Results from the attempted dehydrogenation of thiostrepton with manganese dioxide have not confirmed the presence of a thiazoline system in the antibiotic. Oxidation of thiostrepton with performic acid yielded 2-(1-amino-2-carboxyethyl)thiazole-4-carboxylic acid, the structure of which was proved by its further oxidation to 2-carbamoylthiazole-4-carboxylic acid, and by its reduction to aspartic acid
硫代链霉菌素与二氧化锰尝试脱氢的结果尚未证实抗生素中存在噻唑啉系统。用过甲酸氧化硫代链霉菌素产生2-(1-氨基-2-羧乙基)噻唑-4-羧酸,其结构通过进一步氧化为2-氨基甲酰基噻唑-4-羧酸并被还原为2-氨基甲酰基噻唑-4-羧酸而得到证实。天冬氨酸,丙氨酸和甘氨酸。
