The invention relates to novel chimeric antibiotics of formula I
wherein
R1 represents OH, OPO3H2 or OCOR5;
R2 represents H, OH or OPO3H2;
A represents N or CR6;
R3 represents H or fluorine;
R4 is H, (C1-C3) alkyl, or cycloalkyl;
R5 is the residue of a naturally occurring amino acid, of the enantiomer of a naturally occurring amino acid or of dimethylaminoglycine;
R6 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).
本发明涉及一种新型嵌合抗生素,其
化学式为I,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
