Combretastatin A-4

A synthetic Combretum caffrum-derived cell-permeable stilbenoid phenol that competes with colchicine (Cat No. 234115 ) tubulin binding (by 96.4% at equal molar concentration; Ki = 1.1 µM) and interferes with tubulin polymerization (IC₅₀ = 2-3 µM) as well as cellular microtubule assembly. In addition to its antimitotic and in vitro cancer growth inhibition activity (IC₅₀ = 7 nM in L1210 cultures), CA4 also acts as an antivascular agent and effectively induces tumor cell necrosis in vivo by targeting endothelial cytoskeleton.
