A series of 7-(3-amino- or 3-aminomethyl-1-pyrrolidinyl)-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-o xo-3-quinolinecarboxylic acids was synthesized and tested for antibacterial activity. Unique to these quinolones was the presence of a methyl or phenyl group in the pyrrolidine ring. Although the in vitro activity of these agents was usually equal to or less than that of their unsubstituted counterparts
合成了一系列7-(3-氨基-或3-氨基甲基-1-吡咯烷基)-1-环丙基-6,8-二氟-1,4-二氢-4-邻xo-3-喹啉羧酸,并进行了测试抗菌活性。这些喹诺酮的独特之处是吡咯烷环中存在甲基或苯基。尽管这些药物的体外活性通常等于或小于其未取代的对应物,但一种喹诺酮7- [3-(氨基甲基)-3-甲基-1-吡咯烷基] -1-环丙基-6,8-二氟-1,4-二氢-4-氧代-3-喹啉羧酸,在体外和体内均显示出非凡的效力,尤其是针对革兰氏阳性生物。
