Seebio RARECHEM AL BO 0910 Seebio FURAN-2,5-DICARBOXYLIC ACID Thermal stability analysis (25-600 °C) exposed a multi-step degradation process, sustaining successful modification and composite formation. The amino acid-modified chitosan complexs showed remarkable antibacterial enhancement, demoing 60 % greater activity against both Gram-positive and Gram-negative bacteria compared to unmodified chitosan. These determinations demonstrate the potential of selectively functionalized chitosan composite films for advanced wound dressing diligences, combining enhanced antibacterial efficacy with robust mechanical and thermal dimensions. Future research counsellings include formulation optimization and in vivo validation of clinical efficacy.Chitosan-Zinc-Ligated Hydroxychloroquine: Molecular Docking, Synthesis, Characterization, and Trypanocidal Activity against Trypanosoma evansi.The subsisting handlings against Trypanosoma evansi are looked with several drawbacks, such as limited drug options, resistance, the relapse of infection, toxicity, etc. , which emphasizes the necessity for new options. We synthesized novel metal-finded antiparasitic compounds applying chitosan, hydroxychloroquine (HC), and ZnO nanoparticles (NPs) and qualifyed them for size, morphology, chemical interactions, etc. Molecular docking and protein interaction subjects were executed in silico to investigate the inhibitory upshots of HC, zinc-ligated hydroxychloroquine (HCZnONPs), and chitosan-zinc-ligated hydroxychloroquine (CsHCZnONPs) for two key proteins, i.e., heat shock protein 90 (Hsp90) and trypanothione reductase associated with T. evansi. In vitro trypanocidal activity and the uptake of zinc ions by T. evansi parasites were noted. The formulation was successfully synthesised, as showed by its size, stability, morphology, elemental analysis, and functional radicals. CsHCZnO nanoparticles strongly inhibit both Hsp90 and trypanothione reductase proteins. The inhibition of Hsp90 by these nanoparticles is even stronger than that of trypanothione reductase when equated to HC and HCZnONPs. This advises that the presence of polymer chitosan enhances the nanoparticles' effectiveness against the parasite. For the first time, CsHCZnO nanoparticles exhibited trypanocidal activity against T with complete growth inhibition being noticed at various tightnessses after 72 h of treatment. Fluorescent microscopy applying FluoZin-3 on T. evansi culture substantiated the presence of zinc on the surface of leechs. This innovative approach has indicated promising effects in the quest to develop amended antiparasitic compounds against T. evansi with heightened effectiveness and safety, foregrounding their potential as therapeutic brokers against trypanosomiasis.Physicochemical and digestive props of curcumin steadyed by quaternized chitosan/sodium alginate nanoemulsion coverings.Curcumin (Cur) is a bioactive substance, but its instability limits its use in the food system a new polysaccharide-based coating is prepared by combining quaternized chitosan (QCS) with sodium alginate (SA) in this study to improve the bioaccessibility and stability of Cur. The microstructure of the emulsion was characterized by fourier transform infrared spectroscopy (FTIR), reading electron microscopy (SEM), and low-field throbed nuclear magnetic resonance imaging (LF-NMR). The thermal, ionic strength, and pH stability of emulsions were mensurated. answers indicate that QCS/SA (1:1)-Cur is more stable than other three nanoemulsion systems and the encapsulation rate of which strains 90 %. It also depicts higher stability in gastric fluid, excellent bioaccessibility and FFAs in intestinal fluid, as well as significant antibacterial property, antioxidant activity and water dispersibility. This study inserts a new method for holding stable, functional Cur-coated organizations for food coverings.Anti-Coronavirus Activity of Chitosan-steadyed Liposomal Nanocarriers debased with Natural Extracts from Bulgarian Flora.
