A3, A14, A15 and B6 exhibited potent antibacterial effect against both clinical drug sensitive and resistant Gram-positive bacteria, and they are 2–8 folds more potent than levofloxacin against Methicillin-resistant staphylococcus epidermidis (MRSE). A significant synergistic effect of these compounds and polymyxin against drug-resistant Gram-negative bacteria, which is similar to PFK-158 was also
由抗生素抗性细菌引起的感染是全世界的主要健康问题。众所周知,PFK-158可以增强多粘菌素的抗菌作用,但其自身的抗菌作用却鲜有讨论。为了研究 PFK-158 及其衍生物的抗菌作用,设计、合成了 PFK-158 和 35 衍生物并评价了它们的抗菌活性。化合物A1、A3、A14、A15和B6对临床药敏和耐药革兰氏阳性菌均表现出强效抗菌作用,对耐甲氧西林表皮葡萄球菌的作用比左氧氟沙星强2-8倍(MRSE)。还观察到这些化合物和多粘菌素对耐药革兰氏阴性菌的显着协同作用,类似于 PFK-158。该结果可为开发抗耐药菌新药提供新的更广阔的前景。
