Flavonoids as Inhibitors of Bacterial Efflux Pumps [PDF]

open access: yesMolecules, 2021
Flavonoids are widely occurring secondary plant constituents, and are abundant in vegetable and fruit diets as well as herbal medicines. Therapeutic treatment options for bacterial infections are limited due to the spread of antimicrobial resistances.

Multidrug Efflux Pumps in Bacteria and Efflux Pump Inhibitors

open access: yesPostępy Mikrobiologii - Advancements of Microbiology, 2022
Abstract Antimicrobial resistance is becoming a paramount health concern nowadays. The increasing drug resistance in microbes is due to improper medications or over usage of drugs. Bacteria develop many mechanisms to extrude the antibiotics entering the cell. The most prominent are the efflux pumps (EPs).

Efflux Pump Inhibitors against Nontuberculous Mycobacteria [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
Over the last years, nontuberculous mycobacteria (NTM) have emerged as important human pathogens. Infections caused by NTM are often difficult to treat due to an intrinsic multidrug resistance for the presence of a lipid-rich outer membrane, thus encouraging an urgent need for the development of new drugs for the treatment of mycobacterial infections ...

Bacterial efflux pump inhibitors from natural sources [PDF]

open access: yesJournal of Antimicrobial Chemotherapy, 2006
The rapid spread of bacteria expressing multidrug resistance (MDR) has necessitated the discovery of new antibacterials and resistance-modifying agents. Since the initial discovery of bacterial efflux pumps in the 1980s, many have been characterized in community- and hospital-acquired Gram-positive and Gram-negative pathogens, such as Staphylococcus ...

Detection of tetracyclines and efflux pump inhibitors [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1993
Screening assays for the detection of tetracyclines and inhibitors of tetracycline efflux pumps are described. The tetracycline assay is based on the observation that the tetA(B) gene encoding the efflux pump of transposon Tn10 is induced by tetracycline.

Effect of efflux pump inhibition on Pseudomonas aeruginosa transcriptome and virulence [PDF]

open access: yes, 2017
Efflux pumps of the resistance-nodulation-cell-division (RND) family increase antibiotic resistance in many bacterial pathogens, representing candidate targets for the development of antibiotic adjuvants.

Repurposing bioactive aporphine alkaloids as efflux pump inhibitors [PDF]

open access: yesFitoterapia, 2019
Extrusion of drugs or drug-like compounds through bacterial efflux pumps is a serious health issue that leads to loss in drug efficacy. Combinatorial therapies of low-efficacy drugs with efflux pump inhibitors may help to restore the activities of such drugs.

Antisense PNA accumulates in Escherichia coli and mediates a long post-antibiotic effect [PDF]

open access: yes, 2007
Antisense agents that target growth-essential genes display surprisingly potent bactericidal properties. In particular, peptide nucleic acid (PNA) and phosphorodiamidate morpholino oligomers linked to cationic carrier peptides are effective in time kill ...

Enhanced efficacy of putative efflux pump inhibitor/antibiotic combination treatments versus MDR strains of Pseudomonas aeruginosa in a Galleria mellonella in vivo infection model [PDF]

open access: yes, 2015
This work was supported by the University of St Andrews.Objectives: The objectives of this study were to compare the antibiotic susceptibility of Pseudomonas aeruginosa strains with increased efflux pump expression in vitro and in vivo and to use these ...

Interplay between three RND efflux pumps in doxycycline-selected strains of Burkholderia thailandensis. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Efflux systems are involved in multidrug resistance in most Gram-negative non-fermentative bacteria. We have chosen Burkholderia thailandensis to dissect the development of multidrug resistance phenotypes under antibiotic pressure ...
