Abstract

Six furanosesquiterpenes have been isolated from an Australian nudibranch, Ceratosoma brevicaudatum, and their structures were determined by spectral analysis. The metabolites include the known terpenes dehydrodendrolasin [1], dehydrolasiosperman [3], and thiofurodysinin acetate [7]. The remaining metabolites were determined to be an unreported cis isomer 2 of dehydrodendrolasin, (methylthio) furodysinin [4], and dithiofurodysinin disulfide [5], derivatives of thiofurodysinin acetate that had been isolated earlier from a sponge. 13C-nmr data were obtained for all compounds.

摘要

已从澳大利亚裸鳃亚目动物短尾角海牛（Ceratosoma brevicaudatum）中分离出六种呋喃倍半萜，并通过光谱分析确定了它们的结构。这些代谢产物包括已知的萜类化合物脱氢树兰素[1]、脱氢拉西奥斯佩曼[3]和硫代呋喃地辛乙酸酯[7]。其余的代谢产物被确定为脱氢树兰素的一种未报道的顺式异构体2、（甲硫基）呋喃地辛[4]和二硫代呋喃地辛二硫化物[5]，它们是硫代呋喃地辛乙酸酯的衍生物，该衍生物 earlier 从一种海绵中分离得到。获得了所有化合物的13C-核磁共振数据。
