ABSTRACT:
A number of organic compounds obtained by chemical synthesis as model compounds have useful antimicrobial activities. Quinazoline ring is an aromatic benzopyrimidine system; many of its derivatives possess interesting biological activities, such as analgesic, anti-inflammatory, anti-microbial, and anti-tumor. In our study, the biological activity of synthesized quinazoline semicarbazone derivatives were characterized by antimicrobial screening against several gram-positive, gram negative bacteria, and fungus. The purity of the synthesized compounds was characterized by physicochemical properties, such as solubility, melting point, and thin layer chromatography (TLC).Elemental analysis for carbon, nitrogen, hydrogen, and oxygen was performed according to standard procedures. The presence of functional groups was analyzed using FT-IR spectra. Molecular structural information for the compounds was analyzed by 1H-NMR spectroscopy. The wavelengths of maximum absorbance for all the synthesized compounds were measured by UV-Visible spectroscopy. Thereby the chemical structures of the synthesized quinazoline derivatives were confirmed. Antimicrobial screening for all the compounds exhibits characteristic microbial inhibition. A detailed study is in progress to modify the synthetic route, structural activity, and toxicological barriers for the enhanced pharmacological efficiency of synthetic antibiotics.
