Used in preclinical research as a potent and selective inhibitor of Aurora A kinase, a key enzyme involved in cell division. Its primary application is in oncology drug development, where it helps study the role of Aurora A in tumor growth and mitotic regulation. Demonstrates antitumor activity in various cancer cell lines, particularly in models of solid tumors, making it a valuable tool compound for evaluating targeted cancer therapies. Often used in combination studies with other anticancer agents to assess synergistic effects and overcome drug resistance.
