摘要 : Two new polyacetylenes, (2S) (5E, 11E)-tridecadiene-7,9-diyne-1,2,13-triol (1) and (6E, 12E)-3-oxo-tetradecadiene- 8,10-diyne-14-hydroxyl-1-O-beta-D-glucopyranoside (2) along with four known polyacetylenes (3-6), were isolated fro... 展开 Two new polyacetylenes, (2S) (5E, 11E)-tridecadiene-7,9-diyne-1,2,13-triol (1) and (6E, 12E)-3-oxo-tetradecadiene- 8,10-diyne-14-hydroxyl-1-O-beta-D-glucopyranoside (2) along with four known polyacetylenes (3-6), were isolated from the whole plant of Bidens bipinnata L. Their structures were elucidated by spectroscopic data. All compounds were evaluated for their anti-inflammatory activities on lipopolysaccharide (LPS)-induced IL-1 and tumor necrosis factor (TNF-alpha) production in macrophage (RAW264.7) cells and cytotoxic activities on human cervical carcinoma (Hela), human hapetocelluar carcinoma (HepG-2), and human breast carcinoma (MCF-7) cell lines. 收起
