Synthesis and Characterization of Some Novel Coumarin Based 2-Pyridone Heterocycles with their Broad Spectrum Antimicrobial Potency

Full Text PDF


The synthesis of a novel series of 6-((arylidene) amino)-2-oxo-1-((1-(2-oxo-2H-chromen-3-yl) ethylidene) amino)-4-phenyl-1,2-dihydropyridine-3,5-dicarbonitriles 4a-o were synthesized and structures of compounds have been elucidated by IR, 1H NMR, 13C NMR and mass spectral data. Antimicrobial activity was measured against certain strains of bacteria and fungi by serial broth dilution. Evaluation of antimicrobial activity shown that the compounds (4g, 4j, 4k and 4o) were found to be most active against selected bacterial strains and compounds (4d, 4m and 4n) were found to be most active against selected fungal strains.
