Evaluation of Delafloxacin against a Burkholderia pseudomallei Efflux Mutant Panel
Microbiology Spectrum, 2022 In vitro activities of delafloxacin and ciprofloxacin were evaluated against Burkholderia pseudomallei mutants expressing or lacking defined resistance-nodulation-cell division (RND) efflux pumps using CLSI methodology at pHs of 5.8 and 7.2. Delafloxacin

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

Bacterial Multidrug Efflux Pumps: Much More Than Antibiotic Resistance Determinants
Microorganisms, 2016 Bacterial multidrug efflux pumps are antibiotic resistance determinants present in all microorganisms. With few exceptions, they are chromosomally encoded and present a conserved organization both at the genetic and at the protein levels.

Molecular mechanism of MBX2319 inhibition of Escherichia coli AcrB multidrug efflux pump and comparison with other inhibitors [PDF]
, 2014 Efflux pumps of the resistance nodulation division (RND) superfamily, such as AcrB, make a major contribution to multidrug resistance in Gram-negative bacteria. The development of inhibitors of the RND pumps would improve the efficacy of current and next-

Versatility of Stenotrophomonas maltophilia: Ecological roles of RND efflux pumps
Heliyon, 2023 S. maltophilia is a widely distributed bacterium found in natural, anthropized and clinical environments. The genome of this opportunistic pathogen of environmental origin includes a large number of genes encoding RND efflux pumps independently of the ...

Genome-Wide Transposon Screen of a Pseudomonas syringae mexB Mutant Reveals the Substrates of Efflux Transporters. [PDF]
, 2019 Bacteria express numerous efflux transporters that confer resistance to diverse toxicants present in their environment. Due to a high level of functional redundancy of these transporters, it is difficult to identify those that are of most importance in ...

Efflux Pump Inhibitors against Nontuberculous Mycobacteria [PDF]
International 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 ...

Introduction: Transporters, Porins, and Efflux Pumps [PDF]
Chemical Reviews, 2021 All living cells are surrounded by lipidic membranes that separate metabolic and macromolecular biosynthetic processes from external environments. Biological membranes vary dramatically in their composition and structures and are optimized by mega-annum of evolution to effectively carry out diverse biological functions including energy production ...
