    Study Notes

    Drugs that Inhibit/Disrupt Bacterial Synthesis of DNA and RNA

    • Rifampin, metronidazole, and fluoroquinolones (like ciprofloxacin) prevent or interfere with DNA and RNA production in bacteria.
    • These drugs target bacterial processes involved in DNA and RNA synthesis, ultimately inhibiting bacterial replication.

    Antimetabolites

    • Trimethoprim and sulfonamides are examples of antimetabolites that interfere with specific bacterial metabolic processes.
    • These drugs create dysfunctional metabolic products or reduce the production of essential metabolic products, hindering bacterial growth.

    Drugs that Suppress Viral Replication

    • Many antiviral drugs target enzymes essential for viral replication.
    • These enzymes include DNA polymerase, reverse transcriptase, protease, integrase, and neuraminidase.
    • By inhibiting these enzymes, antiviral drugs effectively suppress viral replication.

    Drugs that Inhibit/Disrupt Bacterial Synthesis of DNA and RNA

    • Rifampin, metronidazole, and fluoroquinolones (like ciprofloxacin) inhibit bacterial replication by targeting DNA and RNA production or interfering with their function.

    Anitmetabolites

    • Trimethoprim and sulfonamides disrupt bacterial metabolism, resulting in reduced growth or the production of dysfunctional metabolic products.
