A variety of quinazolinone derivatives were successfully synthesized, via a three-component condensation reaction between anthranilic acid, acetic anhydride, and amines. This process was accomplished in the presence of catalytic amount of titanium dioxide nanoparticles (nano-TiO2), under solvent-free conditions. The synthesized compounds were evaluated for their vasorelaxant activity as they revealed a range of activities on the isolated thoracic rat aorta.
