Molecular Docking, DFT Studies and ADMET Simulations for Evaluating Already Approved FDA Drugs as Inhibitors for SARS-Cov-2 RNADependent Polymerase

Abstract

Background: Remdesivir, a drug in use for Ebola it is already tested in clinical trials phase III. Objective: To evaluate any other possible related structures with similar properties that could be used in clinical trials for COVID-19. Methods: Molecular docking studies, DFT studies, ADMET studies Result: Saquinavir is a chemical structure with similar and even a better chemical activity that drugs that entered clinical trials for Covid-19 Conclusion: Saquinavir should be entered the clinical trials for the treatment of the COVID-19 disease, as it has shown excellent binding affinities to SARS Cov-2 RNA depended polymerase and forms stable complexes with the protein and could possible inhibited its action.
