Description
The free fatty acid receptor 1 (FFAR1; GPR40) is highly expressed in pancreatic β-cells and activated by medium and long-chain fatty acids.
1 There is evidence of a link between FFAR1 (GPR40) and the ability of fatty acids to amplify glucose-stimulated insulin secretion, making this signaling pathway a potential target for regulating diabetes, obesity, and other metabolic disorders.
2,3 TAK-875 is a selective FFAR1 (GPR40) agonist (EC
50 = 26 nM) that does not exhibit activity on the related FFARs FFAR2 (GPR43) or FFAR3 (GPR41).

Uses
TAK-876 is a selective G protein-coupled receptor 40 (GPR40) agonist. TAK-876 is a novel oral medication that has been developed to improve the secretion of insulin in a glucose-dependent manner, whic
h has the potential to improve the control of blood sugar levels without the risk of hypoglycemia.
in vitro
tak-875 exhibited potent agonist activity and high binding affinity to the human receptor. in addition, tak-875 showed excellent agonist potency selectivity for gpr40 receptor over other members of the ffa receptor family (for which ec50>10 μm) [1].
