Ester and amide prodrugs of ibuprofen (1) and naproxen (16) were synthesized and evaluated for anti-inflammatory activity and gastrointestinal toxicity. The chemical structure of the prodrugs was varied in terms of lipophilicity and reactivity toward hydrolysis. Inhibition of acetic acid-induced writhing in mice indicated that prodrugs 7, 15, 19, and 20 exhibited significantly better activity (p less
合成了布洛芬(1)和萘普生(16)的酯和酰胺前药,并评估其抗炎活性和胃肠道毒性。前药的化学结构在亲脂性和对水解的反应性方面有所不同。小鼠中乙酸诱导的扭体的抑制表明前药7、15、19和20表现出比母体化合物明显更好的活性(p小于0.01)。确定大鼠口服1和16以及前药5、18、21和22后在胃粘膜中形成的平均溃疡数。除甘氨酸酰胺21外,所有前药对胃粘膜的刺激性均显着低于1或16。
