The synthesis and structure-activity relationships of a novel series of ind
ole 5-carboxylic acids that bind and activate peroxisome proliferator-activ
ated receptor gamma (PPAR gamma) are reported. These new analogs are select
ive for PPAR gamma vs the other PPAR subtypes, and the most potent compound
s in this series are comparable to in vitro potencies at PPAR gamma reporte
d for the thiazolidinedione-based antidiabetic drugs currently in clinical
use. (C) 1999 Elsevier Science Ltd. All rights reserved.
