    Abstract:
    A series of 6-substituted-1-aryl-4-oxo-1,4-dihydronicotinic acids were synthesised as monocyclic analogues of the quinolones. The 6-(2-aryl-1-methylethenyl)- and of the 6-(2-arylethenyl)-substituted compounds were shown to possess antibacterial properties that correlate with DNA gyrase inhibitory activity. Differently from the quinolones the antimicrobial activity of the compounds of this study is predominantly against Gram positive strains. The structure-activity relationships ascertained for these monocyclic compounds differ from those established for the quinolones.
