Biochem/physiol Actions

Isorhapontigenin or 4-methoxyresveratrol is a stilbene derivative isolated from a number of plants including Chinese medical herbs Gnetum Cleistostachyum and Iris Domestica (Belamcanda chinensis, leopard lily), and wine grapes. Similarly to resveratrol, isorhapontigenin is a potent antioxidant that attenuates ROS generation. Also, Isorhapontigenin exhibits pro-apoptopic and anti-cancer activities through downregulation of XIAP (X-linked inhibitor of apoptosis protein).
