NCIt definition : A small-molecule inhibitor of Aurora kinases A, B and C with potential antineoplastic
activity. Aurora kinase inhibitor AMG 900 selectively binds to and inhibits the activities
of Aurora kinases A, B and C, which may result in inhibition of cellular division
and proliferation in tumor cells that overexpress these kinases. Aurora kinases are
serine-threonine kinases that play essential roles in mitotic checkpoint control during
mitosis and are overexpressed by a wide variety of cancer cell types.;
