All the compounds were fully characterized using H-1 and C-13 nuclear magnetic resonance, liquid chromatography-mass spectrometry, infrared spectroscopic methods, and elemental analyses. Antimicrobial activities of the compounds were tested against the bacteria Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Enterococcus faecalis, and the fungal strains Candida albicans and Candida glabrata, and promising results were achieved. The two most important benzyl-substituted benzimidazolium chlorides, 3l and 3k, showed comparable activity to vancomycin against MRSA.eninfo:eu-repo/semantics/closedAccessantibacterialantifungalbenzimidazoliumcatecholimidazoliumArticle35363230116910.1002/ardp.2020000132-s2.0-85083511029Q2WOS:000526691400001Q2
