  Novel amino-substituted 3-quinolinecarboxylic acid antibacterial agents: synthesis and structure-activity relationships

  摘要：

  A series of novel 3-quinolinecarboxylic acid derivatives have been prepared and their antibacterial activity evaluated. These derivatives are characterized by fluorine attached to the 6-position and substituted amino groups appended to the 1- and 7-positions. Structure-activity relationship studies indicate that antibacterial potency is greatest when the 1-substituent is methylamino and the 7-substituent is either 4-methyl-1-piperazinyl, 16, or 1-piperazinyl, 21. Derivatives 16 and 21, the 1-methylamino analogues of pefloxacin and norfloxacin, respectively, show comparable in vitro and in vivo antibacterial potency to these two known agents. The activity (vs. Escherichia coli Vogel) of 16 (amifloxacin) is the following: in vitro MIC (microgram/mL) = 0.25; in vivo (mice) PD50 (mg/kg) = 1.0 (po), 0.6 (sc).

  Novel 1-R-1,4-dihydro-4-oxo-6-fluoro-7-(Z.dbd.N--)-quinolinecarboxylic acids and esters thereof, where R is amino, lower-alkylamino, 2-propenylamino or di-lower-alkylamino, R" is hydrogen or lower-alkyl, and Z.dbd.N is a heterocyclic group, useful as antibacterial agents, are prepared by reacting the corresponding 7-chloroquinoline derivatives with the appropriate heterocyclic compound, Z.dbd.NH. A preferred group of compounds are those where Z.dbd.N is 1-piperazinyl or 4-lower-alkyl-1-piperazinyl.

  1-R-1,4-二氢-4-氧代-6-氟-7-(Z.dbd.N--)-喹啉羧酸及其酯类，其中R为氨基，低烷基氨基，2-丙烯基氨基或二-低烷基氨基，R"为氢或低烷基，Z.dbd.N为杂环基团，可用作抗菌剂，通过将相应的7-氯喹啉衍生物与适当的杂环化合物Z.dbd.NH反应制备而成。其中，首选化合物组是Z.dbd.N为1-哌嗪基或4-低烷基-1-哌嗪基。

  A series of N-(1-aziridinyl)quinoline-3-carboxylic acid derivatives (e.g. 11a-f, 20a-g, 21a-d) have been synthesized by insertion reaction of nitrenes (e.g. ethyl 7-chloro-6-fluoro-1-nitreno-1,4-dihydro-4-oxoquinoline-3-carboxylate (9)) into double bond of different olefins (e.g. styrene (10a), see Schemes 2 and 4). The nitrenes were formed in situ by oxidation of N-aminoquinolin-4(1H)-one derivatives (8, 18a,b) using Pb(OAc)(4) as oxidizing agent.
