Novel bacterial topoisomerase inhibitors (NBTIs) are the newest members of gyrase inhibitor broad-spectrum antibacterial agents, represented by the most advanced member, gepotidacin, a 4-amino-piperidine linked NBTI, which is undergoing phase III clinical trials for treatment of urinary tract infections (UTI). We have extensively reported studies on oxabicyclooctane linked NBTIs, including AM-8722
新型细菌拓扑异构酶抑制剂(NBTI)是旋转酶抑制剂广谱抗菌药的最新成员,以最先进的成员吉泊达星(4-氨基哌啶连接的NBTI)为代表,目前正在进行治疗尿路感染的Ⅲ期临床试验。感染(尿路感染)。我们广泛报道了有关氧杂双环辛烷连接的 NBTI 的研究,包括 AM-8722。本研究总结了 AM-8722 的结构活性关系 (SAR),从而鉴定了基于 7-氟-1-氰甲基-1,5-萘啶-2-酮的 NBTI(16,AM-8888),其效力和谱图得到了改进( MIC 值为 0.016–4 μg/mL),铜绿假单胞菌是最不敏感的菌株(MIC 4 μg/mL)。
