Three new bioactive marine diterpenoids, stolonidiol (1), stolonidiol monoacetae (2), and claenone (3), were isolated from Japanese soft coral of the genus Clavularia. The structures of these diterpenoids were elucidated on the basis of spectroscopic data including two-dimensional nuclear magnetic resonance, chemical reactions, and/or X-ray crystallographic analysis. Compounds 1 and 2 showed a strong cytotoxic activity against P388 leukemia cells, and 3 was inhibitory in the fertilized sea urchin egg assay.
从日本软珊瑚属(Clavularia)中分离出了三种新的具有生物活性的海洋二萜类化合物:匍匐茎二醇(1)、匍匐茎二醇单乙酸酯(2)和匍匐茎二酮(3)。根据光谱数据,包括二维核磁共振、化学反应和/或 X 射线晶体分析,阐明了这些二萜类化合物的结构。化合物 1 和 2 对 P388 白血病细胞具有很强的细胞毒性,而化合物 3 在海胆受精卵试验中具有抑制作用。
