bnc-105p

BNC105P is a benzofuran-based vascular disrupting agent (VDA) prodrug with potential anti-vascular and antineoplastic activities. Upon administration vascular disrupting agent BNC105P, the disodium phosphate ester of BNC105, is rapidly converted to BNC105; in activated endothelial cells, BNC105 binds to tubulin and inhibits its polymerization, which may result in a blockage of mitotic spindle formation, cell cycle arrest, and disruption of the tumor vasculature. Hypoxic conditions ensue, depriving tumor cells of nutrients and resulting in tumor cell apoptosis. In addition to its VDA activity, this agent has a direct cytotoxic effect on tumor cells by inhibiting tubulin polymerization. BNC105 is not a substrate for the multidrug-resistance P-glycoprotein (Pgp) transporter.

BNC105P is a benzo[b]furan-based vascular disrupting agent (VDA) prodrug with potential anti-vascular and anti-tumor effects. Upon administration, BNC105P, in its disodium phosphate form, rapidly converts to BNC105. In activated endothelial cells, BNC105 binds to tubulin and inhibits its polymerization, which may block spindle formation, cause cell cycle arrest, and dismantle the tumor vasculature. This creates a hypoxic environment, depriving tumor cells of nutrients, leading to apoptosis. Apart from its VDA activity, BNC105P also exerts direct cytotoxic effects on tumor cells by inhibiting tubulin polymerization. Notably, BNC105 is not a substrate for the multidrug-resistant P-glycoprotein (Pgp) transporter.
