REVIEW Two metabolites (metabolites 1 and 2; 2 to 3% of total teicoplanin) have been isolated after intravenous administration of radiolabeled teicoplanin. After purification, their structures were found to be new teicoplanin-like molecules, bearing 8-hydroxydecanoic and 9-hydroxydecanoic acyl moieties. This metabolic transformation is likely due to hydroxylation in the omega-2 and omega-1 positions for metabolites 1 and 2, respectively, of the C-10 linear side chain of component A2-3. This might explain the low extent of metabolism of teicoplanin if we consider that only component A2-3 has a linear chain that is susceptible to such oxidation.
