Abstract
The second part of this review is concerned with analysis of the possible effect of flavonoids on the SARS-CoV-2 enzymes directly involved in the infectious cycle of the virus, taking into account the peculiarities of host cell functioning. The results of virtual screening of flavonoids in conditions of molecular docking and molecular modeling are considered in this review. In the experiments in silico, binding of flavonoids to three SARS-CoV-2 enzymes was analyzed: 3-chymotrypsin-like protease (3CLpro), papain-like protease (PLpro), and RNA-dependent RNA polymerase (RdRp). A high affinity of binding of flavonoids to these viral proteins (most pronounced for flavonols, flavones, and flavan-3-ols and often superior to the control antiviral drugs) was demonstrated. The process of penetration of SARS-CoV-2 into the cell and host cell components involved in the infectious cycle of the virus, as well as the possible effect of flavonoids on them, are considered separately.
期刊介绍：
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
