Synthesis and pharmacological investigation of some novel 2,3-disubstituted quinazolin-4(3H)-ones as analgesic and antiinflammatory agents.
A series of novel 2-substituted quinazolin-4(3H)-ones have been synthesized by condensing the aromatic primary amine of 2-substituted quinazolines with different aldehydes and ketones. The synthesized compounds were confirmed by their spectral data (IR, NMR and MS) and the purity was ascertained by elemental analysis. When these compounds were evaluated for analgesic and antiinflammatory activities, compounds I-VIII exhibited more potent analgesic activity than diclofenac sodium, while the compounds IV, V, VI and VII exhibited more potent antiinflammatory activity than diclofenac sodium. The activity values were found to be significant as compared to those of controls.
