A series of four non-peptidic renin inhibitors have been designed and synthesized. All of them contain in their molecule (3S,4S)-4-amino-5-cyclohexyl-3-hydroxypentanoic acid (ACHPA), a hydrophobic portion at the C-terminus and a second dipeptide-like transition state analog or unnatural dipeptidic fragment at the N-terminus. Inhibitory activity of the compounds was measured in vitro by high performance liquid chromatography (HPLC). Their IC50 (M/l) values were: <10−3 (12), 1.0×10−6 (19), 4.0×10−4 (23) and 1.0×10−6 (29), respectively. All the compounds are stable against chymotrypsin.
我们设计并合成了一系列四种非肽类肾素抑制剂。它们的分子中都含有(3S,4S)-4-氨基-5-环己基-3-羟基戊酸(ACHPA),C-端为疏水部分,N-端为第二个二肽样过渡态类似物或非天然二肽片段。这些化合物的抑制活性是通过高效液相色谱法(HPLC)在体外测定的。它们的 IC50(<小>M小>/升)值分别为分别为 <10-3 (12)、1.0×10-6 (19)、4.0×10-4 (23) 和 1.0×10-6 (29)。所有化合物对糜蛋白酶都很稳定。
