in vivo antibacterial activity. In order to identify the structures of the metabolites of grepafloxacin, 17 possible metabolites were prepared. Among them, 6 compounds were found to be actual metabolites (2a, b, 4a, b and 6a, b) of grepafloxacin in rats, dogs and/or humans. The antibacterial activities of these metabolites were found to be weaker than that of grepafloxacin.
格雷帕沙星(1-环丙基-1,4-二氢-6-氟-5-甲基-7-(3-甲基-1-哌嗪基)-4-氧代-3-喹啉-羧酸,OPC-17116)(1)在体外和体内表现出有效和广谱的抗菌活性。为了鉴定格列沙星代谢物的结构,制备了17种可能的代谢物。其中,发现有6种化合物是大鼠,狗和/或人类中格列氟沙星的实际代谢产物(2a,b,4a,b和6a,b)。发现这些代谢物的抗菌活性弱于格列氟沙星。
