CLR signaling inhibitor - Syk inhibitor

Piceatannol (3, 4’, 3’, 5-trans-trihydroxystilbene) is a resveratrol analogue with antioxidant, anticancer and anti-inflammatory activities.

Piceatannol has been shown to inhibit NF-κB and JAK-1, two key players in the immune response. Piceatannol also inhibits Syk which plays a crucial role in the signaling pathway of C-type lectin receptors [1].
