General description

A potent, cell-permeable, non-tubulin-interacting mitosis inhibitor. Arrests mammalian cells in mitosis with monopolar spindles. In vitro, it specifically inhibits the motility of the mitotic kinesin Eg5, a motor protein involved in the assembly and maintenance of the mitotic spindle (IC50 = 14 µM).
