Despite strict measures taken by many countries, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to be an issue of global concern. Currently, there are no clinically proven pharmacotherapies for disease 2019, despite promising initial results obtained from drugs such as azithromycin and hydroxychloroquine. Therefore, the repurposing approved use against SARS-CoV-2 has become a viable strategy. Here, we searched that target 3C-like protease (3CLpro) viral RNA-dependent...
