Novel GPR40 agonist AS2575959 exhibits glucose metabolism improvement and synergistic effect with sitagliptin on insulin and incretin secretion

To our knowledge, this study is the first to demonstrate the synergistic effect of a GPR40 agonist and DPP-IV inhibitor on the glucose-dependent insulin secretion and GLP-1 concentration increase. These findings suggest that GPR40 agonists may represent a promising therapeutic strategy for the treatment of type 2 diabetes mellitus, particularly when used in combination with DPP-IV inhibitors.
