Combretastatin A-4 is a combretastatin and a stilbenoid. It can be isolated from Combretum caffrum, the Eastern Cape South African bushwillow tree or in Combretum leprosum, the mofumbo, a species found in Brazil.[2][3]
Function
Tubulin represents a potent target in cancer chemotherapy, given its role in cell division. Combretastatin is a naturally occurring well known tubulin polymerization inhibitor. Combretastatin A-4 comes in two stereoisomers (cis (shown top right), and trans); The cis form binds much better to the 'colchicine' site on tubulin to inhibit polymerization.[4]
Derivatives
Combretastatin A-4 is the active component of combretastatin A-4 phosphate, a prodrug designed to damage the vasculature (blood vessels) of cancer tumors causing central necrosis.[citation needed]
A large number of synthetic derivatives have been reported,[5][6] including beta-lactam based compounds.[7]
