Biochemical Pharmacology, 2000 Active efflux from procaryotic as well as eucaryotic cells strongly modulates the activity of a large number of antibiotics. Effective antibiotic transport has now been observed for many classes of drug efflux pumps. Thus, within the group of primary active transporters, predominant in eucaryotes, six families belonging to the ATP-binding cassette ...

Leishmaniasis: efflux pumps and chemoresistance
International Journal of Antimicrobial Agents, 2003Resistance of parasitic protozoa such as Leishmania to therapeutic drugs continues to escalate in developing countries. Treatment programs for human leishmaniasis are still based on pentavalent antimonials but resistance to these compounds has been a persistent problem.

An Overview of Bacterial Efflux Pumps and Computational Approaches to Study Efflux Pump Inhibitors
Future Medicinal Chemistry, 2016 Micro-organisms express a wide range of transmembrane pumps known as multidrug efflux pumps that improve the micro-organism's ability to survive in severe environments and contribute to resistance against antibiotic and antimicrobial agents. There is significant interest in developing efflux inhibitors as an adjunct to treatment with current and next ...

Mycobacterial efflux pumps and chemotherapeutic implications
International Journal of Antimicrobial Agents, 2003The demonstration of the existence of active efflux pumps in mycobacteria raises the question of whether or not these can increase in number and activity rendering wild-type mycobacteria increasingly resistant to a given antibiotic. This could be a mechanism by which mutated resistant strains become better fit to the selective environment ...

Bacterial Efflux Pump Inhibitors
2008Infections caused by multidrug-resistant Gram-negative pathogens play a major role in the morbidity and mortality of hospitalized patients. The rise of resistance to current antibiotic therapies has made the discovery of new agents urgent. One of the major antibiotic resistance mechanisms utilized by more than 15 species of Gram-negative bacterial ...

Efflux pump inhibitors: new updates
Pharmacological Reports, 2020The discovery of antibiotics ought to have ended the issue of bacterial infections, but this was not the case as it has led to the evolution of various mechanisms of bacterial resistance against various antibiotics. The efflux pump remains one of the mechanisms through which organisms develop resistance against antibiotics; this is because organisms ...

Bacterial efflux systems and efflux pumps inhibitors
Biochimie, 2005It is now well established that bacterial resistance to antibiotics has become a serious problem of public health that concerns almost all antibacterial agents and that manifests in all fields of their application. Among the three main mechanisms involved in bacterial resistance (target modification, antibiotic inactivation or default of its ...

Efflux Pumps in Drug Resistance of Candida
Infectious Disorders - Drug Targets, 2006The incidences of human pathogenic yeast Candida albicans and its related species acquiring resistance to antifungals have increased considerably, which poses serious problems towards its successful chemotherapy. The resistance of these pathogenic fungi is not restricted to the commonly used triazole compounds but is even encountered, though not often,

Computational modelling of efflux pumps and their inhibitors [PDF]
Essays in Biochemistry, 2017 Antimicrobial resistance is based on the multifarious strategies that bacteria adopt to face antibiotic therapies, making it a key public health concern of our era. Among these strategies, efflux pumps (EPs) contribute significantly to increase the levels and profiles of resistance by expelling a broad range of unrelated compounds – buying time for the

Antibiotic Resistance Antibiotic resistance is an alarming and growing challenge. Bacteria show great heterogeneity in growth and mutation rates. Such variability allows some cells to persist during transient antibiotic exposure. During this persistent phase, mutations accumulate, which can result in selection for full-blown antibiotic resistance.
