General description

A cell-permeable azaindolylmaleimide compound that acts as a potent, specific, and ATP-competitive inhibitor of GSK-3β (Ki = 25 nM) and minimally inhibits a panel of 79 commonly studied protein kinases, including several PKC isozymes. Shown to increase intracellular glycogen synthase activity in HEK293 cells with an EC50 of 32 nM and demonstrate metabolic stability in human liver microsomes (HLM; t1/2 >100 min).
