We report improved adjuvant compounds that have an aryl 2-aminoimidazole structure for macrolide potentiation against a virulent strain of gram-negative bacteria, AB5075. Compounds were discovered to retain significant adjuvant activity at 10 μM, lowering the minimum inhibitory concentration (MIC) of clarithromycin (CLR) from 8-fold to 128-fold or greater. 2-Aminoimidazole compounds linked to aryl groups via either an amide or urea linker showed significantly improved activity over control compounds.
我们报告了一种改进的辅助化合物,其具有芳基2-氨基咪唑结构,可以增强大环内酯类抗生素对革兰氏阴性细菌AB5075的作用。发现这些化合物在10微摩尔浓度下仍保持显著的辅助活性,将克拉霉素(CLR)的最低抑制浓度(MIC)从8倍降低到128倍或更高。通过酰胺或脲连接物连接到芳基的2-氨基咪唑化合物显示出明显优于对照化合物的活性。
