Synthesis and Properties of Cleavable Quaternary Ammonium Compounds

open access: yesJournal of Oleo Science, 2021
Quaternary ammonium compounds are widely used as antiseptic and disinfectant. It is been a concern that their widespread use will lead to an increase of environmental problems, therefore the development of biodegradable surfactants is necessary. The present research is aimed at the design of novel amphiphilic molecules with similar properties to those ...

Exposure of ciprofloxacin-resistant Escherichia coli broiler isolates to subinhibitory concentrations of a quaternary ammonium compound does not increase antibiotic resistance gene transfer [PDF]

open access: yes, 2019
Resistance to antibiotics threatens to become a worldwide health problem. An important attributing phenomenon in this context is that pathogens can acquire antibiotic resistance genes through conjugative transfer of plasmids.

Coresistance to quaternary ammonium compounds in extended-spectrum beta-lactamase-producing Escherichia coli [PDF]

open access: yesInternational Journal of One Health, 2020
Background and Aim: Extended-spectrum β-lactamases (ESBL) in Escherichia coli constitutes one of the major threats to modern medicine, and the increasing pollution with quaternary ammonium compounds (QACs) has been suspected to contribute to the spread ...

Limited association between disinfectant use and either antibiotic or disinfectant susceptibility of Escherichia coli in both poultry and pig husbandry [PDF]

open access: yes, 2019
Background Farm disinfectants are widely used in primary production, but questions have been raised if their use can select for antimicrobial resistance.

Quaternary Ammonium Leucine-Based Surfactants: The Effect of a Benzyl Group on Physicochemical Properties and Antimicrobial Activity

open access: yesPharmaceutics, 2019
Quaternary ammonium amphiphiles are a class of compounds with a wide range of commercial and industrial uses. In the pharmaceutical field, the most common quaternary ammonium surfactant is benzalkonium chloride (BAC), which is employed as a preservative ...

Strategies for studying permeation at voltage-gated ion channels [PDF]

open access: yes, 1991
Voltage-dependent ion channels are presently thought to consist of several distinct functional regions: (a) activation gates, (b) inactivation gates, and permeation pathways.

Synthesis, characterization, and bioactivity of rosin quaternary ammonium salt derivatives [PDF]

open access: yesBioResources, 2013
Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1HNMR, and the bioactivity was determined by filter paper method using Trametes ...
