Aurora A Inhibitor I

Aurora A inhibitor I is a potent and selective inhibitor of Aurora A kinase (IC50s = 3.4 and 3,400 nM for Aurora A and Aurora B, respectively). It prevents centrosome separation and reduces phosphorylated Aurora A, but not phosphorylated histone H3, levels at the centrosomes, indicating inhibition is specific to Aurora A kinase. Aurora A inhibitor I reduces the proliferation of HCT116 and HT-29 colorectal carcinoma cells in vitro (IC50s = 0.19 and 2.9 µM, respectively).Formal Name: N-(2-chlorophenyl)-4-[[2-[[4-[2-(4-ethyl-1-piperazinyl)-2-oxoethyl]phenyl]amino]-5-fluoro-4-pyrimidinyl]amino]-benzamide.
