ZM 447439 is a novel, potent and selective inhibitor of Aurora kinase, a family of serine/threonine kinases essential for accurate chromosome segregation during cell division, that inhibits the activity of purified recombinant Aurora A and Aurora B proteins in vitro with 50% inhibition concentration IC50 values of 110 nM and 130 nM respectively and hence inhibits phosphorylation of histone H3 on serine 10. Being specifically for Aurora kinases, ZM 447439 barely inhibits the majority of other protein kinases (IC50 > 10 μM), such as CDK1/2/4, IKK1/2, PLK1, CHK1, cFLT2, KDR2, FAK and Zap-70, except for MEK1, SRC and LCK (IC50 values of 1.79 μM, 1.03 and 0.88 μM respectively μM).

In vitro kinase assays
Recombinant Aurora A and B were expressed as NH2-terminal His6-tagged fusion proteins using a baculovirus expression system. Aurora A was purified by affinity chromatography using Ni-NTA agarose, and Aurora B was purified by ion exchange chromatography using CM Sepharose Fast Flow. 1 ng purified recombinant enzyme was added to a reaction cocktail containing 25 mM Tris-HCl, pH 7.5, 12.5 mM KCl, 2.5 mM NaF, 0.6 mM DTT, 6.25 mM MnCl2, 10 μM peptide substrate, 10 μM ATP for Aurora A or 5 μM ATP for Aurora B, and 0.2 μCi γ-[33P]ATP (specific activity ≥ 2,500 Ci/mmol), and was then incubated at RT for 60 mins. Reactions were stopped by addition of 20% phosphoric acid, and the products were captured on P30 nitrocellulose filters and assayed for incorporation of 33P with a BetaplateTM counter. No enzyme and no compound control values were used to determine the concentration of ZM 447439, which gave 50% inhibition of enzyme activity.
