Pepstatin analogues corresponding to the general formula A-X-Y-Sta-Ala-Sta-R were synthesized in solution phase. Various changes in the nature of the A, X, and Y groups were made to improve the inhibitory potency against human plasma renin activity. The results were interpreted by use of the active-site model based on the sequence of human angiotensinogen. The tert-butyloxycarbonyl group and the isovaleryl
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。
