Abstract: Quinolone derivs. of formula (I) and their salts are new. In (I), X=N or C-Y; Y=H,F,Cl, methoxy or methyl; Z=H, halogen or amino; R1=C1-4 alkyl, haloalkyl, hydroxyalkyl or alkenyl, C3-6 cycloalkyl, fluoro-substd. phenyl, X-O (or S) CH2CH(CH3)-N, etc.; R2=H or a cation; R3=H or lower alkyl; R4 and R5 each = H, lower alkyl, cycloalkyl or OH; m = 1 or 2. Also claimed is the prepn. of (I) which comprises a condensation reaction of the cpd. of formula (II) and the cpd. of formula (III) at 20-180 deg.C for 1-12 hr(s). The cpds. (I) have a good antibacterial activity.
