An important aspect of food technology is that vitamin compounds can be used for a variety of purposes, such as developing methods to enhance the nutritional value of foods. This paper discusses the synthesis and properties of β-cyclodextrin (β-CD)-functionalized silver nanoparticles, and the use of the resulting β-CD-AgNP inclusion complex when loading vitamin D3 (cholecalciferol, VD3) molecules. β-Cyclodextrin was used as a reducing agent and a stabilizer in the production of silver nanoparticles. The preparation of VD3-β-CD-AgNP nanocompositions was confirmed by UV spectroscopy, transmission electron microscopy, and X-ray diffraction spectroscopy. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that the resulting β-CD-VD3-AgNP nanocomposite was well dispersed with particle sizes ranging from 6 to 15 nm. 1H-, 13C-NMR and FTIR spectroscopy showed the reduction of silver ions and the formation of β-CD-encapsulated AgNPs. The kinetic parameters of the thermal decomposition reaction of the VD3-β-CD-AgNP nanocomposition have been determined under nonisothermal conditions that ensure the preservation of the kinetic triplet and a more accurate description of the process. The nanocomposition of VD3 with silver nanoparticles demonstrated antibacterial activity against the used bacteria.
The paper presents the synthesis of new naphthyl-containing derivatives of thiosemicarbazide and thiourea, their water-soluble inclusion complexes with β-cyclodextrin, as well as an assessment of their potential antiviral and hemorheological activity. As a criterion for the specific antiviral effect of new compounds, their chemotherapeutic indices were calculated using predictive analytics tools driven by artificial intelligence and molecular docking methods. Molecular docking studies with three protein targets PknB (2FUM), DprE1 (6HEZ), and InhA (1ENY) confirmed strong and specific ligand–protein interactions. The effects of structural features of new compounds on the rheological characteristics of blood were considered, and the most promising samples were identified for further in-depth in vitro study of their specific biological activity. The performed thermoanalytical study showed that the structure of the included ligand, as well as the shape of the receptor, significantly affect the thermal stability and kinetic parameters of the decomposition of the inclusion complex. In silico evaluation of the newly synthesized compounds revealed promising biological activity profiles, with all compounds demonstrating predicted antimycobacterial and antituberculosis potential. In silico analysis of the newly synthesized compounds revealed favorable biological activity profiles, with all candidates demonstrating predicted antimycobacterial and antituberculosis potential.
