Abstract
We have designed and synthesized (Z)-2-(5-methyl-2-oxo-2H-chromen-7-yl) oxy)-N’-(2-oxoindolin-3-ylidin) acetohydrazide derivatives by reacting 7-hydroxy-4-methyl-coumarin and substituted isatin to afford 12 substituted coumarin acetohydrazide derivatives. The synthesized compounds of coumarin acetohydrazide derivatives were designed and evaluated to study for their possible interactions as DNA gyrase inhibitors. All the synthesized coumarin acetohydrazide compounds have been characterized by spectral analysis IR, 1H NMR and mass spectroscopy. The compounds have been evaluated for In vitro antibacterial and antifungal activity against S. aureus, B. subtilus, E. coli, P. aeruginosa and fungi C. albicans and A. niger. In case of Gram positive bacteria and Gram negative bacteria Compound P5C, M5C, C5C exhibited significant activity. Compounds P5N, M5N, C5N shown moderate activity. Compound P5C, M5C, C5C shown significant Antifungal activity against C. albicans and A. niger. Compounds P5C, M5C, C5C are found to exert significant antibacterial as well as antifungal activity and can serve as potential compound against infectious diseases in future.
