A new series of perfluoroalkyl-containing quaternary ammonium compounds were prepared and examined for their antibacterial activities. The perfluoroalkyl-containing quaternary ammonium salts mainly exhibited excellent antibacterial activity for the Gram-positive strain such as Staphylococcus aureus, the MIC (minimal inhibitory concentration) values was between 2.5 and 10 μg/mL and the MBC (minimal
制备了一系列新的含全氟烷基的季铵化合物,并检查了它们的抗菌活性。含全氟烷基的季铵盐主要对革兰氏阳性菌株如金黄色葡萄球菌表现出优异的抗菌活性,MIC(最小抑菌浓度)值在2.5和10μg/ mL之间,MBC(最小杀菌浓度)值是20微克/毫升 它们对革兰氏阴性菌株(如大肠杆菌)和真菌(如白色念珠菌)均显示弱活性,MIC值和MBC值约为100μg/ mL。此外,进一步讨论了它们的抗菌活性和结构之间的关系。
