Two novel diterpenoids, cespitulones A (1) and B (2), were isolated from extracts of the soft coral Cespitularia taeniata. Both compounds possess an unprecedented bicyclo [10.3.1] ring system with C-C bond connections between C-10 and C-20, and between C-20 and C-11. Their structures were elucidated on the basis of extensive spectroscopic analyses. Compound 1 exhibited significant cytotoxicity against human medulloblastoma and colon adenocarcinoma cancer cells.
从软珊瑚带纹团块珊瑚(Cespitularia taeniata)的提取物中分离出两种新型二萜类化合物,团块二萜A(1)和B(2)。这两种化合物都具有前所未有的双环[10.3.1]环系统,在C-10与C-20之间以及C-20与C-11之间存在碳-碳键连接。它们的结构通过广泛的光谱分析得以阐明。化合物1对人髓母细胞瘤和结肠腺癌癌细胞表现出显著的细胞毒性。
