A neuropeptide with diverse biological activities
Umifenovir-d6 is intended for use as an internal standard for the quantification of umifenovir by GC- or LC-MS. Umifenovir is a broad-spectrum antiviral agent.1 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).1,2 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.1,3 In vivo, umifenovir (45 mg/kg) reduces the formation of influenza-induced lung lesions in ferrets.4
