Four new β-carboline-based metabolites, didemnolines A-D (1–4), were isolated along with eudistomin O (5), β-carboline (6), and 2-(2′,4′-dibromophenoxy)-3,5-dibromophenol (7) from an ascidian of the genus Didemnum, collected near the island of Rota, Northern Mariana Islands. These new β-carboline-based metabolites differ from most previously isolated compounds in that they are substituted at the N9
分离了四种新的基于β-咔啉的代谢物,ditemnolines AD(1-4),以及eudistomin O(5),β-carboline(6)和2-(2',4'-dibromophenoxy)-3,5 -dibromophenol(7)来自Didemnum属的海鞘,收集于北马里亚纳群岛罗塔岛附近。这些新的基于β-咔啉的代谢物与大多数先前分离的化合物不同,因为它们在β-咔啉环的N9位置而不是C1位置被取代。
