  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.

  (−)-Cercosporamide derivatives as novel antihyperglycemic agents

  摘要：

  In our exploratory campaign for an antihyperglycemic agent with a novel mechanism of action, (-)-Cercosporamide 1, which is known as an antifungal agent, showed a potent plasma glucose lowering effect in hyperglycemic KK/Ta mice. The trouble was that it was accompanied by a decrease in food intake and a loss of body weight. We synthesized some (-)-Cercosporamide derivatives and succeeded to separate these actions. N,O-ketal type derivatives, especially compound 10, had the most potent plasma glucose lowering effect without affecting the food consumption or body weight. (C) 2008 Elsevier Ltd.
