The invention relates to derivatives of glycopeptide and lipoglycopeptide antibiotics possessing an altered ionization state with respect to the parent glycopeptide or lipoglycopeptide antibiotic, and having the ability to be regenerated as the parent glycopeptide or lipoglycopeptide antibiotic under physiological conditions. These compounds are useful as antibiotics for the prevention and/or the treatment of bacterial infections.
