Free article Abstract

The influenza virus poses a significant global health challenge, causing approximately 500,000 deaths annually. Its ability to evade antiviral treatments and vaccine-induced immunity underscores the need for novel therapeutic approaches. Our study identifies cis-aconitate (cis-aco), a mitochondria-derived metabolite, as a potent dual-action agent against influenza, independently of its metabolic derivative, itaconate. Cis-aco impairs viral polymerase activity, resulting in decreased viral mRNA expression and protein synthesis, as observed for the influenza A/Scotland/20/74 (H3N2) strain. This antiviral effect was further confirmed across multiple influenza A and B strains, as well as in ex vivo human airway and lung organotypic models. Beyond its antiviral properties, cis-aco exhibits potent anti-inflammatory effects, disrupting key inflammatory cascades and reducing the secretion of inflammatory mediators. In a mouse model of influenza pneumonia, cis-aco mitigates viral replication, inflammation, and immune cell activation, significantly improving survival. Notably, its efficacy persists even when administered at later stages of infection, when oseltamivir/Tamiflu® is no longer effective. These findings position cis-aco as a promising influenza treatment, combining antiviral and anti-inflammatory benefits within a clinically relevant timeframe.
