with a base in an organic solvent or mixtures of solvents. Preferably, the base is an inorganic base such as sodium hydride, or an organic base such as dimethyl sulfoxide and sodium hydride. Preferably, the solvent is a polar, aprotic solvent such as tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, glycols, or mixtures of such solvents. Typically, a solution or suspension of the acyl urea is slowly added to the base in an organic solvent at about 0° C. to about 25° C., and the resulting mixture is stirred for about 10 minutes to about 5 hours, preferably about 30 minutes. The alkylating agent is added and the mixture is stirred until the reaction is deemed complete. Alkylation of both urea nitrogens may be accomplished in a single step, or may be accomplished sequentially in a two step procedure be exposing the partially alkylated product with the same or different base. The reaction is then quenched with a solvent, preferably water, and the mixture is extracted multiple times with an organic solvent. Preferably, the extracting solvent is dichloromethane. The combined organic extracts are washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to afford the product, which may be purified using standard conditions known in the art. Purification may be performed by silica gel chromatography in a mixture of organic solvents, such as ethyl acetate and petroleum ether.

Inhibition of MCP-1 Induced Chemotaxis

[0261] A 96 well microchemotaxis chamber with a 5 μm-pore size, PVP-coated polycarbonate filter membrane (Neuro Probe Inc., Cabin John, Md.) was used for testing. Compounds were prepared as 10 mM stock solution in DMSO. THP-1 cells (2×106 cells/mL) were labeled with 5 μM Calcein AM containing 0.1% F127 (Molecular Probe, Eugene, Oreg.) at 37° C. for 30 min, and then pretreated with compound at room temperature for an additional 30 min. The lower chamber was loaded with medium containing 12.5 nM hMCP-1. The filter membrane was placed over the lower chamber, followed by a silicon gasket and the upper chamber. The pretreated THP-1 cells (4×105 cells/50 μL of RPMI1640 medium per well) were added to the upper chamber and incubated in 5% CO2 at 37° C. for 2 hr. The migrated cells were determined with a fluorescent plate reader (LJL BioSystems, Sunnyvale, Calif.). Table 12 shows the IC50 (concentration of compound that inhibited migration of 50% of the cells relative to control) for several compounds of the present invention.

Apolipoprotein E-Deficient Mouse Model

[0263] Apolipoprotein E (apoE) is a component of several plasma lipoproteins, including chylomicrons, VLDL, and HDL. Receptor-mediated catabolism of these lipoprotein particles is mediated through the interaction of apoE with the LDL receptor (LDLR) or with LDLR-related protein (LRP). ApoE-deficient mice exhibit hypercholesterolemia and develop complex atheromatous lesions similar to those seen in humans. The efficacy of the compounds of the present invention was also evaluated using this animal model.

[0264] Male, 4 week-old apoE-deficient mice were fed on high-fat diet (15% fat, 1.25% cholesterol). The test compound was administered as food admixture for 8 weeks. At 12 weeks old, the mice were fasted for 4 hours and then sacrificed under ether anesthesia. Blood was collected in the presence of heparin, and the hearts were perfused in situ with PBS (pH 7.4), followed by 4% paraformaldehyde for 5 min.

[0265] To determine cross-sectional lesion areas, the hearts were embedded in OCT compound and sectioned at 10 μm using cryostat. The sections were stained with oil red O. Each section of the aortic valve was evaluated for oil red O staining by capturing images directly from a RGB camera attached to a light microscope; image analysis was performed with the IPAP-WIN software (Sumika Tekno, Japan). Five sections were examined for each animal, and the sum of the lesion areas was calculated and expressed as the percent of the total cross-sectional wall area. Total cholesterol was determined with a Determiner assay kit (Kyowa Medex, Japan).

[0266] The effect of a representative test compound in this animal model of atherosclerosis is shown in Table 14.
