雷公藤(Tripterygium wilfordii)的临床应用艾德提取物提供了三种新的二萜类化合物:3 β,19-二羟基松香-8,11,13-三烯(triptobenzene L)(1); 12,19-二羟基-3-氧代松香-8,11,13-三烯(triptobenzene M)(2);和19-羟基-3,7-二氧代松香-8,11,13-三烯(triptobenzene N)(3)-沿着14种已知的二萜类化合物。1 - 3的结构是在光谱研究的基础上确定的。在已知化合物中,雷公藤内酯醇(4)的C-4位的立体化学被重新指定。雷公藤甲素(8)和13-表-甘露酰氧-18-酸(9)对细胞因子的产生有显著的抑制作用。
A clinically us ed extract of Tripterygium wilfordii afforded three new diterpenoids-3 beta,19-dihydroxyabieta-8,11,13-triene (triptobenzene L) (1); 12,19-dihydroxy-3-oxoabieta-8,11,13-triene (triptobenzene M) (2); and 19-hydroxy-3,7-dioxo-abieta-8,11,13-triene (triptobenzene N) (3)-along with 14 known diterpenoids. The structures of 1-3 were established on the basis of spectroscopic studies. Of the known compounds, the stereochemistry at C-4 of triptonediol (4) was reassigned. Tripterifordin (8) and 13-epi-manoyl oxide-18-oic acid (9) showed significant inhibitory effects on cytokine production.
