喹诺酮类抗菌药抗菌谱广,在临床上广泛应用于各种感染的治疗。喹诺酮类药物可通过阻断拓扑酶的生理功能继而干扰细菌的复制,从而起到抗菌的作用。也正是由于其广泛应用,近年来此类药物的耐药现象严重,且机制多样。综述了喹诺酮类药物的作用机制、耐药机制及其研究进展。

[Abstract]
Quinolones have potential and broad antimicrobial activity on gram-positive and -negative bacteria in clinic, respectively. They could interfere the duplication of bacteria by blocking the physiologic function of DNA gyrase and DNA topoisomerase IV. So quinolones have been used worldwide against a variety of infections. As a result of their frequent use, bacterial resistance to quinolones has gradually developed and limited their therapeutic efficacy in infections. This article reviews the antibacterial and resistance mechanisms of quinolone based on the recent research advances.
