Definitions
- the present invention relates to the compound represented by formula ( I ) as a PPAR (Peroxisome Proliferator Activated Receptor) ligand and a hydrate, a solvate, a stereoisomer and a pharmaceutically acceptable salt thereof, which can be used for the treatment of obesity, hyperlipidemia, arteriosclerosis and diabetes, and a pharmaceutical composition, a cosmetic composition, an strengthening agent, a memory improving agent, a therapeutic agent for dementia and Parkinson's disease, a functional food and a feed composition containing the same.
- PPAR Peroxisome Proliferator Activated Receptor
- PPAR Peroxisome Proliferator Activated Receptor
- PPAR ⁇ , PPAR ⁇ and PPAR ⁇ have tissue specific functions in vivo and different regions for expression.
- PPAR ⁇ is mainly expressed in the heart, kidney, skeletal muscle and large intestine in human (MoI. Pharmacol. 1998, 53, pl4-22., Toxicol. Lett. 1999, 110, pll9- 127, J " . Biol. Chem.
- PPAR ⁇ is expressed in the skeletal muscle at a low level but mainly expressed in the adipose tissue to induce the adipocyte differentiation and to store energy as the form of fat, and is involved in homeostatic regulation of insulin and glucose (Moll. Cell. 1999, 4, p585-594., p597-609., p611-617).
- PPAR ⁇ is preserved evolutionarily in mammals including human and vertebrates including rodents and sea squirts.
- PPAR ⁇ The first PPAR ⁇ found in Xenopus laevis was known as PPAR ⁇ (Cell 1992, 68, p879-887) and PPAR ⁇ found in human was named differently as NUCl (MoI. Endocrinol. 1992, 6, pl634-1641) , PPAR ⁇ (Proc. Natl. Acad. Sci. USA 1994, 91, p7355-7359) , NUCl (Biochem. Biophys. Res. Commun. 1993, 196, p671-677) , FAAR (J " . Bio. Chem. 1995, 270, p2367-2371), ect, but they have been renamed as PPAR ⁇ recently.
- NUCl MoI. Endocrinol. 1992, 6, pl634-1641
- PPAR ⁇ Proc. Natl. Acad. Sci. USA 1994, 91, p7355-7359
- NUCl Biochem. Biophys. Res
- PPAR ⁇ is known to exist in chromosome 6p21.1-p21.2.
- PPAR ⁇ mRNA is found in various cells but the level is lower than those of PPAR ⁇ or PPARy (Endocrinology 1996, 137, p354-366., J " . Bio. Chem. 1995, 270, p2367-2371, Endocrinology 1996, 137, p354-366) .
- the previous studies confirmed that PPAR ⁇ plays an important role in the reproductive cell expression (Genes Dev. 1999, 13, pl561-1574) and has physiological functions of differentiating neuronal cells (J " . Chem.
- PPAR ⁇ activates the expression of key gene involved in ⁇ -oxidation in fatty acid catabolism and uncoupling proteins (UCPs) , the gene involved in energy metabolism, which brings the effect of improving obesity (Nature 2000, 406, p415-418, Cell 2003, 113, pl59-170, PLoS Biology 2004, 2, pl532-1539) .
- the activation of PPAR ⁇ increases the HDL level, improves type 2 diabetes without weight changes (Proc. Natl. Acad. Sci.
- PPAR ⁇ is involved in the mitochondria generation and the muscle fiber conversion in muscles to enhance endurance.
- Muscles have fatty acid catabolism muscle fiber (Type I ) that enhances endurance and glycoclastic muscle fiber (Type II) that enhances power.
- Fatty acid catabolism muscle fiber (Type I ) which is responsible for enhancing endurance is red because it has plenty of mitochondria and myoglobin.
- glycoclastic muscle fiber (Type II) which is responsible for enhancing power is white.
- Type I muscle fiber was increased significantly, in addition to the increase of myoglobin, electron transport system enzymes (cytochrome c, cytochrome c oxidases II and IV) and fatty acid ⁇ oxidase. Therefore, constant running time and distance were respectively 67% and 92% increased, compared with wild type rats (PLoS Biology, 2004, 2:e294).
- Synthetic PPAR ⁇ ligands developed so far have less selectivity, compared with other PPAR ⁇ and PPARy ligands.
- the early selective ligand was L-631033, developed by Merk (J. Steroid Biochem. MoI. Biol. 1997, 63, pl-8) , which was produced by introducing a functional group being able to fix side chain based on its natural fatty acid morphology.
- the same research team reported later more effective ligand L- 165041 (J. Med. Chem. 1996, 39, p2629-2654), in which the compound known as a leukotriene agonist is functioning to activate human PPAR ⁇ .
- the PPAR ⁇ selective ligand GW501516 ( [2 -methyl-4- [ [ [4- methyl-2- [4- (trifluoromethyl) phenyl] -1, 3-thiazol-5- yl] methyl] sulfanyl] phenoxy] acetic acid), developed by GlaxoSmithKline, exhibits much better physiological effect than any other ligands previously developed (Proc. Natl. Acad. Sci. USA 2001, 98, p5306-5311) .
- the GW501516 has excellent affinity (1-10 nM) to PPAR ⁇ , and excellent selectivity to PPAR ⁇ or PPAR ⁇ as well, which is at least 1000 times the selectivity of earlier ligands.
- the thiazole compound represented by formula A as a PPAR ⁇ selective activator has been described in WO 2001-00603 and WO 2002-62774 applied by Glaxo group and WO 2003-072100 applied by Eli Lilly.
