NSAIDs bearing structural resemblance to the aminoalcohol ester class of anticholinergics were specially designed and synthesized. Besides blocking the acidic carboxyl group to overcome the local gastric irritation, the anticholinergic activity was incorporated with the expected advantage of reducing the gastric toxicity by decreasing gastric acid secretions and motility. Derivatives of naproxen and
为了克服与使用普通非甾体抗炎药 (NSAIDs) 相关的局部胃部毒性,专门设计和合成了一些结构与氨基醇酯类抗胆碱能药相似的 NSAIDs 氨基醇酯。除了阻断酸性羧基以克服局部胃刺激外,抗胆碱能活性还具有通过减少胃酸分泌和运动来降低胃毒性的预期优势。合成了萘普生和6-甲氧基-2-萘乙酸(6-MNA)的衍生物。在缓冲液中的水解研究表明,大多数化合物在 80% 的人血清中足够稳定,具有高酶敏感性。大多数衍生物对乙酰胆碱表现出相当好的抗胆碱能作用,显着降低溃疡形成,同时保留母体药物的抗炎效力。抗炎和抗胆碱能活性的结合,同时降低酸性特征,可能会导致开发出比母体 NSAID 更好的化合物,用于长期口服抗炎治疗。
