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. PGE2 inhibitory properties of the highly promising anti-inflammatory agents synthesized and low gastric ulcerogenic liabilities were tested with a PGE2 assay kit technique.
在 N,N-二甲基甲酰胺中,(未)取代的氯乙酰苯胺 2a-d 与布洛芬 (1)、萘普生 (4) 和 N-乙酰基氨基苯甲酸 (6) 的钾盐反应,合成了多种含 4-(未)取代苯基氨基甲酰甲酯的化合物 3a-d、5a-d 和 7a-d。此外,在 N,N-二甲基甲酰胺中,通过(未)取代的氯乙酰苯胺 2a-d 与 4-(2-羧乙基羧酰胺基)苯甲酸(8)钾盐的一个羧基的反应,合成了其他含 4-(未)取代苯基氨基甲酰甲酯的化合物 10a-d,随后另一个羧基环化,最终得到吡咯烷酮结构。利用标准的急性卡拉胶诱导大鼠爪水肿法对合成化合物的抗炎特性进行了体内评价,并以布洛芬和萘普生作为参照标准,对制备的最有前途的抗炎活性剂的致溃疡性进行了评价。用 PGE2 检测试剂盒技术检测了合成的极具前景的抗炎剂的 PGE2 抑制性和低胃溃疡致病性。
