Huang, Yun-Ting Chang, Hsun-Shuo Wang, Guei-Jane Cheng, Ming-Jen Chen, Chu-Huang Yang, Yi-Jen Chen, Ih-Sheng Anti-inflammatory Endiandric Acid Analogues from the Roots of <i>Beilschmiedia tsangii</i> Bioassay-guided fractionation of roots of <i>Beilschmiedia tsangii</i> led to the isolation of six new endiandric acid analogues: tsangibeilin A (<b>1</b>), tsangibeilin B (<b>2</b>), endiandramide A (<b>3</b>), endiandric acid K (<b>4</b>), endiandric acid L (<b>5</b>), and endiandramide B (<b>6</b>). Also isolated were two new lignans, beilschminol A (<b>7</b>) and tsangin C (<b>8</b>), and six known compounds. The structures of <b>1</b>–<b>8</b> were determined by spectroscopic techniques. Compounds <b>3</b> and <b>6</b> exhibited potent iNOS inhibitory activity, with IC<sub>50</sub> values of 9.59 and 16.40 μM, respectively. endiandric acid analogues;tsangibeilin;endiandramide;IC 50 values;spectroscopic techniques;16.40 μ M;Compounds 3;Beilschmiedia tsangii 2011-09-23
