商品描述

Pefloxacin is a synthetic fluoroquinolone antibiotic.

TOKU-E offers two forms of pefloxacin: pefloxacin (P015) and pefloxacin mesylate dihydrate (P004). Pefloxacin is slightly soluble in aqueous solution at 11.4 mg/mL. Pefloxacin mesylate dihydrate is freely soluble in aqueous solution.

    CAS Number

    149676-40-4

    Molecular Formula

    C17H20FN3O3 · CH4O3S •2H2O

    Molecular Weight

    465.49

    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

    2933.59.3600

    Spectrum

    Pefloxacin is a broad spectrum antibiotic which targets a wide range of gram positive and gram negative organisms including a few Mycoplasma species.
