Abstact

Utilizing medicinal chemistry design strategies such as benzo splitting and ring expansion, we converted PPARalpha/gamma dual agonist 1 to selective PPARgamma agonists 19 and 20. Compounds 19 and 20 were 2- to 4-fold better than rosiglitazone at PPARgamma receptor, with 80- to 100-fold PPARgamma selectivity over PPARalpha receptor. X-ray cocrystal studies in PPARgamma and modeling studies in PPARalpha give molecular insights for the improved PPARgamma potency and selectivity for 19 when compared to 1.
