Background

A-769662 is a potent activator of AMP-activated protein kinase (AMPK) by allosterically binding to the β and γ subunits and by inhibiting dephosphorylation of AMPK on Thr172 (1). This small molecule selectively targets AMPK heterotrimers containing the β1 subunit (2). A-769662 has been shown to stimulate purified rat liver AMPK (EC50 = 0.8 µM) and inhibit fatty acid synthesis in rat hepatocytes (IC50 = 3.2 µM) (3). Treatment of adipocytes with A-769662 inhibits cell differentiation, leads to over-activation of AMPK, and inactivation of acetyl-CoA carboxylase (ACC), making this an interesting compound when studying obesity (4).
