glycoslated macrocyclic antibiotic fidaxomicin (1, tiacumicin B, lipiarmycin A3) displays good to excellent activity against Gram-positive bacteria and was approved for the treatment of Clostridium difficile infections (CDI). Among the main limitations for this compound, its low water solubility impacts further clinical uses. We report on the synthesis of new fidaxomicin derivatives based on structural
糖化大环抗生素非达霉素( 1 、台勾霉素 B、利拉霉素 A3)对革兰氏阳性菌表现出良好至极好的活性,并被批准用于治疗艰难梭菌感染 (CDI)。该化合物的主要限制之一是其低水溶性影响进一步的临床应用。我们报告了基于结构设计并利用天然产物的操作简单的一步无保护基制备方法合成新的非达霉素衍生物。观察到溶解度增加高达 25 倍,同时大部分活性保留。此外,制备的混合抗生素显示出改善的抗生素活性。
