Obtustatin
Obtustatin is a non-RGD disintegrin of 41 residues. Obtustatin can be isolated from Vipera lebetina obtusa venom. Obtustatin is a potent and selective inhibitor of the adhesion of integrin α1β1 to collagen IV. Obtustatin inhibits angiogenesis, and can be used for research of cancer[1][2].
