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
