The skin of the Notaspidea mollusc Pleurobranchus testudinarius contains a very unusual triterpenoid, testudinariol-A (1), which is also the main liposoluble component of the defensive mucous secretion. The structure, and the absolute stereochemistry, of 1 has been assigned on the basis of extensive spectral and chemical studies. The structural work on a minor co-occurring metabolite, testudinariol-B
Notaspidea软体动物Pleurobranchus testudinarius的皮肤含有非常不寻常的三萜类化合物,testudinariol-A(1),它也是防御性粘液分泌的主要脂溶性成分。在广泛的光谱和化学研究的基础上,确定了1的结构和绝对立体化学。少量共生代谢产物testudinariol-B(2)的结构工作导致C-10的差向异构体1。
