MedKoo Cat#: 462478 | Name: SCH-1473759 HCl
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

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.

Biological target:
SCH-1473759 HCl is an aurora inhibitor with IC50s of 4 and 13 nM for aurora A and B, respectively.
In vitro activity:
This study investigated SCH-1473759’s effects across a large panel of tumor cell lines from different tissue origin and genetic backgrounds. SCH-1473759 caused DNA content changes and inhibited cell growth after different exposure times. SCH 1473759 accelerated cell exit from mitosis following arrest induced by taxanes or KSP inhibitors. Reference: Cancer Chemother Pharmacol. 2011 Oct;68(4):923-33. https://pubmed.ncbi.nlm.nih.gov/21298383/
In vivo activity:
In this study, a novel UHPLC-MS/MS method was established to measure SCH-1473759 in murine plasma. There was a maximum plasma concentration of 34ng/mL at 1h, a half-life of 1h, and poor oral bioavailability (F=0.002).
