 ZM 447439 Usage And Synthesis 

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 against CDK1/2/4, Plk1, Chk1, etc. 

Features An Aurora selective ATP-competitive inhibitor. 

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 

Chemical Properties Pale Yellow Solid 

Uses It is a potent and selective inhibitor of Aurora B kinase. Cells treated with ZM-447439 progress through interphase, enter mitosis and assemble bipolar spindles but chromosome alignment, segregation a nd cytokinesis all fail. It induces apoptosos in Hep2 cancer cells and in acute myeloid leukemia cell lines but its propensity to induce polyploidy does not inevitably result in apoptosis.
