The 1-(5-fluoro-2-pyridyl) or 1-(3-fluoro-4-pyridyl) group was introduced in the syntheses of new pyridonecarboxylic acid antibacterial agents. 1-(5-Fluoro-2-pyridyl)-6-fluoro-1,4-dihydro-7-(4-methyl-1-piperazinyl)-4-oxoquinolone-3-carboxylic acid 7b (DW-116) showed a moderate in vitro antibacterial activity but it was found to have very excellent pharmacokinetic profiles so that 7b (DW-116) showed dramatic
将1-(5-氟-2-吡啶基)或1-(3-氟-4-吡啶基)基团引入新的吡啶酮羧酸抗菌剂的合成中。1-(5-氟-2-吡啶基)-6-氟-1,4-二氢-7-(4-甲基-1-哌嗪基)-4-氧喹诺酮-3-羧酸7b(DW-116)显示体外抗菌活性中等,但发现它具有非常出色的药代动力学特征,因此7b(DW-116)的体内功效显着提高。
