Description: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.
Price and Availability
BNC105P, purity > 98%, is not in stock, may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested.

Technical Data
Additional Information
BNC105P is the disodium phosphate ester prodrug of BNC105, a tubulin polymerization inhibitor (TPI) that exhibits a high degree of selectivity for tumor endothelial cells. BNC105P disrupts the vasculature within solid tumors in mice and acts as a direct antiproliferative, suppressing tumor cell growth in culture. BNC105P shows evidence of good efficacy in mice-bearing xenografts of several human-tumor types, causing the regression of tumors, and in some cases tumor clearance. Evaluations in preclinical models of cancer have shown that BNC105P is more potent and displays a significantly improved therapeutic index compared with other VDAs in development . BNC105P achieves >95% vascular disruption as early as 3 hours post administration in tumor bearing mice when dosed at 10 mg/kg. This dose is well tolerated as a Day 1, Day 8 dose in a 21-day treatment cycle. (source: Clin Cancer Res. 2011 Aug 1;17(15):5152-60.). BNC105P and BNC-105 are analogues of CA4 and CA4P their structures are showed as the following:Source: Clin Cancer Res. 2011 Aug 1;17(15):5152-60.
