Combretastatin A4 Phosphate Disodium Salt is the salt form of Combretastatin A4, a phosphorylated microtubule depolymerizing molecule which induces tumor necrosis by regression of unstable nascent tumor neo-vessels. Studies suggest that Combretastatin A4 Phosphate Disodium Salt selectively inhibits endothelial tumor cells via disrupting VE-cadherin (vascular endothelial-cadherin). In addition, Combretastatin A4 Phosphate Disodium Salt can increase the permeability of endothelial cells while inhibiting their migration and suppress capillary tube formation via disruption of VE-cadherin. Furthermore, Combretastatin A4 Phosphate Disodium Salt can change the morphology of endothelial cells by altering their tubulin cytoskeleton.
