新的19-降海绵烷二萜的分离及结构确定
Separation and Structure Determination of a New 19-nor-Spongian Diterpenoid
【摘要】 从海洋海绵Spongia zimocca aubspecles irregularia中分离到一种新的19-降海绵烷二萜(ZimoclactoneA,1)和胆甾-5,7-二烯-3β-醇,化合物1的化学结构和立体化学通过波谱方法和X射线单晶衍射分析确定,化合物1对P388肿瘤细胞具有中等程度的细胞毒活性
【Abstract】 A new 19-nor-spongian diterpene, zimoclactone A(1) together with a known compound, cholest-5 ,7-dien-3β-ol(2) were isolated from the Spongia zimocca aubspecles irregularia of marine sponge. The structure of compound 1 was determined by spectroscopic methods as well as X-ray diffraction analysis. Compound 1 showed a moderate cytotoxic activity against P388 cell lines.
