生物活性

Piceatannol is a well-known Syk inhibitor and reduces the expression of iNOS induced by TNF. Piceatannol is an effective agent for research of acute lung injury (ALI). Piceatannol is a naturally occurring polyphenolic stilbene found in various fruits and vegetables and exhibits anticancer and anti-inflammatory properties. Piceatannol induces apoptosis in DLBCL cell lines. Piceatannol induces autophagy and apoptosis in MOLT-4 human leukemia cells.

体外研究

Piceatannol is a resveratrol metabolite.
SYK inhibitor Piceatannol (3.125, 6.25, 12.5, 25, and 50 μM; 72 hours) inhibits cell growth of six diffuse large B cell lymphomas (DLBCL) cell lines (SUDHL-6, U2392,DOHH2,Karpas 422, VAL, OCI Ly19) with IC50s of 18 μM, 25 μM, 37 μM, 48 μM, >50 μM and >50 μM, respectively.

Cell Cytotoxicity Assay

Cell Line: Six DLBCL cell lines (Karpas 422, VAL, SUDHL-6, OCI Ly19, U2392 and DOHH2)
Concentration: 3.125, 6.25, 12.5, 25, and 50 μM
Incubation Time: 72 hours
