1-乙基-6-氟-1,4-二氢-4-氧代-7-(4-芳酰硫代氨甲酰基-1-哌嗪基)-3-喹啉羧酸的合成及抗菌作用
SYNTHESIS AND ANTIBACTERIAL ACTION OF 1-ETHYL-6-FLUORO-1, 4-DIHYDRO- 4-OXO-7-(4-AROYLTHIOCARBAMOYL-1 -PIPERAZINYL)- 3-QUINOLINE CARBOXYLIC ACIDS
【摘要】 <正> 1-乙基-6-氟-1,4-二氢-4-氧代-7-(1-哌嗪基)-3-喹啉羧酸(氟哌酸,norfloxacin),因有抗菌谱广、抗菌活性强等优点而引起人们广泛的兴趣,但尚有排泄快、生物利用度低等缺点。鉴于众多芳酰基硫脲衍生物有抗真菌、抗病毒和抗细菌等广谱生物活性,设想将芳
【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 μg/ml.
