he metabolism of analogs of the cruciferous phytoalexin brassinin by the phytopathogenic fungi Phoma lingam (Tode ex Fr.) "virulent" and "avirulent" groups (sexual stage Leptosphaeria maculans (Desm.) Ces. et de Not.) and Alternaria brassicae (Berk.) Sacc. is reported. It was established that each pathogen detoxified methyl tryptamine dithiocarbamate, although yielding different metabolic products
十字花科植物抗毒素芸苔素类似物由植物病原真菌 Phoma lingam (Tode ex Fr.)“有毒”和“无毒”组(有性阶段 Leptosphaeria maculans (Desm.) Ces. et de Not.)和 Alternaria brassicae (Berk) 代谢.) 囊。被报道。已确定每种病原体都能解毒甲基色胺二硫代氨基甲酸酯,尽管产生不同的代谢产物。虽然毒性 P. lingam 的生物转化继续产生甲基 3a-羟基-3,3a,8,8a-四氢吡咯并[2,3-b]indol-1(2H)-yl carbodithioate 和 indole-3-乙酸作为最终产物产品中,无毒的 P. lingam 通过 Nb-乙酰色胺产生吲哚-3-羧酸,而芸苔属植物产生 Nb-乙酰色胺,作为最终产品。此外,为了确定二硫代氨基甲酸酯基团在对抗 P. lingam 和 A. brasicae
