摘要:

本文发展了一种制备胍基取代氨基糖苷衍生物的新方法。用游离胍与苄氧羰酰基保护的氨基糖苷反应, 可以高收率地得到胍羰基取代产物。反应中分离得到了甲氧羰酰基取代的中间体, 并对反应机理进行了推测。应用这种方法, 成功制备了六个氨基全部和部分衍生的胍甲酰基氨基糖苷类衍生物。

关键词: 氨基糖苷, 苄氧羰酰基, 取代, 胍甲酰基, 抗菌活性

Abstract:

A novel method to prepare guanidine substituted aminoglycoside derivatives was developed. Free guanidine reacted with Cbz-protected aminoglycosides to produce guanidinylcarbonyl substituted derivatives. A methoxycarbonyl-protected intermediate was isolated, and the mechanism of guanidinylcarbonyl modification was proposed. With this method, six per- or part- guanidylcarbonyl substituted aminoglycosides were successfully obtained in good yields. Their in vitro antibacterial activities were essayed.

Key words: Aminoglycoside, Cbz, Substituted, Guanidine, Antibacterial activities
