摘要
Background:The outbreak and continued spread of coronavirus infection(COVID-19)sets the goal of finding new tools and methods to develop analytical procedures and tests to detect,study infection and prevent morbidity.Methods:The noncovalent binding of cyanine and squarylium dyes of different classes(60 compounds in total)with the proteases NSP3,NSP5,and NSP12 of SARS-CoV-2 was studied by the method of molecular docking.Results:The interaction energies and spatial configurations of dye molecules in complexes with NSP3,NSP5,and NSP12 have been determined.Conclusion:A number of anionic dyes showing lower values of the total energy Etot could be recommended for practical research in the development of agents for the detection and inactivation of the coronavirus.
