已分离出两种新的与卡利佩汀相关的无环肽（2 和 3），以及来自海洋海绵 Latrunculia sp. 的卡利佩汀 A-C。采集于瓦努阿图群岛。通过光谱数据阐明了新化合物的总体结构。将 Marfey 分析应用于新衍生物和 callipeltin A (1)，使我们能够修改 callipeltin A 中两个氨基酸单元的构型。(C) 2002 Elsevier Science Ltd。保留所有权利。
Two new callipeltin-related acyclic peptides (2 and 3) have been isolated, together with callipeltins A-C from the marine sponge Latrunculia sp. collected at the Vanuatu Islands. The gross structures of new compounds were elucidated by spectroscopic data. The application of the Marfey's analysis on the new derivatives and on callipeltin A (1), allowed us to revise the configuration of two amino acid units in callipeltin A.
