title: Anti-inflammatory activity and PGE2 inhibitory properties of novel phenylcarbamoylmethyl ester-containing compounds.
abstract: A variety of 4-(un)substituted phenylcarbamoyl methyl ester-containing compounds 3a-d, 5a-d and 7a-d were synthesized via reaction in N,N-dimethylformamide of (un)substituted chloroacetanilides 2a-d with the potassium salts of ibuprofen (1), naproxen (4) and N-acetylanthranilic acid (6). Moreover, other 4-(un)substituted phenylcarbamoylmethyl ester-containing compounds 10a-d were synthesized via the attack of (un)substituted chloroacetanilides 2a-d on one of the carboxylic acid groups of the potassium salt of 4-(2-carboxyethylcarboxamido)benzoic acid (8)in N,N-dimethylformamide, with subsequent cyclization of the other one giving finally a pyrrolidinone structure. Anti-inflammatory properties of the synthesized compounds were evaluated in vivo utilizing a standard acute carrageenan-induced paw oedema method in rats and the most promising prepared anti-inflammatory active agents were evaluated for ulcerogenic liability in rats using ibuprofen and naproxen as reference standards in both screenings. PGE(2) inhibitory properties of the highly promising anti-inflammatory agents synthesized and low gastric ulcerogenic liabilities were tested with a PGE(2)assay kit technique.
