Abstract

GPR40 (FFA1) is a G-protein-coupled receptor, primarily expressed in pancreatic islets, the activation of which elicits increased Insulin secretion only in the presence of elevated glucose levels. A potent, orally bioavailable small molecule GPR40 agonist is hypothesized to be an effective antidiabetic posing little or no risk of Hypoglycemia. We recently reported the discovery of AMG 837 (1), a potent partial agonist of GPR40. Herein, we present the optimization from the GPR40 partial agonist 1 to the structurally and pharmacologically distinct GPR40 full agonist AM-1638 (21). Moreover, we demonstrate the improved in vivo efficacy that GPR40 full agonist 21 exhibits in BDF/DIO mice as compared to partial agonist 1.
