产品描述:
AZD 5438 is a potent inhibitor of the cyclin-dependent kinases (CDKs) 1, 2, and 9 (IC50s = 16, 6, and 20 nM, respectively).{38013} AZD 5438 also inhibits the kinase activity of Cdk5/p25 and glycogen synthase kinase 3β (GSK3β) (IC50s = 14 and 17 nM, respectively). AZD 5438 induces cell cycle arrest by inhibiting phosphorylation of CDK-dependent substrates and exhibits in vitro antiproliferative activity against a range of tumor cell lines including lung, colorectal, breast, prostate, and hematologic tumors with IC50s ranging from 200 nM (MCF-7) to 1,700 nM (ARH-77).{38013,38014} AZD 5438 inhibits growth of human tumor xenografts derived from a wide range of cancer types and inhibits cell cycle proteins.{38013,38015}
