Pinosylvin, a pre-infectious stilbenoid toxin, is used to study its properties as a fungitoxin and potential therapeutic agent. Pinosylvin monomethyl ether, a methylated derivative of pinosylvin, may be used as a reference material in the analysis of stibenoid toxins. Pinosylvin monomethyl ether may also be used as a representative stilbene to study its biological actions and therapeutic value in processes such as cell survival, apoptosis and cell mobility.
