Application

Monastrol has been used:
  • to treat MDA-MB-231 cells as a non-microtubule-targeting agent
  • as a antineoplastic agent, to treat mouse myeloma cell line SP 2/0, to induce apoptosis and to elucidate the role of metabotropic glutamate receptor 3 (Grm3) in apoptosis
  • as an inhibitor of pteridine reductase in GFP-transfected promastigotes infected macrophages for flow cytometer-based growth inhibition assay and to evaluate anti-leishmanial activity of Leishmania donovani hamster model in vivo

Biochem/physiol Actions

Monastrol is a potent, cell-permeant inhibitor of mitosis. Monastrol arrested cells are characterized by monopolar spindles. This phenotype is induced through specific disruption of mitotic molecular motor kinesin Eg5 with IC50 at 14 μM. No effect on other motor proteins and tubulin.

Small molecules that perturb specific protein functions are valuable tools for dissecting complex processes in mammalian cells. A combination of two phenotype-based screens, one based on a specific posttranslational modification, the other visualizing microtubules and chromatin, was used to identify

Although Aurora B is important in cleavage furrow ingression and completion during cytokinesis, the mechanism by which kinase activity is targeted to the cleavage furrow and the molecule(s) responsible for this process have remained elusive. Here, we demonstrate that an
