Abstract:
A series of disubstituted 4(3H) quinazolines were designed for potential application in tumors. Firstly, N-benzoyl anthranilic acid is formed, which undergoes cyclization in the presence of pyridine. Subsequently, nucleophilic attack by semicarbazide on the carbonyl carbon gives 2-substituted 3-carbamido 4(3H) quinazolones, which gives final compound with appropriate substitution. The final as well as intermediate products were confirmed by NMR, FT-IR, and mass spectrometry. In vitro toxicity was performed with different cell lines and showed that the connection of hydrophilic styryl to quinazoline moiety increases its efficacy.
