A-
769662 is a small molecule thienopyridone that activates AMPK directly in cell-
free assays (EC
50 = 116 nM) and intact cells by allosterically activating AMPK and inhibiting its dephosphorylation on Thr
172.
1,2 A-
769662 specifically activates β1 subunit-
containing AMPK heterotrimers, and its effects are independent of kinases upstream of AMPK.
1,3 A-
769662 has been used to stimulate CYP450-
mediated fatty acid oxidation, inhibit adipocyte differentiation, explore glucose uptake in skeletal muscle, and promote endothelial cell survival during metabolic stress.
