细菌耐药性威胁着目前可用抗生素的效用。利福平是治疗持续性革兰氏阳性感染的基石,由于抗生素靶标 RNA 聚合酶的单点突变,容易产生耐药性。一种规避耐药性的策略是使用由两种共价连接的抗生素实体组成的“混合”抗生素。与使用单独抗生素的联合疗法相比,这些化合物通常具有两个不同的细胞靶标,从而降低了耐药性发展的可能性并可能提供简化的药理学特性。在这里,我们评估了通过连接康乐霉素 A (Kang A)、利福平类似物和一组氟喹诺酮类药物形成的一系列半合成杂合抗生素。Kang A 是一种天然产物抗生素,含有一种新的二甲基琥珀酸部分,为合成杂合抗生素提供了一个新的附着点。我们将通过酸附着点产生的 Kang A 杂合体的活性与在化合物的萘醌环系统上连接的一系列杂合体的活性进行比较。几种杂种通过配对抗生素的作用表现出对抗康 A 抗性细菌的活性,这表明康支架可能为产生有效对抗耐药性感染的抗生素提供新途径。我们将通过酸附着点产生的
