may cause serious infections, such as pneumonia, which can be fatal especially to immunosuppressed individuals. Hospitalized patients are particularly susceptible to antibiotic-resistant infections, which are worsened when caused by resistant Gram-negative pathogens due to there being few therapeutic options available. Thus, this work describes the synthesis and in vitro antimicrobial profile of 7-arylamino-5
病原细菌可能会引起严重的感染,例如肺炎,这可能对致命的免疫系统造成致命影响。住院患者特别容易受到抗生素耐药性感染,当耐药革兰氏阴性病原体引起耐药性感染时,这种情况会恶化,原因是可用的治疗选择很少。因此,这项工作描述了7-芳基氨基-5,8-二氧代-5,8-二氢异喹啉-4-羧酸盐及其卤代氨基醌对革兰氏阳性和革兰氏阴性细菌的合成和体外抗菌特性。有趣的是,这些生物活性物质已显示出对革兰氏阴性致病菌株的有希望的活性。在这些衍生物中,两种非卤代氨基化合物显示出有希望的MIC和MBC值(MIC = MBC = 1-2μgmL -1)对抗两种具有重要临床意义的革兰氏阴性菌株的大肠杆菌ATCC 25922和铜绿假单胞菌ATCC 27853。此外,单溴和二溴氨基醌也可有效防止大肠杆菌的生长(MIC = MBC = 2-4μgmL -1)。该体外血液相容性评价显示低毒性特征在溶血测定中活性aminoquinon
