The invention relates to novel chimeric antibiotics of formula I
wherein
R1 represents OH, OPO3H2 or OCOR5;
R2 represents H, OH or OPO3H2;
R3 represents H or halogen;
R4 is H, (C1-C3)alkyl, or cycloalkyl;
R5 represents piperidin-4-yl or R5 is the residue of a naturally occurring amino acid, of the enantiomer of a naturally occurring amino acid or of dimethylaminoglycine;
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I式化合物,其中R1代表OH、OPO3H2或OCOR5;R2代表H、OH或OPO3H2;R3代表H或卤素;R4为H、(C1-C3)烷基或环烷基;R5代表
哌啶-4-基或R5是自然存在的
氨基酸、自然存在的
氨基酸的对映体或
二甲氨基甘
氨酸的残基;n为0或1;以及I式化合物的盐(特别是药学上可接受的盐)。这些嵌合化合物在制造治疗感染(例如细菌感染)的药物方面是有用的。
