Synthesis and biological evaluation of a novel series of substituted pentacyclic triterpene derivatives as potential PPARγ agoinsts and glycogen phosphorylase inhibitors have been described. Compounds 11 and 17 showed potent PPAR γ agonistic activity and activated the transcription activity of PPAR γ in a dose-dependent manner. On the other hand, eleven compounds exhibited moderate inhibitory activity against rabbit muscle glycogen phosphorylase a (RMGPa), and triterpene 10 was the best one. Structure-activity relationship (SAR) is also discussed.
