Description générale

Combretastatin A4 belong to the class of colchicinoids compounds.

Application

Combretastatin A4 has been used:
  • as an anti-tubulin agent to determine the effects of isocitrate dehydrogenases (IDH1 and IDH2) proteins in G2/M phase
  • to evaluate the anti-proliferative and pro-apoptotic properties of biphenyl CA4 derivatives in both 2D and 3D cancerous and non-cancerous cell models
  • as a microtubule inhibitor to study its effects on motility of Ascaris suum L3 larvae

Actions biochimiques/physiologiques

Combretastatin A4 is a potent microtubule targeting agent (MTA).
Combretastatin A4 is a vascular disrupting agent (VDA) that targets tumor vasculature to inhibit angiogenesis. It inhibits tubulin polymerization at the colchicine-binding site of beta-tubulin. It has antitumor activity by inhibiting AKT function in human gastric cells. The inhibited AKT activation causes decreased cell proliferation, cell cycle arrest, and reduced in vitro migration/invasiveness and in vivo metastatic ability. Combretastatin A4 is a natural stilbenoid phenol.
