NCIt definition : A vascular disrupting agent (VDA), with potential anti-vascular and antineoplastic
activities. Upon administration, vascular disrupting agent BNC105 binds to tubulin
and inhibits its polymerization, which results in a blockage of mitotic spindle formation,
cell cycle arrest, and disruption of the tumor vasculature. This deprives tumor cells
of nutrients and results in tumor cell apoptosis. In addition to its VDA activity,
this agent has a direct cytotoxic effect on tumor cells by inhibiting tubulin polymerization.;
