  ethyl 1-{(3S)-4,4-difluoro-1-[(S)-1-phenylethyl]pyrrolidin-3-yl}cyclopropanecarboxylate 在 5percent Pd/C 盐酸 、 sodium hydroxide 、 二苯基膦叠氮化物 、 水 、 氢气 、 三乙胺 作用下， 以 甲醇 、 乙醇 、 二氯甲烷 、 二甲基亚砜 为溶剂， 反应 0.25h， 生成 5-Amino-7-[(R)-4-(1-amino-cyclopropyl)-3,3-difluoro-pyrrolidin-1-yl]-6-fluoro-1-((1R,2S)-2-fluoro-cyclopropyl)-8-methyl-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid

  Synthesis and Structure−Activity Relationships of 5-Amino-6-fluoro-1-[(1R,2S)-2-fluorocyclopropan-1-yl]-8-methylquinolonecarboxylic Acid Antibacterials Having Fluorinated 7-[(3R)-3-(1-Aminocyclopropan-1-yl)pyrrolidin-1-yl] Substituents

  摘要：

  A series of novel 5-amino-6-fluoro-1-[(1R,2S)-2-fluorocyclopropan-1-yl]-8-methylquinolones bearing fluorinated (3R)-3-(1-aminocyclopropan-1-yl)pyrrolidin-1-yl substituents at the C-7 position (2-4) was synthesized to obtain potent drugs for infections caused by Gram-positive pathogens, which include resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae (PRSP), and vancomycin-resistant enterococci (VRE). These fluorinated compounds 2-4 exhibited potent antibacterial activity comparable with that of a compound bearing a non-fluorinated (3R)-3-(1-aminocyclopropan-1-yl)pyrrolidine moiety at the C-7 position (1) and had at least 4 times more potent activity against representative Gram-positive bacteria than ciprofloxacin (CPFX), gatifloxacin (GFLX), or moxifloxacin (MFLX). Among them, the 7-[(3S,4R)-4-(1-aminocyclopropan-1-yl)-3-fluoropyr-rolidin-1-yl] derivative 3 (=DQ-113), which showed favorable profiles in preliminary toxicological and nonclinical pharmcokinetic studies, exhibited potent antibacterial activity against clinically isolated resistant Gram-positive pathogens.
