WO 2010/068663 PCT/US2009/067307 4-AZETIDINYL-1-HETEROARYL-CYCLOHEXANOL ANTAGONISTS OF CCR2 CROSS-REFERENCE TO RELATED APPLICATIONS 5 This application claims priority from United States Provisional Applications Serial Nos. 61/121,272 filed December 10, 2008 and 61/167,295 filed April 7, 2009, the contents of each of which are hereby incorporated by reference in their entirety. FIELD OF THE INVENTION 10 The invention is directed to substituted dipiperidine compounds, which are antagonists to the chemoattractant cytokine receptor 2 (CCR2), pharmaceutical compositions, and methods for use thereof. More particularly, the CCR2 antagonists are substituted piperidyl acrylamide compounds useful for preventing, treating or ameliorating a CCR2 mediated syndrome, disorder or disease. 15 BACKGROUND OF THE INVENTION CCR2 is a member of the GPCR family of receptors, as are all known chemokine receptors, and are expressed by monocytes and memory T-lymphocytes. The CCR2 signaling cascade involves activation of phospholipases (PLC 2), protein kinases (PKC), 20 and lipid kinases (PI-3 kinase). Chemoattractant cytokines (i.e., chemokines) are relatively small proteins (8-10 kD), which stimulate the migration of cells. The chemokine family is divided into four subfamilies based on the number of amino acid residues between the first and second highly conserved cysteines. 25 Monocyte chemotactic protein-I (MCP-1) is a member of the CC chemokine subfamily (wherein CC represents the subfamily having adjacent first and second cysteines) and binds to the cell-surface chemokine receptor 2 (CCR2). MCP-1 is a potent chemotactic factor, which, after binding to CCR2, mediates monocyte and lymphocyte migration (i.e., chemotaxis) toward a site of inflammation. MCP-1 is also expressed by 30 cardiac muscle cells, blood vessel endothelial cells, fibroblasts, chondrocytes, smooth muscle cells, mesangial cells, alveolar cells, T-lymphocytes, marcophages, and the like. 1 WO 2010/068663 PCT/US2009/067307 After monocytes enter the inflammatory tissue and differentiate into macrophages, monocyte differentiation provides a secondary source of several proinflammatory modulators, including tumor necrosis factor-a (TNF-a), interleukin-1 (IL-1), IL-8 (a member of the CXC chemokine subfamily, wherein CXC represents one 5 amino acid residue between the first and second cysteines), IL-12, arachidonic acid metabolites (e.g., PGE 2 and LTB 4 ), oxygen-derived free radicals, matrix metalloproteinases, and complement components. Animal model studies of chronic inflammatory diseases have demonstrated that inhibition of binding between MCP-1 and CCR2 by an antagonist suppresses the 10 inflammatory response. The interaction between MCP-1 and CCR2 has been implicated (see Rollins B J, Monocyte chemoattractant protein 1: a potential regulator of monocyte recruitment in inflammatory disease, Mol. Med. Today, 1996, 2:198; and Dawson J, et al., Targeting monocyte chemoattractant protein-I signaling in disease, Expert Opin. Ther. Targets, 2003 Feb. 7 (1):35-48) in inflammatory disease pathologies such as psoriasis, 15 uveitis, atherosclerosis, rheumatoid arthritis (RA), multiple sclerosis, Crohn's Disease, nephritis, organ allograft rejection, fibroid lung, renal insufficiency, type II diabetes and diabetic complications, diabetic nephropathy, diabetic retinopathy, diabetic retinitis, diabetic microangiopathy, tuberculosis, sarcoidosis, invasive staphylococcia, inflammation after cataract surgery, allergic rhinitis, allergic conjunctivitis, chronic 20 urticaria, Chronic Obstructive Pulmonary Disease (COPD), allergic asthma, periodontal diseases, periodonitis, gingivitis, gum disease, diastolic cardiomyopathies, cardiac infarction, myocarditis, chronic heart failure, angiostenosis, restenosis, reperfusion disorders, glomerulonephritis, solid tumors and cancers, chronic lymphocytic leukemia, chronic myelocytic leukemia, multiple myeloma, malignant myeloma, Hodgkin's disease, 25 and carcinomas of the bladder, breast, cervix, colon, lung, prostate, and stomach. Monocyte migration is inhibited by MCP-1 antagonists (either antibodies or soluble, inactive fragments of MCP-1), which have been shown to inhibit the development of arthritis, asthma, and uveitis. Both MCP-I and CCR2 knockout (KO) mice have demonstrated that monocyte infiltration into inflammatory lesions is significantly 30 decreased. In addition, such KO mice are resistant to the development of experimental allergic encephalomyelitis (EAE, a model of human MS), cockroach allergen-induced 2 WO 2010/068663 PCT/US2009/067307 asthma, atherosclerosis, and uveitis. Rheumatoid arthritis and Crohn's Disease patients have improved during treatment with TNF-a antagonists (e.g., monoclonal antibodies and soluble receptors) at dose levels correlated with decreases in MCP-1 expression and the number of infiltrating macrophages. 5 MCP-1 has been implicated in the pathogenesis of seasonal and chronic allergic rhinitis, having been found in the nasal mucosa of most patients with dust mite allergies. MCP-1 has also been found to induce histamine release from basophils in vitro. During allergic conditions, both allergens and histamines have been shown to trigger (i.e. , to up regulate) the expression of MCP-1 and other chemokines in the nasal mucosa of people 10 with allergic rhinitis, suggesting the presence of a positive feedback loop in such patients. There remains a need for small molecule CCR2 antagonists for preventing, treating or ameliorating a CCR2 mediated inflammatory syndrome, disorder or disease resulting from MCP- 1 induced monocyte and lymphocyte migration to a site of inflammation. 15 All documents cited herein are incorporated by reference.

Methods of Use The present invention is directed to a method for preventing, treating or ameliorating a CCR2 mediated syndrome, disorder or disease comprising administering 20 to a subject in need thereof an effective amount of a compound of Formula (I) or a form, composition or medicament thereof. Examples of a CCR2 mediated syndrome, disorder or disease for which the compounds of Formula (I) are useful include chronic obstructive pulmonary disorder (COPD), ophthalmic disorders, uveitis, atherosclerosis, rheumatoid arthritis, psoriasis, 25 psoriatic arthritis, atopic dermatitis, multiple sclerosis, Crohn's Disease, ulcerative colitis, nephritis, organ allograft rejection, fibroid lung, renal insufficiency, type-I diabetes, type II diabetes, diabetic complications, diabetic nephropathy, diabetic retinopathy, diabetic retinitis, diabetic microangiopathy, overweight, obesity, obesity-associated insulin resistance, metabolic syndrome, tuberculosis, chronic obstructive pulmonary disease, 30 sarcoidosis, invasive staphyloccocia, inflammation after cataract surgery, allergic rhinitis, allergic conjunctivitis, chronic urticaria, asthma, allergic asthma, periodontal diseases, 44 WO 2010/068663 PCT/US2009/067307 periodonitis, gingivitis, gum disease, diastolic cardiomyopathies, cardiac infarction, myocarditis, chronic heart failure, angiostenosis, restenosis, reperfusion disorders, aortic abdominal aneurism, multiple sclerosis, glomerulonephritis, solid tumors and cancers, chronic lymphocytic leukemia, chronic myelocytic leukemia, multiple myeloma, 5 malignant myeloma, Hodgkin's disease, carcinomas of the bladder, breast, cervix, colon, lung, prostate, or stomach, and chronic neuroinflammatory disorders including, but not limited to, Alzheimer's disease, ischemic stroke, spinal cord injury, nerve crush injury and traumatic brain injury. The term "administering" with respect to the methods of the invention, means a 10 method for therapeutically or prophylactically preventing, treating or ameliorating a syndrome, disorder or disease as described herein by using a compound of Formula (I) or a form, composition or medicament thereof. Such methods include administering an effective amount of said compound, compound form, composition or medicament at different times during the course of a therapy or concurrently in a combination form. The 15 methods of the invention are to be understood as embracing all known therapeutic treatment regimens. The term "subject" refers to a patient, which may be animal, typically a mammal, typically a human, which has been the object of treatment, observation or experiment. In one aspect of the invention, the subject is at risk of (or susceptible to) developing a 20 syndrome, disorder or disease that is associated with elevated MCP-1 expression or MCP-1 overexpression, or a patient with an inflammatory condition that accompanies syndromes, disorders or diseases associated with elevated MCP- 1 expression or MCP- 1 overexpression. The term "therapeutically effective amount" means that amount of active 25 compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue system, animal or human, that is being sought by a researcher, veterinarian, medical doctor, or other clinician, which includes preventing, treating or ameliorating the symptoms of a syndrome, disorder or disease being treated. The term "uveitis" generically refers to any inflammatory disease involving the 30 eye. Uveitis can be divided into clinically distinct subtypes based on the part of the eye in which the inflammation is present (percentages correspond to patients known to fit these 45 WO 2010/068663 PCT/US2009/067307 categories): anterior (51%), intermediate (13%), posterior (20%), or panuveitis (16%) and, according to the course of the disease, as either acute (16%), recurring (26%), or chronic (5 8%). Those with anterior uveitis (-19%) eventually develop irreparable vision damage despite aggressive treatment such as unilateral blindness (9%), bilateral blindness 5 (2%), or unilateral or bilateral vision impairment (8%). Most cases of uveitis are idiopathic, but known causes include infection (e.g., toxoplasmosis, cytomegalovirus, and the like) or development as a component of a systemic inflammatory and/or autoimmune disorder (e.g., juvenile RA, HLA-B27 associated spondyloarthropathies, sarcoidosis, and the like). (HLA-B27: Human Leukocyte Antigen B*27- is a class I surface antigen 10 encoded by the B locus in the major histocompatibility complex (MHC) on chromosome 6 and presents micobial antigens to T cells. HLA-B27 is strongly associated with a certain set of autoimmune diseases referred to as the seronegative spondyloarthropathies.) When employed as CCR2 inhibitors, the compounds of the invention may be administered in an effective amount within the dosage range of about 0.5 mg to about 10 15 g, preferably between about 0.5 mg to about 5 g, in single or divided daily doses. The dosage administered will be affected by factors such as the route of administration, the health, weight and age of the recipient, the frequency of the treatment and the presence of concurrent and unrelated treatments. It is also apparent to one skilled in the art that the therapeutically effective dose 20 for compounds of the present invention or a pharmaceutical composition thereof will vary according to the desired effect. Therefore, optimal dosages to be administered may be readily determined by one skilled in the art and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease condition. In addition, factors associated with the particular subject being 25 treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to an appropriate therapeutic level. The above dosages are thus exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention. The compounds of Formula (I) and/or (Ia) may be formulated into pharmaceutical 30 compositions comprising any known pharmaceutically acceptable carriers. Exemplary carriers include, but are not limited to, any suitable solvents, dispersion media, coatings, 46 WO 2010/068663 PCT/US2009/067307 antibacterial and antifungal agents and isotonic agents. Exemplary excipients that may also be components of the formulation include fillers, binders, disintegrating agents and lubricants. The pharmaceutically-acceptable salts of the compounds of Formula (I) and/or 5 (Ia) include the conventional non-toxic salts or the quaternary ammonium salts which are formed from inorganic or organic acids or bases. Examples of such acid addition salts include acetate, adipate, benzoate, benzenesulfonate, citrate, camphorate, dodecylsulfate, hydrochloride, hydrobromide, lactate, maleate, methanesulfonate, nitrate, oxalate, pivalate, propionate, succinate, sulfate and tartrate. Base salts include ammonium salts, 10 alkali metal salts such as sodium and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases such as dicyclohexylamino salts and salts with amino acids such as arginine. Also, the basic nitrogen-containing groups may be quaternized with, for example, alkyl halides. The pharmaceutical compositions of the invention may be administered by any 15 means that accomplish their intended purpose. Examples include administration by parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, transdermal, buccal or ocular routes. Alternatively or concurrently, administration may be by the oral route. Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, for example, water-soluble salts, acidic 20 solutions, alkaline solutions, dextrose-water solutions, isotonic carbohydrate solutions and cyclodextrin inclusion complexes. The present invention also encompasses a method of making a pharmaceutical composition comprising mixing a pharmaceutically acceptable carrier with any of the compounds of the present invention. Additionally, the present invention includes 25 pharmaceutical compositions made by mixing a pharmaceutically acceptable carrier with any of the compounds of the present invention. As used herein, the term "composition" is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combinations of the specified ingredients in the specified amounts. 30 47 WO 2010/068663 PCT/US2009/067307 Polymorphs and Solvates Furthermore, the compounds of the present invention may have one or more polymorph or amorphous crystalline forms and as such are intended to be included in the scope of the invention. In addition, the compounds may form solvates, for example with 5 water (i.e., hydrates) or common organic solvents. As used herein, the term "solvate" means a physical association of the compounds of the present invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in 10 the crystal lattice of the crystalline solid. The term "solvate" is intended to encompass both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like. It is intended that the present invention include within its scope polymorphs and solvates of the compounds of the present invention. Thus, in the methods of treatment of 15 the present invention, the term "administering" shall encompass the means for treating, ameliorating or preventing a syndrome, disorder or disease described herein with the compounds of the present invention or a polymorph or solvate thereof, which would obviously be included within the scope of the invention albeit not specifically disclosed. In another embodiment, the invention relates to a compound as described in the 20 Examples or Formula (I) or Formula (Ta) for use as a medicament, in particular, for use as a medicament for treating a CCR2 mediated syndrome disorder or disease. In another embodiment, the invention relates to the use of a compound as described in the Examples of Formula (I) or Formula (Ta) for the preparation of a medicament for the treatment of a disease associated with an elevated or inappropriate 25 CCR2 activity. The present invention includes within its scope prodrugs of the compounds of this invention. In general, such prodrugs will be functional derivatives of the compounds which are readily convertible in vivo into the required compound. Thus, in the methods of treatment of the present invention, the term "administering" shall encompass the 30 treatment of the various disorders described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the 48 WO 2010/068663 PCT/US2009/067307 specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in "Design of Prodrugs", Ed. H. Bundgaard, Elsevier, 1985. Where the compounds according to this invention have at least one chiral center, 5 they may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as diastereomers. It is to be understood that all such isomers and mixtures thereof are encompassed within the scope of the present invention. Where the processes for the preparation of the compounds according to the 10 invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation 15 of diastereomeric pairs by salt formation with an optically active acid, such as (-)-di-p toluoyl-D-tartaric acid and/or (+)-di-p-toluoyl-L-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using 20 a chiral HPLC column. During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemisty, 25 ed. J.F.W. McOmie, Plenum Press, 1973; and T.W. Greene & P.G.M.

The tissue was opened along the mesenteric border, pinned flat and the mucosa removed. The remaining muscle layer was 5 fixed briefly in 100% EtOH and then stained using Hanker-Yates reagent to detect myeloperoxidase-containing immune cells. At 10 mpk, P.O. bid, a compound is deemed efficacious if the inhibition of cell migration reaches 30% compared with vehicle-treated animals. The compound of Example 40 was found to be efficacious in blocking cell migration. 10 Example 77: Thiolycollate-Induced Peritonitis in Mice. Animals were orally dosed with vehicle or CCR2 antagonists at 3, 10, 30 and 100 mg/kg bid). One hour later, the animals were intraperiponeally injected with sterile thioglycollate (25 mL/kg, ip, Sigma) for induction of peritonitis. Animals were orally 15 treated twice daily with vehicle or CCR2 antagonists. At 72-hour time point, perinoteal cavities were lavaged with 10 mL of sterile saline. Total cell counts in the peritoneal lavage fluid were performed using a microscope and cell differentiation was performed using cytospin analysis after Giemsa staining (Hema Tek 2000). Percent inhibition of the thioglycollate-induced peritonitis was calculated by comparing the change in number of 20 leukocytes of CCR2 antagonist treated mice to the vehicle-treated mice. At 10 mpk, p.o. bid, the compound of Example 40 was shown to have >50% inhibition of thioglycollate induced peritonitis. Example 78: MCP-1-Induced Monocyte Recruitment to Airway of Mice. 25 Animals were orally treated with vehicle or CCR2 antagonists at 3, 10, and 30 mg/kg po bid). One hour later, the animals were intranasally dosed with 4 tg of MCP-1 in sterile saline. The animals were orally treated twice daily with vehicle or CCR2 antagonists. After 48 h, mice were euthanized by intraperitoneal injection of anesthesia solution (Sleepaway-Sodium pentobarbital). Whole bronchoalveolar lavage (BAL) was performed 30 using 1.4 ml of ice-cold PBS containing 3 mM EDTA. Total cell counts in the BAL lavage fluid were performed using a microscope and cell differentiation was performed 153 WO 2010/068663 PCT/US2009/067307 using cytospin analysis after Giemsa staining (Hema Tek 2000). Percent inhibition was calculated by comparing the change in number of total leukocyte counts (including monocytes/macrophages and lymphocytes) of compound-treated mice to the vehicle treated mice. Compounds are deemed efficacious if percent inhibition reaches 30%. At 5 10 mpk, p.o. bid, the compound of Example 40 was shown to have >50% inhibition. Example 79: High-fat Diet Induced Obesity and Insulin Resistance in Mice. Obesity was induced by a high-fat diet that derived approximately 60% calories from lipids (D-12492; Research Diets Inc.) in animals for 10- 24 weeks at age of 7 weeks. 10 Prior to age 7 weeks, animals were fed a standard pellet diet, in which 5% of calories were provided as fat. Obese animals were randomized by body weight and fat mass. The obese animals were orally treated with vehicle or CCR2 antagonists at 3, 10 and 30 mg/kg, po bid. Body weight and food intake and fasting blood glucose levels were monitored. Body mass was determined by a NMR analyzer (Burker MiniSpec). Insulin 15 tolerance test was carried out in animals that were fasted for 3 hours. After an intraperitoneal bolus injection of recombinant human insulin (1.5 U/kg), blood glucose concentrations were measured using a Glucometer before and 15, 30, 45, 60, 90 and 120 minutes after injection. Glucose tolerance tests were performed after an overnight (17 hour) fast. Blood glucose concentrations were measured before and after 15, 30, 60, 90, 20 120 minutes after an oral dose of glucose dissolved in water (lg/kg). Energy expenditure analysis was monitored by a complete laboratory animal monitor system. After 40 days treatment with vehicle or CCR2 antagonists, the animals were sacrificed by CO 2 asphyxiation. Percent of weight loss was calculated by comparing the body weight changes of the compound-treated mice with the vehicle-treated mice. At 10 mpk, p.o. 25 bid, the compound of Example 40 was shown to reduce body weight >8%. Example 80: Mouse Model of Allergic Asthma. Animals were sensitized by intraperitoneal injection of 10 tg chicken egg albumin (OVA) absorbed to 1 mg Imject* in 100 tL phosphate-buffered saline (PBS) on days 0 30 and 5. Control animals received PBS ip. OVA-immunized animals were challenged by inhalation of 0.50% OVA aerosol for 10 minutes by an ultrasonic nebulizer on days 12, 16 154 WO 2010/068663 PCT/US2009/067307 and 20. Control animals were challenged with PBS in similar fashion. The OVA sensitized animals received vehicle (0.5% Methocel) or CCR2 antagonists orally at 3, 10, 30 mg/kg twice daily from days 9-20 and once daily on day 21, 2 hours before sacrifice. Dexamethason (5 mg/kg) and Montelukast (1 mg/kg) were given orally once a day. On 5 day 21, 2 hours post the last dose of CCR2 compounds, bronchial reactivity to aerosolized methacholine was measured using a Buxco whole body plethysmograpgh. On day 21, the animals were sacrificed. Bronchoalveolar lavage fluid was collected (1 mL) and total cells counted. The numbers of eosinophils, lymphocytes, monocytes and neutrophils were determined using cytospin analysis after Giemsa staining (Hema Tek 10 2000). Percent inhibition of total BAL leukocyte count (and eosinophil count) was calculated by comparing the compound-treated mice with vehicle-treated mice. Compounds are deemed efficacious if the inhibition reaches 30%. At 10 mpk, p.o. bid, the compound of Example 40 was shown to be efficacious in reduction of cell count. 15 While the foregoing specification teaches the principles of the present invention, with examples provided for the purpose of illustration, it will be understood that the practice of the invention encompasses all of the usual variations, adaptations and/or modifications as come within the scope of the following claims and their equivalents. 20 155
