General description
Piceatannol is a natural tetrahydroxystilbene, that is extracted from grapes, red wine and Euphorbia lagascae seeds.
Application
Piceatannol has been used:
- to study its effect on Ataxia-Telangiectasia Mutated (ATM) protein kinase
- as an inhibitor of ZAP-70 (ζ-chain-associated protein kinase 70)
- as an inhibitor of MRP1-mediated 2′,7′-bis-(carboxypropyl)-5(6)-carboxyfluorescein (BCPCF) transport in intact human erythrocytes and inside-out erythrocyte vesicles (IOVs)
Biochem/physiol Actions
Piceatannol is an analog of resveratrol that possess potential anti-oxidant, anti-cancer and anti-inflammatory properties. Picetannol has been shown to interfere with the cytokine signaling pathway, notably in the inhibition of the spleen tyrosine kinase (Syk) and PI3K. It also inhibits the activation of NFκB in human cultured cells, after treatment with several inflammatory agents, through inhibition of IκBα kinase and p65 phosphorylation.

This study investigated the protective effect and the molecular mechanism of piceatannol on hydrogen peroxide (H2O2)-induced retinal pigment epithelium cell (ARPE-19) damage. Piceatannol treatment significantly inhibited H2O2-induced RPE cell death and reactive oxygen species (ROS) generation by 64.4% and 75.0%
