A new eunicellin diterpenoid, cladieunicellin I (1), and a new natural eunicellin, litophynin I diacetate (2), were isolated from a Formosan soft coral identified as Cladiella sp. The structures of eunicellins 1 and 2 were elucidated by spectroscopic methods and by comparison of the spectral data with those of related analogues. Eunicellin 1 exhibited significant cytotoxicity toward the DLD-1 human colorectal adenocarcinoma cells.
从台湾产软珊瑚 Cladiella sp. 中分离得到了两个新的海鞘素二萜类化合物,分别为 cladieunicellin I(1)和 litophynin I 二乙酸酯(2)。通过波谱方法并结合与相关类似物的光谱数据比较,阐明了海鞘素 1 和 2 的结构。化合物 1 对人结直肠腺癌细胞 DLD-1 表现出显著的细胞毒性。
