CQ significantly decreased viral replication of HCoV-229E at concentrations lower than in clinical usage. CQ affects the activation of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK). p38 MAPK inhibitor, SB203580, inhibits CPE induced by HCoV-229E infection and viral replication.
