conformation analysis and synthesized by applying a conventional coupling reaction of the quinolone nuclei with new piperidine side chains. These compounds were tested in MIC assays and found to be highly potent against Gram-positive and Gram-negative organisms. In particular, the new compounds exhibited high activity against the resistant pathogens Staphylococcus aureus (MRCR) and Streptococcus pneumoniae
通过使用低能构象分析设计了带有(3S)-氨基-(4R)-乙基哌啶的新型喹诺酮类抗菌剂,并通过常规的喹诺酮核与新哌啶侧链的偶联反应合成了喹诺酮类抗菌剂。这些化合物在MIC分析中进行了测试,被发现对革兰氏阳性和革兰氏阴性生物非常有效。特别是,这些新化合物对耐药性病原体金黄色葡萄球菌(MRCR)和肺炎链球菌(PR)表现出高活性。重要的是,当将(3S)-氨基-(4R)-乙基哌啶基喹诺酮与在C-7位置共享相同喹诺酮核但侧链不同的喹诺酮进行比较时,新喹诺酮对革兰氏阳性生物表现出优异的活性,包括抗性病原体。
