the structures of the compounds was examined. Antimicrobial activity of the compounds was evaluated against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis. Antifungal activities were reported for Candida albicans. Schiff bases showed considerable antimicrobial activity against S. aureus, S. epidermidis and C. albicans
使用适当的合成路线合成了一系列N-(5-氯-2-羟基苯基)-(3/4 / 5-取代)-水杨醛亚胺(I - XI)。通过FT-IR,UV-Visible,ESI-MS,1 H和13 C NMR光谱技术和分析方法对它们的结构进行了表征。N-(5-氯-2-羟基苯基)-5-溴水杨基醛亚胺(V)的晶体结构在室温下通过X射线衍射测定。研究了熔点与化合物结构之间的关系。评估了该化合物对金黄色葡萄球菌,表皮葡萄球菌,大肠杆菌,肺炎克雷伯菌,铜绿假单胞菌,奇异变形杆菌。据报道,白色念珠菌具有抗真菌活性。席夫碱表现出了相当的抗菌活性对金黄色葡萄球菌,表皮葡萄球菌和Ç。白色的。N-(5-氯-2-羟基苯基)-3-羟基水杨基亚胺(II)具有最广泛和最高的抗菌活性。
