Abstract
The discovery of PPAR antagonists is emerging as an useful tool for elucidating the biological role of the receptor. Here we report the identification of N-(phenylsulfonyl)amides containing the benzothiazole scaffold, a novel class of potent PPARα antagonists obtained from chemical modification of carboxylic acid agonists. In this work, a group of phenylsulfonamides were synthesized and in vitro evaluated against the agonistic effect of GW7647; they showed an inhibitory effect on PPARα activation, with best compounds revealing a dose-dependent antagonistic profile. Some of these antagonists showed also an inhibitory effect on CPT1A pattern expression.
