摘要:
Novel glycopeptide antibiotic derivatives. These derivatives are represented by the formula (aglycon part of glycopeptide antibiotic derivative)-(Sac-NH)—RA [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 RA represents, e.g., the formula —X1—Ar1—X2—Y—X3—Ar2 (wherein X1, X2, and X3 each represents 1) a single bond or 2) a heteroatom or heteroatom-containing group selected from the group consisting of —N═, ═N—, —NR1—, —O—, etc.; Y represents —NR2CO— or —CONR2— (wherein R2 represents hydrogen or lower alkyl), etc.)]. These derivatives have antibacterial activity against vancomycin-resistant bacteria.
