EIDD-1931 is a ribonucleoside analog with antiviral activity.[1],[2],[3],[4] It inhibits replication of severe acute respiratory syndrome coronavirus (SARS-CoV) in Vero 76 cells, Middle East respiratory syndrome coronavirus (MERS-CoV) in Calu-3 2B4 cells, and SARS-CoV-2 in Vero cells (IC50s =0.1, 0.15 and 0.3 μM, respectively).[3],[4] It also reduces viral titers of Venezuelan equine encephalitis virus (VEEV) TC-83 in infected Vero cells (EC50 = 0.426 μM) and wild-type and remdesivir-resistant strains of the model CoV mouse hepatitis virus (MHV) in infected DBT cells.[2][4] EIDD-1931 (100 and 400 mg/kg twice per day) reduces lung viral titers in mouse models of respiratory syncytial virus (RSV) and H1N1 influenza A virus infection.[1]
