This paper presents the synthesis and characterization of new thiosemicarbazone derivatives with potential applications as antibacterial, antioxidant and anticancer agents. Six thiosemicarbazone derivatives (L-L5) were synthesized by reacting an appropriate thiosemicarbazide derivative with 2-pyridinecarboxaldehyde. The structures of the obtained compounds were confirmed using mass spectrometry, infrared spectroscopy, and NMR spectroscopy.

- The research focuses on using natural preservatives from berry juices to keep minimally processed foods safe and stable.
- The study tested juices from four berry species against the food pathogen Bacillus cereus, finding that chokeberry had the strongest antibacterial effect, while elderberry showed no inhibition.
- It suggests that the juice's effectiveness is linked to its antioxidant properties rather than just acidity or anthocyanin levels, enhancing our understanding of using berry extracts as biopreservatives.
Immunoreactive gluten peptides that are not digested by peptidases produced by humans can trigger celiac disease, allergy and non-celiac gluten hypersensitivity. The aim of this study was to evaluate the ability of selected probiotic strains to hydrolyze immunoreactive gliadin peptides and to identify peptidase-encoding genes in the genomes of the most efficient strains. Residual gliadin immunoreactivity was measured after one- or two-step hydrolysis using commercial enzymes and bacterial peptidase preparations by G12 and R5 immunoenzymatic assays.

The effects of cyclodextrin encapsulation on hesperetin's derivatives (HHSB, HIN, and HTSC) and the physicochemical properties of the formed complexes were determined using various analytical techniques. The antioxidant (DPPH, ABTS scavenging, and Fe-chelating ability), cytotoxic, and antibacterial activities were also investigated.
