SNS-314 Mesylate (SNS-314) is an effective and specific Aurora A/B/C inhibitor (IC50: 9/31/3 nM). It is less inhibition of Trk A/B, Fms, Flt4, c-Raf, Axl, and DDR2.

SNS-314, a synthetic small molecule Aurora kinase (AK) inhibitor with potential antineoplastic activity, selectively binds and inhibits AKs A and B, resulting in the inhibition of cell division and proliferation in tumor cells that overexpress AKs.
