  Synthesis and Evaluation of the Antimicrobial Activity of Dodecyl trimethyl ammonium and N-(N, N-dimethylamino) Propyl Glucosylamine

  摘要：

  在这项研究中，十二烷基三甲基硫酸铵（DTA）是通过十二烷基胺和硫酸二甲酯之间的季铵化反应获得的（产率：51.5%），而二甲基氨基丙基葡萄糖胺（DAPGA）则是由 D-葡萄糖和 3-二甲基氨基丙基胺先后合成的（产率：93.6%）。这两种化合物都通过核磁共振光谱进行了分析。对它们针对鼠伤寒沙门氏菌、金黄色葡萄球菌和立方镰刀菌的生物活性进行的评估表明，当浓度大于 0.001 10-4 摩尔 mL-1 时，DTA 能显著抑制鼠伤寒沙门氏菌和金黄色葡萄球菌的生长，而 DAPGA 则无效。此外，这两种化合物对毒性真菌立方镰刀菌（Fusarium oxysporum cubens）具有明显的抗真菌活性。
