human pathogenic bacteria and fungi has become a global health problem. Based on previous reports of 4-(salicylideneamino)benzoic acids, we designed, synthesised and evaluated their me-too analogues as potential antimicrobial agents. Forty imines derived from substituted salicylaldehydes and aminobenzoic acids, 4-aminobenzoic acid esters and 4-amino-N-phenylbenzamide were designed using molecular hybridization
人类病原性细菌和真菌的抵抗力增强已成为全球性的健康问题。根据先前关于4-(水杨亚氨基氨基)苯甲酸的报道,我们设计,合成和评估了它们的中型类似物作为潜在的抗菌剂。40个亚胺衍生自取代的水杨醛和氨基苯甲酸,4-氨基苯甲酸酯和4-氨基-N使用分子杂交和前药策略设计了苯基苯甲酰胺。以高收率合成目标化合物并通过光谱方法表征。他们针对一组革兰氏阳性和革兰氏阴性细菌,分枝杆菌,酵母菌和霉菌进行了调查。测试了活性最高的亚胺,以确定它们在HepG2细胞中的细胞毒性和选择性。基于二卤代水杨醛的衍生物显示出有效的广谱抗菌特性,特别是针对革兰氏阳性细菌,包括耐甲氧西林的金黄色葡萄球菌(最低抑菌浓度,MIC从7.81 µM)和粪肠球菌(MIC≥15.62µM),酵母菌(MIC从MIC 7.81 µM)和叉毛癣菌模具(MIC≥3.90µM)。4-[(2-羟基-3,5-二碘亚苄基)氨基]苯甲酸甲酯4h表现出优异的体外活
