Discovery, design and synthesis of Y-shaped peroxisome proliferator-activated receptor delta agonists as potent anti-obesity agents in vivo

Abstract

We have discovered and demonstrated the in vitro and in vivo PPAR delta-selective activity of novel Y-shaped agonists. These compounds activated hPPAR delta with EC50 values between 1 and 523 nM. Surprisingly, compounds 10a, 11d, 11e and 11f were the most potent and most selective hPPAR delta agonists with 10(4)-fold selectivity over the other two subtypes, namely, hPPAR alpha and hPPAR gamma. The PPAR delta ligands 10a, 11e and 11f showed good bioavailability and in vivo efficacy.
