A potent and selective ATP-competitive dual inhibitor cdc7/cdk9. It blocks DNA synthesis and affects the phosphorylation of the replicative DNA helicase at Cdc7-dependent phosphorylation sites. Inhibits cell proliferation in a variety of human cell lines and induces apoptosis in a p53-independent manner in vivo. Also inhibits mitogen-activated protein kinase-activated protein kinase-2 (MK-2).
