exhibit potent broadspectrum antibacterial activity. In an effort to optimize this class of compounds for the treatment of C. difficile infection (CDI), we have identified cadazolid (9), a first-in-class quinoxolidinone antibiotic, which is a potent inhibitor of C. difficile protein synthesis. In order to achieve narrow-spectrum coverage of clinically most relevant strains without affecting the gut microbiota
艰难梭菌( C. difficile ) 是全球医疗保健相关感染的主要原因之一。对目前可用疗法产生耐药性的菌株发生率不断增加,凸显了对具有新颖作用方式的替代治疗方案的需求。据报道,通过吡咯烷连接体连接至喹诺酮部分的恶唑烷酮(例如化合物1 )表现出有效的广谱抗菌活性。为了优化此类化合物用于治疗艰难梭菌感染 (CDI),我们鉴定出了卡达唑胺 (cadazolid) ( 9 ),这是一种一流的喹诺酮类抗生素,它是艰难梭菌蛋白质合成的有效抑制剂。为了在不影响肠道微生物群的情况下实现临床上最相关菌株的窄谱覆盖,重点是消除针对肠道微生物群共生菌的活性,同时保留致病性艰难梭菌的良好覆盖范围,包括高毒力和流行菌株。
