Homology modeling, molecular dynamics, and virtual screening of NorA efflux pump inhibitors of Staphylococcus aureus
Emerging drug resistance in clinical isolates of Staphylococcus aureus might be implicated to the overexpression of NorA efflux pump which is capable of extruding numerous structurally diverse compounds. However, NorA efflux pump is considered as a potential drug target for the development of efflux pump inhibitors. In the present study, NorA model was constructed based on the crystal structure...
متن کاملThe Effect of Thyme (Thymus vulgaris) Extract on the Expression of norA Efflux Pump Gene in Clinical Strains of Staphylococcus aureus
The NorA efflux pump considered as one of the contributors to antibiotic resistance in Staphylococcus aureus strains. One of the challenges of the researchers is finding natural plant compounds with the ability to inhibit the pumps. The aim of this study was to investigate the inhibitory effect of thyme (Thymus vulgaris) extract on NorA efflux pump in ciprofloxacin-resistant strains of S. aureu...
متن کاملSynthesis of omeprazole analogues and evaluation of these as potential inhibitors of the multidrug efflux pump NorA of Staphylococcus aureus.
A series of 11 pyrrolo[1,2-a]quinoxaline derivatives, 1a to 1k, sharing structural analogies with omeprazole, a eukaryotic efflux pump inhibitor (EPI) used as an antiulcer agent, was synthesized. Their inhibitory effect was evaluated using Staphylococcus aureus strain SA-1199B overexpressing NorA. By determinations of the MIC of norfloxacin in the presence of these EPIs devoid of intrinsic anti...
متن کاملCapsaicin, a novel inhibitor of the NorA efflux pump, reduces the intracellular invasion of Staphylococcus aureus.
OBJECTIVES To delineate the role of capsaicin (8-methyl-N-vanillyl-6-nonenamide) as an inhibitor of the NorA efflux pump and its impact on invasion of macrophages by Staphylococcus aureus. METHODS Capsaicin in combination with ciprofloxacin was tested for activity against S. aureus SA-1199B (NorA overproducing), SA-1199 (wild-type) and SA-K1758 (norA knockout). The role of NorA in the intrace...
متن کاملEffects of synthesized iron oxide nanoparticles from Ziziphora clinopodioides on expression of the efflux pump genes of Staphylococcus aureus
Introduction: One of the important factors causing nosocomial infections is drug-resistant Staphylococcus aureus strain, so correspondingly, having norA efflux pump is one of the bacterial's ability to generate drug resistance. Iron has been used as a nanoparticle with antimicrobial activity against bacteria. The aim of this study was to investigate the effect of iron oxide nanoparticles synthe...
