A series of novel 2-arylimino-3-aryl-thiazolidine-4-ones was designed, synthesized and tested for in vitro antibiofilm activity against Staphylococcus epidermidis. Among them tested, some compounds with carboxylic acid groups showed good antibiofilm activity. The antibiofilm concentration of 1x was 6.25 microM. The structure-activity relationships revealed that incorporation of 2-phenylfuran moiety could greatly enhance antibiofilm activity of thiazolidine-4-one.

The current study was designed to evaluate the antibacterial, antibiofilm, and biofilm inhibitory potential of six medicinal plants, including Trachyspermum ammi, Trigonella foenum-graecum, Nigella sativa, Thymus vulgaris, Terminalia arjuna, and Ipomoea carneaid against catheter-associated bacteria (CAB). Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.

Anti-infective agents are a class of drugs used to prevent, treat, or control infections caused by microorganisms such as bacteria, viruses, fungi, and parasites. They play a crucial role in modern medicine, helping to reduce the severity of infections and, in many cases, save lives. This study aims at the design and synthesis of hybrid compounds containing quinoxaline, pyrrolidine, and an azo bridge to combat antimicrobial resistance, and evaluating their antimicrobial, antifungal, and antiviral activities against various pathogenic strains.

The main objective of this study is to prepare sodium alginate (SA)-based biofilms incorporated with watercress oil (WCO) as an antimicrobial material for sustainable food packaging. The physicochemical, antioxidant, and antibacterial properties of the prepared bio-based films were investigated. The antioxidant activity showed a remarkable increase, with DPPH inhibition increasing from 13.

This study introduces a novel approach to enhance the antibacterial properties of UIO-66 by incorporating both Thymol and ZnO nanoparticles within its framework which represents a significant advancement like exhibiting a synergistic antibacterial effect, providing a prolonged and controlled release, and mitigating cytotoxicity associated with the release of free ZnO nanoparticles by combining these two antimicrobial agents within a single, well-defined metal-organic framework. UIO-66 frameworks are investigated as carriers for the natural antimicrobial agent, Thymol, and ZnONPs offering a novel drug delivery system for antibacterial applications. Results demonstrated 132, 90, 184, and 223 nm sizes for UIO-66, ZnONPs, UIO-66 encapsulated Thymol, and UIO-66 encapsulated both Thymol and ZnONPs, respectively.

Aim: To evaluate in vitro the antibacterial efficacy and cytocompatibility of different implant-decontamination methods, using both 2D and 3D peri-implant mucosa models.
Methods: Four decontamination methods [chlorhexidine (CHX), electrolytic treatment (GS), curcumin (CUR), xanthohumol (XN)] were compared in four independent experiments, three with a 2D peri-implant mucosa model on titanium surfaces and another on a 3D peri-implant mucosa model. These decontamination procedures were tested for their antibacterial effect using a multispecies biofilm model with Streptococcus oralis, Actinomyces naeslundii, Veillonella dispar, and Porphyromonas gingivalis for 24 h.
