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.1 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).2 It has no effect on several other kinases, including Cdk1, Cdk2, Cdk4, Plk1, CHK1, KDR2, and FAK (IC50 > 10 µM).3 ZM 447439 has been used to study the role of Aurora B in molecular events associated with mitosis and cytokinesis.3,4 Moreover, ZM 447439 selectively inhibits proliferating cells rather than non-dividing cells, suggesting its potential in cancer therapy.2
