A series of new triazole derivatives of quinazolin‐4(3H)‐one and new oxadiazole derivatives of quinazolin‐4(3H)‐one were synthesized. The newly synthesized compounds were characterized by IR, 1H NMR, 13C NMR and mass spectral data. All the newly synthesized compounds were screened for antibacterial activity against Staphylococcus aureus, Bacillus subtilis (gram‐positive bacteria), Escherichia coli, Pseudomonas aeruginosa (gram‐negative bacteria), and antifungal activity was carried out against Candida albicans and Aspergillus niger.

A series of novel 2,4,6‐trisubstituted quinazoline derivatives were synthesized starting from 2‐amino‐5‐bromobenzoic acid. The structures of the newly synthesized compounds were established by IR, 1H NMR, 13C NMR, and mass spectral data. All the compounds were tested for antimicrobial activity.
