Repurposing the Combination Drug of Favipiravir, Hydroxychloroquine and Oseltamivir as a Potential Inhibitor Against SARS-CoV-2: A Computational Study
Pooja Yadav, Papia Chowdhury
doi:10.21203/rs.3.rs-628277/v1
The virus SARS-CoV-2 has created a situation of global emergency all over the world from the last few months. We are witnessing a helpless situation due to COVID-19 as no vaccine or drug is effective against the disease. In the present study, we have tested the repurposing efficacy of some currently used combination drugs against COVID-19. We have tried to understand the mechanism of action of some repurposed drugs:Favipiravir (F), Hydroxychloroquine (H) and Oseltamivir (O). The ADME analysis have suggested strong inhibitory possibility of F, H, O combination towards receptor protein of 3CL pro of SARS-CoV-2 virus. The strong binding affinity, number of hydrogen bond interaction between inhibitor, receptor and lower inhibition constant computed from molecular docking validated the better complexation possibility of F+H+O:3CL pro combination. Various thermodynamical output from Molecular dynamics (MD) simulations like potential energy (Eg), temperature (T), density, pressure, SASA energy, interaction energies, Gibbs free energy (ΔGbind) etc., also favored the complexation between F+H+O and CoV-2 protease. Our in-silico results have recommended the strong candidature of combination drugs Favipiravir, Hydroxychloroquine and Oseltamivir as a potential lead inhibitor for targeting SARS-CoV-2 infections.
