  Synthesis and Antibacterial Evaluation of Certain Quinolone Derivatives

  摘要：

  A number of 7-substituted quinolone derivatives were synthesized and evaluated for antibacterial and cytotoxic activities. Preliminary results indicated that most compounds tested in this study demonstrated better activity against methicillin-resistant Staphylococcus aureus than norfloxacin. Among them, 1-(4-amino-2-fluorophenyl)-6-fluoro-1,4-dihydro-7-{4-[2-(4-methoxyphenyl)-2-hydroxyiminoethyl]-1-piperazinyl}-4-oxo-3-quinolinecarboxylic acid (11d) and its ketone precursor 10d exhibited significant activities against Klebsiella pneumoniae, methicillin-resistant S. aureus, erythromycin- and ampicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus faecalis. Due to strong cytotoxicities of lid (a mean log GI(50) of -5.40), compound 10d, with good antibacterial activities and low cytotoxicities (a mean log GI(50) of -4.67), is a more potential drug candidate.

  A number of fluoroquinolone derivatives were synthesized and evaluated for antimycobacterial activity. Preliminary results are (1) for 1-aryl fluoroquinolones, 1-(4-nitrophenyl) derivatives were inactive while their 1-(2-fluoro-4-nitrophenyl) counterparts were active anti-TB agents (3a vs 4a; 3b vs 4b) indicated the fluoro substituent at C-2 position is important. For the 1-(2-fluoro-4-nitrophenyl)quinolones

  Certain 1-ethyl- and 1-aryl-6-fluoro-1,4-dihydroquinol-4-one derivatives were synthesized and evaluated for antimycobacterial and cytotoxic activities. Preliminary results indicated that, for 1-aryl-6-fluoroquinolones, both 7-(piperazin-1-yl)- and 7-(4-methylpiperazin-1-yl) derivatives, 9b and 11a, are able to completely inhibit the growth of M. tuberculosis at a concentration of 6.25 μg/ml, while

  合成了某些1-乙基和1-芳基-6-氟-1,4-二氢喹啉-4-酮衍生物，并评估了其抗分枝杆菌和细胞毒性的活性。初步结果表明，对于1-芳基-6-氟喹诺酮类化合物，7-（哌嗪-1-基）-和7-（4-甲基哌嗪-1-基）衍生物9b和11a均能够完全抑制生长。的结核分枝杆菌在6.25微克/ ml的浓度，而7- [4-（2-氧代-2-苯乙基）哌嗪-1-基]衍生物13所仅表现出31％的生长抑制在相同的浓度。对于1-乙基-6-氟喹诺酮类化合物，7- [4-（2-氧代丙基）哌嗪-1-基]-和7- [4-（2-氧代-2-苯基乙基）哌嗪-1-基]衍生物，2a和2b分别显示出完全的抑制作用，而它们的2-亚氨基乙基和取代的苯基对应物3a和2c的活性较低。另外，6,8-二氟衍生物比其6-氟衍生物（2b vs. 2d）是更有利的抑制剂。这些结果值得特别关注，因为2a，2b，9b和11a在100μM的浓度下无细胞毒性。此外
