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.
