A series of 4-substituted 4-(1H-1,2,3-triazol-1-yl)piperidine building blocks was synthesized and introduced to the C7 position of the quinolone core, 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylic acid, to afford the corresponding fluoroquinolones in 40–83% yield. The antibacterial activity of these new fluoroquinolones was evaluated using a standard broth microdilution
合成了一系列的4-取代的4-(1 H -1,2,3-三唑-1-基)哌啶构件,并将其引入到喹诺酮核心的C7位7-氯-1-环丙基-6-氟-4-氧代-1,4-二氢-1,8-萘啶-3-羧酸,以40-83%的产率提供相应的氟喹诺酮类。使用标准肉汤微稀释技术评估了这些新的氟喹诺酮类药物的抗菌活性。其中,喹诺酮1-环丙基-6-氟-7-(4-(4-甲酰基-1 H -1,2,3-三唑-1-基)哌啶-1-基)-4-氧代-1 ,4-二氢-1,8-萘啶-3-羧酸(34.15)对喹诺酮敏感和耐多药菌株,特别是对金 黄色葡萄球菌和表皮葡萄球菌与环丙沙星和万古霉素相比。
