A labelled novel Aurora B kinase inhibitor with potential antineoplastic activity. It binds to and inhibits the activity of Aurora B, which may result in a decrease in the proliferation of tumor cells
that overexpress Aurora B. Aurora B is a positive regulator of mitosis that functions in the attachment of the mitotic spindle to the centromere; the segregation of sister chromatids to each daughter
cell; and the separation of daughter cells during cytokinesis.
