  • Publication number: 20070021328
    Abstract: Semi-synthetic glycopeptides that have antibacterial activity are based on modifications of a rearranged vancomycin or desmethyl-vancomycin scaffold, in particular, alkylation or acylation of the amino substituent on the amino-substituted sugar moiety on this scaffold with certain acyl groups; and/or conversion of the acid moiety on the macrocyclic ring of this scaffolds to certain substituted amides. Also provided are methods for synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.
