稀土-组氨酸-苯骈咪唑三元配合物的合成及其生物活性

Synthesis of Rare Earth Complexes with L-histidine and Benzimidazole and Their Bioactivity

在甲醇中合成了3种稀土-组氨酸-苯骈咪唑配合物Re(H is)m(B IM)(C lO4)3.nH2O(Re=La,m=3,n=6;Re=Nd,Y,m=2,n=8),其结构经UV,IR,TG-DTA,摩尔电导,化学分析和元素分析表征。生物活性实验表明:配合物对大肠杆菌、金黄色葡萄球菌和霉菌均有不同程度的抑菌作用,且菌液浓度越低,配合物的抑菌效果越好。

Three complexes of rare earth （Re） with L-histidine and benzimidazole, Re （ His ） m （ BIM ） （ClO4） 3 · nH2O（ Re = La, m = 3, n = 6 ; Re = Nd, Y, m = 2, n = 8）, were synthesized in methanol. The complexes were characterized by UV, IR, TG-DTA, molar conductivity, capacity analysis and elemental analysis. Bioactivity experiments showed that the complexes exhibited bacteriostasis activities for escherichia coli, staphlococcus aureus and mould.
