title: [Synthesis and antibacterial action of 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(4-aroylthiocarbamoyl-1-piperaziny l)-3-quinoline carboxylic acids].
abstract: Thirteen new 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(4-aroyl-thiocarbamoyl-1-piperazinyl)-3- quinoline carboxylic acids were prepared. Their structures were characterized by elemental analysis, IR, HNMR and MS spectra. Preliminary pharmacological tests indicated that some of compounds Ia-m possess strong inhibiting activity against Escherichia coli, Bacillus subtilis and Proteus at concentration of 100 micrograms/ml.
