The experimental details for the synthesis of human renin inhibitors are described. In order to aviod metabolic degradation of the Phe-His (P3-P2) amide bond in transition-state analogs, structurally modified acyl residues (P4-P3) were incorporated into the inhibitors. Compound 1a, which contained 2-(1-naphthylmethyl)-3-(N-phenethylcarbamoyl)propionyl residue (P4-P3) with a retro-inverso amide bond, L-histidine, and norstatine isoamylamide residue (P1-P1') as a transition-state mimic, had potent human renin inhibitory activity, and it lowered blood pressure when administered orally to common marmosets.
人肾素抑制剂的合成实验细节如下所述。为了防止过渡态类似物中Phe-His (P3-P2)酰胺键的代谢降解,抑制剂中融入了结构改良的酰基残基 (P4-P3)。化合物1a包含2-(1-萘甲基)-3-(N-苯乙基氨基甲酰)丙酰基残基 (P4-P3),具有逆向内酰胺键,L-组氨酸和诺丝他汀异戊酰胺残基 (P1-P1') 作为过渡态模拟结构,显示出强大的人肾素抑制活性,并通过口服给药降低了普通狨猴的血压。
