Synthesis, characterization and in vitro Antimicrobial activity of some 1-(substitutedbenzylidene)‎-4-(4-(2-(methyl phenyl)‎-4-oxoquinazolin-3 (4h)‎-yl)‎ phenyl)‎ semicarbazide derivatives

الملخص EN

A series of substitutedbenzylidene)-4-(4-(2-(methyl/phenyl)-4-oxoquinazolin-3(4H)-yl) phenyl)semicarbazide derivatives were synthesized with the aim of developing potential antimicrobials.

It was characterized by FT-IR, 1H NMR, Mass spectroscopy and elemental analysis.

In addition, the in vitro antibacterial and antifungal properties were tested against some human pathogenic microorganisms by employing the disc diffusion technique and agar streak dilution method.

All title compounds showed activity against the entire strain of microorganisms.

The relationship between the functional group variation and the biological activity of the evaluated compounds were well discussed.

Based on the results obtained, compound 5j was found to be very active compared to the rest of the compounds which were subjected to antimicrobial assay.
