The present invention relates to novel coumarin quinolone carboxylic acids wherein the pyridone system is fused in 3,4-, 6,7- and 7,8-positions of the coumarin system, of the general formula I
wherein
R1R2 = -NHCH=C(CO2R6)CO-, R3 = NO2 or NH2, R4 = R5 = H, R6 = H or C2H5;
R1R2 = -NHCH=C(CO2R6)CO-, R3 = R4 = H, R5 = F, R6 = H or C2H5;
R1R2 = -CO(CO2R6)C=CHNH-, R3 = R4 = R5 = H, R6 = H or C2H5;
R1R2 = R3R4 = -NHCH=C(CO2R6)CO-, R5 = H, R6 = H or C2H5;
R1 = H or OH, R2 = R5 = H, R3R4 = -NHCH=C(CO2R6)CO-, R6 = H or C2H5;
R1 = OH, R2 = R3 = H, R4R5 =-CO(CO2R6)C=CHNH-, R6 = H or C2H5;
R1 = R5 = H, R2 = CH3 or CF3, R3R4 = -CO(CO2R6)C=CHNH-, R6 = H or C2H5,
as well as pharmaceutically acceptable salts thereof.
The object of the invention are also processes for the preparation of novel coumarin quinolone carboxylic acids and the biological action thereof.
