QUICK LINKS

Combretastatin A4 Phosphate Disodium Salt is a phosphorylated microtubule depolymerizing molecule which induces tumor necrosis by regression of unstable nascent tumor neovessels. 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.
