    Summary

    This study investigated two interferon inducers, polyguacyl and double-strand RNA (dsRNA), for antiviral activity. Optimal administration routes were identified for influenza and tick-borne encephalitis, correlating with interferon production and protective effects.

    Area of Science:

    • Virology
    • Immunology
    • Pharmacology

    Context:

    • Interferon inducers are crucial for antiviral therapies.
    • Understanding the pharmacokinetics of these inducers is vital for efficacy.
    • Previous studies have explored various synthetic and natural compounds.

    Purpose:

    • To evaluate the antiviral efficacy of synthetic polyguacyl polynucleotide and natural double-strand RNA (dsRNA).
    • To determine the influence of administration route on interferon induction and circulation.
    • To correlate interferon production with protective effects against experimental viral infections.

    Summary:

    • Two Soviet interferon inducers, polyguacyl and dsRNA, were studied for their antiviral properties.
    • Interferon accumulation and circulation varied based on the administration route (intranasal, intraperitoneal, aerosol).
    • Maximum protection against influenza was achieved with intranasal polyguacyl/dsRNA 4 hours pre-inoculation.
    • Significant protection against tick-borne encephalitis was observed with intraperitoneal administration or aerosols.
    • A direct correlation was established between interferon production levels and the observed protective effect.

    Impact:

    • Identifies optimal administration strategies for specific viral infections.
    • Highlights the importance of route-dependent pharmacokinetics for interferon inducer therapy.
    • Provides a basis for developing more effective interferon-based antiviral treatments.
