Analogues of the renin octapeptide substrate were synthesized in which replacement of the scissile dipeptide with (3S,4S)-4-amino-3-hydroxy-6-methylheptanoic acid (statine, Sta) transformed the substrate sequence into potent, transition-state analogue, competitive inhibitors of renin. Synthesis and incorporation of the cyclohexylalanyl analogue of Sta, (3S,4S)-4-amino-5-cyclohexyl-3-hydroxypentanoic
合成了肾素八肽底物的类似物,其中用(3S,4S)-4-氨基-3-羟基-6-甲基庚酸(statine,Sta)取代易裂二肽将底物序列转变为有效的过渡态类似物,肾素的竞争性抑制剂。Sta的环己基丙氨酰基类似物(3S,4S)-4-氨基-5-环己基-3-羟基戊酸(ACHPA)的合成和掺入提供了迄今为止报道的最有效的肾素抑制剂,包括N-异戊基-L-组氨酸-L-脯氨酰基-L-苯丙氨酰基-L-组氨酸-ACHPA-L-亮氨酰-L-苯丙氨酰胺[Iva-His-Pro-Phe-His-ACHPA-Leu-Phe-NH2,3],肾素抑制Ki = 1.6 X 10(-10)M(人肾素),IC50 = 1.7 X 10(-10)M(人血浆肾素),IC50 = 1.9 X 10(-9)M(犬血浆肾素)和IC50 = 2.1 X 10(-8)M(大鼠血浆肾素)。含有ACHPA的这种抑制剂3,与人肾素的效价比含Sta的抑
