to that followed by the "blackleg" fungus (Phoma lingam/Leptosphaeria maculans). In addition, it was established that tetradeuterated brassinin was incorporated into the phytoalexin brassilexin in B. juncea and B. rapa. On the other hand, the tetradeuterated indole glucosinolate glucobrassicin was not incorporated into brassinin, although the chemical structures of brassinins and indole glucosinolates
十字花科植物抗毒素芸苔素和环芸苔素以及相关化合物 indole-3-carboxaldehyde、glucobrassicin 和 indole-3-acetaldoxime 的代谢在芥菜和 B. rapa 的各种植物组织中进行了研究。用芸苔素进行的代谢研究表明,芥菜的茎通过 indole-3-carboxaldehyde 将放射性标记的芸苔素代谢为 indole-3-乙酸,这是一种类似于“黑腿病”真菌(Phoma lingam/Leptosphaeria maculans)的解毒途径。此外,已确定四氘化芸苔素被掺入芥菜和油菜中的植物抗毒素芸苔素中。另一方面,四氘代吲哚芥子油苷葡糖苷未掺入芸苔素中,尽管芸苔素和吲哚硫代葡萄糖苷的化学结构表明相互关联的生物发生。重要的是,四氘代吲哚-3-乙醛肟是植物抗毒素芸苔素、芸苔素和螺芸苔素的有效前体。在芥菜和芥菜组织中的诱导实验表明,indole-3-acetonitrile
