General description

6-Azauridine is a pyrimidine nucleoside analog.

Application

6-Azauridine (AzUrd) blocks the conversion of orotic acid into UMP and it is used in antiviral studies.
6-Azauridine has been used:
  • in uridine monophosphate synthase (UMPS) activity assay
  • as an antiviral agent to study its inhibition effect and cytotoxic potential on foot and mouth disease virus
  • to screen for anticryptosporidial activity
  • in the pretreatment of HeLa cells to study its effect on inhibition of cellular uridine synthesis before and during chase with 5-bromouridine 5′-triphosphate (BrUTP)
  • as a reference compound for comparing the antiviral activity and cytotoxic activity against viral host cell lines

Biochem/physiol Actions

6-azauridine is a prodrug, upon conversion to 6-aza-UMP, inhibits uridine monophosphate synthase (UMPS). It is a broad spectrum anti-metabolite. It interferes with pyrimidine biosynthesis and affects the cellular nucleic acid levels. It is considered as a antineoplastic metabolite. It inhibits RNA viruses like chikungunya virus, semliki forest virus, and human coronavirus. It significantly inhibits the growth of Cryptosporidium parasites.

Human coronavirus NL63 (HCoV-NL63), a recently discovered member of the Coronaviridae family, has spread worldwide and is associated with acute respiratory illness in young children and elderly and immunocompromised persons. Further analysis of HCoV-NL63 pathogenicity seems warranted, in particular because
