Description: SCH-1473759 is a potent and selective Aurora A/B inhibitor with IC50 sub-nanomolar. SCH 1473759 was active against a large panel of tumor cell lines from different tissue origin and genetic backgrounds. SCH-1473759 demonstrated potent mechanism-based activity, and activity was shown to be enhanced in combination with taxanes and KSP inhibitors. This information may be useful for optimizing the clinical efficacy of Aurora inhibitors.
