GW9508 is a selective agonist of GPR40 and 120 with pEC50 value of 7.32 ± 0.03 and 5.46 ± 0.09, respectively [1].
GPR40/120 belongs to G protein-coupled receptors (GPCRs) family and is activated by free fatty acids. Mucosal inflammation induced the overexpression of GPR40, GPR120, and several inflammatory cytokines, with correlations between ileal concentrations of tumor necrosis factor (TNF)-α and GPR expression levels [2] [3].
GW9508 is a GPR40/120 agonist and is different from the reported GPR40/120 agonist GW1100. When tested with HEK-293 (human embryonic kidney) cells expressing GPR40 or GRP120, GW9508 treatment increased intracellular Ca2+ concentration via activating GPR40/120 in a dose-dependent manner [1]. In rat pancreaticβ-cells, GW9508 treatment activated KATP channels which inhibited GSIS through agonist of GPR40 and GPR120 [4]. When tested with TNF-α treated rat L cells, administration of GW9508 increased the expression of GLP-2 via activating GPR40 and 120 [2].
