Monastrolis a cell-permeable small molecule inhibitor discovered by Thomas U. Mayer in the lab ofTim Mitchison.Monastrol was shown to inhibit thekinesin-5 (also known asKIF11,Kinesin Eg5), amotor proteinimportant for spindle bipolarity.[1]

Mechanism of action
editMonastrol binds to a long loop that is specific to the Eg5 (also known asKIF11or kinesin-5) kinesin family, and allosterically inhibits ATPase activity of the kinesin[2]
