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

Carbonic anhydrase inhibition and cytotoxicity studies of Mannich base derivatives of thymol
Mannich bases of thymol were synthesized. The aminomethylation reaction was realised in the ortho position of the phenol for compounds 2 (dipropylamine), 3 (benzylamine), and 4 (dibenzylamine) while it was from para position for 1 (dimethylamine), 5 (piperidine), 6 (morpholine) and 7 (N-methylpiperazine). The carbonic anhydrase (CA, EC 4.2.1.1) inhibitory effects of the compounds were asssessed against
