Pneumonia caused by the COVID-19 virus has led to quick search of drugs that would able to block the spread of this virus. A standard way of drug development is a long process. One approach that can significantly accelerate drug development is drug reposition. In this study a virtual screening of the database of approved drugs has been used for search inhibitors against 3СLpro COVID-19, the main protease of COVID-19. Molecular docking, simulation of molecular dynamics and binding energy estimation by MM-GBSA method allowed to select several compounds for further experimental testing. The most promising drugs are the HIV protease inhibitor Indinavir, the inhibitor of protease hepatitis C Telaprevir, the antiulcer drug Dalargin, and the ErB receptor tyrosine kinase inhibitor Neratinib
