软珊瑚Clavularia属中含有不少结构新颖或者具有生理活性的化合物。作者从软珊瑚Clavularia viridis中发现了8个新二萜和一个新甾醇,其中有些具有抗肿瘤活性。在继续对该属软珊瑚的系统研究中,我们研究了Clavularia inflata Schenk,从中分得一个新的榄香烷型倍半萜环内酰胺,命名为Clavulinin(1),此种含有γ-羟基-α,β-丁内酰胺倍半萜的结构很为罕见。 Soft corals Clavularia genus contains many new or physiologically active compounds. The authors identified eight new diterpenes and one neo-sterol from the soft-shelled Clavularia viridis, some of which have anti-tumor activity. In the systematic study of the genus of soft corals, we studied Clavularia inflata Schenk and obtained a new elemene-type sesquiterpene lactone named Clavulinin (1), which contains γ-hydroxy- The structure of α, β-butyrolactam sesquiterpenes is very rare.
