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
