Upon administration of lisavanbulin and conversion into the active form BAL27862, this agent binds to tubulin at a site distinct from the vinca-alkaloid-binding site, and prevents tubulin polymerization and destabilizes microtubules, ultimately leading to cell cycle arrest, blockage of cell division and an induction of cell death in cancer cells."}]
