PLANT SUBSTANCES AS POTENTIAL SOURCE OF ORIGINAL ANTI-VIRUS AGENTS

This article summarizes the literature data and the results of our own studies on the search for antiviral compounds based on terpenoids, flavonoids, alkaloids. New bimolecular and ketoamide derivatives based on sesquiterpene γ-lactones arglabin, grossheimin and α-santonin were synthesized in quantitative yields up to 80%. The molecular docking method was used to study the “structure-activity” relationship of natural compounds and their derivatives in relation to SARS-Cov-2. The results obtained in silico demonstrated that sesquiterpene γ-lactones and their derivatives inhibit the SARS-Cov-2 spike protein and proteases, as well as the angiotensin-converting enzyme 2. The identified molecules can be considered as candidates for the development of new drugs with antiviral activity on their basis.
