The Aurora kinases are a family of serine/threonine kinases that interact with components of the mitotic apparatus and serve as potential therapeutic targets in oncology. Herein, we reported a series of 2,4-bisanilinopyrimidines bearing 2,2,6,6-tetramethylpiperidine-N-oxyl with selective inhibition of Aurora A in either enzymatic assays or cellular phenotypic assays, and displaying more potent anti-proliferation compared with that of VX-680. The most potent compound 10a forms better interaction with Aurora A than Aurora B in molecular docking. Mechanistic studies revealed that 10a disrupt the spindle formation, block the cell cycle progression in the G2/M phase and induce Apoptosis in HeLa cell. These results suggested that the produced series of compounds are potential Anticancer agents for further development as selective Aurora A inhibitors.
