Cinacalcet exhibits rapid bactericidal and efficient anti-biofilm activities against multidrug-resistant Gram-positive pathogens.

ABSTRACT: Infections caused by Gram-positive bacteria pose a serious threat to global public health. Drug resistance, dormant persister cells, and biofilm formation are the key challenges affecting the efficacy of antibiotics against Gram-positive bacterial infections. In this study, cinacalcet exhibited good inhibitory activity against multidrug-resistant Gram-positive bacteria, with minimum inhibitory concentrations (MICs) ranging from 3.13 μg/mL to 25 μg/mL. Cinacalcet displayed more rapid and stronger bactericidal activity against planktonic and persister cells of Staphylococcus aureus and Enterococcus faecalis compared with the antibiotics vancomycin or ampicillin, as well as potent inhibition and eradication of mature biofilms of methicillin-resistant S. aureus (MRSA) and
