Abstract

5-Substituted analogs of the ribavirin heterocyclic base showed significant antiviral activity against SARS-CoV2 together with reduced toxicity, compared to ribavirin. Using the SARS-CoV2 attachment model, it was found that 5-(pyridin-4-yl)-1,2,4-triazole-3-carboxamide and 5-(tetrahydrofuran-2-yl)-1,2,4-triazole-3-carboxamide, as well as the isosteric derivative of the latter, namely, 5-(tetrahydrofuran-2-yl)-1,2,4-triazole-3-carbothioamide could act through inhibiting viral attachment to the cell.
