Two new 11-hydroxyeunicellin diterpenoids, cladieunicellin F (1) and (-)-solenopodin C (2), were isolated from an Indonesian octocoral Cladiella sp. The structures of eunicellins 1 and 2 were established by spectroscopic methods, and eunicellin 2 was found to be an enantiomer of the known eunicellin solenopodin C (3). Eunicellin 2 displayed inhibitory effects on the generation of superoxide anion and the release of elastase by human neutrophils. The previously reported structures of two eunicellin-based compounds, cladielloides A and B, are corrected in this study.
从印度尼西亚八放珊瑚 Cladiella sp. 中分离得到两个新的 11-羟基乌尼烯二萜类化合物 cladieunicellin F(1)和(-)-solenopodin C(2)。通过光谱方法确定了 eunicellins 1 和 2 的结构,并且发现 eunicellin 2 是已知的 eunicellin solenopodin C(3)的对映异构体。Eunicellin 2 对人中性粒细胞产生超氧阴离子和弹性蛋白酶的释放具有抑制作用。本研究更正了先前报道的两种基于 eunicellin 的化合物 cladielloides A 和 B 的结构。
