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.

Polo-like kinase-1 (Plk1) is activated before mitosis by Aurora A and its cofactor Bora. In mitosis, Bora is degraded in a manner dependent on Plk1 kinase activity and the E3 ubiquitin ligase SCF-betaTrCP. Here, we show that Plk1 is also

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
