在溶液相中合成对应于通式AXY-Sta-Ala-Sta-R的胃抑素类似物。进行了A,X和Y基团性质的各种变化以提高对人血浆肾素活性的抑制能力。通过使用基于人类血管紧张素原序列的活性位点模型来解释结果。发现叔丁氧羰基和异戊酰基是最有效的酰基(A)。在Y位置具有Phe残基代替Val1(X)和His或具有脂肪族侧链的氨基酸(如正亮氨酸或正缬氨酸)的类似物显示出对人血浆肾素活性的最高抑制作用,IC50值约为10(-8) M. C-末端他汀类化合物的羧基的酯化或酰胺化不会改变抑制能力。

The synthesis of five amino phosphorus derivatives, 1a-e, is described. The derivatives were incorporated into a series (18) of analogues of the 5-14 portion of angiotensinogen, in most cases at the scissile Leu-Val bond. The resultant compounds were tested in vitro for their ability to inhibit human plasma renin. Replacement of the scissile bond with the phosphinic analogue of Leu10-Val11 (1b) gave the most potent inhibitors, having IC50 = 7.5 x 10(-8) M for H-Pro-His-Pro-Phe-His-(1b)-Ile-His-Lys-OH and IC50 = 1.0 x 10(-7) M for Z-Arg-Arg-Pro-Phe-His-(1b)-Ile-His-NH2. The shorter phosphonic acid sequence Z-Pro-Phe-His-(1d) retained biological activity with an IC50 = 6.4 x 10(-6) M.
