respectively. The compound 4-((dimethylamino)methyl)-2-isopropyl-5-methylphenol, 4 g had a good inhibition against E. coli and S. aureus at MIC 6.25 μg/ml; and for T. rubrum at 3.12 μg/ml. The synthesized compounds 4 g and 4 h had the highest inhibition against the fungus, T. rubrum at inhibition with 27 and 28 mm, respectively. Thus, the synthesized compounds with methylated dimethylamino in thymol could be the
抗菌抗药性已经酝酿了几十年,现在已经成为潜在的公共卫生紧急事件,无处不在。因此,迫切需要更新的有效候选药物,以帮助克服细菌和真菌中的抗生素耐药性。通过相应的环胺3a- 3g和N-杂芳基-4-氨基苯磺酰胺3h-3l与百里酚和甲醛的曼尼希缩合反应,设计并合成了一系列含有百里酚的氨基甲基化磺酰胺同系物4a-4l在酸性介质中。合成的化合物通过光谱研究在结构上得到证实;1小时/ 13 C NMR、FTIR、ESI-HRMS和元素分析。通过XRD分析进行合成化合物的粉末表征。所得产品经筛选对尿路致病菌、金黄色葡萄球菌、化脓性链球菌和大肠杆菌进行抑菌试验;并用于热带念珠菌和红色毛癣菌的抗真菌试验。所有化合物的抗菌活性结果均表现出中等至极好的细菌抑制作用;而化合物2-异丙基-5-甲基-4-(吡咯烷-1-基甲基)苯酚,4F已经表现出抑制显著大肠杆菌和金黄色葡萄球菌MIC 分别为 3.12 μg/ml、12.5
