Description: NOVEL BENZOXAZINONES AS PEROXISOME PROLIFERATOR ACTIVATED RECEPTOR GAMMA MODULATORS AND METHOD OF TREATMENT Cross Reference to Related Applications This application claims priority from U.S. Serial No. 60/203,859, filed May 12, 2000. Field of the Invention This invention relates to benzoxazinone derivatives useful for the treatment of Non-Insulin Dependant Diabetes Mellitus (NIDDM) and complications thereof and disorders related to lipid metabolism and energy homeostasis such as obesity. The compound acts through the Peroxisome Proliferator Activated Receptor gamma (PPARγ) , and is orally active as PPARγ modulator. Background of the Invention Diabetes is a disease caused by multiple factors and characterized by hyperglycemia which may be associated with increased and premature mortality due to an increased risk for microvascular and macrovascular diseases such as nephropathy, neuropathy, retinopathy, atherosclerosis, polycystic ovary syndrome (PCOS) , hypertension, ischemia, stroke, and heart disease. Type I diabetes (IDDM) results from genetic deficiency of insulin, the hormone regulating glucose metabolism. Type II diabetes is known as non- insulin dependent diabetes mellitus (NIDDM) , and is due to a profound resistance to insulin regulatory effect on glucose and lipid metabolism in the main insulin-sensitive tissues, i.e., muscle, liver and adipose tissue. This insulin resistance or reduced insulin sensitivity results in insufficient insulin activation of glucose uptake, oxidation and storage in muscle and inadequate insulin repression of lipolysis in adipose tissue as well as glucose production and secretion in liver. Many Type II diabetics are also obese, and obesity is believed to cause and/or exacerbate many health and social problems such as coronary heart disease, stroke, obstructive sleep apnoea, gout, hyperlipidemia, osteoarthritis, reduced fertility, and impaired psychosocial function. A class of compounds, thiazolidinediones (glitazones) , have been suggested to be capable of ameliorating many symptoms of NIDDM by binding to the peroxisome proliferator activated receptor (PPAR) family of receptors. They increase insulin sensitivity in muscle, liver and adipose tissue in several animal models of NIDDM resulting in correction of the elevated plasma levels of glucose, triglycerides and nonesteri ied free fatty acids without any occurrence of hypoglycemia . However, undesirable effects have occurred in animal and/or human studies including cardiac hypertrophy, hemadilution and liver toxicity. Most PPARγ agonists currently in development have thiazolidinedione ring as their common chemical structure. PPARγ agonists have been demonstrated to be extremely useful for the treatment of NIDDM and other disorders involving insulin resistance. Recently, troglitazone, rosiglitazone, and pioglitazone have been approved for treatment of type II diabetes. There is also indication that benzimidazole-containing thiazolidinedione derivatives may be used to treat irritable bowel disorder (IBD) , inflammation, and cataract (JP 10195057) . JP 09012576 (Yoshitake et al.) discloses benzothiazine derivatives stated as useful therapeutic agents for circulatory system disease and glaucoma. JP 09012575 (Hiroaki et al . ) discloses benzoxazine and benzothiazine derivatives stated to be useful as prophylactic drugs and/or therapeutic drugs in hyperlipemia, hyperglycemia, obesity, diseases attributable to sugar tolerance insufficiency, hypertension, osteoporosis, cachexia, and complications of diabetes such as retinopathy, nephrosis, neuropathy, cataract, coronary artery disease and arteriosclerosis. WO 99/20614 (Lohray et al . ) discloses β-aryl- - oxysubstituted alkylcarboxylic acids stated as antiobesity and hypocholesterolemic compounds which may have agonist activity against PPARα and/or PPARγ, and optionally inhibit HMG CoA reductase.

For example, alkyl radicals include methyl, ethyl, π-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, t-butyl, n- pentyl, 3- (2-methyl) butyl, 2-pentyl, 2-methylbutyl , neopentyl, π-hexyl, 2-hexyl, 2-methylpentyl, and the like. Alkoxy radicals are oxygen ethers formed from the previously described straight or branched chain alkyl groups . Cycloalkyl groups contain 3 to 8 ring carbons and preferably 5 to 7 ring carbons. Similarly, alkenyl and alkynyl groups include straight and branched chain alkenes and alkynes having 1 to 10 carbon atoms, or any number within this range. Unless otherwise stated, "aryl," employed alone or in combination with other terms (e.g., aryloxy, arylthioxy, arylalkyl) , is an aromatic radical which can be a single ring or multiple rings which are fused together or linked covalently. Illustrative aryl groups may be phenyl or naphthyl optionally substituted with one or more of the following: H, C x -C 10 alkyl, C 3 -C 8 cycloalkyl, COOR 1 , CONR , OH, Ci-Ci o alkyl ether, aryl or heterocyclyl ether, 0C(O)R 1 , OC(0)OR 1 , OC(0)NR 1 R 2 , NR X R 2 , NR 3 C(0)R\ NR 3 C(0)OR 1 , NR 3 C(0)NR 1 R 2 , halogen or halo (F, Cl, Br, I). "Heterocyclyl" or "heterocycle" is a 3- to 8-member saturated or unsaturated heterocyclic group containing 1-4 nitrogens, an oxygen, or a sulfur atom; or one nitrogen and either oxygen or sulfur. It is intended that the definition of any substituent or variable at a particular location in a molecule be independent of its definitions elsewhere in that molecule. It is understood that substituents and substitution patterns on the compounds of this invention can be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by techniques known in the art as well as those methods set forth herein. 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. The term "subject" as used herein, refers to an animal, preferably a mammal, most preferably a human, who has been the object of treatment, observation or experiment . Methods are known in the art for determining therapeutically and prophylactically effective doses for the instant pharmaceutical composition. The term "therapeutically effective amount" as used herein, means that amount of active 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 alleviation of the symptoms of the disease or disorder being treated. The term "prophylactically effective amount" refers to that amount of active compound or pharmaceutical agent that inhibits in a subject the onset of a disorder as being sought by a researcher, veterinarian, medical doctor or other clinician, the delaying of which disorder is mediated by modulating the actions of PPARγ. Depending upon the biological environment (e.g., cell type, pathological condition of the host, etc.), these compounds can activate or block the actions of PPARγ. The utility of the compounds to treat the above disorders in glucose and lipid metabolism can be determined according to the procedures described herein. The present invention therefore provides a method of treating disorders in glucose and lipid metabolism in a subject in need thereof which comprises administering any of the compounds as defined herein in a quantity effective to treat such disorders. The compound may be administered to a patient by any conventional route of administration, including, but not limited to, intravenous, oral, subcutaneous, intramuscular, intradermal and parenteral . The present invention also provides pharmaceutical compositions comprising one or more compounds of this invention in association with a pharmaceutically acceptable carrier. The pharmaceutical composition may contain between about 0.1 mg and 1000 mg, preferably about 100 to 500 mg, of the compound, and may be constituted into any form suitable for the mode of administration selected. Carriers include necessary and inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings. Compositions suitable for oral administration include solid forms, such as pills, tablets, caplets, capsules (each including immediate release, timed release and sustained release formulations) , granules, and powders, and liquid forms, such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions and suspensions. To prepare the pharmaceutical compositions of this invention, one or more compounds of the present invention or salt thereof of the invention as the active ingredient, is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral such as intramuscular. In preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed. Thus, for liquid oral preparations, such as for example, suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like; for solid oral preparations such as, for example, powders, capsules, caplets, gelcaps and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be sugar coated or enteric coated by standard techniques. For parenterals, the carrier will usually comprise sterile water, though other ingredients, for example, for purposes such as aiding solubility or for preservation, may be included. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed. The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful and the like, an amount of the active ingredient necessary to deliver an effective dose as described above. The pharmaceutical compositions herein will contain, per unit dosage unit, e.g., tablet, capsule, powder, injection, suppository, teaspoonful and the like, from about 0.01 mg to 30 mg/kg of body weight per day. Preferably, the range is from about 0.03 to about 15 mg/kg of body weight per day, most preferably, from about 0.05 to about 10 mg/kg of body weight per day. The compounds may be administered on a regimen of 1 to 2 times per day. The dosages, however, may be varied depending upon the requirement of the patients, the severity of the condition being treated and the compound being employed. The use of either daily administration or post-periodic dosing may be employed. Preferably these compositions are in unit dosage forms such as tablets, pills, capsules, powders, granules, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, auto-injector devices or suppositories; for oral parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. Alternatively, the composition may be presented in a form suitable for once- weekly or once-monthly administration; for example, an insoluble salt of the active compound, such as the decanoate salt, may be adapted to provide a depot preparation for intramuscular injection. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof . When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from 0.1 to about 500 mg of the active ingredient of the present invention. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release . A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate. The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, aqueous solutions, suitably flavoured syrups, aqueous or oil suspensions, and flavoured emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl- pyrrolidone or gelatin. The liquid forms in suitably flavored suspending or dispersing agents may also include the synthetic and natural gums, for example, tragacanth, acacia, methyl-cellulose and the like. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired. 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 transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen. For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when desired or necessary, suitable binders; lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include, without limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like. The daily dosage of the products may be varied over a wide range from 1 to 1000 mg per adult human per day. For oral administration, the compositions are preferably provided in the form of tablets containing, 0.01,0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250 and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. An effective amount of the drug is ordinarily supplied at a dosage level of from about 0.01 mg/kg to about 30 mg/kg of body weight per day. Particularly, the range is from about 0.03 to about 15 mg/kg of body weight per day, and more particularly, from about 0.05 to about 10 mg/kg of body weight per day. The compounds may " be administered on a regimen of 1 to 2 times per day. Optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, the mode of administration, and the advancement of the disease condition. In addition, factors associated with the particular patient being treated, including patient age, weight, diet and time of administration, will result in the need to adjust dosages. The compound of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of lipids, including but not limited to amphipathic lipids such as phosphatidylcholines, sphingomyelins, phosphatidylethanolamines, phophatidylcholines, cardiolipins, phosphatidylserines, phosphatidylglycerols, phosphatidic acids, phosphatidylinositols, diacyl trimethylammonium propanes, diacyl dimethylammonium propanes, and stearylamine, neutral lipids such as triglycerides, and combinations thereof. They may either contain cholesterol or may be cholesterol-free. From Formula I it is evident that some of the compounds of the invention may have one or more asymmetric carbon atoms in their structure. As represented in Formulae lb and Ic, the exo/endo orientation of a single bond is indicated by dotted hash (into the page) and solid hash (out of the page) , respectively. It is intended that the present invention includes within its scope the stereochemically pure isomeric forms of the compounds as well as their racemates . Stereochemically pure isomeric forms may be obtained by the application of art known principles. Diastereoisomers may be separated by physical separation methods such as fractional crystallization and chromatographic techniques, and enantiomers may be separated from each other by the selective crystallization of the diastereomeric salts with optically active acids or bases or by chiral chromatography. Pure stereoisomers may also be prepared synthetically from appropriate stereochemically pure starting materials, or by using stereoselective reactions. 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, Third Edition, John Wiley & Sons, 1999. The protecting groups may be removed at a convenient subsequent stage using methods known from the art . The chemistry of preparing compounds of Formula I is described in detail in U.S. Pat. Nos. 5,696,117 and 5,854,242, both to Frechette et al . , and WO 97/17333 (Frechette et al . ) , all of which are hereby incorporated by reference in their entirety. This invention will be better understood by reference to the schemes and examples that follow, but those skilled in the art will readily appreciate that these are only illustrative of the invention as described more fully in the claims which follow thereafter. The compounds of Formula I may be synthesized with the chemistry outlined in Scheme 1 wherein Z_ is hydrogen, halogen, C x -C 6 alkyl, alkoxy, phenyl, OH, amino, nitro, sulfonylamino or trifluoromethyl ; Z 2 is hydrogen or halogen; A is hexyl ; n is an integer from 0-3; and G is selected from (a) NHR 1 R 2 , N + R j R-R^- (b) NHC(NR 4 )NR 5 ; (c) C0 2 H, CHO; (d) CH(R 6 )C00H, CH(R 6 )COOCH 3 , CH=CHR 7 , CH=C(C00H) 2 ; (e) a moiety of the formula (f) 5-tetrazolyl, wherein R 1# R 2 and R 3 are independently hydrogen, alkyl, or t-butoxycarbonyl; R 4 and R 5 are independently t-butoxycarbonyl or hydrogen, or R 4 and R 5 may be joined together to form an imidazoline, imidazolyl or pyrimidine ring; R 6 is hydrogen, hydroxy, or halogen; and R 7 is C0 2 H or C(0)NH(CH 2 ) p OH wherein p is an integer from 1-4. 1 Scheme 1 In accordance with Scheme 1, the benzoxazinones can be made by conversion of a compound of the Formula 1 to a compound of the Formula 2. For example, when a chiral alcohol, such as ( S) - or (R) -2-hydroxybutyrolactone, is coupled under conditions that preserve stereochemical integrity, either by retention or inversion of absolute configuration, a chiral compound of the Formula 2 is obtained. A particularly useful example of this transformation is the use of the Mitsunobu reaction, which is delineated in the examples. In this reaction, a compound of the Formula 1 is exposed to a chiral secondary alcohol, such as 2-hydroxybutyrolactone, a phosphine, such as triphenylphosphine or tributylphosphine, and an azo compound, such as diethylazo dicarboxylate or the like, in a variety of non-protic solvents, such as THF, benzene, or DMF, to provide the corresponding ether of the general Formula 2. Maintaining stereochemical integrity throughout the course of the process provides chiral products la and lb. For example, the ether of the general Formula 2 is reduced to yield compound of the Formula 3 with a reagent such as hydrogen gas or ammonium formate, and a catalyst, such as palladium or platinum, in an appropriate solvent, such as methanol, ethanol, or ethyl acetate, at an appropriate temperature. The primary alcohol is protected with a variety of reagents, such as tert-butyldimethylsilyl chloride and imidazole, in a non- protic polar solvent, such as DMF or THF, with or without heating. The choice of protecting group may be easily determined by one skilled in the art. Substitution of the amide of the general Formula 3 by deprotonation with a base, such as an alkali metal hydride, in a non-protic polar solvent, such as DMF (N,N-dimethylformamide) or THF (tetrahydrofuran) , and addition of an alkyl halide or mesylate or tosylate or the like followed by deprotection of the alcohol gives compounds of general Formula 4. The choice of deprotection methods may be easily determined by one skilled in the art. The ether of the general Formula 5 can be obtained by a reaction such as the Mitsunobu reaction as described by Frechette, et al . , and delineated in the following examples . Deprotection of the alcohol gives the corresponding compounds of Formula 6 that can be further converted to the alkyl aryl ether of Formula la by adding HO-Ar- (CH 2 ) n G' (G' is G as described above other than -COOH) , which are commercially available and/or may be readily prepared by known methods. Thus deprotection of the ester to the acid yields the desired product of Formula lb. The following examples are intended to illustrate the invention but not to limit it.
