Used primarily in research as a potent inhibitor of kinesin spindle protein (KSP), this compound plays a role in anticancer drug development. It interferes with mitotic cell division by preventing proper spindle formation, leading to cell cycle arrest in rapidly dividing tumor cells. Due to its selective mechanism, it shows potential for treating solid tumors with reduced impact on non-dividing cells. It is also employed as a biochemical tool to study mitosis and cellular proliferation pathways.
