Action of Betulinic Acid in the Inhibition of Efflux Pump NorA in Staphylococcus aureus Strains: In Vitro and In Silico Approaches

Chemistry &Biodiversity, EarlyView.
ABSTRACT Antibiotic resistance poses a serious challenge to public health, particularly in the case of Staphylococcus aureus, a Gram‐positive bacterium that employs multiple resistance mechanisms, including efflux pumps such as NorA, which extrude antimicrobial compounds from the cell and reduce antibiotic efficacy. Therefore, the search for substances
