Abstract

Following the characterization of theonellapeptolides Ia-Ie (2-6), another new tridecapeptide lactone named theonellapeptolide IId (1) was isolated from the Okinawan marine sponge Theonella swinhoei. The structure of 1 has been determined on the bases of chemical and physicochemical examinations which included an HPLC-CD combined analysis of the amino acid composition. Theonellapeptolide IId (1) prevented fertilization of the sea urchin Hemicentrotus pulcherrimus at the concentration of 25 micrograms/ml or greater but did not affect early embryonic development of fertilized eggs up to the gastrula stage.

摘要

在对西奥内拉肽Ia - Ie(2 - 6)进行表征之后,从冲绳海洋海绵斯氏海绵(Theonella swinhoei)中分离出了另一种名为西奥内拉肽IId(1)的新型十三肽内酯。通过化学和物理化学检测确定了1的结构,这些检测包括对氨基酸组成的高效液相色谱 - 圆二色光谱联用分析。西奥内拉肽IId(1)在浓度为25微克/毫升或更高时可阻止海胆光棘球海胆(Hemicentrotus pulcherrimus)受精,但对受精卵直至原肠胚阶段的早期胚胎发育没有影响。
