[1] Arbidol was found to have potent inhibitory activity against enveloped and non-enveloped RNA viruses, including FLU-A, RSV, HRV 14, and CVB3, when added before, during, or after viral infection, with IC50 values ranging from 2.7 to 13.8 mg/mL. Selective antiviral activity was shown against the DNA virus AdV-7 only when it was added after infection (therapeutic index (TI) = 5.5).
[2] In MDCK cultures infected with influenza A/PR/8/34, Arbidol induced changes in viral mRNA synthesis for the PB2, PA, NP, NA, and NS genes. [3] Arbidol interacts with membrane phospholipids and alters their physicochemical properties, with significant effects on negatively charged phospholipids but less effects on zwitterionic phospholipids. Arbidol is located at the membrane interface and participates in hydrogen bonding with water or phospholipids or both, reducing the hydrogen bonding network of phospholipids and producing a phospholipid phase similar to a dehydrated solid.
