General description

A potent cell-permeable and reversible inhibitor of glycogen synthase kinase-3β (IC50 = 230 nM), Lck (IC50 = 470 nM), and cyclin-dependent kinases (Cdks). Inhibits Cdk1/cyclin B (IC50 = 400 nM), Cdk2/cyclin A (IC50 = 680 nM), Cdk2/cyclin E (IC50 = 7.5 µM), and Cdk5/p25 (IC50 = 850 nM). Also inhibits other kinases such as c-Src (IC50 = 15 µM), casein kinase II (IC50 = 20 µM), ERK1 (IC50 = 20 µM), and ERK2 (IC50 = 9 µM). Inhibition is competitive with respect to ATP binding.
