Structure-activity relationship studies indicated that the antibacterial potency was better when the 6,8-substituents were fluorine atoms and the 7-substituent was either 1-imidazolyl, 20, or 4-methyl-1-imidazolyl, 25. From the results of studies on pharmacokinetic profile and toxicity, 20 and 25 were found to possess excellent antibacterial activities and to show high blood levels after oral administration
制备了一系列6-氟-和6,8-二氟-7-(唑取代的)-1,4-二氢-4-氧代-3-喹啉羧酸。结构活性关系研究表明,当6,8-取代基是氟原子,而7-取代基是1-咪唑基20或4-甲基-1-咪唑基25时,抗菌效果更好。在药代动力学和毒性研究中,发现20和25具有出色的抗菌活性,并且对低毒性小鼠口服后显示出较高的血药浓度。
