aki001.

AKI-001 is a potent Aurora kinase inhibitor, which exhibits low nanomolar potency against both Aurora A and Aurora B enzymes, excellent cellular potency (IC50 < 100 nM), and good oral bioavailability. Phenotypic cellular assays show that both Aurora A and Aurora B are inhibited at inhibitor concentrations sufficient to block proliferation. Importantly, the cellular activity translates to potent inhibition of tumor growth in vivo. An oral dose of 5 mg kg QD is well tolerated and results in near stasis (92% TGI) in an HCT116 mouse xenograft model.
