Description
ZM 447439 is a selective and ATP-competitive inhibitor for Aurora A and Aurora B with IC50 of 110 nM and 130 nM, respectively. It is more than 8-fold selective for Aurora A/B than MEK1, Src, Lck and has little effect againstCDK1/2/4, Plk1, Chk1, etc.

In vitro
In vitro, ZM-447439 selectively inhibits recombinant human Aurora A and B with IC50 values of 110 and 130 nM, respectively, while other protein kinases of diverse structural types including the mitotic kinases CDK1 and PLK1 are inhibited with IC50 values >10 μM. Aurora kinase inhibitor, ZM-447439 time- and dose-dependently inhibits the growth of all three cell lines with IC50 values of 3 μM (BON), 0.9 μM (QGP-1) and 3 μM (MIP-101) after 72 hours of continuous exposure. In addition, ZM-447439 potently induces cell apoptosis by promoting DNA fragmentation and caspase 3 and 7 activation, and arrests GEP-NET cells in the G0 /G1and G2/M phase of the cell cycle.In mouse embryo, inhibition of Aurora kinase activity by ZM-447439 results in abnormalities during mitosis by regulating the phosphorylation of histone H3 serine 10 (H3S10Ph) from G2 to metaphase with different perturbations in each embryonic cycle.A recent study shows that ZM-447439 exhibits growth inhibitory and proapoptotic effect on cervical cancer SiHa cells, and enhances the chemosensitivity to cisplatin.
