Docking Prediction of Amantadine in the Receptor Binding Domain of Spike Protein of SARS-CoV-2

Amantadine has recently been shown to improve patients with COVID-19. In addition to its known mechanism of actions, we performed docking prediction of this drug on the receptor-binding domain of severe acute respiratory syndrome coronavirus 2, SARS-CoV-2. We hypothesize that such interaction may possibly have contributed a role in the clinical improvements reported.
