Identification of cytotoxic and anti-inflammatory constituents from the bark of Toxicodendron vernicifluum (Stokes) F.A. Barkley.[Pubmed:25582488]
J Ethnopharmacol. 2015 Mar 13;162:231-7.
ETHNOPHARMACOLOGICAL RELEVANCE: Toxicodendron vernicifluum (Stokes) F.A. Barkley (Anacardiaceae) has traditionally been used as a food supplement and in traditional herbal medicine to treat inflammatory diseases and cancers for centuries in Korea. This study was designed to isolate the bioactive constituents from the ethanol extract of Toxicodendron vernicifluum bark and evaluate their cytotoxic and anti-inflammatory activities. MATERIAL AND METHODS: Bioassay-guided fractionation and chemical investigation of the ethanol extract of Toxicodendron vernicifluum bark resulted in the isolation and identification of three new polyphenols (1-3) and six flavonoids (4-9). The structures of the isolated compounds were elucidated by spectroscopic analysis, including 1D and 2D nuclear magnetic resonance (NMR) ((1)H, (13)C, COSY, HMQC and HMBC experiments), and high resolution (HR)-mass spectrometry, and their absolute configurations were further confirmed by chemical methods and circular dichroism (CD) data analysis. Compounds 1-9 were evaluated for their antiproliferative activities against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15), and anti-inflammatory activities by measuring nitric oxide (NO) levels in the medium of murine microglia BV-2 cells. RESULTS: The isolated compounds were characterized as in the following: three new polyphenols, rhusopolyphenols G-I (1-3) and six flavonoids including two aurones, 2-benzyl-2,3',4',6-tetrahydroxybenzo[b]furan-3(2H)-one (4), sulfuretin (5), two dihydroflavonols, (+)-(2S,3R)-fustin (6), (+)-Epitaxifolin (7), one chalcone, butein (8), and one flavonol, fisetin (9). The published NMR assignments of 4 were corrected by the detailed analysis of spectroscopic data in this study. Among the tested compounds, compounds 4-9 showed antiproliferative activity against the tested cells, with IC50 values of 4.78-28.89 muM. Compounds 5 and 8 significantly inhibited NO production in lipopolysaccharide (LPS)-stimulated BV-2 cells with IC50 values of 23.37 and 11.68 muM, respectively. CONCLUSIONS: Polyphenols including flavonoids were one of the main constituents of Toxicodendron vernicifluum bark, and activities demonstrated by the isolated compounds support the ethnopharmacological use of Toxicodendron vernicifluum as anti-cancer and/or anti-inflammatory agents.
