Novel glycopeptide antibiotic derivatives. These derivatives are represented by the formula (aglycon part of glycopeptide antibiotic derivative)-(Sac-NH)—R
A
[wherein (aglycon part of glycopeptide antibiotic derivative) is the part formed by removing the sugar part from a known glycopeptide antibiotic derivative; (Sac-NH) part is an amino sugar part or a sugar chain part containing an amino sugar; and R
A
represents, e.g., the formula —X
1
—Ar
1
—X
2
—Y—X
3
—Ar
2
(wherein X
1
, X
2
, and X
3
each represents 1) a single bond or 2) a heteroatom or heteroatom-containing group selected from the group consisting of —N═, ═N—, —NR
1
—, —O—, etc.; Y represents —NR
2
CO— or —CONR
2
— (wherein R
2
represents hydrogen or lower alkyl), etc.)]. These derivatives have antibacterial activity against vancomycin-resistant bacteria.
