  • Description

    Nalidixic acid is a naphthyridone antibiotic similar in structure and mechanism to quinolones.

    TOKU-E offers two forms of nalidixic acid: nalidixic acid (N011) and nalidixic acid sodium salt (N001). Nalidixic acid is sparingly soluble in aqueous solution at 0.1 mg/mL. Nalidixic acid sodium salt is freely soluble in aqueous solution at 50 mg/mL.

    Mechanism of Action

    Nalidixic acid indirectly inhibits proteins synthesis by binding DNA and interfering with enzymes involved in DNA replication and transcription.


    Nalidixic acid is a broad spectrum antibiotic commonly used against bacteria responsible for urinary tract infections.
