Product Description
Triazavirin sodium hydrate (TZV, Riamilovir), a nucleoside analogue of nucleic acid, is a broad-spectrum and potent antiviral agent. Its anti-influenza activity has been the main focus of testing since it was first created as a possible treatment for pandemic influenza strains like H5N1. Triazavirin, however, has also been shown to exhibit antiviral activity against several other viruses, such as the Forest-Spring Encephalitis and Tick-borne encephalitis viruses[6]. It is also being researched for possible use against Lassa fever and Ebola virus disease. Triazavirin began to be tested against SARS-CoV-2 in February 2020. Triazavirin functions by preventing genomic fragment replication and the synthesis of viral RNA and DNA. Triazavirin is likewise a useful preventive medication during the influenza transmission stage.
Biological Activity I Assay Protocols (From Reference)
Targets
Nucleoside analogue; Influenza virus
ln Vitro
Triazavirin's effectiveness against the tick-borne encephalitis virus is measured in a sensitive cell culture. Triazavirin is effective in inhibiting the reproduction of the tick-borne encephalitis virus (strain Sofiin) by accumulation in the SKEV cell culture at a concentration of 128 mcg/mL[2].
ln Vivo
Triazavirin's effectiveness as a treatment against experimental Forest-Spring encephalitis in albino mice is investigated. The findings indicate that triazavirin, at high doses (200–400 mg/kg), protects the infected animals in a moderate way. Test groups' animal lifespans increased significantly (from 4.1 to 4.8 days) and there was a statistically significant drop in the amount of virus accumulation in the target organ[3].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
