  Synthesis of docosahexaenoic acid derivatives designed as novel PPARγ agonists and antidiabetic agents

  摘要：

  To discover novel peroxisome proliferator-activated receptor gamma (PPAR gamma) agonists that Could be used as antidiabetic agents, we designed docosahexacnoic acid (DHA) derivatives (2 and 3), which have a hydrophilic substituent at the C(4)-position, based on the crystal structure of the ligand-binding pocket of PPAR gamma. These compounds were synthesized via iodolactolic as a key intermediate. We found that both DHA derivatives (2 and 3) showed PPAR gamma transactivation higher than, or comparable to, that of pioglitazone, which is a TZD derivative used as an antidiabetic agent. DHA derivatives related to these potent Compounds 2 and 3 were also synthesized to study structure-activity relationships. Furthermore, 4-OH DHA 2, which shows strong PPAR gamma transcriptional activity, was separated as an optically pure form. (c) 2005 Elsevier Ltd. All rights reserved.

  We found that putative metabolites of docosahexaenoic acid (DHA) are strong PPARgamma activators and potential antidiabetic agents. We designed DHA derivatives based on the crystal structure of PPARgamma, synthesized them and evaluated their activities in vitro and in vivo. The efficacy of 5E-4-hydroxy-DHA 2a as a PPARgamma activator was about fourfold stronger than that of pioglitazone. Further-more, the 4-keto derivative (10b) showed antidiabetic activity in animal models without producing undesirable effects such as obesity and hepatotoxicity. (C) 2004 Elsevier Ltd.
