Research Article: c-Met inhibitor NVP-BVU972 induces antiviral protection and suppresses NF-?B-mediated inflammation

Date Published: 2025-08-29

Abstract:
Inhibiting viral replication and limiting NF-?B-driven inflammation simultaneously is essential for better antiviral therapy, highlighting the urgent need for a single agent that achieves both functions. Here, we reported NVP-BVU972 (NVP), a selective c-Met inhibitor, induced a robust antiviral state and inhibited NF-?B-mediated inflammation. The dual functions blocked replication of diverse RNA viruses (VSV, EMCV, MHV) and DNA viruses (HSV-1, VACV) and reduced systemic cytokine levels (Il1?, Il6, Tnf?) in vitro and in vivo. Mechanistically, we identified NVP reprogrammed inflammation-related loci by modulating both gene expression and chromatin accessibility, and chaetocin inhibition of H3K9 methylation reversed its antiviral activity. These findings unveil NVP as a promising host-directed agent that simultaneously limits viral propagation and reduces inflammation, and suggest repurposing NVP as a broad-spectrum antiviral.
