NO-PAW inhibited the cytopathic effect in lung epithelial cells. (A–F) Cytopathic effect (CPE) was detected in MRC-5 cells, 7 days after exposure to HCoV-229E virus, at the indicated infectious viral titers. (G) The average log TCID50/mL value of three independent experiments is presented. (H) The graph indicates the log order of change in viral TCID50, at indicated NO-PAW concentrations.
