High-Content Screening of Thai Medicinal Plants Reveals Boesenbergia rotunda Extract and its Component Panduratin A as Anti-SARS-CoV-2 Agents

Abstract: Since December 2019, the emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has caused severe pneumonia, a disease named COVID-19, that became pandemic and created an acute threat to public health. The effective therapeutics are in urgent need. Here, we developed a high-content screening for the antiviral candidates using fluorescence-based SARS-CoV-2 nucleoprotein detection in Vero E6 cells coupled with plaque reduction assay. Among 122 Thai natural products, we found that Boesenbergia … Show more

“…Hydroxychloroquine, a classical anti-malarial drug, had no inhibitory effect against SARS-CoV-2 infection in human lung epithelial cells (IC50>50 µM) ( Figure 2C and 2D), while niclosamide, a classical anti-helminthic drug, inhibited SARS-CoV-2 infection with the IC50 of 0.90 µM (Figure 2E and 2F). Of note, hydroxychloroquine can exhibit antiviral effect in Vero E6 cells 30 but not Calu-3 human lung epithelial cells. 31 These results were consistent to previous reports 31,32 and supported the validity of Calu-3-based anti-SARS-CoV-2 assay used in this study.…”

“…SARS-CoV-2 virus was isolated from nasopharyngeal swabs of a confirmed COVID-19 patient in Thailand (SARS-CoV-2/01/human/Jan2020/Thailand). The virus was propagated in Vero E6 cells as previous described 30 and stored at -80°C. Viral titration as TCID50 titer/mL was performed in the 96-well plate.…”
