organisms have re-emerged as the major hospital pathogens, which make the unmet medical needs for antibacterial therapy even worse. In searching for potent agents against Gram-positive pathogens, novel 7-(substituted)-aminomethyl-quinolone-3-carboxylic acids were designed, synthesized, and evaluated for their antibacterial activities in vitro. Many 7-monoarylaminomethyl derivatives exhibited high potency against
革兰氏阳性生物已重新成为医院的主要病原体,这使得未得到满足的抗菌治疗的医疗需求更加严重。在寻找针对革兰氏阳性病原体的有效药物时,设计,合成了新型7-(取代)-氨基甲基-喹诺酮-3-羧酸,并对其体外抗菌活性进行了评估。与参考药物:万古霉素和帕珠沙星相比,许多7-单芳基氨基甲基衍生物对革兰氏阳性生物均显示出高效力。另外,一些7-单烷基氨基甲基衍生物对革兰氏阳性和革兰氏阴性生物均表现出良好的活性。
