用不同链长的叔胺(二甲基十二烷基胺、二甲基己胺和二甲基丁胺)对聚酰胺胺(PAMAM)(G3)树枝状大分子进行了有效的合成。采用纸片扩散法检测了树枝状大分子铵盐对葡萄球菌和大肠埃希菌的抑菌活性。结果表明,以二甲基十二烷基胺为原料制备的季铵盐对葡萄球菌和大肠埃希菌有较好的抑菌效果。
Poly(amidoamine) (PAMAM) (G3) dendrimer was modified into quaternary ammonium salts using tertiary amines with different chain lengths: dimethyldodecyl amine, dimethylhexyl amine, and dimethylbutyl amine using an efficient synthetic route. The antimicrobial activity of these dendrimer ammonium salts against Staphylococcus and E-coli bacteria was examined using the disc diffusion method. It was found that quaternary ammonium salt prepared with the dimethyldodecyl amine exhibits antimicrobial efficacy against Staphalococus and E.coli bacteria.
