The synthetic plasma kallikrein (PK) inhibitor trans-4-aminomethylcyclohexanecarbonylphenylalanine-4-carboxymethylanilide (PKSI-527) consists of three parts. Each part was replaced by analogues in an attempt to improve the potency and the selectivity of PKSI-527. Among the peptides examined, trans-4-aminomethylcyclohexanecarbonylphenylalanine-4-carboxyanilide (peptide 16) inhibited PK with a high selectivity and an IC50 value of 2.7μM, being as potent as PKSI-527.
合成血浆激肽释放酶(PK)抑制剂反式-4-氨基甲基环己烷羰基苯丙氨酸-4-羧甲基苯甲酰胺(PKSI-527)由三个部分组成。尝试用类似物替换每个部分,以提高PKSI-527的效力和选择性。在检测的肽中,反式-4-氨基甲基环己烷羰基苯丙氨酸-4-羧基苯甲酰胺(肽16)对PK具有高度选择性,IC50值为2.7μM,与PKSI-527效力相当。
