active renin inhibitors (compounds V, VI, and XVII) with high specificity for renin and a remarkable stability against chymotrypsin. Replacement of the amide bond between P2 and P3 by isosteres (ketomethylenes, hydroxyethylenes, and the corresponding thio-insertion analogues) led to compounds (VIII-XIII, XVIII, and XIX) with renin inhibitory activity in the nanomolar range. Oral activity was achieved by
在ACHPA或Leu psi [CHOHCH2] Val基四肽的P2位置掺入β-丙氨酸或γ-氨基丁酸可提供高度活性的肾素抑制剂(化合物V,VI和XVII),对肾素具有高特异性,并且对胰凝乳蛋白酶的稳定性显着。用等排物(酮亚甲基,羟基乙烯和相应的硫代插入物类似物)取代P2和P3之间的酰胺键,得到的化合物(VIII-XIII,XVIII和XIX)的肾素抑制活性在纳摩尔范围内。通过在含β-丙氨酸的四肽的N-末端掺入极性官能团来获得口服活性。选择了这些化合物之一(XXVIII)进行进一步研究。这种抑制剂在对食蟹猴静脉和口服给药后显示出优异的功效和长效作用。
