Teicoplanin Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Teicoplanin is a new antibiotic, the second glycopeptide to be developed in over 30 years. Compared with vancomycin, the only such agent currently available, teicoplanin is equiefficacious, and has milder side-effects and a longer half-life, allowing once-daily dosing and bolus injection. Teicoplanin is claimed to have an overall cure rate of 92% in infections involving skin, joint and bone, endocaditis and septicemia.

• Verwenden

  Teicoplanin complex is family of closely related metabolites produced by Actinoplanes teichomyceticus. Teicoplanin complex possesses potent broad spectrum antibiotic activity against Gram positive bacteria, including MRSA and E. faecalis. The metabolites share a common glycopeptide core (teicoplanin A-3) on which a family of fatty acids varying in length, degree of saturation and branching are linked as amides through one of the aminoglycoside moieties. The major component of the complex is teicoplanin A2 which itself has five major components (teicoplanin A2-1 to A2-5) and four minor components (teicoplanin RS-1 to RS-4).

• Allgemeine Beschreibung

  Teicoplanin (Teichomycin A2, Targocid) is a mixture offive closely related glycopeptide antibiotics produced bythe actinomycete Actinoplanes teichomyceticus. The teicoplanin factors differ only in the acyl group inthe northernmost of two glucosamines glycosidicallylinked to the cyclic peptide aglycone. Another sugar, Dmannose,is common to all of the teicoplanins. Thestructures of the teicoplanin factors were determined independentlyby a combination of chemical degradationand spectroscopic methods in three different groupsin 1984.
  The teicoplanin complex is similar to vancomycin structurallyand microbiologically but has unique physical propertiesthat contribute some potentially useful advantages.While retaining excellent water solubility, teicoplanin has significantlygreater lipid solubility than vancomycin. Thus, teicoplaninis distributed rapidly into tissues and penetratesphagocytes well. The complex has a long elimination halflife,ranging from 40 to 70 hours, resulting from a combinationof slow tissue release and a high fraction of protein bindingin the plasma (～90%). Unlike vancomycin, teicoplanin isnot irritating to tissues and may be administered by intramuscularor intravenous injection. Because of its long half-life, teicoplaninmay be administered on a once-a-day dosing schedule.Orally administered teicoplanin is not absorbedsignificantly and is recovered 40% unchanged in the feces.
  Teicoplanin exhibits excellent antibacterial activity againstGram-positive organisms, including staphylococci, streptococci,enterococci, Clostridium and Corynebacterium spp.,Propionibacterium acnes, and L. monocytogenes. It is not activeagainst Gram-negative organisms, including Neisseriaand Mycobacterium spp. Teicoplanin impairs bacterial cellwall synthesis by complexing with the terminal D-alanine-Dalaninedipeptide of the peptidoglycan, thus preventing crosslinkingin a manner entirely analogous to the action ofvancomycin.

• Clinical Use

  Antibacterial agent.

• Stoffwechsel

  Teicoplanin is excreted almost entirely by glomerular filtration in the urine, as unchanged drug. Two metabolites are formed probably by hydroxylation and represents 2-3% of the administered dose. Unchanged teicoplanin is mainly excreted by the urinary route while 2.7% of the administered dose is recovered in feces (via bile excretion) within 8 days following administration.
