TAK-875 (Fasiglifam) is the potent, selective and orally bioavailable partial GPR40 agonist with an EC50 ~14 nM. It has binding affinity to the human GPR40 receptor with Ki of 38 nM and the rat GPR40 receptor with Ki of 140 nM. TAK-875 has no agonist potency to other members of the FFA receptor family with EC50 >10 μM. The 2.3 Å resolution co-complex structure of hGPR40-TAK-875 reveals a unique binding mode of TAK-875 and suggests that entry to the non-canonical binding pocket most probably occurs via the lipid bilayer. Consistent with the activation of the Gqα-mediated signaling pathway, TAK-875 augments glucose-dependent insulin secretion in pancreatic β cells. Prolonged stimulation of GPR40/FFA1 by TAK-875 does not cause pancreatic β Cell dysfunction or induction of apoptosis. Termination phase III development of TAK-875 (Fasiglifam) for the potential treatment of type-2 diabetes mellitus was announced in 2013 due to concerns about liver safety.

How to use

In Vitro:

TAK-875 was used at 1 µM final concentration in various in vitro assays.

In Vivo:

TAK-875 was dosed to female Wistar fatty rats subjected to oral glucose tolerance test via oral gavage at 3 mg/kg one hour before an oral glucose challenge. Formulation is 0.5% CMC/0.25% Tween 80 in water. In type 2 diabetic N-STZ-1.5 rats, administration of TAK-875 (1-10 mg/kg PO) shows a clear improvement in glucose tolerance and augments insulin secretion. TAK-875 (10 mg/kg, PO) significantly augments plasma insulin levels and reduces fasting hyperglycemia in male Zucker diabetic fatty rats.
