Ten new diterpenes, 1−10, having a dolabellane skeleton were isolated from a Colombian gorgonian coral of the genus Eunicea. Their structures, as well as those of known compounds 11−18, were determined on the basis of spectroscopic analysis and, in some instances, by chemical conversion and X-ray crystallographic analysis. The absolute structure of 7 was established by chemical conversion from 11,
从Eunicea属的哥伦比亚柳珊瑚珊瑚中分离出10 种新的二萜,1 - 10,具有多拉标烷骨架。它们的结构以及已知化合物11 - 18 的结构是在光谱分析的基础上确定的,在某些情况下,通过化学转化和 X 射线晶体学分析确定。7的绝对结构是通过化学转化从11建立的,11是已知绝对结构的共存多标签烷同源物。大多数这些二萜类化合物对原生动物寄生虫恶性疟原虫具有抗疟活性。
