tackle infections caused by multidrug-resistant (MDR) pathogens. During the course of our wider efforts to discover and exploit novel mechanism of action antibacterials, we have identified a novel series of isothiazolone based inhibitors of bacterial type II topoisomerase. Compounds from the class displayed excellent activity against both Gram-positive and Gram-negative bacteria with encouraging activity
对于解决由多重耐药性(MDR)病原体引起的感染的新型抗菌药物,迫切需要满足医疗需求。在我们更广泛的发现和利用新的作用机理的过程中,我们发现了一系列基于异噻唑酮的新型细菌II型拓扑异构酶抑制剂。与环丙沙星相比,该类化合物对革兰氏阳性菌和革兰氏阴性菌均表现出优异的活性,对一组MDR临床大肠杆菌分离株具有令人鼓舞的活性。代表性化合物还显示出有希望的体外安全性。
