Description

Oxolinic acid is a synthetic quinolone antibiotic. Oxolinic acid is insoluble in water and soluble in dilute alkali solutions.

    CAS Number

    14698-29-4

    Molecular Formula

    C13H11NO5

    Molecular Weight

    261.23

    Mechanism of Action

    Fluoroquinolone antibiotics target bacterial DNA gyrase, an enzyme which reduces DNA strain during replication. Because DNA gyrase is required during DNA replication, subsequent DNA synthesis and ultimately cell division is inhibited.

    Storage Conditions

    2-8°C

    Tariff Code

    2933.49.2600

    Spectrum

    Oxolinic acid targets gram negative bacteria, especially those which cause urinary tract infections.

Applications

    Microbiology Applications

    Oxolinic acid is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:

    • Escherichia coli 0.06 µg/mL – 0.25 µg/mL

    Media Supplements

    Oxolinic acid can be used as a selective agent in several types of isolation media:

    Columbia Blood Agar - Streptococcus Selective Supplement (COBA)

    Plant Biology Applications

    Oxolinic acid has proven to be effective against the seed-borne pathogen Burkholderia glumae which causes grain rot, sheath rot, seedling rot, and bacterial panicle blight. In an experiment performed by Ham et al., oxolinic acid was applied to plants infected by Burkholderia glumae. In the group treated with oxolinic acid, 97% of the plants were successfully treated in contrast to the 8% which survived the untreated control group.
