摘要: 目的 设计、合成红霉素4''-氨基甲酸酯衍生物, 研究其抗菌活性。方法 以阿奇霉素为起始原料, 1,1'-羰基二咪唑处理以及胺解反应、曼尼希反应制备目标化合物, 并以金黄葡萄球菌为试验菌进行体外抗菌活性研究。结果 共合成了9个目标化合物, 其结构经IR13C NMR1H NMR和元素分析得以证实, 经体外抗菌活性试验发现化合物F-3F-4显示较好抗金黄色葡萄球菌活性, 所有化合物无体外杀菌活性。结论 说明吡咯烷基或哌啶基可能有利于提高抗菌活性。

Abstract: Aim To synthesize 4''-carbamate derivatives of erythromycin and test their antibacterial activities in vitro. Methods New erythromycin antibacterial agents containing 4''-carbamate group were designed and synthesized from azithromycin via protection, aminoformylation, amination and deprotection. Their antibacterial activities against Staphylococcus aureus strains were tested. Results Nine compounds were synthesized. Their structures were confirmed by MS, IR, 1H NMR and 13C NMR, and the synthetic condition (reagent ratios) was exploited. Among them, compounds F-3 and F-4 showed strong antibacterial activities against Staphylococcus aureus. But, all compounds did not show bactericidal activity. Discussion The test results showed that piperidinyl or pyrrolidinyl group may be of benefit to enhancing antibacterial activities.

Key words: Erythromycin derivatives, Erythromycin derivatives, synthesis, synthesis, antibacterial activities, antibacterial activities
