A series of novel pyridone conjugated monobactams with various substituents at the (4) position were synthesized and evaluated for their antibacterial activities against a panel of multidrug-resistant (MDR) Gram-negative bacteria in vitro. Compounds 46d, 54 and 75e displayed good to moderate activities against P. aeruginosa, among which the activity of 75e against P. aeruginosa was comparable to that
合成了一系列在(4)位置具有多个取代基的新型吡啶酮共轭单bactams,并评估了它们对一组耐多药(MDR)革兰氏阴性细菌的体外抗菌活性。化合物46d,54和75e对铜绿假单胞菌显示出良好至中等的活性,其中75e对铜绿假单胞菌的活性与铁限制条件下的BAL30072相当。化合物35,46D,54,56A,56C和56D表现出对大肠杆菌和肺炎克雷伯菌的良好至优异的抗菌活性,与BAL30072相当或优于BAL30072。进一步评估了体外肝微粒体的稳定性,结果表明化合物35、46d和54在人肝微粒体中具有代谢稳定性。
