Jump to navigation Jump to search. A mitotic inhibitor is a drug that inhibits mitosis, or cell division. These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division. The inhibition of microtubule polymerization by colchicine requires the formation of tubulin-colchicine complexes, and inhibition of polymerization is proportional to the concentration of tubulin-colchicine complexes rather than to the total concentration of colchicine. Because the formation of such complexes is slow relative to polymerization, the Both microtubule stabilizers and destabilizers can suppress microtubule dynamics. The drugs that can alter microtubule dynamics include: The cancer-fighting taxane class of drugs ( paclitaxel (taxol) and docetaxel ) block dynamic instability by stabilizing GDP-bound tubulin in the microtubule.

Evidence presented shows that melatonin has no effect on the in vitro assembly of bovine brain microtubules. [ 3 H]Colchicine binding is not inhibited by melatonin in either crude or purified tubulin preparations Glaziovianin A, an isoflavone isolated from the leaves of Ateleia glazioviana, inhibits the cell cycle progression in M-phase with an abnormal spindle structure, but its inhibitory mechanism has not been revealed. Here, we report that glaziovianin A and its derivatives are microtubule dynamics inhibitors. Glaziovianin A extended the time lag of tubulin polymerization without changing the net 11 Aug 2016 Multidrug resistance is a major limitation for microtubule-binding agents in cancer treatment. Here we report a novel microtubule inhibitor  Colchicine given together with paclitaxel, however, caused cells to adopt properties of normal cells.

2018-10-17 · Yet, microtubule alterations that are associated with resistance to microtubule-destabilizing drugs like vinca alkaloids or 2-methoxyestradiol did not confer cross-resistance to 6-AA, suggesting a different mechanism of microtubule interaction. Finally, 6-AA is the first-in-class microtubule inhibitor that features the unique anopterine scaffold. LIMK inhibition affects microtubule assembly in mitotic spindles. A549 cells were treated as indicated for 24 hours, then fixed and stained for DNA with DAPI (blue) and αTubulin (red) antibody.

A549 cells were treated as indicated for 24 hours, then fixed and stained for DNA with DAPI (blue) and αTubulin (red) antibody. Representative images of each type of mitotic defect observed are presented. Resistance to such microtubule inhibitors is complex and likely involves both pharmacokinetic (PK) effects and down-regulation of apoptosis pathways.
