  摘要：

  A series of 5,7-disubstituted 1-cyclopropyl-6,8-difluoro-4(1H)-oxoquinoline-3-carboxylic acids (10-36) were prepared; the C-5 substituent in these compounds comprised halo, hydroxy, mercapto, and amino groups and the C-7 functional group included variously substituted piperazines. In vitro antibacterial screening results indicated that the amino group was optimal among the C-5 substituents. A combination of the C-5 amino group and the C-7 3,5-dimethylpiperazinyl appendage in this series conferred the best overall antibacterial property with lack of adverse drug interactions. Compound 36k [named sparfloxacin, originally AT-4140, 5-amino-1-cyclopropyl-6,8-difluoro-7-(cis-3,5-dimethyl-1-piperazinyl)- 4(1H)-oxoquinoline-3-carboxylic acid] was superior to ciprofloxacin in both in vitro and in vivo potency and hence was selected as a promising candidate for an improved therapeutic agent.

  6-fluoro-7-substituted-1,4-dihydro-4-oxoquinoline-3-carboxylic acids have been prepared. At the N-1 position "standard" substitution was employed with the ethyl, cyclopropyl, and p-fluorophenyl groups being used. At C-7 the introduction of some novel piperazines was made. Most notably, 2-(fluoromethyl)piperazine (10) and hexahydro-6-fluoro-1H-1,4-diazepine (16, fluorohomopiperazine) at the quinolone C-7 position

  已经制备了一些新颖的6-氟-7-取代的1，4-二氢-4-氧代喹啉-3-羧酸。在N-1位置，使用“标准”取代，使用乙基，环丙基和对氟苯基。在C-7中，引入了一些新颖的哌嗪。最值得注意的是，喹诺酮C-7位的2-（氟甲基）哌嗪（10）和六氢-6-氟-1H-1,4-二氮杂卓（16，氟高哌嗪）产生的产品具有与环丙沙星参考品相似的体外抗菌活性。1-环丙基-6-氟-7- [3-（氟甲基）哌嗪基] -1,4-二氢-4-氧喹啉-3-羧酸（20）的体内疗效优于环丙沙星（20） 2）。
