Hazard Information

Chemical Properties

yellow to golden or green crystalline powder

Uses

A human metabolite of Resveratrol (R150000).

Definition

ChEBI: A stilbenol that is trans-stilbene in which one of the phenyl groups is substituted by hydroxy groups at positions 3 and 4, while the other phenyl group is substituted by hydroxy groups at positions 3 and 5.

Biological Activity

Anti-inflammatory, immunomodulatory and antiproliferative agent. Inhibits p56 lck and syk protein tyrosine kinases and inhibits TNF-induced NF- κ B activation and gene expression. Synthesis results from conversion of resveratrol (5-[(1E)-2-(4-Hydroxyphenyl)ethenyl]-1,3,benzenediol ) by cytochrome P450 1B1.

General Description

A cell-permeable, substrate competitive and reversible plant metabolite that inhibits the activity of rat liver protein kinase A catalytic subunit (IC₅₀ = 3 μM), PKC (IC₅₀ = 8 μM), MLCK (IC₅₀ = 12 μM). In RBL-2H3 cells, the selective inhibition of Syk by piceatannol results in inhibition of FceR1-mediated signaling. Also inhibits wheat embryo Ca²⁺-dependent protein kinase (CDPK) (IC₅₀ = 19 μM), and p72^syk (IC₅₀ = 10 μM), a non-receptor tyrosine kinase, relative to Lyn in isolated enzyme preparations. Also possesses anti-leukemic properties. Reported to activate sirtuins and promote the survival of eukaryotic cells.

Biochem/physiol Actions

Cell permeable: yes

storage

+4°C
