Opis

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.[1] It inhibits RNA viruses like chikungunya virus, semliki forest virus, and human coronavirus. It significantly inhibits the growth of Cryptosporidium parasites.
