    Teicoplanin

    $86.99 - $495.81

    Teicoplanin is a lipoglycopeptide complex first reported from Actinoplanes teichomyceticus in 1978.  Teicoplanin is a mixture of several compounds; 5 major compounds, Teicoplanin A2-1 thru A2-5, and 4 minor compounds, referred to as related substances 1 to 4 or teicoplanin RS1-4.  All teicoplanin compounds share the same glycopeptide core, termed teicoplanin A3-1, a fused ring structure to which two carbohydrates (mannose and N-acetylglucosamine) are attached.  To view related teicoplanin compounds click here.

    Teicoplanin has a similar spectrum of activity as vancomycin and is effective against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and Enterococcus faecalis.

    Teicoplanin is a cell wall synthesis inhibitor that works by inhibiting peptidoglycan synthesis and polymerization in two ways. One mechanism inhibits N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) from coming together to form the peptidoglycan backbone. Another mechanism prevents cross-linking between amino acid residues in the peptidoglycan chain.

    Teicoplanin is sparingly soluble in water.

    Synonyms:Targocid, Teichomycin

    Mechanism of ActionTeicoplanin prevents peptidoglycan synthesis and polymerization by two separate mechanisms. One mechanism prevents N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) from linking together forming the peptidoglycan backbone. The second mechanism prevents cross-linking between amino acid residues in the peptidoglycan chain. This mechanism is nearly identical to vancomycin; however, teicoplanin is considered a safer drug due to its lower nephrotoxicity and ototoxicity.
    Spectrum

    Teicoplanin targets primarily gram-positive bacteria especially those resistant to methicillin. These include the drug resistant superbug, MRSA (Methicillin resistant Staphylococcus aureus) and Enterococcus faecalis. Teicoplanin is effective for treating MRSA infections because it inhibits cell wall synthesis through a different mechanism than β-lactam antibiotics.

    Teicoplanin is similar but not identical to vancomycin in its spectrum of activity. The MICs for most gram-positive bacteria and anaerobes are comparable, but teicoplanin is less active against some strains of Staph. haemolyticus (MIC 16–64 mg/L compared to ≤4 mg/L for vancomycin). Both VanA-type VRE and VISA isolates are also resistant to teicoplanin.

    Impurity ProfileImpurity A| 4-methylpent-3-en-2-one(mesityl oxide)|141-79-7|C6H10O|98.14|
    Microbiology ApplicationsAntimicrobial Susceptibility Testing (AST & MIC) teicoplanin is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram positive microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:
    • Enterococcus faecalis 0.06 μg/mL - 0.25 μg/mL
    • Methicillin-resistant Staphylococcus aureus 0.125 μg/mL - >64 μg/mL
