Abstract
A new polymeric pyridinium alkaloid named amphitoxin [2] has been isolated from Amphimedon compressa, and its structure determined by spectroscopic analysis. In laboratory feeding experiments, crude extracts and purified amphitoxin [2] from A. compressa at lower than natural concentration levels effectively deterred feeding of a generalist predatory Caribbean reef fish, Thalassoma bifasciatum.
摘要
一种名为两栖毒素[2]的新型聚合吡啶生物碱已从扁海绵中分离出来，其结构通过光谱分析确定。在实验室喂食实验中，来自扁海绵的粗提物和纯化的两栖毒素[2]在低于自然浓度水平时有效地阻止了一种杂食性加勒比珊瑚礁鱼类双带锦鱼的进食。
