Selective protein tyrosine kinase Syk inhibitor (IC50~10 M). In RBL-2H3 cells the selective inhibition of Syk by piceatannol results in inhibition of Fc R1-mediated signaling. Besides that it works as activator of human deacetylase SIRT1.A natural stilbene and an analogue of Resveratrol (Prod.# R-1014). Besides antioxidative effects, piceatannol exhibits potential anticancer properties as shown by its ability to suppress proliferation of a wide variety of tumor cells, including leukemia, lymphoma; cancers of the breast, prostate, colon and melanoma. Also inhibits JAK-1 and Syk kinase; blocks adipogenesis of 3T3-L1 preadipocytes in a dose-dependent manner. Originally isolated from Euphorbia lagascae.
