In the present study, we examined the interaction of antimicrobial agents with four model lipid membranes that mimicked mammalian cell membranes and Gram-positive and -negative bacterial membranes and analyzed the binding kinetics using our surface plasmon resonance (SPR) technique. The selective and specific binding characteristics of antimicrobial agents(More)
We developed a surface plasmon resonance (SPR) assay to estimate the interactions of antimicrobial agents with the dipeptide terminal of lipid II (D-alanyl-D-alanine) and its analogous dipeptides (L-alanyl-L-alanine and D-alanyl-D-lactate) as ligands. The established SPR method showed the reproducible immobilization of ligands on sensor chip and analysis of(More)
Vancomycin-resistant Staphylococcus aureus (S. aureus) (VRSA) uses depsipeptide-containing modified cell-wall precursors for the biosynthesis of peptidoglycan. Transglycosylase is responsible for the polymerization of the peptidoglycan, and the penicillin-binding protein 2 (PBP2) plays a major role in the polymerization among several transglycosylases of(More)
Pseudomonas aeruginosa is one of the most common and clinically important pathogens because of its resistance to a wide variety of antibiotics. A number of treatments of P. aeruginosa have been developed, but there is still no definitive one. Antisense drugs have a great potential to treat multidrug-resistant P. aeruginosa because this technology, in(More)
