A facile synthetic method using low-valenttitaniumreagent (TiCl4/Zn system) to promote the novel reductive cyclization of 2-nitrobenzamides and triphosgene is described. Sequentially, a series of quinazoline-2,4-diones were synthesized in good yields.

derivative with promising in vitro activity against Schistosoma mansoni. Follow-up studies of the antischistosomal potential of this candidate are presented here. The in vivo studies in a S. mansoni mouse model show a significant reduction of total worms and a complete disappearance of immature eggs when administered concomitantly with praziquantel in comparison with the administration of praziquantel alone
inhibition pattern. Additionally, antioxidant evaluations exhibited moderate to weak potency in 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The detailed interactions and binding mode toward tyrosinase of the most potent derivative were explicated by molecular dockingstudy. Moreover, the computer-aided drug-likeness and pharmacokinetic studies were also carried out.
