从云南三宝木(Trigonostemon thyrsoideum)的茎中分离得到了4种高度氧化的瑞香烷型二萜类化合物,即trigonothyrins D - G(1 - 4),并通过大量的光谱研究确定了它们的结构。对化合物1、3和4进行了抗HIV - 1活性评估,其中,3显示出活性,其半数有效浓度(EC50)值为0.13μg/mL,治疗指数(TI)为75.1。(C)2010爱思唯尔有限公司。保留所有权利。
Four highly oxygenated daphnane diterpenoids, trigonothyrins D-G (1-4), were isolated from the stems of Trigonostemon thyrsoideum, and their structures were elucidated on the basis of extensive spectroscopic studies. Inhibitory activity against HIV-1 was assessed for compounds 1,3 and 4, wherein, 3 showed activity with an EC50 value of 0.13 mu g/mL and a therapeutic index (TI) of 75.1. (C) 2010 Elsevier Ltd.
