2-Methyl-3-aminosubstituted-3H-quinazolin-4-ones (1-2), 2-methyl-3-(substituted-arylidene-amino)-substituted-3H-quinazolin-4-ones (3-10), 2-bromomethyl-3-(substituted-arylidene-amino)-substituted-3H-quinazolin-4-ones (11-18), 2-(5′-pyridin-4-yl-[1,3,4]-oxadiazol-2-yl-sulfanylmethyl)-3-(substituted-arylidene-amino)-substituted-3H-quinazolin-4-ones (19-26), 3-(3-chloro-2-oxo-4-substituted-aryl-azetidin-1-yl)-2-(5-pyridin-4-yl-[1,3,4]-oxadiazol-2-yl-sulfanylmethyl)-substituted-3H-quinazolin-4-ones (27-34) and 3-(4-oxo-2-substituted-aryl-thiazolidin-3-yl)-2-(5-pyridin-4-yl-[1,3,4]-oxadiazol-2-yl-sulfanylmethyl)-substituted-3H-quinazolin-4-ones (35-42) were synthesized in present study. All the compounds exhibited anti-inflammatory activity at the dose 50 mg/kg p.o. varying degree from 16.3 to 36.3% inhibition of oedema. Compound 40 showed same activity at 25, 50 and 100 mg/kg p.o. like standard drugs. The structure of all these newly synthesized compounds was confirmed by their analytical (C, H, N) and spectral (IR and 1H NMR) data.
