Discovery of a potent G-protein-coupled receptor 119 agonist for the treatment of type 2 diabetes.

The ever-growing prevalence of Type-2 diabetes in the world has an urgent need for multiple orally effective agents that can regulate glucose homeostasis. G-Protein coupled receptor 119 (GPR 119) agonists have demonstrated the glucose-dependent insulin secretion and showed beneficial effects on glycemic control in humans and/or relevant animal models. Herein, we describe our efforts towards identification of a potent and oral GPR 119 agonist 13c (ZY-G19), which showed in vitro potency in the cell-based assay and in vivo efficacy without exerting any significant signs of toxicity in relevant animal models.
