From: Biosynthesis of resveratrol derivatives and evaluation of their anti-inflammatory activity
Anti-inflammatory activity of resveratrol derivatives. a Relative cell viability after treatment with lipopolysaccharide (LPS) and resveratrol derivatives. b Level of released interleukin 6 (IL-6) after LPS treatment in the presence of resveratrol derivatives. c Level of tumor necrosis factor α (TNF- α) after LPS treatment in the presence of resveratrol derivatives. Control (Cont), no treatment; 1, resveratrol; 2, 4-methoxyresveratrol; 3, pterostilbene; 4, isorhapontigenin; 5, rhapontigenin; 6, piceatannol. All the compounds were used at a concentration of 10 µM. ns, *, **, and *** indicates not significant, p < 0.05, p < 0.01, and p < 0.001, respectively
