    Chlortetracycline Hydrochloride, USP

    Chlortetracycline hydrochloride (HCl) is tetracycline antibiotic and the first antibiotic of the tetracycline class to be discovered. Chlortetracycline HCl is soluble in water at 8.6 mg/mL.

    Mechanism of ActionThe mechanism of chlorotetracycline involves entering a cell and binding to the 30s ribosomal subunit preventing peptide elongation and ultimately inhibiting protein synthesis. Resistance to chlortetracycline can be a result of inactivation by cell enzymes or pumping the antibiotic out of the cell upon entering.
    SpectrumChlortetracycline is a broad spectrum antibiotic targeting a wide variety of gram positive and gram negative bacterial cells.
    Microbiology ApplicationsChlortetracycline HCl 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:

    • Micrococcus 17 µg/mL

    Plant Biology ApplicationsChlortetracycline, in combination with colistin and gentamicin have been successfully used in sweet cherry (Prunus avium L). tissue culture to eliminate Pseudomonas spp. contaminants.
    Molecular FormulaC22H23ClN2O8· HCl
