Biological Activity

Monastrol is a potent, cell-permeable, small molecule mitosis inhibitor that does not interact with tubulin. Arrests cells in mitosis and specifically inhibits the motility of the mitotic kinesin Eg5, a motor protein required for mitotic spindle formation and maintenance (IC50 = 14 μM).

Technical Data

Soluble to 20 mM in ethanol and to 100 mM in DMSO
Store at RT
