  Synthesis and antibacterial evaluation of novel 8-fluoro Norfloxacin derivatives as potential probes for methicillin and vancomycin-resistant Staphylococcus aureus

  摘要：

  A series of novel 8-fluoro Norfloxacin derivatives and the hybrids of its piperazinyl derivatives incorporated with 1,3,5-triazine and pyrimidine were synthesized. All the above compounds were evaluated for their antibacterial activity against Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus and methicillin & vancomycin-resistant S. aureus. Among all, compounds having Morpholine, N-methyl/phenyl/benzyl/pyrimidinyl piperazines and n-butylamine substitution at C-7 position, have shown increased potency in comparison to norfloxacin and ciprofloxacin.

  then acidified with hydrochloric acid afforded the desired 1-(substituted-benzyl)-6-fluoro-1,4-dihydro-4-oxo-7-(1-iperazinyl)quinoline-3-carboxylic acids. The 6,8-difluoro analogs were prepared similarly using 6,7,8-trifluoro-4-hydroxyquinoline-3-carboxylic acid ethyl ester as a starting material. Some of these quinolones demonstrated fairly good antibacterial activities. Among them, 6-fluoro-1-(4-fluorophenylmethyl)-1

  将6,7-二氟-4-羟基喹啉-3-羧酸乙酯与取代的苄基氯烷基化，得到1-（取代的苄基）-6,7-二氟-1,4-二氢-4-氧代喹啉-3-羧酸乙酯。用哌嗪或N治疗吡啶中的-甲基哌嗪产生1-（取代的苄基）-6-氟-1,4-二氢-4-氧代-7-（1-哌嗪基）喹啉-3-羧酸乙酯，将其用氢氧化钠水溶液水解，然后用盐酸酸化，得到所需的1-（取代的苄基）-6-氟-1,4-二氢-4-氧代-7-（1-哌嗪基）喹啉-3-羧酸。类似地，使用6,7,8-三氟-4-羟基喹啉-3-羧酸乙酯作为起始原料制备6,8-二氟类似物。这些喹诺酮类药物中的一些表现出相当好的抗菌活性。其中6-氟-1-（4-氟苯基甲基）-1,4-二氢-7-（1-哌嗪基）-4-氧喹啉-3-羧酸（7d）和6,8-二氟-1-（ 3-氟苯基甲基）-1,4-二氢-7-（1-哌嗪基）-4-氧喹啉-3-羧酸（8c）是最好的两个。
