Synthesis and evaluation of aminomethyl dihydrocinnamates as a new class of PPAR ligands.

PPAR ligands with varied subtype selectivity have been synthesized using an achiral aminomethyl dihydrocinnamate template. Several compounds in this series have demonstrated potent plasma glucose and triglyceride lowering capability in rodent models of type 2 diabetes.

2-Alkoxydihydrocinnamates as PPAR agonists. Activity modulation by the incorporation of phenoxy substituents.

Herein we describe a series of potent and selective PPARgamma agonists with moderate PPARalpha affinity and little to no affinity for other nuclear receptors. In vivo studies in a NIDDM animal model (ZDF rat) showed that these compounds are efficacious at low doses in glucose normalization and plasma triglyceride reduction. Compound 1b (LY519818) was selected from our SAR studies to be advanced to clinical evaluation for the treatment of type II diabetes.
