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 [13C]2–[15N]-labeled deoxybrevianamide E and 6-hydroxydeoxybrevianamide E were performed to afford the
两种反向异戊二烯化吲哚生物碱 deoxybrevianamide E 和 6-hydroxydeoxybrevianamide E 被提议作为从海洋来源的曲霉属中分离的高级代谢物的生物合成前体。为了揭示生物碱在生物合成途径中的作用,进行了 [ 13 C] 2 – [ 15 N] 标记的脱氧短酰胺 E 和 6-羟基脱氧短酰胺 E的饲养实验,以提供通过氧化产生的代谢物和异戊二烯基单元的连续频哪醇型重排。
