WO 2007/121432 PCT/US2007/066772 1 TITLE OF THE INVENTION BENZOAZEPIN-OXY-ACETIC ACID DERIVATIVES AS PPAR-DELTA AGONISTS USED FOR THE INCREASE OF HDL-C, LOWER LDL-C AND LOWER CHOLESTEROL CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U. S. Provisional Application 60/793,001, filed on April 18, 2006, which is incorporated by reference herein in its entirety. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT The research and development of the invention described below was not federally sponsored. BACKGROUND OF THE INVENTION The peroxisome proliferator-activated receptors (PPARs) are considered to be metabolic sensors regulating the expression of genes involved in glucose and lipid homeostasis. They are members of nuclear receptor superfamily of RXR heterodimers and are ligand-activated transcription factors. Agonists of the PPARa (e.g., Gemfibrozil) and PPARy (e.g., Avandia@) subtypes are used for the treatment of dyslipidemias and diabetes, respectively. Each receptor has a distinct tissue distribution with PPARa showing highest expression in liver, PPAR in adipose tissue and PPARS having the widest distribution being ubiquitously expressed in adult rat (Braissant et al., 1996) and in humans, expression was found in many different tissues involved in lipid metabolism including liver, kidney, abdominal adipose and skeletal muscle (Auboeuf et al., 1997).
WO 2007/121432 PCT/US2007/066772 2 Recently, potent ligands for PPARS have been published allowing a better understanding of its function in lipid metabolism (Barak et al, 2002; Oliver et al., 2001; Tanaka et al, 2003; Wang et al., 2003). The main effect of these compounds in db/db mice (Leibowitz et al., 2000) and obese rhesus monkeys (Oliver et al., 2001) was an increase of high density lipoprotein cholesterol (HDL-C) and a decrease in triglycerides with little effect on glucose (although insulin levels were decreased in monkeys). HDL-C serves to remove cholesterol from peripheral cells through a process called reverse cholesterol transport. The first and rate-limiting step, which is a transfer of cellular cholesterol and phospholipids to the apolipoprotein A-1 component of HDL, is mediated by the ATP binding cassette transporter Al (ABCAl) (Lawn et al., 1999). PPARb activation appears to increase HDL-C through transcriptional regulation of ABCA1 (Oliver et al., 2001). Therefore, by inducing ABCA1 mRNA in macrophages, PPAR8 agonists could increase HDL-C levels in patients and remove excess cholesterol from lipid-laden macrophages, one of the major players in atherosclerotic lesion development. This would be an alternative therapy to the statin drugs, which show little effect on HDL-C and mainly decrease LDL-C or the fibrates, the only marketed PPARa agonists, having low potency and inducing only modest HDL-C elevations. In addition, like the fibrates, PPARS agonists have the potential to also reduce triglycerides, an additional risk factor for cardiovascular disease. Examples of known PPAR delta agonists variously useful for hyperlipidemia, diabetes, or atherosclerosis include L-165041 (Leibowitz et al., 2000) and GW501516 (Oliver et al., 2001). There is a continuing need for new PPAR delta agonists. There is a further need for new PPAR delta agonists that increase HDL-C, lower LDL-C, and/or lower cholesterol. There is a further need for new PPAR delta agonists for the treatment of diabetes, nephropathy, neuropathy, retinopathy, polycystic ovary syndrome, WO 2007/121432 PCT/US2007/066772 3 hypertension, ischemia, stroke, irritable bowel disorder, inflammation, cataract, cardiovascular diseases, Metabolic X Syndrome, hyper-LDL cholesterolemia, dyslipidemia (including hypertriglyceridemia, hypercholesterolemia, mixed hyperlipidemia, and hypo-HDL cholesterolemia), atherosclerosis, obesity, and other disorders related to lipid metabolism and energy homeostasis complications thereof.

The compounds of the present invention may also be present in the form of pharmaceutically acceptable salts. For use in medicine, the salts of the compounds of this invention refer to non-toxic "pharmaceutically acceptable salts" (Ref. International J. Pharm., 1986, 33,201-217; J. Pharm.Sci., 1997 (Jan), 66, 1, 1). Other salts well known to those in the art may, however, be useful in the preparation of compounds according to this invention or of their pharmaceutically acceptable salts. Representative organic or inorganic acids include, but are not limited to, hydrochloric, hydrobromic, hydriodic, perchloric, sulfuric, nitric, phosphoric, acetic, propionic, glycolic, lactic, succinic, maleic, fumaric, malic, tartaric, citric, benzoic, mandelic, methanesulfonic, hydroxyethanesulfonic, benzenesulfonic, oxalic, pamoic, 2-naphthalenesulfonic, p-toluenesulfonic, cyclohexanesulfamic, salicylic, saccharinic or trifluoroacetic acid. Representative organic or inorganic bases include, but are not limited to, basic or cationic salts such as benzathine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium and zinc. 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 that 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 treatment of the various disorders described with the compound specifically disclosed or with WO 2007/121432 PCT/US2007/066772 37 a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administratior4Qthe 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. Representative hydroxy group prodrug forms include, but are not limited to, CI- 4 alkanylethers, substituted Cj. 4 alkanylethers, and C 14 alkanyl esters. Where the compounds according to this invention have at least one chiral center, 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. Furthermore, some of the crystalline forms for the compounds may exist as polymorphs and as such are intended to be included in the present invention. In addition, some of the compounds may form solvates with water (i.e., hydrates) or common organic solvents, and such solvates are also intended to be encompassed within the scope of this invention. Where the processes for the preparation of the compounds according to the 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 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 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 Chemistry, ed. J.F.W. McOmie, Plenum Press, 1973; and T.W. Greene & P.G.M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art. Even though the compounds of the present invention (including their pharmaceutically acceptable salts and pharmaceutically acceptable solvates) can be administered alone, they will generally be administered in admixture with a pharmaceutical carrier, excipient or diluent selected with regard to the intended route of administration and standard pharmaceutical or veterinary practice. Thus, the present invention is directed to pharmaceutical and veterinary compositions comprising compounds of Formula (1) and one or more pharmaceutically acceptable carriers, excipients or diluents. By way of example, in the pharmaceutical compositions of the present invention, the compounds of the present invention may be admixed with any WO 2007/121432 PCT/US2007/066772 40 suitable binder(s), lubricant(s), suspending agent(s), coating agentss, and/or solubilising agent(s). Tablets or capsules of the compounds may be administered singly or two or more at a time, as appropriate. It is also possible to administer the compounds in sustained release formulations. Alternatively, the compounds of the general Formula (1) can be administered by inhalation or in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder. An alternative means of transdermal administration is by use of a skin patch. For example, they can be incorporated into a cream consisting of an aqueous emulsion of polyethylene glycols or liquid paraffin. They can also be incorporated, at a concentration of between 1 and 10% by weight, into an ointment consisting of a white wax or white soft paraffin base together with such stabilizers and preservatives as may be required. For some applications, preferably the compositions are administered orally in the form of tablets containing excipients such as starch or lactose, or in capsules or ovules either alone or in admixture with excipients, or in the form of elixirs, solutions or suspensions containing flavoring or coloring agents. The compositions (as well as the compounds alone) can also be injected parenterally, for example intracavernosally, intravenously, intramuscularly or subcutaneously. In this case, the compositions will comprise a suitable carrier or diluent. For parenteral administration, the compositions are best used in the form of a sterile aqueous solution which may contain other substances, for example enough salts or monosaccharides to make the solution isotonic with blood.
WO 2007/121432 PCT/US2007/066772 41 For buccal or sublingual administration the ogmpositions may be administered in the form of tablets or lozenges which can be formulated in a conventional manner. By way of further example, pharmaceutical compositions containing one or more of the compounds of the invention described herein as the active ingredient can be prepared by intimately mixing the compound or compounds with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral). Thus for liquid oral preparations such as suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, stabilizers, coloring agents and the like; for solid oral preparations, such as powders, capsules and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Solid oral preparations may also be coated with substances such as sugars or be enteric-coated so as to modulate the major site of absorption. For parenteral administration, the carrier will usually consist of sterile water and other ingredients may be added to increase solubility or preservation. Injectable suspensions or solutions may also be prepared utilizing aqueous carriers along with appropriate additives. Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermalskin patches well known to those skilled in that art.
WO 2007/121432 PCT/US2007/066772 42 It is also apparent to one skilled in the art that the therapeutically effective dose for active compounds of the inventio pr a pharmaceutical composition thereof will vary according to the desired effect. Therefore, optimal dosages to be administered may be readily determined 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 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. Compounds of this invention may be administered in any of the foregoing compositions and dosage regimens or by means of those compositions and dosage regimens established in the art whenever use of the compounds of the invention is required for a subject in need thereof. The invention also provides a pharmaceutical pack or kit comprising one or more containers filled with one or more of the ingredients of the pharmaceutical and veterinary compositions of the invention. Optionally associated with such container(s) can be a notice in the form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration. For oral administration, a pharmaceutical composition is preferably provided in the form of tablets containing 0.01, 10.0, 50.0, 100, 150, 200, 250, and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the subject to be treated. Examples of condition intended to be within the scope of the present WO 2007/121432 PCT/US2007/066772 43 invention include, but are not limited to, diabetes, nephropathy, neuropathy, retinopathy, polycystic ovary syndrome, hypertension, ischemia, stroke, irritable bowel disorder, inflammation, cataract, cardiovascular diseases, Metabolic X Syndrome, hyper-LDL-cholesterolemia, dyslipidemia (including hypertriglyceridem ia, hypercholesterolemia, mixed hyperlipidemia, and hypo HDL-cholesterolem ia), atherosclerosis, obesity, and other disorders related to lipid metabolism and energy homeostasis complications thereof, Compounds of the present invention are also useful as PPAR delta agonists for treating, preventing, or inhibiting the progression of, a condition directly or indirectly mediated by PPAR delta. The compounds of the present invention are partcularly useful in treating diabetes, nephropathy, neuropathy, retinopathy, polycystic ovary syndrome, hypertension, ischemia, stroke, irritable bowel disorder, inflammation, cataract, cardiovascular diseases, Metabolic X Syndrome, hyper-LDL-cholesterolemia, dyslipidemia (including hypertriglyceridemia, hypercholesterole mia, mixed hyperlipidemia, and hypo-HDL cholesterolemia), atherosclerosis, obesity, and other disorders related to lipid metabolism and energy homeostasis complications thereof. In regard to the use of the present compounds in treatment of the disases or conditions such as those listed above, a therapeutically effective dose can be determined by persons skilled in the art by the use of established animal models.

For example, in Method 1, alkylation of the substituted benzoazepine 1-B with a compound of Formula 1-C where Ycan be a leaving group such as Br, CI, 1, mesylate, etc. under a basic condition, such as Cs2CO3 in CH 3 CN, can generate the corresponding compound of Id. In Method 2, reductive amination of 1-B with aryl aldehyde 1-D (e.g. R 5 = H) by using NaBH(OAc) 3 will generate Id; or reaction of 1-B with aryl ketone (e.g. R 5 = C-Ca alkyl) to give the shiff-base followed by reduction with NaCNBH 3 will generate Id. In Method 3, reaction of 1-B with aryl aldehyde 1 -E to give the shiff -base followed by reaction with organo-alkyl reagents such as Grignard reagents, CH 3 Li or organo-cupper reagent, will also provide Id.

To mimic a human hypercholesterolemic state in a rodent model, Sprague Dawley rats were fed a diet high in cholesterol (Research Diets, C13002) for 6 days before treatment with the compounds for another 8 days while remaining on the diet. Under this dietary regimen, the vehicle controls (HC: High Cholesterol) typically have serum total cholesterol and LDL-C levels that are increased by 3-8 fold and serum HDL C is decreased by approximately 30-50% compared with chow diet (Lean) controls. Treatment of Sprague Dawley rats fed the high cholesterol diet with Compound 7 for 8 days significantly increased HDL-C levels, achieving the levels of the chow fed controls (Chow). There were also significant decreases in serum total cholesterol and LDL-C levels. Compound 7 had no effect on serum triglycerides or liver weights. There were dose-related increases in drug plasma levels (Cmax and AUC) and there may be accumulation after multiple doses as evidenced by the differences in Cmax and AUC between the single and multiple doses at 3mg/kg.
