This reports the synthesis and in vitro antimicrobial properties of a series of 2-thioether-linked quinolonyl-carbapenems. Although the title compounds exhibited broad spectrum activity, the MICs were generally higher than those observed for selected benchmark carbapenems, quinolonyl-penems, and quinolones. Enzyme assays suggested that the title compounds are potent inhibitors of penicillin binding proteins and inefficient inhibitors of bacterial DNA-gyrase. Uptake studies indicated that the new compounds are not substrates for the norA encoded quinolone efflux pump.
本文报道了一系列2-硫醚连接的喹诺酮基碳青霉烯类化合物的合成及其体外抗菌性能。尽管标题化合物表现出广谱活性，但其最低抑菌浓度（MIC）通常高于所选基准碳青霉烯类、喹诺酮基青霉烯类和喹诺酮类化合物所观察到的MIC。酶分析表明，标题化合物是青霉素结合蛋白的有效抑制剂，而对细菌DNA促旋酶的抑制作用较弱。摄取研究表明，新化合物不是norA编码的喹诺酮外排泵的底物。
