| | 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 | | Description | The Aurora kinases have important roles in regulating mitosis and cytokinesis, with Aurora B involved in centromere function as part of the Chromosomal Passenger Complex, with survivin, INCENP, and borealin. ZM 447439 is a selective inhibitor of Aurora B kinase (IC50 = 50 nM), less potently inhibiting Aurora C and A (IC50 = 250 and 1,000 nM, respectively). It has no effect on several other kinases, including Cdk1, Cdk2, Cdk4, Plk1, CHK1, KDR2, and FAK (IC50 > 10 μM). ZM 447439 has been used to study the role of Aurora B in molecular events associated with mitosis and cytokinesis. Moreover, ZM 447439 selectively inhibits proliferating cells rather than non-dividing cells, suggesting its potential in cancer therapy. | | 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 and 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. | | Definition | ChEBI: ZM447439 is a member of the class of quinazolines that is quinazoline which is substituted at positions 4, 6 and 7 by a (4-benzamidophenyl)nitrilo group, methoxy group and a 3-(morpholin-4-yl)propoxy group, respectively. It is an ATP-competitive inhibitor of Aurora A and Aurora B kinases with IC50 of 110 nM and 130 nM, respectively. It has a role as an Aurora kinase inhibitor, an antineoplastic agent and an apoptosis inducer. It is a member of benzamides, a member of quinazolines, an aromatic ether, a member of morpholines, a polyether, a secondary amino compound and a tertiary amino compound. | | storage | room temperature (desiccate) | | References | 1) Ditchfield et al (2003) Aurora B couples chromosome alignment with anaphase by targeting BubR1, Mad2, and Cenp-E to kinetochores; J.Cell Biol. 161 267
