Teicoplanin is an antibiotic used in the prophylaxis and treatment of serious infections caused by Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and Enterococcus faecalis. It is a glycopeptide antiobiotic extracted from Actinoplanes teichomyceticus, with a similar spectrum of activity to vancomycin. Its mechanism of action is to inhibit bacterial cell wall synthesis. Teicoplanin is marketed by Aventis under the trade name Targocid®.
Additional recommended knowledge
Oral teicoplanin has been demonstrated to be effective in the treatment of pseudomembranous colitis and Clostridium difficile-associated diarrhoea, with comparable efficacy to vancomycin.
Its strength is considered to be due to the length of the hydrocarbon chain.
Teicoplanin is actually a mixture of several compounds, five major (named teicoplanin A2-1 through A2-5) and four minor (named teicoplanin RS-1 through RS-4). All teicoplanins share a same glycopeptide core, termed teicoplanin A3-1 — a fused ring structure to which two carbohydrates (mannose and N-acetylglucosamine) are attached. The major and minor components also contain a third carbohydrate moiety — β-D-glucosamine — and differ only by the length and conformation of a side chain attached to it.
The structures of the teicoplanin core and the side chains which characterize the five major teicoplanin compounds are shown below.
