Abstract:
Novel para-substituted bis-pyridinium compounds containing 2,7-dioxynaphthalene spacer were synthesized in two simple steps from the corresponding dihydroxy-naphthalene. The microbiological study on five reference (E. coli ATCC 25922, K. pneumoniae ATCC 70060, S. aureus ATCC 43300, P. aeruginosa ATCC27853, and A. baumannii ATCC 15308) and five clinical (E. coli B-3421/19,K. pneumoniae B-2523/18, S. aureus B-8648, P. aeruginosa B-2099/18 and A. baumannii B-2926/18) bacterial strains showed promising range of antibacterial properties for these biocides, compared to modern sanitizers.
