Syntheses and biological activities of new N1-aryl substituted quinolone antibacterials

A series of quinolones with a systematically varied substitution at the phenyl ring at N1 has been synthesized. Three lipophilicity descriptors (log K, log P, R(m)) and the pK(a) values have been determined as well as the microbiological activity: The MIC

Synthesis and antibacterial activity of 1-(substituted pyrrolyl)-7- (substituted amino)-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acids

Seventeen quinolone compounds characterized by having a fluorine atom at the 6-position, a substituted amino at the 7-position, and a substituted pyrrolyl at the 1-position were synthesized for the first time. The in vitro antibacterial activities of thes

SYNTHESIS OF SOME 1-ARYL-1,4-DIHYDRO-4-OXOQUINOLINE-3-CARBOXYLIC ACIDS AND THEIR ANTIBACTERIAL ACTIVITY

1,4-Dihydro-4-oxoquinoline-3-carboxylic acids VIIIc and VIIId were prepared via their ethyl esters VIIIa and VIIIb, which were obtained by a direct arylation of ethyl 7-chloro-6-fluoro-1,4-dihydro-4-oxoquinoline-3-carboxylate (VIa).When treated with piperazine or N-methylpiperazine compound VIIId yields VIIIe or VIIIf, respectively.Reduction of VIIId, VIIIe, and VIIIf with ferrous sulfate yields VIIIg, VIIIh, and VIIIi respectively.Diazotization and introduction of fluorine into VIIIg using hydrogen fluoride-pyridine yields VIIIj.The compounds prepared were testedfor their antimicrobial activity in vitro.
