利用1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮(PMBP)和对氨基苯乙酮(PAAP)制备了PMBP缩对氨基苯乙酮(PMBP缩PAAP)及其铜(II)、钴(II)、镍(II)和锌(II) 配合物,根据元素分析、红外、紫外、MS和1H NMR谱表征了结构.利用量子化学和分子力学计算方法对缩合反应的机理进行了探讨,较好地解释了PMBP-PAAP配体的烯胺酮式构型及其配合物的亚胺烯醇式构型.测定了化合物对大肠杆菌和金黄色葡萄球菌的抑制活性,其中以钴(II)和铜配合物(II)的抑菌活性最佳.

关键词: PMBP-PAAP及其配合物, 合成, 结构表征, 机理分析, 抑菌活性.

The ligand prepared from PMBP with p-aminoacetophenone and its Cu(II), Co(II), Ni(II) and Zn(II) complexes have been synthesized and characterized by IR, UV, MS and 1H NMR spectra. The mechanism of thecondensed reaction has been discussed using quantum chemistry and molecular mechanics calculation, which can explain the enamine conformation of the ligand andthe imine-enol conformation of the complexes. The antibacterial activities have been screened for these compounds, among which the Co(II) and Cu(II) complexes have the most intense antibacterial activities.

Key words: PMBP-PAAP and complex, synthesis, structure characterization, mechanism analysis, antibacterial activity
