Despite intensive global efforts, no approved antiviral therapy with these dual functions has yet been developed, representing a significant gap in current COVID-19 treatment strategies. In this study, we identify BAY 11-7082 (BAY) as a dual–action compound that inhibits SARS-CoV-2 replication and the production of virus-induced proinflammatory cytokines and chemokines, including IL-6, IL-8, CXCL1, and CXCL2. BAY predominantly exerts its antiviral activity at the post-entry stage of the viral life cycle. Mechanistically, BAY potentially interacts with SARS-CoV-2 NSP14 and inhibits virus-induced phosphorylation and degradation of IκBα, suppressing NF-κB activation through the IKK-IκBα signaling axis. Furthermore, BAY exhibits potent antiviral activity against multiple SARS-CoV-2 variants of concern (VOCs). Collectively, these findings support the potential of BAY as a dual-action therapeutic candidate, combining antiviral and anti-inflammatory effects, against SARS-CoV-2 and its emerging variants.2026/04/03GSE310278GSM9293285GSM9293287GSM9293286GSM9293289GSM9293288GSM929329020301310278Homo sapiens
