Discovery of a novel selective PPARγ modulator from (−)-Cercosporamide derivatives
摘要:
In an investigation of (-)-Cercosporamide derivatives with a plasma glucose-lowering effect, we found that N-benzylcarboxamide derivative 4 was a partial agonist of PPAR gamma. A SAR study of the substituents on carboxamide nitrogen afforded the N-(1-naphthyl) methylcarboxamide derivative 23 as the most potent selective PPAR gamma modulator. An X-ray crystallography study revealed that compound 23 bounded to the PPAR gamma ligand binding domain in a unique way without any interaction with helix12. Compound 23 displayed a potent plasma glucose-lowering effect in db/db mice without the undesirable increase in body fluid and heart weight that is typically observed when PPAR gamma full agonists are administrated.
