Biological Activity

[Description]:

Triazavirin (Riamilovir sodium dihydrate) is a broad-spectrum antiviral agent targeting influenza viruses, lassa virus, TBEV and Ebola virus; suppresses the replication of influenza virus in cell culture and in chicken chorioallantoic membranes, and protects mice from death caused by type A and B influenza viruses.

[Target]

Nucleoside analogue; Influenza virus[1]


[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[2].

[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[3].
