Obtustatin triacetate
Based on 4 publication(s) in Google Scholar
Obtustatin triacetate is a 41-residue non-RGD disintegrin. Obtustatin triacetate can be isolated from the venom of Vipera lebetina obtusa. Obtustatin triacetate is a potent and selective inhibitor of integrin α1β1 adhesion to type IV collagen. Obtustatin triacetate inhibits angiogenesis and may be used in cancer research.
