    THIAZOLE OR OXAZOLE DERIVATIVES WHICH ARE USE FUL IN THE TREATMENT OF CARDIOVASCULAR AND RELATED DISEASES}
    [2] Many independent risk factors have been associated with cardiovascular disease. These risk factors include high blood pressure, elevated fibrinogen levels, high triglycerides, elevated LDL cholesterol, elevated total cholesterol, and low levels of HDL cholesterol. HMG CoA reductase inhibitors ("statin") are useful for treating diseases characterized by high LDL-c levels. Lowering LDL-c has not been found to be sufficient to reduce the risk of cardiovascular disease in some patients, especially patients with normal LDL-c levels. This population pool is identified by an independent risk factor called low HDL-c. The increased risk of cardiovascular disease associated with low HDL-c levels has not yet been successfully addressed by drug therapy [ie, drugs that are useful for raising HDL-c above 40% are not currently available; See Bisgaier, CL; Pape, ME Curr. Pharm. Des. 1998, 4, 53-70.
    [3] Syndrome X (including metabolic syndrome) is hyperinsulinemia, obesity, elevated levels of glycerides, uric acid, fibrinogen, small, dense LDL-c particles and plasminogen activator inhibitor 1 (PAI-1), and reduced It is defined vaguely as to refer to the abnormality including the level of HDL-c.
    [4] NIDDM is described as insulin resistance alternatingly leading to abnormal glucose production and a decrease in glucose uptake by skeletal muscle. These factors eventually lead to impaired glucose tolerance (IGT) and hyperinsulinemia.
    [5] Peroxysome proliferator active receptors (PPARs) are orphan receptors belonging to the steroid / retinoid receptor superfamily of ligand-activated transcription factors. Willson, TM and Wahli, W., Curr. Opin. Chem. Biol. , (1997), Vol. 1, pp 235-241].
    [6] Three mammalian peroxysome proliferator-active receptors were isolated and named PPAR-alpha, PPAR-gamma and PPAR-delta (also known as NUC1 or PPAR-beta). These PPARs regulate expression of target genes by binding to DNA sequence elements called PPAR response elements (PPREs). To date, PPRE has been identified in a number of gene enhancers encoding proteins that regulate lipid metabolism, suggesting that PPARs play a pivotal role in lipogenesis signaling cascades and lipid homeostasis (H. Keller and W. Wahli). , Trends Endocrin.Met 291-296, 4 (1993)).
    [7] Certain compounds that activate or otherwise interact with one or more PPARs have been associated with the regulation of triglycerides and cholesterol in animal models (see US Pat. Nos. 5,847,008 (Doebber et al.) And 5,859,051 (Adams et al.), And PCT publications WO 97/28149 (Leibowitz et al.) And WO 99/04815 (Shimokawa et al.).
    [8] Fibrate lowers serum triglycerides by 20-50%, lowers LDL-c by 10-15%, shifts LDL particle size from small, dense LDL-c, which is more atheromatous, to normal dense LDL-c. , One class of drugs that can increase HDL-c by 10-15%. Experimental evidence shows that the effect of fibrate on serum lipids is mediated through the activation of PPAR alpha. B. Staels et al., Curr. Pharm. Des., 1-14 , 3 (1), (1997). When PPAR alpha is activated, it increases the fatty acid catabolism in the liver and reduces the production of new fatty acids to transcribe enzymes resulting in reduced triglyceride synthesis and VLDL-c production / secretion. In addition, activation of PPAR alpha reduces the production of apoC-III. Reduction of apoC-III, an inhibitor of LPL activity, increases the elimination of VLDL-c. J. Auwerx et al., Atherosclerosis, (Shannon, Irel.), S29-S37 , 124 (Suppl), (1996) ]. PPAR alpha ligands may be useful for the treatment of dyslipidemia and cardiovascular disease. Fruchart, JC, Duriez, P., and Staels, B., Curr. Opin. Lipidol. (1999), Vol 10, pp 245-257.

In particular, the present invention relates to compounds that activate the alpha subtype ("hPPAR alpha") of the human peroxysome proliferator active receptor. The invention also relates to methods of making such compounds and methods of preventing or treating PPAR mediated diseases or disorders.

Moreover, it will be appreciated that the amount of the compound of the invention required for use in therapy depends ultimately on the discretion of the attending physician or veterinarian as it depends on the nature of the disease to be treated and the age and condition of the patient. In general, however, the dose used for the treatment of an adult human will typically be between 0.02 and 5000 mg, preferably between 1 and 1500 mg per day. The desired dose may conveniently be presented in one dose or in divided doses (eg, twice, three, four or more times per day) administered at appropriate intervals. The formulations according to the invention may contain 0.1 to 99% of the active ingredient, conveniently 30 to 95% for tablets and capsules, and 3 to 50% for liquid formulations.

Suitable doses will be readily appreciated by those skilled in the art.
    [75] The compounds of the present invention can be conveniently prepared by a general process in which a moiety such as (A) is bound to an acid (B) using a peptide coupling reaction. Such synthesis can preferably be carried out with acid groups protected by R.

Biol. Chem. , 1995, 270, 12953-6. Ligand binding domains for murine and human PPAR alpha, PPAR gamma and PPAR delta were fused to yeast transcription factor GAL4 DNA binding domains, respectively. CV-1 cells, along with reporter constructs containing five copies of the GAL4 DNA binding site that induce the expression of secreted placental alkaline phosphatase (SPAP) and β-galactosidase, are directed to each PPAR chimera. Transfection was transient using expression vectors. After 16 hours, the medium was exchanged with DME medium supplemented with 10% delipidized fetal calf serum and test compounds at appropriate concentrations. After an additional 24 hours, cell extracts were prepared and assayed for alkaline phosphatase and β-galactosidase activity. Alkaline phosphatase activity was corrected for transfection efficiency using β-galactosidase activity as internal standard. Kliewer, SA, et. al. Cell 83, 813-819 (1995).
