2-arylbenzimidazole derivatives followed by N-alkylation by conventional heating or microwave irradiation for diversification. Potent antibacterial compounds against MSSA and MRSA were discovered such as benzimidazole compounds 3k (2-(4-nitrophenyl), N-benzyl), 3l (2-(4-chlorophenyl), N-(4-chlorobenzyl)), 4c (2-(4-chlorophenyl), 6-methyl, N-benzyl), 4g (2-(4-nitrophenyl), 6-methyl, N-benzyl), and 4j (2-(4-nitrophenyl)
含有苯并咪唑部分的化合物在发现新的生物活性物质方面占据着优越的化学空间。继续我们最近的工作,使用有效的合成方案(即焦亚硫酸钠催化芳香醛与邻苯二胺缩合形成 2-芳基苯并咪唑衍生物,然后形成N- ),设计并合成了 69 种苯并咪唑衍生物,收率高达 46-99%。通过常规加热或微波辐射进行烷基化以实现多样化。发现了针对 MSSA 和 MRSA 的有效抗菌化合物,例如苯并咪唑化合物3k (2-(4-硝基苯基), N-苄基), 3l (2-(4-氯苯基), N- (4-氯苄基)), 4c (2 -(4-氯苯基),6-甲基, N-苄基), 4g (2-(4-硝基苯基),6-甲基, N-苄基),和4j (2-(4-硝基苯基),6-甲基, N- (4-氯苄基)),MIC 为 4–16 μg mL -1 。此外,化合物4c对大肠杆菌和粪链球菌表现出良好的抗菌活性(MIC = 16 μg mL -1 )。此外,化合物3k
