Off-white crystalline powder

The Uses of PINOSYLVIN

Pinosylvin, a pre-infectious stilbenoid toxin, is used to study its properties as a fungitoxin and therapeutic agent. Pinosylvin is used as a representative stilbene to study its biological actions and therapeutic value in processes such as cell survival, apoptosis and cell mobility.

Definition

ChEBI: Pinosylvin is a stilbenol.

General Description

This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG

Enzyme inhibitor

This trans-stilbene derivative (FW = 212.25 g/mol; CAS 102-61-4; M.P. = 155.5-156°C; low solubility in water), also known as (E)-3,5-stilbenediol and trans-3,5-dihydroxystilbene and named systematically as 5-[(E)-2- phenylethenyl]benzene-1,3-diol, occurs naturally in the hardwood of pine and other woody plants. Pinosylvin exxhibits micromolar Ki values for specific isozymes of stilbene synthase and chalcone synthase. Target(s): chalcone synthase; stilbene synthase; tyrosinase, or monophenol monooxygenase.
