The present invention provides novel glycopeptides antibiotic derivatives.
These glycopeptide antibiotic derivatives are characterized in that a sugar residue (I) represented by the formula:
(wherein n is an integer of 1 to 5; Sugs are each independently a monosaccharide, (Sug)n is a divalent sugar residue formed by binding of same or different 1 to 5 monosaccharides; RA1 is optionally substituted lower alkyl, optionally substituted lower alkenyl, or optionally substituted cycloalkyl; and RE is OH or NHAc (Ac is acetyl))
is bound to an aromatic ring of the fourth amino acid residue in the glycopeptide skeleton.
These derivatives have antibacterial activity against vancomycin-resistant bacteria.
