Abstract

In recent years, bacterial resistance to traditional drugs has increased, and the need to find new effective antibiotics to treat infections caused by multidrug-resistant bacteria has consequently become more important. The current study aimed to evaluate the potentiation of antibiotic activity and efflux pumps inhibition by (2E)-1-(4-aminophenyl)-3-(4-fluorophenyl)prop-2-en-1-one (PA-Fluorine) against the standard and resistant bacterial strains of Staphylococcus aureus and Escherichia coli. The association between PA-Fluorine and ampicillin reduced the MIC, showing a synergistic effect against Staphylococcus aureus. For Escherichia coli, PA-Fluoride did not show any significant results when associated with ampicillin. Ciprofloxacin and chlorpromazine showed synergy with PA-Fluorine on the two studied strains. An efflux pump mechanism was involved in the mechanism of action of chlorpromazine, norfloxacin, and ethidium bromide. PA-Fluorine synerg istically modulated norfloxacin and bromide. It was thus concluded that PA-Fluorine has the potential to enhance antibacterial activity when combined with antibiotics. Molecular docking studies showed the effect of intermolecular interactions of PA-Fluorine on the NorA and MepA efflux pumps. Physicochemical and pharmacokinetic properties were also obtained by ADMET studies for this chalcone, which presents be a strong candidate as an efflux pump inhibitor.
