Abstract
As a part of systematic investigation of synthesis, characterization and biological activity of several new 2-[(5- substituted amino-1H-indol-1-yl) methyl] quinazolin-4(3H)-one derivatives (7a-h) have been synthesized by series of reactions such as modified Niementowski synthesis, condensation, reduction and derivatization of amino quinazolinone ring system into schiff bases by aromatic aldehydes. The new synthesized compounds were characterized using IR, 1H NMR and Mass spectroscopy together with elemental analysis. All the synthesized products were evaluated for their antibacterial activity against E. Coli MTCC 443, P. Aeruginosa MTCC 1688, S. Aureus MTCC 96 and S. Pyogenus MTCC 442 and antifungal activity against A. Niger MTCC 282. Most of the synthesized compounds exhibited significant anti-bacterial activities.
