TUG-424 is a potent and selective free fatty acid receptor 1 (FFA1/GPR40) agonist with an EC50 of 32 nM. TUG-424 significantly increases glucose-stimulated insulin secretion at 100 nM. TUG-424 may serve to explore the role of FFA1 in metabolic diseases such as diabetes or obesity.

GPR40 Activator 1 is a potent GPR40 activator for treatment of type 2 diabetes.

HWL-088 is a highly potent and orally active free fatty acid receptor 1 (FFA1/GPR40) agonist (EC50 of 18.9 nM) with moderate PPARδ activity (EC50 of 570.9 nM) . HWL-088 improves glucose and lipid metabolism, and has anti-diabetic effects.
