General description

Ombrabulin is a member of the combretastatin A-4 compound class and is a tubulin-depolymerising tumour vascular-disrupting compound.

Biochem/physiol Actions

Ombrabulin leads to the constriction of the arteries, inhibits cell proliferation and causes detachment of endothelial cells, thereby leading to cytotoxicity. In pre-clinical studies, this compound, along with cisplatin, has shown anti-tumor activity. In tumors, it is responsible for the destruction of the vasculature.
Ombrabulin is a synthetic water-soluble combretastatin analog vascular disrupting agent. Ombrabulin is a tubulin polymerization inhibitor. Ombrabulin binds to the colchicine binding site of endothelial cell tubulin, inhibiting tubulin polymerization and inducing mitotic arrest and apoptosis in endothelial cells.
Ombrabulin is an antitubulin vascular disrupting agent.
