A number of new 4(1H)-quinazolinones were synthesized and evaluated in the carrageenin-induced paw edema test. Most of the compounds were obtained by the cyclization of the appropriately substituted anthranilamides with acid chlorides, followed by further chemical transformation. Structure-activity data suggest that 2-isopropyl-1-phenyl-, 2-cyclopropyl-1-phenyl-, and 1-isopropyl-2-phenyl-4(1H)-quinazolinones afford optimal potency and the presence of a halogen atom is preferred for activity. Adrenalectomy does not affect the antiinflammatory test results. The best result taking into account both efficacy and side effects was displayed by 1-isoproyl-(2-fluorophenyl)-4(1H)-quinazolinone.

Reactions of 2-(substitued-amino)benzamide (1) with ethyl chloroformylformate (2), ethyl chloroformylacetate (3), and ethyl 2-chloroformylpropionate (4) gave 1-substituted 4(1H)-quinazolinones (5,6,and 7, respectively) having an ethoxycarbonyl group on th
