Ilorasertib hydrochloride (ABT-348 hydrochloride) is an ATP-competitive multitargeted kinase inhibitor, which inhibits Aurora C, Aurora B, and Aurora A (IC50s: 1 nM, 7 nM, 120 nM). It also suppresses RET tyrosine kinase, PDGFRβ, and Flt1 (IC50s: 7 nM, 3 nM, and 32 nM).
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.
