substituted for the amino group and in which the proline residue has been replaced with various hydrophobic amino acids. The compounds were evaluated in vitro for inhibition of angiotensin-converting enzyme and in vivo for antihypertensive activity. Compound 7c, the most potent member of this series, had an in vitro IC50 of 1.4 X 10(-8) M and showed modest oral antihypertensive activity at 30 mg/kg in conscious
制备了一系列与CI-906,CI-907和依那普利有关的非巯基修饰的二肽,其中各种等位异构部分(O,S,SO,SO2)已取代了氨基,且脯氨酸残基具有被各种疏水性氨基酸取代。在体外评估该化合物对血管紧张素转化酶的抑制作用,在体内评估其抗高血压活性。化合物7c是该系列中最有效的成员,其体外IC50为1.4 X 10(-8)M,并且在有意识的两只肾脏,一只夹子Goldblatt高血压大鼠中以30 mg / kg的剂量显示适度的口服降压活性。讨论了构效关系。
