Alisertib | Potent and selective inhibitor of Aurora A / Destabilizes Myc

Alisertib (MLN8237, 1028486-01-2) is a highly selective and potent (IC50 = 1 nM) cell permeable inhibitor of Aurora A with off-target binding at GABAA (IC50 = 490 nM).1 It disrupts the Aurora A-Myc complex leading to Myc degradation2 in Myc amplified neuroblastomas3 and p53-mutant human hepatocellular carcinoma cell4. Alisertib has been found to induce apoptosis and autophagy in breast cancer5 and melanoma6 cells via suppression of activation of the p38 MAPK pathway.
