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
合成了许多氟喹诺酮衍生物,并评估了其抗分枝杆菌活性。初步结果是(1)对于1-芳基氟喹诺酮类药物,1-(4-硝基苯基)衍生物是无活性的,而它们的1-(2-氟-4-硝基苯基)对应物是抗结核药物(3a vs 4a; 3b vs 4b) )表明在C-2位的氟取代基很重要。对于1-(2-氟-4-硝基苯基)喹诺酮类化合物,分别具有97%和98%抑制作用的7-哌啶基衍生物4a和7-(3,5-二甲基哌嗪基)衍生物4e比7的活性更高。 -吗啉基,7-(4-甲基哌嗪基)和7-哌嗪基同类物,分别为4b,4c和4d。此外,
