Notoamide E, a short-lived secondary metabolite, has been proposed as a biosynthetic intermediate to several advanced metabolites isolated from Aspergillus versicolor. In order to verify the role of this indole alkaloid along the biosynthetic pathway, synthetic doubly (13)C-labeled notoamide E was fed to Aspergillus versicolor. Analysis of the metabolites showed significant incorporation of notoamide E into the natural products notoamides C and D.
诺托酰胺E是一种寿命短暂的次生代谢产物,已被认为是从杂色曲霉中分离出的几种高级代谢产物的生物合成中间体。为了验证这种吲哚生物碱在生物合成途径中的作用,将合成的双(13)C标记的诺托酰胺E喂给杂色曲霉。对代谢产物的分析表明,诺托酰胺E大量掺入天然产物诺托酰胺C和D中。
