[2-(2,6-dichloro-phenylamino)-phenyl]-acetate, a new diclofenac derivative bearing a benzofuroxan heterocyclic moiety in its structure, was prepared by the reaction of sodium diclofenac and 5-bromomethyl-benzo[1,2,5]oxadiazole 1-oxide. Pharmacological characterization of this modified diclofenac maintained the anti-inflammatory activity similar to its parent compound assayed in vitro and in vivo. The
制备了1-氧-苯并[1,2,5]恶二唑-5-基甲基[2-(2,6-二氯-苯基氨基)-苯基]-乙酸酯,一种新的双氯芬酸衍生物,其结构中带有苯并呋喃基杂环部分双氯芬酸钠和5-溴甲基-苯并[1,2,5]恶二唑1-氧化物的反应。这种修饰的双氯芬酸的药理学特性与其体外和体内测定的母体化合物保持相似的抗炎活性。尽管抑制了前列腺素E 2的胃内含量,但用该修饰化合物未观察到天然双氯芬酸的致溃疡性质。更好的胃耐受性似乎与一氧化氮释放能力有关。
