Benzimidazole derivatives are known to represent a class of medicinally important compounds which are extensively used in drug design and catalysis. A series of 2-substituted benzimidazole derivatives 10a-i was herein synthesized from the reaction of o-phenylenediamine with some amino acids using ameliorable pathway. The chemical structures of the synthesized compounds were confirmed by IR, UV, 1H-NMR, 13C-NMR, Mass spectral and analytical data. The compounds were investigated for their antimicrobial activity alongside gentamicin clinical standard. The results showed that this skeletal framework exhibited marked potency as antimicrobial agents. The most active compound was 1H-benzo[d]imidazol-2-yl)methanamine, 10a.
苯并咪唑衍生物是一类在药物设计和催化中被广泛应用的重要药物化合物。本文通过改进的路径,从邻苯二胺与某些氨基酸的反应中合成了系列2-取代苯并咪唑衍生物10a-i。通过IR、UV、1H-NMR、13C-NMR、质谱和分析数据确认了所合成化合物的化学结构。这些化合物与庆大霉素临床标准一起进行了抗菌活性研究。结果表明,这种骨架结构表现出显著的抗菌效力。活性最高的化合物是1H-苯并[d]咪唑-2-基)甲胺,10a。
