为了寻找高效低毒的非甾体抗炎药物, 将5-氯-2-吲哚酮与氯甲酸苯酯经酯化及水解制得1-苯氧羰基-5-氯-2-吲哚酮, 在4-N,N-二甲氨基吡啶作用下与对甲磺酰基苯甲酰氯反应, 经酸化得1-苯氧羰基-3-[羟基-(p-甲磺酰基)苯甲撑基]-5-氯-2-吲哚酮(II1), 最后与相应的胺(氨)反应, 经盐酸中和制得未见文献报道的目标化合物II2II15, 其结构经IR, 1H NMR, MS和元素分析确证. 二甲苯致小鼠耳肿胀模型测试显示II10, II11, II15具有明显的抗炎活性; 角叉菜胶致大鼠足跖肿胀模型试验结果表明, II10, II11抗炎活性与双氯芬酸钠和替尼达普钠相当(P>0.05); 其中II11的胃肠道副作用显著小于双氯芬酸钠(P<0.05)和替尼达普钠(P<0.01).

In order to search for new compounds with stronger anti-inflammatory activity and less side effects, phenyl 5-chloro-2-oxindole-1-carboxylate, obtained from 5-chloro-2-oxindole via esterification with phenyl chloroformate and subsequent hydrolyzation, reacted with 4-(methylsulfonyl) benzoyl chloride and 4-dimethylaminopyridine, followed by acidification with hydrochloric acid to yield phenyl 5-chloro- 3-(hydroxy-p-methylsulfonylphenylmethylene)-2-oxo-2,3-dihydroindole-1-carboxylate (II1), which was condensed with corresponding amines, followed by acidification with hydrochloride acid to afford the target compounds II2II15, respectively. Fifteen novel title compounds were synthesized, and their structures were confirmed by IR, 1H NMR, MS spectra and elemental analyses. II10, II11 and II15 exhibited marked anti-inflammatory activity in xylene-induced mice ear swelling model. Moreover, II10 and II11 showed significant anti-inflammatory activity comparable to diclofenac sodium and tenidap sodium (P>0.05) in carrageenan-induced rat paw edema model. II11 had less gastrointestinal side effect than diclofenac sodium (p<0.05) and tenidap sodium (P<0.01).
