N(4)-hydroxycytidine Chemical Properties,Usage,Production

Description

EIDD-1931 is a ribonucleoside analog with antiviral activity. 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). 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. 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.

Uses

EIDD 1931 is an orally bioavailable broad-spectrum antiviral that inhibits SARS-CoV-2 and other multiple endemic, epidemic and bat coronavirus and has the potential for seasonal and pandemic influenza treatment. A broad-spectrum ribonucleoside analog inhibitor of influenza and respiratory syncytial viruses.

Definition

ChEBI: N(4)-hydroxycytidine is a nucleoside analogue that is cytidine which carries a hydroxy group at the N(4)-positon. It has broad-spectrum antiviral activity against influenza, SARS-CoV , SARS-CoV-2 and MERS-CoV. It has a role as a drug metabolite, a human xenobiotic metabolite, an anticoronaviral agent and an antiviral agent. It is a nucleoside analogue and a ketoxime. It is functionally related to a cytidine.

storage

Store at -20°C
