    Area of Science:

    • Virology
    • Medicinal Chemistry
    • Pharmacology

    Background:

    • Antiviral drug development is crucial due to the constant emergence of new viral threats.
    • Over 200 analogues of purines and pyrimidines have demonstrated efficacy in inhibiting viral DNA and RNA replication.
    • Existing antiviral therapies have varying degrees of effectiveness and specific applications.

    Purpose of the Study:

    • To review the current landscape of antiviral compounds.
    • To highlight the efficacy of specific antiviral agents against particular viral infections.
    • To discuss the potential and limitations of emerging antiviral therapies.

    Main Methods:

    • Literature review of antiviral compounds.
    • Analysis of efficacy data for various antiviral agents.

    Related Experiment Videos

  • Assessment of clinical applications and limitations of studied antivirals.

    • Main Results:

    • Adenine arabinoside is highly effective against disseminated herpes simplex virus and herpes zoster.
    • Idoxuridine is a valuable treatment for herpetic keratitis.
    • Amantadine shows utility in preventing A2 influenza, but its efficacy against swine flu is unproven.
    • Methisazone is effective for smallpox prevention and vaccinia complication management.

    Conclusions:

    • A range of antiviral compounds, particularly nucleoside analogues, offer therapeutic benefits for viral diseases.
    • Interferon's clinical use is limited by its short half-life and high cost, hindering near-term availability.
    • Continued research into novel antiviral agents is essential for combating viral infections effectively.
