combretastatin a 1

Combretastatin A-1 phosphate (OXi-4503) tetrasodium, a prodrug of Combretastatin A-1, is a tubulin-binding microtubule polymerization inhibitor that targets the colchicine-binding site. By inducing tubulin depolymerization, Combretastatin A-1 phosphate tetrasodium inhibits the Wnt/β-catenin pathway and leads to the deactivation of AKT. It possesses both anti-tumor and anti-vascular properties.

Combretastatin A-1 is a potent microtubule inhibitor with anti-tumour and anti-vascular activity, acting through microtubule protein depolymerisation-mediated inactivation of AKT to inhibit the Wnt/β-catenin pathway, and can be used to study hepatocellular carcinoma.

Combretastatin A1 phosphate, a potent vascular disruptive agent, exhibits anti-angiogenic effects on tumors and holds potential for research on pancreatic neuroendocrine tumors.

isoCA-4 is a Combretastatin A4 derivative. isoCA-4 is a tubulin polymerization inhibitor with anti-proliferative activities [1].
