The proposed study is an attempt to determine antibacterial activity of synthesized novel 1-substituted-3-(4-oxo-2-phenylquinazolin-3(4H)-yl) urea and thiourea analogues as potent antibacterials against against S. aureus and E. coli bacteria.


Reagents used in the present study were of synthetic grade and solvents were used after distillation. Novel quinazolinone analogues were synthesized by considering substitution pattern, characterization of the synthesized analogues was performed using various techniques like Thin layer chromatography, Melting point, Infrared spectroscopy, Proton NMR spectrometry and Mass spectrometry.



Six derivatives of quinazolinone analogues were synthesized. The structures of 1-substituted-3-(4-oxo-2-phenylquinazolin-3(4H)-yl) urea and thiourea derivatives were confirmed by physical and spectral analysis. The compounds were assayed for antibacterial activity against S. aureus and E. coli using ciprofloxacin as standard. The synthesized analogues have shown good yield and comparable antibacterial activity.



The present study delivers a convenient and efficient protocol for the quinazolinone analogues synthesis.


Keywords: KeywordsAntibacterial, Quinazolinone analogues, S. aureus, E. coli. Ciprofloxacin
