A model of the conformation of the enzyme-bound inhibitor of human renin suggested the possibility of a gamma-lactam conformational restriction at the P2-P3 site. Synthetic routes to these gamma-lactam dipeptide isosteres and their incorporation into potential renin inhibitors are described. Peptide VIa,b with a gamma-lactam conformational constraint and a hydroxyethylene isostere at the cleavage site
人肾素的酶结合抑制剂的构象模型表明在P2-P3位点存在γ-内酰胺构象限制的可能性。描述了这些γ-内酰胺二肽等排体的合成途径及其掺入潜在的肾素抑制剂中。具有γ-内酰胺构象约束和在裂解位点处的羟乙烯等排物的肽VIa,b抑制人血浆肾素,IC 50值为6.5 nM。这些合成方法的灵活性应为研究酶结合构象异构体提供许多具有这种结构特征的潜在酶抑制剂。
