An in-silico study on selected organosulfur compounds as potential drugs for SARS-CoV-2 infection via binding multiple drug targets

The emerging paradigm shift from ‘one molecule, one target, for one disease’ towards ‘multi-targeted small molecules’ has paved an ingenious pathway in drug discovery in recent years. We extracted this idea for the investigation of drugs for COVID-19. Perceiving the importance of organosulfur compounds, seventy-six known organosulfur compounds were screened and studied for the interaction with multiple SARS-CoV-2 target proteins by molecular dynamics simulation. Lurasidone and its derivatives displayed substantial binding affinity against five proteins (Mpro, PLpro, Spro, helicase and RdRp). The pharmacokinetics, ADMET properties and target prediction studies performed in this work further potentiates the effectiveness against SARS-CoV-2.
