Abstract A small library of nitric oxide donating groups, 4-acetamidophenyl-2-[{2-(nitrooxy) ethyl}(phenyl) amino] benzoate (5a–e) possessing a variety of substituents (–H,–NO 2,–CH 3,–acetamidophenyl,–SO 2 NH 2) attached to the fourth position of phenyl ring were synthesized and evaluated for anti-inflammatory, analgesic and ulcerogenic potential. Structure–activity relationship data showed that the 2-phenylaminobenzoic acid skeleton ...
