Two reverse-prenylated indole alkaloids, deoxybrevianamide E and 6-hydroxydeoxybrevianamide E, are proposed as biosynthetic precursors for advanced metabolites isolated from the marine-derived Aspergillus sp. In order to uncover the role of the alkaloids in the biosynthetic pathway, the feeding experiments of the (13)C-[(15)N]-labeled deoxybrevianamide E and 6-hydroxydeoxybrevianamide E were performed to afford the metabolites, which were produced by oxidation and successive pinacol-type rearrangement of the isoprenyl units.
两种反式异戊烯基化吲哚生物碱,脱氧短裸壳菌素E和6-羟基脱氧短裸壳菌素E,被认为是从海洋来源的曲霉属真菌中分离出的高级代谢产物的生物合成前体。为了揭示这些生物碱在生物合成途径中的作用,进行了(13)C-[(15)N]标记的脱氧短裸壳菌素E和6-羟基脱氧短裸壳菌素E的饲喂实验,以得到由异戊烯基单元氧化和连续频哪醇型重排产生的代谢产物。
