Rhapontigenin is astilbenoid. It can be isolated fromVitis coignetiae or fromGnetum cleistostachyum.[1]
It shows an action onprostate cancer cells.[2] It has been shown to inhibit the humancytochrome P450 1A1,[3] an enzyme implicated in the biotransformation of a number of carcinogenic and immunotoxic compounds.
Injected in rats, rhapontigenin shows a rapidglucuronidation and a poorbioavailability.[4]
