2-Pyridone quinoline hybrids as potent antibacterial and antifungal agents

261-266An efficient synthetic strategy for the synthesis of 6-amino-1-(((2-chloroquinolin-3-yl)methylene)amino)-2-oxo-4-(aryl)-1,2-dihydropyridine-3,5-dicarbonitriles is well described in this paper. Structures of synthesized compounds have been identified by standard spectroscopic techniques like 1H NMR, 13C NMR, IR and mass spectroscopy. Results of the biological activity reveals that electron withdrawing groups and presence of –OH group on meta position play a significant role for the increment in the antibacterial and antifungal activities respectively of 3a-j. In the present study, it has been observed that compounds 3i and 3e are the most active antimicrobials
