We report in this work the preparation and in vitro antimicrobial evaluation of novel amphiphilic aromatic amino alcohols synthesized by reductive amination of 4-alkyloxybenzaldehyde with 2-amino-2-hydroxymethyl-propane-1,3-diol. The antibacterial activity was determined against four standard strains (Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa) and 21
我们在这项工作中报告了新型的两亲性芳族氨基醇的制备和体外抗菌评估,该两亲性芳族氨基醇是通过将4-烷氧基苯甲醛与2-氨基-2-羟甲基丙烷-1,3-二醇进行还原胺化而合成的。抗菌活性针对四个标准株(确定金黄色葡萄球菌,表皮葡萄球菌,大肠埃希氏杆菌,铜绿假单胞菌)和耐甲氧西林的21株临床分离的金黄色葡萄球菌。的抗真菌活性对四名酵母评价(念珠菌白色念珠菌,假丝酵母热带,念珠菌光滑念珠菌和副念珠菌(Candida parapsilsilosis)。获得的结果表明,亲脂性与被测化合物的抗生素活性之间具有很强的正相关性。对于具有更长烷基链(4c – g; 8–14个碳)的五种化合物,它们对革兰氏阳性菌(MIC = 2–16μgml -1)的活性最佳,它们对念珠菌(Candida)的活性最高( MIC = 2–64μgml -1)。化合物4e对临床分离的MRSA表现出最高水平的抑制活性(MIC = 2–16μgml
