    Antimicrobial Activity of a Series 1-Alkyl-2-(4-Pyridyl)Pyridinium Bromides against Gram-Positive and Gram-Negative Bacteria

  • Original language description

    A series of 1-alkyl-2-(4-pyridyl)pyridinium bromides with alkyl chains containing between 9 and 16 carbons were tested against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli, Stenotrophomonas maltophilia, Acinetobacter baumannii and Pseudomonas aeruginosa) bacteria.The compounds were most active against S.aureus. The most active compounds had alkyl chain lengths of between 11 and 16 carbons. The activity of the compounds against Gram-negative organisms was increased when the membrane-permeabilizing agent sodium citrate was introduced. Critical micelle concentrations of the compounds were much higher than minimum inhibitory concentrations of the inhibitors.

    Antimikrobiální aktivita serie 1-alkyl-2-(4-pyridyl)pyridinium-bromidů vůči gram-pozitivním a gram-negativním bakteriím

  • Czech description

    Serie 1-alkyl-2-(4-pyridyl)pyridinium-bromidů s alkyl-substitucí, obsahující 9 až 16 C byla testována proti gram-pozitivním (Staphylococcus aureus) a gram-negativním (Escherichia coli, Stenotrophomonas maltophilia, Acinetobacter baumannii a Pseudomonas aeruginosa) bakteriím. Sloučeniny vykazovaly nejvyšší aktivitu vůči S.aureus. Nejaktivnější sloučeniny byly s alkylovým řetězcem 11 až 16 C. Aktivita sloučenin proti gram-negativním mikroorganizmům se zvýšila přídavkem citronanu sodného, zvyšujícího permeabilitu membrán. Kritická micelární koncentrace sloučenin byla mnohem vyšší než koncentrace inhibiční.
