Identification of potential inhibitors of coronavirus SARS-CoV-2 using the methods of virtual screening and molecular modeling

To find small-molecule compounds that can simulate the structural and functional properties of the high affinity X77 ligand of the main protease of SARS-CoV-2 - etiologic agent of COVID-19, the virtual screening of 9 molecular libraries of the Pharmit web server containing over 213.5 million chemical structures was performed. Using molecular modeling, the neutralizing activity of the identified molecules was evaluated, resulting in 5 leader compounds promising for synthesis and testing for antiviral activity. The data obtained indicate that these compounds may be used as basic structures for the development of effective drugs to treat the novel coronavirus infection.
