We modified the preparative-scale method for the synthesis of 2-aryl 1,2-dihydro-4(3H)-quinazolinone derivatives obtained in high yields by the reaction of new and commercially available aromatic aldehydes with anthranilic acid amides. A series of quinazolinone derivatives possessing anticancer and antiparasitic activities, as well as capable of preventing the progress of neurodegenerative diseases

A combinatorial synthesis of 3-arylideneaminoquinazolin-4(1H)-one derivatives is described by a reaction of 2-aminobenzohydrazides with two equivalents of aldehydes or ketones in ionicliquidscatalyzed by iodine. Controlling the reaction temperature or reducing the activity of the substrates, respectively, the intermediate products of hydrazones were obtained first, and then they were applied to react

3-dihydroquinazolin-4(1H)-ones by use of hydrazine hydrate and ethidene diamine as nitrogen source. The antibacterial activity was investigated using minimum inhibitory concentration (MIC) method against four bacterial strains. Tests have shown that these derivatives have potential activity against Streptococcus lactis. The structure–activity relationship of the antibacterial activity evaluation was
