Description

Piperacillin is an extended spectrum β-lactam antibiotic and is resistant to many β-lactamases.

TOKU-E offers two forms of piperacillin: piperacillin (P017) and piperacillin sodium (P010). Piperacillin is sparingly soluble in aqueous solution at 0.119 mg/mL. Piperacillin sodium is freely soluble in aqueous solution.

    CAS Number

    59703-84-3

    Molecular Formula

    C23H26N5NaO7S

    Molecular Weight

    539.54

    Mechanism of Action

    β-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to β-lactams is commonly due to cells containing plasmid encoded β-lactamases.

    Storage Conditions

    2-8 C

    Tariff Code

    Spectrum

    Piperacillin is a broad spectrum antibiotic targeting a wide range of susceptible gram positive and gram negative bacteria.

Applications

    Microbiology Applications

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

    • Neisseria spp. 0.015 µg/mL – 32 µg/mL
    • Bacteroides fragilis 0.25 µg/mL - 32 µg/mL
