The present invention provides new derivatives of 4- or 5-aminosalicylic acid, and a pharmaceutical composition containing these derivatives of 4- or 5-aminosalicylic acid as active ingredients, useful for the treatment of intestinal diseases such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) and for the prevention/treatment of colon cancer. More particularly, these derivatives comprise a hydrogen sulfide releasing moiety linked via an azo, an ester, an anhydride, a thioester or an amide linkage to a molecule of 4- or 5-aminosalicylic acid. Furthermore, the present invention provides a process for preparing these compounds and their use for treating IBD and IBS and the prevention/treatment of colon cancer.
本发明提供了4-或5-氨基水杨酸的新衍生物,以及含有这些4-或5-氨基水杨酸衍生物作为活性成分的药物组合物,用于治疗肠道疾病,如炎症性肠病(IBD)和肠易激综合征(IBS),以及预防/治疗结肠癌。更具体地说,这些衍生物包括通过偶氮键,酯键,酸酐键,硫酯键或酰胺键连接到4-或5-氨基水杨酸分子的硫化氢释放基团。此外,本发明提供了制备这些化合物的方法以及它们用于治疗IBD和IBS以及预防/治疗结肠癌的用途。
