Monastrol 生物活性

描述 Kinesin-5 motors are one of the members of microtubule-dependent superfamily which are responsible for generating outward forces for establishing and maintaining spindle bipolarity and contributing to microtubule flux[3]. Monastrol is a cell-permeable inhibitor of the kinesin-5 with IC50 value of 9 - 22 µM for all kinesin-5 constructs[4]. The HeLa cells were treated with 100 μmol/L of monastrol for 30 hours. The mitotic index was determined using formaldehyde fix and Hoechst DNA stain and it was found that the treatment of monastrol induced mitotic arrest which peaked at 18 hours. The poly (ADP-ribose) polymerase coincided was cleavage and the mitotic marker phospho-histone H3 level was decreased after the treatment of monastrol as analyzed by western blotting assay[5]. The C57BL/6J mice were treated with 1 mg/kg monastrol intraperitoneally 10 min before the treatment of bortezomib for 28 days. The treatment of monastrol substantially alleviated morphological features of axonal injury and functional measures of sensory neuropathy as examined by H&E staining[6].
作用机制 The monastrol binds a complex of kinesin-5 and ADP. It inhibited the release of the microtubule-stimulated ADP from kinesin-5 through an allosteric mechanism[7].
