A number of 7-substituted-1-tert-butyl-6-fluoroquinolone-3-carboxylic acids and 7-substituted-1-tert-butyl-6-fluoro-1,8-naphthyridine-3-carboxylic acids have been prepared and tested for antibacterial activities. Among those the 7-aminopyrrolidinyl 20b and the 7-diazabicyclo naphthyridine 18b are the most potent compounds in vitro and in vivo. Physicochemical data and acute toxicity are also discussed
已经制备了许多7-取代的1-叔丁基-6-氟喹诺酮-3-羧酸和7-取代的1-叔丁基-6-氟-1,8-萘啶-3-羧酸。经测试具有抗菌活性。其中7-氨基吡咯烷基20b和7-二氮杂双环萘啶18b是体外和体内最有效的化合物。还讨论了理化数据和急性毒性。考虑到体外和体内的微生物活性,低毒性和药代动力学特征,化合物18b BMY 40062表现出最有利的总体性能,并被选择用于临床评估。
