摘要: 通过将新霉胺、卡那霉素A、核糖霉素氨基选择性环氨基甲酸酯保护、羟基胺亲核开环, 合成了一系列脲连接的新霉胺、卡那霉素A、核糖霉素羟基胺衍生物, 并对它们的抗菌活性进行了体外活性筛选, 结果表明衍生物没有明显的抗菌活性, 因此脲连接的氨基糖苷−羟基胺结构不能增加氨基糖苷的抗菌活性。

Abstract:

A series of urea-linked hydroxyl-alkylamine derivatives of aminoglycosides have been obtained by modification of neamine (1), kanamycin (2) and ribostamycin (3) at 1, 6' and 3'' N-sites, respectively, through selective cyclization and nucleophilic ring-opening of cyclic carbamates. All the products showed no noticeable activity in the antibiotic test in vitro. The result suggests that the urea-linked hydroxyl-alkylamine derivatives of aminoglycosides may not be suitable structures for the enhancement of antibiotic activity.

Key words: Aminoglycoside, Aminoglycoside, Hydroxyl-alkylamine derivative, Hydroxyl-alkylamine derivative, Synthesis, Synthesis, Antibiotic activity, Antibiotic activity
