Azaribine (triacetyl-6-azauridine) is a drug which was developed for the treatment of psoriasis,[1] and also has anti-cancer and antiviral actions.[2][3] It is a prodrug which is metabolised to the nucleoside analogue 6-azauridine in the body. Azaribine was approved for clinical use in treatment of psoriasis,[4] but subsequently withdrawn because of toxicity issues,[5][6] however it continues to be researched as a potential agent for the treatment of emerging viral diseases.[7]
