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.

How to use
In Vitro:
The efficacy of Triazavirin against the tick-borne encephalitis virus is estimated in the sensitive cell culture. In a concentration of 128 mcg/mL Triazavirin is shown active in inhibition of the tick-borne encephalitis virus reproduction (strain Sofiin) by accumulation in the SKEV cell culture.
In Vivo:
The therapeutic efficacy Triazavirin against experimental Forest-Spring encephalitis on albino mice is studied. The results shows that in high doses (200-400 mg/kg) Triazavirin moderately protects the infected animals. A significant increase of the animal lifespan in the test groups (from 4.1 to 4.8 days) and a statistically valid decrease of the virus accumulation in the target organ are observed.
