is to reduce the GIT toxicity associated with acute and chronic NSAIDs use. Anti-inflammatory, analgesic as well as ulcerogenic activities of the prepared esters were evaluated in vivo and compared with that of ibuprofen as reference standard in all screenings, involving the carrageenan induced paw oedema model and hot plate method. Most of the synthesized esters showed remarkable analgesic and anti-inflammatory
非甾体类抗炎药(NSAIDs)通常与胃粘膜和肾脏不良反应有关,与前列腺素发挥生理作用的组织中环氧合酶1(Cox1)的抑制有关。这导致我们开发了一组布洛芬酸和甲芬那酸酯,即:4-((4-取代的亚苄基)氨基)苯基2-(4-异丁基苯基)丙酸酯和4-((4-取代的亚苄基)氨基)苯基2-((2,4-二甲基苯基)氨基)苯甲酸酯类似物,其通过将相应的酸与席夫碱[4-(4-取代的亚苄基氨基)苯酚]缩合而合成,其中席夫碱以二环己基碳二亚胺(DCC)为温和脱水剂。主要目的是减少与急性和慢性NSAIDs使用相关的GIT毒性。消炎(药,体内评估了所制备酯的止痛和产溃疡活性,并在所有筛选中与角叉菜胶诱发的爪浮肿模型和热板法进行了比较,并与布洛芬作为参考标准进行了比较。大多数合成的酯显示出显着的止痛和抗炎活性。有趣的是,发现所有化合物在测试条件下都不致溃疡。该证据表明,代表性NSAIDs的羧基功能的修饰导致保留或增强
