The synthesis of different compounds with a quinazolinone, quinazolinthione, or quinazolinimine skeleton and their in vitro biologicalevaluation as inhibitors of inducible and neuronal nitric oxide synthase (iNOS and nNOS) isoforms are described. These derivatives were obtained from substituted 2‐aminobenzylamines, using diverse cyclization procedures. Furthermore, the diamines were synthesized by

Previously we reported the potent anticonvulsant activity of 3-dimethylamino-3,4-dihydro-2(1H)-quinazolinone. In this report, a series of 3-alkyl-3,4-dihydro-2(1H)-quinazolinones was synthesized in three steps from isatoic anhydrides or an anthranilic acid. Structure/activity investigations revealed optimal activity for the 3-isopropyl and 3-cyciohexyl analogs. These compounds were effective against
