The synthesis of Cu(II) complexes derived from Schiff base ligands obtainedby the condensation of 2-hydroxybenzaldehyde or terephtalic aldehyde with 4-amino-antipyrine (4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one) is presented. The newlyprepared compounds were characterized by 1H-NMR, UV-VIS, IR and ESRspectroscopy. The determination of the antimicrobial activity of the ligands and of thecomplexes was carried out on samples of Escherichia coli, Klebsiella pneumoniae,Acinetobacter boumanii, Pseudomonas aeruginosa, Staphylococcus aureus and Candidasp. The qualitative and quantitative antimicrobial activity test results proved that all theprepared complexes are very active, especially against samples of Ps. aeruginosa, A.Boumanii, E. coli and S. aureus.
本文介绍了通过 2-羟基苯甲醛或三苯乙烯醛与 4-氨基安替比林(4-氨基-2,3-二甲基-1-苯基-3-吡唑啉-5-酮)缩合得到的希夫碱配体的 Cu(II) 复合物的合成。通过 1H-NMR、UV-VIS、IR 和 ESR 光谱对新制备的化合物进行了表征。在大肠杆菌、肺炎克雷伯氏菌、鲍曼不动杆菌、铜绿假单胞菌、金黄色葡萄球菌和 Candidasp 样品上测定了配体和复合物的抗菌活性。定性和定量抗菌活性测试结果证明,所有制备的复合物都具有很高的活性,尤其是对铜绿假单胞菌、布氏奈瑟菌、大肠杆菌和金黄色葡萄球菌样品。
