ABSTRACT

Biomaterial research has improved the delivery and efficacy of drugs over a wide range of pharmaceutical applications. The objective of this study was to synthesize benzodioxane coupled piperazine decorated chitosan silver nanoparticle (Bcp*C@AgNPs) against methicillin-resistant Staphylococcus aureus (MRSA) and to assess the nanoparticle as an effective candidate for antibacterial and anti-biofilm care. Antibacterial activity of the compound was examined and minimum inhibitory concentration (MIC) was observed at (10.21 ± 0.03 ZOI) a concentration of 200 μg/mL. The Bcp*C@AgNPs interferes with surface adherence of MRSA, suggesting an anti-biofilm distinctive property that is verified for the first time by confocal laser microscopic studies. By ADMET studies the absorption, distribution, metabolism, excretion and toxicity of the compound was examined. The interaction solidity and the stability of the compound when surrounded by water molecules were analyzed by docking and dynamic simulation analysis. The myoblast cell line (L6) was considered for toxicity study and was observed that the compound exhibited less toxic effect. This current research highlights the biocidal efficiency of Bcp*C@AgNPs with their bactericidal and anti-biofilm properties over potential interesting clinical trial targets in future.
