NCIt definition : A water-soluble phosphate prodrug of N-acetylcolchinol with potential antiangiogenesis
and antineoplastic activities. ZD-6126 is converted in vivo into N-acetylcolchinol.
N-acetylcolchinol binds to and destabilizes the tubulin cytoskeleton of endothelial
cells in tumor blood vessels, which may result in tumor endothelial cell apoptosis,
the selective occlusion of tumor blood vessels, cessation of tumor blood flow, and
tumor necrosis.;
Alternative definition : NCI-GLOSS: A substance that has been studied in the treatment of several types of
cancer. ZD6126 destroys blood vessels in tumors and may prevent the growth of new
blood vessels that tumors need to grow. It is a type of vascular targeting agent and
a type of antiangiogenesis agent.;
