Description and Uses

Umifenovir is a broad-spectrum antiviral agent. It inhibits the replication of H5N1 influenza (IC₅₀ = 30 μg/ml) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro (IC₅₀ = 3.537 μM). Umifenovir inhibits entry of hepatitis C virus (HCV) pseudoparticles in Huh7 cells (IC₅₀ = 6 μg/ml) and inhibits Zika virus protein synthesis in Vero cells. In vivo, umifenovir (45 mg/kg) reduces the formation of influenza-induced lung lesions in ferrets.

Arbidol hydrochloride (ARB) is a small monocular compound. It is used to prevent severe pneumonia and virus-associated cytokine dysregulation induced by influenza viruses (IFV). ARB also possesses some immunomodulatory properties, including the effects of interferon induction and macrophage activation.
Arbidol is a broad-spectrum antiviral that has demonstrated activity against a number of enveloped and non-enveloped viruses, and is used clinically to treat influenza. Arbidol inhibits viral entry into host cell and stimulates immune response. Arbidol inhibits fusion between the viral capsid and the cell membrane of the target cell, thus preventing viral entry.
