Chemical Name: 9-Bromo-7,12-dihydro-indolo[3,2-d][1]benzazepin-6(5H)-one

Biological Activity

Potent inhibitor of CDK1/cyclin B and GSK-3β (IC50 values are 0.4 and 0.23 μM respectively). Also inhibits CDK2/cyclin A, CDK2/cyclin E and CDK5/cyclin/p35 (IC50 values are 0.68, 7.5 and 0.85 μM respectively). Selective over c-src (IC50 = 15 μM), casein kinase 2 (IC50 = 20 μM), ERK1 (IC50 = 20 μM), ERK2 (IC50 = 9 μM) and a range of other protein kinases (IC50 values > 35 μM). Generates induced pluripotent stem cells (iPSCs) from somatic cells when used in combination with reprogramming factors; can replace Klf4.
