Used primarily in cancer research, particularly for acute myeloid leukemia (AML). It selectively inhibits Aurora B kinase, a protein involved in cell division, leading to polyploidy and apoptosis in tumor cells. Shows potent anti-proliferative effects in hematological malignancies. Investigated for its ability to target rapidly dividing cells with minimal effect on normal cells, making it a candidate for targeted chemotherapy. Also used as a tool compound to study mitotic mechanisms in cellular biology.
