Abstract

Drug repositioning is the only feasible option to immediately address the COVID-19 global challenge. We screened a panel of 48 FDA-approved drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which were preselected by an assay of SARS-CoV. We identified 24 potential antiviral drug candidates against SARS-CoV-2 infection. Some drug candidates showed very low 50% inhibitory concentrations (IC50s), and in particular, two FDA-approved drugs-niclosamide and ciclesonide-were notable in some respects.

Keywords: COVID-19; FDA-approved drug; SARS-CoV-2.

(A) Dose-response curve analysis by immunofluorescence for reference drugs. The blue squares represent inhibition of SARS-CoV-2 infection (%), and the red triangles represent cell viability (%). The confocal microscope images show cell nuclei (red) and viral N protein (green) at each drug concentration. Means ± SD were calculated from duplicate experiments. (B) Dose-response curve analysis by immunofluorescence for 45 drugs that were tested in this study. The blue squares represent inhibition of SARS-CoV-2 infection (%), and the red triangles represent cell viability (%). Means ± SD were calculated from duplicate experiments.
