Description

WO 2004/092145 PCT/IB2004/001159 -1 ALPHA SUBSTITUTED CARBOXYLIC ACIDS AS PPAR MODULATORS Background of The Invention This invention relates to alpha substituted carboxylic acids that modulate 5 the activities of peroxisome proliferator-activated receptor (PPAR), preferably two or more of PPAR-c, PPAR-8, or PPAR-y, enabling them to be useful in modulation of blood glucose and the increase of insulin sensitivity in mammals. This invention also relates to treatment of PPAR related disorders, such as diabetes, dyslipidemia, obesity and inflammatory disorders. 10 Peroxisome proliferators are a structurally diverse group of compounds which, when administered to rodents, elicit dramatic increases in the size and number of hepatic and renal peroxisomes, as well as concomitant increases in the capacity of peroxisomes to metabolize fatty acids via increased expression of the enzymes required for the 13oxidation cycle. Chemicals included in this group are 15 the fibrate class of hypolipidermic drugs, herbicides, and phthalate plasticizers (Reddy and Lalwani, Crit. Rev. Toxicol., 12:1-58 (1983)). Peroxisome proliferation can also be elicited by dietary or physiological factors such as a high-fat diet and cold acclimatization. Insight into the mechanism whereby peroxisome proliferators exert their 20 pleiotropic effects was provided by the identification of a member of the nuclear hormone receptor superfamily activated by these chemicals (Isseman and Green, Nature, 347-645-650 (1990)). This receptor, termed PPAR-a, was subsequently shown to be activated by a variety of medium and long-chain fatty acids and to stimulate expression of the genes encoding rat acyl-CoA oxidase and hydratase 25 dehydrogenase (enzymes required for peroxisomal p-oxidation), as well as rabbit cytochrome P450 4A6, a fatty acid Q-hydroxylase. PPAR-a activates transcription by binding to DNA sequence elements, termed peroxisome proliferator response elements (PPRE), as a heterodimer with the retinoid X receptor. The retinoid X receptor is activated by 9-cis retinoic acid 30 (see Kliewer, et al., Nature, 358:771-774 (1992), Gearing, et al., Proc. Natl. Acad. Sci. USA, 90:1440-1444 (1993), Keller, et al., Proc. Nat. Acad. Sci. USA, 90:2160 2164 (1993), Heyman, et al., Cell, 68:397-406 (1992), and Levin, et al., Nature, 355:359-361 (1992)). Since the PPAR-a-RXR complex can be activated by peroxisome proliferators and/or 9-cis retinoic acid, the retinoid and fatty acid 35 signaling pathways are seen to converge in modulating lipid metabolism. Since the discovery of PPAR-a, additional isoforms of PPAR have been identified, e.g., PPAR-8, or PPAR-y, which are spatially differentially expressed. Each PPAR receptor shows a different pattern of tissue expression, and WO 2004/092145 PCT/IB2004/001159 -2 differences in activation by structurally diverse compounds. PPAR-y, for instance, is expressed most abundantly in adipose tissue and at lower levels in skeletal muscle, heart, liver, intestine, kidney, vascular endothelial and smooth muscle cells as well as macrophages. Two isoforms of PPAR-y exist, identified as yi and y2, 5 respectively. PPAR-.ymediates adipocyte signalling, lipid storage, and fat metabolism. Evidence gathered to date support the conclusion that PPAR-y is the primary, and perhaps the only, molecular target mediating the insulin sensitizing action of one class of antidiabetic agents, the thiazolidine 2,4 diones. In a monotherapeutic or combination therapy context, new and established 10 oral antidiabetic agents are still considered to have non-uniform and even limited effectiveness. The effectiveness of oral antidiabetic therapies may be limited, in part, because of poor or limited glycemic control, or poor patient compliance due to unacceptable side effects. These side effects include edema, weight gain, or even more serious complications. For instance, hypoglycemia is observed in some 15 patients taking sulfonylureas. Metformin, a substituted biguanide, can cause diarrhea and gastrointestinal discomfort. Finally, edema, weight gain, and in some cases, hepatoxicity, have been linked to the administration of some thiazolidine 2,4 dione antidiabetic agents. Combination therapy using two or more of the above agents is common, but generally only leads to incremental improvements in 20 glycemic control. As a result, there is a need for antidiabetic agents that display combined PPAR-a and PPAR-y activation which should lead to the discovery of efficacious glucose and triglyceride lowering drugs that have great potential in the treatment of type 2 diabetes and the metabolic syndrome (i.e., impaired glucose tolerance, 25 insulin resistancem hyoertriglyceridemia and/or obesity).

The term "modulate" or "modulating", as used herein, refers to the ability of 30 a modulator for a member of the steroid/thyroid superfamily to either directly (by binding to the receptor as a ligand) or indirectly (as a precursor for a ligand or an inducer which promotes production of ligand from a precursor) induce expression of gene(s) maintained under hormone expression control, or to repress expression of gene(s) maintained under such control. 35 The term "obesity" or "obese", as used herein, refers generally to individuals who are at least about 20-30% over the average weight for his/her age, sex and height. Technically, "obese" is defined, for males, as individuals whose body mass index is greater than 27.8 kg/m, and for females, as individuals whose WO 2004/092145 PCT/IB2004/001159 -27 body mass index is greater than 27.3 kg/m2. Those of skill in the art readily recognize that the invention method is not limited to those who fall within the above criteria. Indeed, the method of the invention can also be advantageously practiced by individuals who fall outside of these traditional criteria, for example, by those 5 who may be prone to obesity. The term "Inflammatory disorders", as used herein, refers to disorders such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, psoriasis, chondrocalcinosis, gout, inflammatory bowel disease, ulcerative colitis, Crohn's disease, fibromyalgia, and cachexia. 10 The phrase "therapeutically effective amount", as used herein, refers to that amount of drug or pharmaceutical agent that will elicit the biological or medical response of a tissue, system, animal, or human that is being sought by a researcher, veterinarian, medical doctor or other. The phrase "amount . ..effective to lower blood glucose levels," as used 15 herein, refers to levels of compound sufficient to provide circulating concentrations high enough to accomplish the desired effect. Such a concentration typically falls in the range of about 10 nM up to 2 pM; with concentrations in the range of about 100 nM up to 500 nM being preferred. As noted previously, since the activity of different compounds which fall within the definition of Formula (I) as set forth above may 20 vary considerably, and since individual subjects may present a wide variation in severity of symptoms, it is up to the practitioner to determine a subject's response to treatment and vary the dosages accordingly. The phrase "insulin resistance", as used herein, refers to the reduced sensitivity to the actions of insulin in the whole body or individual tissues, such as 25 skeletal muscle tissue, myocardial tissue, fat tissue or liver tissue. Insulin resistance occurs in many individuals with or without diabetes mellitus. The phrase 'insulin resistance syndrome", as used herein, refers to the cluster of manifestations that include insulin resistance, hyperinsulinemia, non insulin dependent diabetes mellitus (NIDDM), arterial hypertension, central 30 (visceral) obesity, and dyslipidemia. The phrase "in combination with", as used herein, means that the alpha substituted carboxylic acids compound of Formula (I) may be administered shortly before, shortly after, concurrently, or any combination of before, after, or concurrently, with such other agents as described in the previous paragraphs. 35 Thus, the alpha substituted carboxylic acids compound of Formula (I) and the other agents may be administered simultaneously as either as a single composition or as two separate compositions or sequentially as two separate compositions.
WO 2004/092145 PCT/IB2004/001159 -28 Certain compounds of formula (I) may have asymmetric centers and therefore exist in different enantiomeric forms. All optical isomers and stereoisomers of the compounds of formula (I), and mixtures thereof, are considered to be within the scope of the invention. With respect to the compounds of formula (I), the 5 invention includes the use of a racemate, one or more enantiomeric forms, one or more diastereomeric forms, or mixtures thereof. The compounds of formula (I) may also exist as tautomers. This invention relates to the use of all such tautomers and mixtures thereof. Certain functional groups contained within the compounds of the present 10 invention can be substituted for bioisosteric groups, that is, groups which have similar spatial or electronic requirements to the parent group, but exhibit differing or improved physicochemical or other properties. Suitable examples are well known to those of skill in the art, and include, but are not limited to moieties described in Patini, et al., Chem. Rev, 1996, 96, 3147-3176 and references cited therein. 15 The subject invention also includes isotopically-labelled compounds, which are identical to those recited in Formula (I), but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, 20 carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as 2 H, 3 H, ' 3 C, 14 C, 15 sN, 180, 170, 31 p, 32 p 35 S, 1 8 F, and 3 6CI, respectively. Compounds of the present invention, prodrugs thereof, and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain 25 isotopically-labelled compounds of the present invention, for example those into which radioactive isotopes such as 3 H and 14 C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., 3 H, and carbon-14, i.e., 1 4 C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., H, 30 can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labelled compounds of Formula (I) of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the Schemes and/or in the Examples and 35 Preparations below, by substituting a readily available isotopically labelled reagent for a non-isotopically labelled reagent. This invention also encompasses pharmaceutical compositions containing and methods of treating bacterial infections through administering prodrugs of WO 2004/092145 PCT/IB2004/001159 -29 compounds of the formula 1. Compounds of formula 1 having free amino, amido, hydroxy or carboxylic groups can be converted into prodrugs. Prodrugs include compounds wherein an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues is covalently joined through an amide or 5 ester bond to a free amino, hydroxy or carboxylic acid group of compounds of formula 1. The amino acid residues include but are not limited to the 20 naturally occurring amino acids commonly designated by three letter symbols and also includes 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline homocysteine, 10 homoserine, omithine and methionine sulfone. Additional types of prodrugs are also encompassed. For instance, free carboxyl groups can be derivatized as amides or alkyl esters. Free hydroxy groups may be derivatized using groups including but not limited to hemisuccinates, phosphate esters, dimethylaminoacetates, and phosphoryloxymethyloxycarbonyls, as outlined in Advanced Drug Delivery Reviews, 15 1996, 19, 115. Carbamate prodrugs of hydroxy and amino groups are also included, as are carbonate prodrugs, sulfonate esters and sulfate esters of hydroxy groups. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers wherein the acyl group may be an alkyl ester, optionally substituted with groups including but not limited to ether, amine and carboxylic acid functionalities, or where 20 the acyl group is an amino acid ester as described above, are also encompassed. Prodrugs of this type are described in J. Med. Chem., 1996, 39, 10. Free amines can also be derivatized as amides, sulfonamides or phosphonamides.

All such isomers, including WO 2004/092145 PCT/IB2004/001159 -48 diastereomeric mixtures and pure enantiomers are considered as part of the invention. The compounds of formulas (I) that are basic in nature are capable of forming a wide variety of different salts with various inorganic and organic acids. 5 Although such salts must be pharmaceutically acceptable for administration to animals, it is often desirable in practice to initially isolate the compound of formula (I) from the reaction mixture as a pharmaceutically unacceptable salt and then simply convert the latter back to the free base compound by treatment with an alkaline reagent and subsequently convert the latter free base to a pharmaceutically 10 acceptable acid addition salt. The acid addition salts of the base compounds of this invention are readily prepared by treating the base compound with a substantially equivalent amount of the chosen mineral or organic acid in an aqueous solvent medium or in a suitable organic solvent, such as methanol or ethanol. Upon careful evaporation of the solvent, the desired solid salt is readily obtained. The desired acid 15 salt can also be precipitated from a solution of the free base in an organic solvent by adding to the solution an appropriate mineral or organic acid. Those compounds of formula (I) that are acidic in nature are capable of forming base salts with various pharmacologically acceptable cations. Examples of such salts include the alkali metal or alkaline-earth metal salts and particularly, the 20 sodium and potassium salts. These salts are all prepared by conventional techniques. The chemical bases which are used as reagents to prepare the pharmaceutically acceptable base salts of this invention are those which form non toxic base salts with the acidic compounds of formula (I). Such non-toxic base salts include those derived from such pharmacologically acceptable cations as sodium, 25 potassium calcium and magnesium, etc. These salts can easily be prepared by treating the corresponding acidic compounds with an aqueous solution containing the desired pharmacologically acceptable cations, and then evaporating the resulting solution to dryness, preferably under reduced pressure. Alternatively, they may also be prepared by mixing lower alkanolic solutions of the acidic compounds and the 30 desired alkali metal alkoxide together, and then evaporating the resulting solution to dryness in the same manner as before. In either case, stoichiometric quantities of reagents are preferably employed in order to ensure completeness of reaction and maximum yields of the desired final product.

WO 2004/092145 PCT/IB2004/001159 - 52 Methods of preparing various pharmaceutical compositions with a specific amount of active compound are known, or will be apparent, to those skilled in this art. For examples, see Remington's Pharmaceutical Sciences, Mack Publishing Company, Easter, Pa., 15th Edition (1975). 5 The examples and preparations provided below further illustrate and exemplify the compounds of the present invention and methods of preparing such compounds. It is to be understood that the scope of the present invention is not limited in any way by the scope of the following examples and preparations. In the following examples molecules with a single chiral center, unless otherwise noted, 10 exist as a racemic mixture. Those molecules with two or more chiral centers, unless otherwise noted, exist as a racemic mixture of diastereomers. Single enantiomers/diastereomers may be obtained by methods known to those skilled in the art. Where HPLC chromatography is referred to in the preparations and 15 examples below, the general conditions used, unless otherwise indicated, are as follows. The column used is a ZORBAXT m RXC18 column (manufactured by Hewlett Packard) of 150 mm distance and 4.6 mm interior diameter. The samples are run on a Hewlett Packard- 1100 systemA gradient solvent method is used running 100 percent ammonium acetate / acetic acid buffer (0.2 M) to 100 percent 20 acetonitrile over 10 minutes. The system then proceeds on a wash cycle with 100 percent acetonitrile for 1.5 minutes and then 100 percent buffer solution for 3 minutes. The flow rate over this period is a constant 3 ml / minute. In the following examples and preparations, "Et" means ethyl, "AC" means acetyl, "Me" means methyl, "ETOAC" or "ETOAc" means ethyl acetate, "THF" means 25 tetrahydrofuran, and "Bu" means butyl. Chiral supercritical fluid chromatography (SFC) conditions. Single enantiomers of certain racemic compounds were obtained by SFC using a chiralpak AD-H column at 140 bar and 2.5 mL/min, chiralpak AS-H column at 140 bar and 2.5 mL/min, chiralpak OJ-H column at 140 bar and 2.5 mL/min. 30 Throughout the following sections, compounds of the general formula below were prepared by procedures analogous to those described in Heterocycles, 2001, 55(4), 689-703.
