Synthesis of Novel 3-[(dialkyl/aryl amino) methyl]-2-Substituted-4(3H)- Quinazolinones and Evaluation of their Anti-Inflammatory Activity

Literature survey reveals that in recent years several Quinazolinone derivatives have been synthesized and reported to possess varied biological and pharmacological properties. They are found to be useful as antibacterial, analgesic, anti-inflammatory, antifungal, anticonvulsant and anticancer agents. A new series of 3- [(di alkyl amino) methyl]-2-substituted-4(3H)-Quinazolinones were synthesized by the reaction of a mixture of 2-substituted-4(3H)-Quinazolinone, formaldehyde and dialkyl or diaryl amine by mannich reaction. The chemical structures of the synthesized compounds were confirmed by IR, mass spectral and C, H, N analysis techniques. The synthesized compounds were screened for anti-inflammatory activity by the carrageenan induced rat hind paw edema method. The synthesized compounds were significantly showed their antiinflammatory activity that of standard.
