G protein coupled receptor 40 (GPR40) is a potential target for treatment of type 2 diabetes. Herein, the well-known GPR40 agonist TAK-875 (compound 1) was synthesized as a positive control. Besides, an epimeric mixture 11, which was the sulfoxide analog of compound 1 was also synthesized. The following chiral HPLC separation of 11 led to optically pure compounds 12 (S,S, 100.0% de) and 13 (R,S, 100.0% de), of which the absolute configurations were determined by circular dichroism spectra analysis. In vitro biological activity evaluation results showed that the GPR40 agonistic potency of epimeric mixture 11 (EC50=77.5 nmol·L-1) and its two optically pure epimers (12, EC50=76.1 nmol·L-1; 13, EC50=114.0 nmol·L-1) were comparable to that of compound 1 (EC50=84.3 nmol·L-1), which was rationalized by docking analysis. Compounds 12 and 13 warrant further drug-like property evaluation due to their promising potency and novel structures.
