Synthesis and microbiological properties of novel bis-quaternary ammonium compounds based on 4,4′-oxydiphenol spacer

, 2019
Novel gemini (tail–head–spacer–head–tail) bis-quaternary ammonium compounds with a 4,4′-oxydiphenol spacer between two pyridinium heads were synthesized and compared with commonly used antiseptics such as benzalkonium chloride and chlorhexidine gluconate.

Fluorescence method for determining the mechanism and speed of action of surface-active drugs on yeast cells

BioTechniques, 2011
New antifungal agents are needed to treat life-threatening fungal infections, particularly with the development of resistance. Surface-active antifungals have the advantages of minimizing host toxicity and the emergence of drug resistance.

mfsQ encoding an MFS efflux pump mediates adaptive protection of Stenotrophomonas maltophilia against benzalkonium chloride

, 2020
The persistence of Stenotrophomonas maltophilia, especially in hospital environments where disinfectants are used intensively, is one of the important factors that allow this opportunistic pathogen to establish nosocomial infections. In the present study,
