Abstract
In this study, the cytotoxicities and anti-inflammatory activities of five resveratrol derivatives—vitisinol A, (+)-ε-viniferin, (+)-vitisin A, (−)-vitisin B, and (+)-hopeaphenol—isolated from Ampelopsis brevipedunculata var. hancei were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and lipopolysaccharide (LPS)-stimulated RAW264.7 cells, respectively. The result from MTT assay [...] Read more.
In this study, the cytotoxicities and anti-inflammatory activities of five resveratrol derivatives—vitisinol A, (+)-ε-viniferin, (+)-vitisin A, (−)-vitisin B, and (+)-hopeaphenol—isolated from Ampelopsis brevipedunculata var. hancei were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and lipopolysaccharide (LPS)-stimulated RAW264.7 cells, respectively. The result from MTT assay analysis indicated that vitisinol A has lower cytotoxicity than the other four well-known oligostilbenes. In the presence of vitisinol A (5 μM), the significant reduction of inflammation product (nitric oxide, NO) in LPS-induced RAW264.7 cells was measured using Griess reaction assay. In addition, the under-expressed inflammation factors cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in LPS-induced RAW264.7 cells monitored by Western blotting simultaneously suggested that vitisinol A has higher anti-inflammatory effect compared with other resveratrol derivatives. Finally, the anti-inflammatory effect of vitisinol A was further demonstrated on 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced ear edema in mice. As a preliminary functional evaluation of natural product, the anti-inflammatory effect of vitisinol A is the first to be examined and reported by this study. Full article
