MedKoo CAT#: 330050

CAS#: 928659-17-0 (sodium hydrate)

Description: Riamilovir, also known as Triazavirin, is an antiviral drug candidate. Tiazavirin is a broad-spectrum antiviral drug developed in Russia. It has a novel triazolotriazine core, which represents a new structural class of non-nucleoside antiviral drugs. It was originally developed as a potential treatment for pandemic influenza strains such as H5N1, and most of the testing that has been done has focused on its anti-influenza activity. However triazavirin has also been found to have antiviral activity against a number of other viruses including Tick-borne encephalitis virus, and Forest-Spring Encephalitis virus, and is also being investigated for potential application against Lassa fever and Ebola virus disease. In February 2020, testing of triazavirin was started against SARS-CoV-2.
