Synthesis of 2,3-disubstituted-2,3-dihydroquinazolin-4(1H)-one derivatives catalyzed by dodecylbenzenesulfonic acid was carried out in 80-92% yields at 40-42 °C within 1-2 h in aqueous media via one-pot three-component condensation of isatoic anhydride, aromatic aldehyde and amine under ultrasound irradiation. Convenient work-up procedures, mild reaction conditions, avoiding the use of organic solvents

disease. Therefore, continuous research is an urgent need so as to discover novel therapeutic alternatives. Objective: The development of safer and more efficient therapeutic anti-T. cruzi drugs continues to be a major goal in trypanocidal chemotherapy. Method: Synthesis, 2D-QSAR and drug-like physicochemical properties of a set of quinazolinone and quinazolinederivatives were studied as trypanocidal
