MONASTROL Chemical Properties,Usage,Production

Description

Monastrol (254753-54-3) is a potent, cell-permeable, small molecule inhibitor of mitosis. Monastrol-arrested cells are characterized by monopolar spindles.1?Does not affect other motor proteins or tubulin. Specifically inhibits the mitotic molecular motor kinesin Eg5, a motor protein required for spindle formation (IC50?= 14 μM).2?Mimics the effect of amyloid β on long term potentiation in a cellular model of learning and memory.3?Enhances regeneration of adult axons.4

Chemical Properties

Crystalline Solid

Uses

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

Uses

A cell-permeablesmall molecule inhibitor of the mitotic kinesin, Eg5, arrests cells in mitosis with monoastral spindles

Uses

Inhibitor of mammalian cell mitosis.

Definition

ChEBI: Monastrol is a racemate comprising equimolar amounts of R- and S-monastrol. It has a role as an antineoplastic agent, an EC 3.5.1.5 (urease) inhibitor, an antileishmanial agent and an antimitotic. It contains a (R)-monastrol and a (S)-monastrol.

Biological Activity

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 (IC 50 = 14 μ M).

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.
