Peroxisome proliferator-activated receptor gamma (PPARgamma) is involved in glucose and lipid homeostasis. PPARgamma agonists are in clinical use for the treatment of type 2 diabetes. Lately, a new class of selective PPARgamma modulators (SPPARgammaMs) was developed, which are believed to show less side effects than full PPARgamma agonists. We have previously shown that alpha-substitution of pirinixic acid, a moderate agonist of PPARalpha and PPARgamma, leads to low micromolar active balanced dual agonists of PPARalpha and PPARgamma. Herein we present modifications of pirinixic acid leading to subtype-selective PPARgamma agonists and furthermore the development of a selective PPARgamma modulator guided by molecular docking studies.
