Title: Polyacid glycopeptide derivatives
Abstract:Disclosed are derivatives of glycopeptides that are substituted at the C-terminus with a substituent that comprises two or more (e.g. 2, 3, 4, or 5) carboxy (CO.sub.2 H) groups; and pharmaceutical compositions containing such glycopeptide derivatives. The disclosed glycopeptide derivatives are useful as antibacterial agents.
