NCIt definition : A synthetic small molecule Aurora kinase (AK) inhibitor with potential antineoplastic
activity. Aurora kinase inhibitor SNS-314 selectively binds to and inhibits AKs A
and B, which may result in the inhibition of cellular division and proliferation in
tumor cells that overexpress AKs. AKs are serine-threonine kinases that play essential
roles in mitotic checkpoint control during mitosis.;
