The invention relates to novel chimeric antibiotics of formula I
wherein
R
1
represents OH, OPO
3
H
2
or OCOR
5
;
R
2
represents H, OH or OPO
3
H
2
;
A represents N or CR
6
;
R
3
represents H or fluorine;
R
4
is H, (C
1
-C
3
) alkyl, or cycloalkyl;
R
5
is the residue of a naturally occurring amino acid, of the enantiomer of a naturally occurring amino acid or of dimethylaminoglycine;
R
6
represents H, alkoxy or halogen; and
n is 0 or 1;
and to salts (in particular pharmaceutically acceptable salts) of compounds of formula I.
These chimeric compounds are useful in the manufacture of medicaments for the treatment of infections (e.g. bacterial infections).
该发明涉及公式I的新型嵌合抗生素,其中R1代表OH、OPO3H2或OCOR5;R2代表H、OH或OPO3H2;A代表N或CR6;R3代表H或氟;R4是H、(C1-C3)烷基或环烷基;R5是天然氨基酸、天然氨基酸的对映体或二甲氨基甘氨酸的残基;R6代表H、烷氧基或卤素;n为0或1;以及公式I化合物的盐(特别是药学上可接受的盐)。这些嵌合化合物在制造用于治疗感染(例如细菌感染)的药物时很有用。
