The synthesis and structure-activity relationships of transition-state renin inhibitors containing the homostatine analogues at the scissile bond are described. These inhibitors incorporate the amino acid side chains corresponding to positions 7-12 (P4-P2') of angiotensinogen. Ethyl, 2-hydroxyethyl and 3-hydroxypropyl groups at position 2 of the homostatine analogues (P1') are more effective for increasing potency than the isopropyl group. A combination of residues at P1, P3 and P4 is important for potency and this result auggests that S1, S3 and S4 form a huge hydrophobic core together in renin.
描述了含有在切割键处的同胺酸类似物的过渡态肾素抑制剂的合成及其结构-活性关系。这些抑制剂包含了与血管紧张素原第7-12位(P4-P2')相对应的氨基酸侧链。在同胺酸类似物的第2位(P1')上的乙基、2-羟乙基和3-羟丙基比异丙基更有效地增加了效力。P1、P3和P4位点的氨基酸残基组合对效力很重要,结果表明S1、S3和S4在肾素中共同形成了一个巨大的疏水核心。
