Monastrol is a pyrimidine derivative inhibitor of kinesin Eg5 that inhibits ATPase activity and bipolar spindle formation. Monastrol exhibits anticancer activity, activating the spindle checkpoint but also inducing mitotic arrest and apoptosis in HeLa cells. Monastrol also induces dendrite growth and axonal shortening in neurons.
