preparing the following four amino acid prodrugs of 5-ASA: 5-(N-L-aspartylamino)-2-salicylic acid, disodium salt (18), 5-(N-L-glutamylamino)-2-salicylic acid, disodium salt (19), [(5-aminosalicyl)-L-prolyl]-L-leucine, sodium salt (25), and [[5-(N-L-glutamylamino)salicyl]-L-prolyl]-L-leucine, disodium salt (28). In these compounds, the peptide bond is selectively split by the intestinal brush border aminopeptidase
5-氨基水杨酸(5-ASA)是许多用于治疗炎症性肠病(例如克罗恩氏病和溃疡性结肠炎)的制剂的有效成分,但其功效受到早期吸收和代谢的限制。通过制备以下5种ASA的4种氨基酸前体药物,研究了利用刷状边缘酶(如氨肽酶A和羧肽酶)的选择性水解活性的可能性:5-(NL-天冬氨酰胺基)-2-水杨酸,二钠盐(18 ),5-(NL-谷氨酰胺基氨基)-2-水杨酸,二钠盐(19),[(5-氨基水杨基)-L-脯氨酰] -L-亮氨酸,钠盐(25)和[[5-(NL -谷氨酰胺基)水杨基] -L-脯氨酰基] -L-亮氨酸二钠盐(28)。在这些化合物中,肽键会被肠刷缘氨基肽酶A选择性分裂(化合物18、19,
