OBJECTIVES: With the increasing number of people suffering from coronavirus
disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2), there is a dire need to look for effective remedies against this
pandemic. Drug repurposing seems to be the solution for the current situation.
METHODS: In a quest to find a potential drug against this virus, 15 antimalarial
drugs (including chloroquine) and 2413 US Food and Drug Administration-approved
drugs were investigated for activity against both the protease and spike proteins
of SARS-CoV-2 using an in silico approach. Molecular docking analysis followed by
molecular dynamics simulation was performed to estimate the binding and stability
of the complexes. RESULTS: This study identified a single drug - paromomycin -
with activity against two targets of SARS-CoV-2, i.e., spike protein (S1) and
protease domain. Paromomycin was found to have strong binding affinity for both
targets of coronavirus. The results also showed that no antimalarial drug
exhibited effective binding for either S1 or protease. CONCLUSIONS: This study
found that paromomycin may be an effective dual targeting drug against
coronavirus, as it binds not only to the protease domain of the virion, but also
to the spike domain, with high stability. Furthermore, none of the antimalarial
drugs showed strong binding affinity for either protease or the receptor binding
domain (RBD).
