A-769662 (844499-71-4) is a potent and reversible AMP-activated protein kinase (AMPK) allosteric activator. Activates AMPK by binding to the β and γ subunits and not the AMP binding site.1 EC50=0.8 mM for purified rat liver AMPK and inhibits fatty acid biosynthesis in rat hepatocytes IC50=3.2 mM.2 A-769662 inhibits the rate of whole-body fatty acid oxidation, decreases body weight gain, reduces plasma and liver triglycerides and lowers plasma glucose in ob/ob mice.2 Inhibits adipocyte differentiation.3 Prevents transcriptional activation of Oct4 and establishes a metabolic barrier to induced pluripotent stem cell reprogramming.4 A-769662 synergizes with AICAR.5 Cell permeable.
