ZM447439

ZM447439 is an Aurora kinase B inhibitor, suppresses the growth of cervical cancer SiHa cells and enhances the chemosensitivity to cisplatin. Aurora family kinases play roles in several mitotic processes, including the G2/M transition, mitotic spindle organization, chromosome segregation, and cytokinesis. ZM447439 has dramatic effects on chromosome morphology and spindle dynamics. ZM-447439 can reduce the number of SiHa cells, increase the volume of cells and lead to apoptosis. The growth of SiHa cells treated with ZM447439 was inhibited in dose- and time-dependent manners. ZM447439 significantly inhibited the expression of Aurora-B and H3-P protein (P < 0.05). ZM-447439 selectively over a range of other kinases such as Cdk1 and PLK1 (up to 10mM). Additionally, aurora kinase inhibition by ZM447439 potently induced apoptosis, which was accompanied by DNA fragmentation and caspase 3 and 7 activation.
