Hydrogels for biomedical applications.

Differently substituted flavanones were isolated from Leguminosae and their antibacterial activity was comparatively studied against methicillin-resistant Staphylococcus aureus (MRSA). The minimum inhibitory concentrations (MICs) of phytochemical flavanones to clinical isolates of MRSA were determined by a serial agar dilution method. The structure-activity relationship has indicated that 2',4'- or 2',6'-dihydroxylation of the B ring and 5,7-dihydroxylation of the A ring in the flavanone structure are important for significant anti-MRSA activity and that substitution with a certain aliphatic group at the 6- or 8-position also enhances the activity. Among the thirteen flavanones tested, tetrahydroxyflavanones with these structural characteristics isolated from Sophora exigua and Echinosophora koreensis showed intensive activity to inhibit the growth of all MRSA strains at 3.13-6.25 micrograms/ml. The present hydroxyflavanones would be useful in the phytotherapeutic strategy against MRSA infections.

Listeria monocytogenes (L. monocytogenes) contamination in cheese production has received increasing attention. In order to inhibit the multiplication of the bacteria, the polyethylene oxide nanofibers containing nisin-loaded poly-γ-glutamic acid/chitosan (NGC) nanoparticles were engineered in this study. The physicochemical properties of NGC nanoparticles and anti-listeria activities of NGC nanoparticles-embedded polyethylene oxide nanofibers on cheese were investigated. The results indicated that NGC nanoparticles at 5 mg/mL of nisin had desirable polydispersity, zeta potential, encapsulation efficiency and load capacity. NGC nanoparticles-embedded polyethylene oxide nanofibers displayed satisfactory antibacterial activity against L. monocytogenes on cheese, without impact on the sensory quality. Therefore, the polyethylene oxide nanofibers containing NGC nanoparticles could be a promising active packaging for food preservation.
