Biochem/physiol Actions

Fosbretabulin disodium (Combretastatin A4 phosphate, CA4P) is a potent vascular-disrupting agent (VDA). Fosbretabulin disodium is a prodrug that is converted to combretastatin A (Sigma Cat No. C7744) inside the endothelial cells that line blood vessels, where it binds to tubulin dimers and prevents microtubule polymerization, resulting in mitotic arrest and apoptosis in endothelial cells. Fosbretabulin disodium is a potent anti-cancer agent that exhibits antivascular effects on tumor vasculature, inducing a rapid reduction in tumor blood flow and a concomitant increase of cellular necrosis. Some of its activity is believed to involve interference with vascular endothelial-cadherin signaling in addition to its microtubule-disrupting activity.
