Physical and chemical characteristics, antioxidant properties and the effect of the newly synthesized peptide on lipid deposition in cells
A novel peptide, CG-16, with the sequence CHAECGAACKEFCLEG, was designed and synthesized. Studies were conducted to assess its physicochemical properties, antioxidant activity, and effects on lipid deposition in cells in an in vitro experiment. It was established that the CG-16 peptide does not contain antigenic determinants. A search across the PeptideAtlas, UniProt, and the National Center for Biotechnology ...
Callus cultures of Spergularia marina (L.) Griseb.: obtaining and phytochemical analysis
In recent decades, interest in halophyte plants has increased due to their high content of biologically active substances with powerful antioxidant, antimicrobial, anti-inflammatory and antitumor properties and promising for the prevention of various diseases. Several species of halophytes grow on the territory of the Kaliningrad region, among which the rare species Spergularia marina ...
The use of a gas discharge visualization technique at estimation the antioxidant status of plants in the conditions of cadmium toxic effect
This article presents an evaluation of the antioxidant status of plants with the use of the GDV-method under the toxic effect of cadmium. A high concentration of Сd in the soil is proven to stimulate the accumulation of anthocyans, carotenoids, and acorbic acid and to contribute to a reduction ...
A study into the antyoxidantive activity of amaranth in the conditions of a black-soil region
... high content of antioxidantive substances in Amaranthus and identified the dependence of the extract antioxidantive activity on the method and period of sample collection, as well as the method of extraction and storage period. The highest content of antioxidants was registered in water extracts in September. The most effective method of sample collection is obtaining extracts from dry leaves of Amaranthus and storing water solution for further use for not more than 5 months. The best period for plant ...
Comparison of the methods of total antioxidant activity analysis
Five varieties of apples from the Baltic region were studied by means of two different analytical methods. The results of experiment demonstrate that the values of total antioxidant activity obtained through spectrophotometric and amperometric methods are comparable. The authors determined the relation between the total content of ascorbic acid and phenolic compounds in apples, pulp, and juice of the variety.

Increased biosynthesis of secondary metabolites in callus cultures of Hyssopus officinalis L.
... conditions that enhance the biosynthesis of these compounds in callus cultures is highly relevant. This article examines the influence of various concentrations of phenylalanine and tyrosine (1—500 µM) on the content of phenolic compounds and the antioxidant activity of three callus cultures of Hyssopus officinalis L. It was found that the addition of phenylalanine at a concentration of 10 µM and tyrosine at a concentration of 100 µM to the nutrient media leads to an increase in the content ...
Comparative evaluation of the biological effect of native and synthesized peptides
... do not differ from natural ones in terms of physical and chemical characteristics. Both synthesized and natural peptides are non-toxic. The anti-diabetic effect of natural and synthesized peptide mpT2 on animals with induced type 2 diabetes and the antioxidant activity of synthesized and natural peptide T1.1 have been demonstrated.

. Increased synthesis of secondary metabolites in the culture of bearded roots of Hyssopus officinalis L
... the nutrient medium at a concentration of 1 μM, the maximum increase in biomass was observed. The content of biologically active substances in the bearded roots of H. officinalis, such as phenolic compounds, flavonoids, hydroxycinnamic acids and the antioxidant activity of extracts, were higher when tyrosine was introduced into the nutrient medium compared with phenylalanine supplements.
