Kif15-IN-1 is primarily used in research settings to study the role of the kinesin motor protein Kif15 in cellular processes. It is a potent and selective inhibitor of Kif15, making it valuable for investigating mechanisms of cell division, particularly in mitosis. Researchers utilize this compound to explore how inhibiting Kif15 affects spindle assembly, chromosome segregation, and overall mitotic progression. This has implications for understanding cancer biology, as Kif15 is often overexpressed in certain cancers, and its inhibition could potentially disrupt tumor cell proliferation. Additionally, Kif15-IN-1 serves as a tool for developing targeted therapies aimed at treating cancers dependent on Kif15 activity.
