    Studies on Quinolone Antibacterials. IV. Structure-Activity Relationships of Antibacterial Activity and Side Effects for 5- or 8-Substituted and 5,8-Disubstituted-7-(3-amino-1-pyrrolidinyl)-1-cyclopropyl-1,4-dihydro-4-oxoquinoline-3-carboxylic Acids.
    摘要:
    一系列带有各种取代基(H、F、Cl、Me、OH、OMe、OEt)的 7-(3-氨基-1-吡咯烷基)-1-环丙基-1, 4-二氢-4-氧代喹啉-3-羧酸,OCH2F,OCHF2,OCF3,SMe)在C-8位被制备并评估其对标准实验室菌株和对喹诺酮类药物(例如环丙沙星(CPFX,1)和氧氟沙星(OFLX,2))耐药的细菌的体外抗菌活性。临床分离株。 8-甲基 (8a)、8-氟 (9a)、8-氯 (10a) 和 8-甲氧基 (12a) 化合物对革兰氏阳性菌和革兰氏阴性菌的作用比 CPEX (1) 强 4 倍。但这四种化合物在浓度为100μg/ml时就会对哺乳动物细胞的染色体造成损伤。接下来,制备了一系列在C-5位具有各种取代基(H、Cl、Me、NH2、NHMe、NMe2)的喹诺酮类药物,并评价其抗菌活性和对染色体的损伤作用。我们发现5-氨基-8-甲基化合物(8d)表现出很强的抗菌活性(8d的体外抗菌活性对革兰氏阳性菌和革兰氏阴性菌均比CPFX(1)强4倍),减少对染色体的损伤,并降低喹诺酮类毒性(在豚鼠(静脉注射)剂量为 30 mg/kg 时无光毒性,在小鼠中与芬布芬以 100 mg/kg 剂量共同给药时无惊厥诱导活性) (ip))。
