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