NCIt definition : A colchicine derivative and beta tubulin polymerization inhibitor, with potential
antineoplastic activity. Upon administration, beta tubulin polymerization inhibitor
CCI-001 targets, binds to and inhibits beta-III tubulin (TUBB3), 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. TUBB3, overexpressed
in many cancers, is associated with poor outcomes and a reduced response to taxane-based
microtubule-targeting antineoplastic agents.;
