Kif15-IN-2 is primarily used in research settings to study the role of Kif15, a kinesin motor protein, in cell division and mitosis. It acts as an inhibitor of Kif15, making it a valuable tool for understanding the mechanisms of spindle assembly and chromosome segregation during cell division. Researchers utilize this compound to investigate its potential in disrupting cancer cell proliferation, as Kif15 is often overexpressed in certain cancers. By inhibiting Kif15, Kif15-IN-2 helps explore new therapeutic strategies for targeting cancer cells while minimizing effects on normal cells. Additionally, it aids in studying the broader biological functions of kinesins in cellular processes.
