Synthesis and Properties of Cleavable Quaternary Ammonium Compounds
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]
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]
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]
Background Farm disinfectants are widely used in primary production, but questions have been raised if their use can select for antimicrobial resistance.

Strategies for studying permeation at voltage-gated ion channels [PDF]
Voltage-dependent ion channels are presently thought to consist of several distinct functional regions: (a) activation gates, (b) inactivation gates, and permeation pathways.

Non-leaching antimicrobial surfaces through polydopamine bio-inspired coating of quaternary ammonium salts or an ultrashort antimicrobial lipopeptide. [PDF]
Bacterial fouling on surfaces significantly increases the resistance of bacteria toward antibiotics, which leads to medical complications and a corresponding financial burden.

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