Biological Activity for Piceatannol
Piceatannol is an anti-inflammatory, immunomodulatory and antiproliferative agent. Inhibits p56lck and syk protein tyrosine kinases and inhibits TNF-induced NF-κB activation and gene expression. Synthesis results from conversion of resveratrol (Cat. No. 1418) by cytochrome P450 1B1.
