[Inhibitors of microtubule polymerization- new natural compounds as potential anti-cancer drugs].

Inhibitors of microtubule polymerization are compounds which, by binding to the tubulin dimer, prevent the normal course of cell division and lead to cell death. They cause inhibition of mitosis, affect the cytoskeleton and disrupt the process of angiogenesis. Inhibitors of microtubule polymerization include natural substances, synthetic and semi-synthetic analogs. They contain a group of compounds having the ability to bind to the vinca alkaloid and colchicine domain of β-tubulin. Among them are vinca alkaloids, dolastatins and halichondrins, which connect to the vinca alkaloids domain, and combretastatins binding the colchicine site of protein. Tumor cells have greater capacity for cell proliferation and are also more susceptible to damage by microtubule inhibitors. Their action has been widely used in cancer therapy.
