A survey of individual specimens of northern Papua New Guinea derived Cacospongia mycofijiensis has yielded novel sesquiterpenes, aignopsanoic acid A (1), methyl aignopsanoate A (2), and isoaignopsanoic acid A (3). The structures and absolute configurations of 1-3 were established using NMR data, X-ray crystallography results, and an analysis of CD properties. Two of these metabolites, 1 and 2, were moderately active against Trypanosoma brucei, the parasite responsible for sleeping sickness.
对源自巴布亚新几内亚北部的斐济海绵状霉菌个体标本进行的一项调查,得到了新的倍半萜类化合物,即斐济海绵酸A(1)、斐济海绵酸甲酯A(2)和异斐济海绵酸A(3)。利用核磁共振数据、X射线晶体学结果以及圆二色性性质分析确定了1-3的结构和绝对构型。这些代谢产物中的两种,即1和2,对导致昏睡病的寄生虫布氏锥虫具有中等活性。
