The present invention relates to mono- or bicyclic compounds of the general formula
wherein
X1is -S- or -SO-;
R1is hydrogen, halogen or lower alkyl, optionally substituted by halogen ;
R2is hydrogen, hydroxy, amino, lower alkylamino, di-lower alkylamino, optionally substituted lower alkoxy or a group -OP;
OPis an easily hydrolyzable group;
R3is hydrogen, hydroxy, lower alkyl, halogen or a group -OP;
R4is halogen, hydroxy or a group -OP;
R5is hydrogen, cyano, optionally substituted esterified carboxy or optionally substituted amidated (thio)carboxy, optionally substituted alkyl, optionally substituted alkenyl or optionally substituted heterocyclyl;
R6is -NR7-A, -N=B or optionally substituted heterocyclyl, in which R7 is hydrogen or lower alkyl, A is optionally substituted iminoyl, optionally substituted (thio)acyl, optionally substituted esterified carboxy, optionally substituted amidated (thio)carboxy or optionally substituted heterocyclyl and B is optionally substituted alkylidene;
R0is cyano, optionally substituted esterified carboxy or optionally substituted heterocyclyl, or wherein
R0 and R6taken together represent a group
-CO-O-Q-X2-N(R7)-,
wherein
R7is as above, and
X2is (thio)carbonyl or heterocyclyl;
Qis -CH(R8)- or -CH(R8)-W-;
R8is hydrogen or optionally substituted lower alkyl, and
Wis optionally substituted mono-, di-, tri-, tetra- or pentamethylene, provided that when W is monomethylene X2 is other than (thio)carbonyl,
and
pharmaceutically acceptable salts of the mono- or bicyclic compounds of formula I carrying an acidic and/or basic substituent.
These compounds of formula I as well as their pharmaceutically acceptable salts inhibit DNA gyrase activity in bacteria and possess antibiotic, especially antibacterial activity against microorganisms and can be used in the control or prevention of infectious diseases.
