Integrated experimental and computational analysis reveals amoxicillin binding dynamics to PBP1a in Staphylococcus aureus.

ABSTRACT: Methicillin-resistant Staphylococcus aureus (MRSA) represents a significant global health challenge due to acquired resistance mechanisms, primarily involving penicillin-binding protein 2a (PBP2a), necessitating novel therapeutic strategies. This study explores the potential of amoxicillin-conjugated magnetic nanoparticles (Amox-MNPs) as a means to overcome resistance by targeting the alternative essential protein, PBP1a. Fe₃O₄@SiO₂ core-shell MNPs were synthesized via controlled co-precipitation followed by a silica coating using the Stöber method, and subsequently conjugated with amoxicillin. Physicochemical characterization confirmed nanoparticle formation and successful conjugation. In vitro antibacterial assays against S. aureus ATCC 43,300 (MRSA) revealed that Amox-MNPs exhibited a m
