Piceatannol, 10 mg

trans-3,3′,4,5′-Tetrahydroxystilbene, 4-[(1E)-2-(3,5-Dihydroxyphenyl)ethenyl]-1,2-benzenediol

Syk/ZAP70-specific kinase inhibitor

More details


Piceatannol has been reported as a Syk/ZAP70-specific kinase inhibitor, which selectively inhibits the tyrosine phosphorylation of STAT3 and STAT5, but not of STAT1 and STAT2. It also suppresses NF-kappaB activation induced by various inflammatory agents through inhibition of IkappaBalpha kinase and p65 phosphorylation.

Long Term Storage:  -20°C
Appearance:  Yellow to off-white solid.
