Combretastatin A-1 is a combretastatin and a stilbenoid. It can be found in Combretum caffrum, the Eastern Cape South African Bushwillow tree.[1]
Biological effects in mammals
It is an antiangiogenic agent acting by destabilizing tubulin, which induces cell apoptosis of proliferating endothelial cells.[1]
Derivatives as drugs
Currently designated an orphan drug by the FDA, combretastatin A1 diphosphate (OXi4503 or CA1P) is in Phase I clinical trials for relapsed and refractory acute myeloid leukemia and myelodysplastic syndrome.[2]
