Beschreibung
Vancomycin is a glycopeptide antibiotic identified for its utility in the treatment of gram-
positive bacteria, including penicillin-
resistant staphylococci. It acts by binding to bacterial cell wall protein precursors, interfering with continuing protein synthesis. Vancomycin resistance in staphylococcal species has recently emerged as a clinical issue.
Chemische Eigenschaften
off white powder
Verwenden
Vancomycin hydrochloride is the salt of a glycopeptide antibiotic isolated from Amycolatopsis orientalis in 1956. Vancomycin exhibits potent activity against Gram positive bacteria and is highly effective against MRSA in vitro and in vivo. Vancomycin interferes with cell wall synthesis by binding to D-alanine-D-alanine residues.
Allgemeine Beschreibung
The isolation of the glycopeptide antibiotic vancomycin(Vancocin, Vancoled) from Streptomyces orientalis (renamedA. orientalis) was described in 1956 by McCormick et al.232The organism originally was obtained from cultures of anIndonesian soil sample and subsequently has been obtainedfrom Indian soil. Vancomycin was introduced in 1958 as anantibiotic active against Gram-positive cocci, particularlystreptococci, staphylococci, and pneumococci. It is not activeagainst Gram-negative bacteria, with the exception ofNeisseria spp. Vancomycin is recommended for use wheninfections fail to respond to treatment with the more commonantibiotics or when the infection is known to be caused by aresistant organism. It is particularly effective for the treatmentof endocarditis caused by Gram-positive bacteria.
Vancomycin hydrochloride is a free-flowing, tan tobrown powder that is relatively stable in the dry state. It isvery soluble in water and insoluble in organic solvents. Vancomycin inhibits cell wall synthesis by preventingthe synthesis of cell wall mucopeptide polymer. It does soby binding with the D-alanine-D-alanine terminus of theuridine diphosphate-N-acetylmuramyl peptides requiredfor mucopeptide polymerization.236 Details of the bindingwere elucidated by the elegant NMR studies of Williamson.
