prepared. Structure-activity relationship (SAR) studies indicated that the in vitro antibacterial potency was the following order: 1-(1,1-dimethyl-2-fluoroethyl) greater than 1-[1-methyl-1-(fluoromethyl)-2-fluoroethyl] greater than 1-[1,1-(difluoromethyl)-2-fluoroethyl] substituents. In the quinolone series the monofluoro-tert-butyl derivatives were found to possess better in vitro antibacterial activity
制备了一系列新型的N-1-(单-,-(二-和-(三氟叔丁基)喹诺酮)和-萘吡啶类化合物,结构-活性关系(SAR)研究表明,体外抗菌能力是顺序如下:1-(1,1-二甲基-2-氟乙基)大于1- [1-甲基-1-(氟甲基)-2-氟乙基]大于1- [1,1-(二氟甲基)-2-在喹诺酮系列中,发现单氟叔丁基衍生物具有比非氟化叔丁基等效物更好的体外抗菌活性,其中1-氟叔丁基取代衍生物的体内PD50值反映了药代动力学行为和口服吸收不完全。
