Abstract
It has been shown that the development of coronavirus infection (COVID-19), especially in severe cases, is accompanied by hypoxia as a result of several pathological processes: alveolar blood supply disorders, hemolysis, COVID-associated coagulopathy. Under these conditions, the level of reactive oxygen species is increased and it is more likely that free-radical damage to biomolecules is caused by the process of free-radical fragmentation than oxidation. In contrast to the oxidation process, free-radical fragmentation reactions are more effectively inhibited by oxidizing agents than reducing agents. Therefore, the use of substances possessing both reducing and oxidizing properties, such as natural and synthetic quinones, bioflavonoids, curcuminoids, should reduce the probability of biomolecule destruction by oxidation as well as free-radical fragmentation processes.HighlightsCOVID-19 is accompanied by the iron release from the heme and «silent» hypoxiaROS initiate fragmentation reactions of biomolecules under conditions of hypoxiaBlocking of fragmentation process by oxidizers may lead to mitigation of COVID-19.

Abstract
The monosaccharides, glucose, fructose and galactose, are the most common and simplest forms of carbohydrates. The aim of this study was to determine the uptake of glucose as a potential therapeutic target agent for cancer treatment. The stability and transportation calculations of the monosaccharides were carried out in the blood phase by using the density functional theory and docking. The reactivity of monosaccharides, disaccharides and their transportation with GLUT1 and GLUT3 as prognostic indicators for cancer were investigated. The theoretical results of this study were supported by those reported in the literature and used in the prediction of the mechanisms of monosaccharides and the interpretation of their reactivities.
