Ticarcillin disodium is an extended spectrum β-lactam in the carboxypenicillin family.

TOKU-E offers two forms of ticarcillin disodium: ticarcillin disodium (T027) and ticarcillin disodium w/clavulanate potassium (T020). Both forms are freely soluble in aqueous solution. Clavulanate potassium (clavulanic acid) is a β-lactamase inhibitor which can irreversibly inactivate β-lactamase enzymes of β-lactam resistant microbes preventing them from breaking down β-lactam antibiotics. Ticarcillin disodium can be combined with clavulanate potassium for greater efficacy against β-lactam resistant strains.

    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.

    Tariff Code



    Ticarcillin disodium is a broad spectrum antibiotic targeting a wide range of gram positive and gram negative organisms.


    Microbiology Applications

    Ticarcillin disodium 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:

    • Haemophilus influenzae 0.2 µg/mL – 0.8 µg/mL
    • Streptococcus pneumoniae 0.1 µg/mL – 1.6 µg/mL

    Plant Biology Applications

    Timentin is used in Agrobacterium mediated transformations to control Agrobacterium growth. Carbenicillin and cefotaxime can be used in the same applications, however, a study by Nauerby et. al. (1997) found timentin to be less toxic.
