SNS-314 Mesylate (1146618-41-8) Description

SNS-314 is 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.

SNS-314 blocks proliferation in a broad panel of tumor cell lines (HCT116, A2780, PC-3, HeLa, MDA-MB-231, H-1299, and HT29) with IC50 values ranging from 1.8 nM in A2780 ovarian cancer cells to 24 nM in HT29 colon cancer cells. In the HCT116 human colon cancer xenograft model, administration of 50 and 100 mg/kg SNS-314 leads to dose-dependent inhibition of histone H3 phosphorylation for at least 10 h. SNS-314 shows significant tumor growth inhibition in a dose dependent manner under a variety of dosing schedules including weekly, bi-weekly, and 5 days on/9 days off.
