Hepatitis E Virus (HEV) Inhibitor

SCR007 is a synthetic carbohydrate receptor (SCR) with broad-spectrum antiviral activity. SCR007 inhibits the entry of enveloped viruses across multiple families (Coronaviridae: SARS-CoV-1, SARS-CoV-2, MERS-CoV; Filoviridae: EBOV, MARV; Paramyxoviridae: NiV, HeV) and the glycosylated nonenveloped rotavirus. SCR007 binds viral envelope N-glycans, blocking viral binding to host cells or both binding and membrane fusion. SCR007 exerts prophylactic effects in hACE2 mice infected with SARS-CoV-2. SCR007 can be used for the study and prevention of enveloped virus pandemics.

SCR005 is a synthetic carbohydrate receptor (SCR) with broad-spectrum antiviral activity. SCR005 inhibits the entry of enveloped viruses across multiple families (Coronaviridae: SARS-CoV-1, SARS-CoV-2, MERS-CoV; Filoviridae: EBOV, MARV; Paramyxoviridae: NiV, HeV) and the glycosylated nonenveloped rotavirus. SCR005 binds viral envelope N-glycans, blocking viral binding to host cells or both binding and membrane fusion. SCR005 exerts prophylactic effects in hACE2 mice infected with SARS-CoV-2. SCR005 can be used for the study and prevention of enveloped virus pandemics.

Antiviral agent 77 (Compound 46) is a potent, orally active, blood-brain-barrier permeable antiviral agent. Antiviral agent 77 shows antiviral activity against CedV (EC₅₀: 1.08 μM in the rCedV-Luc reporter assay), NiV-M (EC₅₀: 2.91 μM), NiV-B and HeV.
