  inhibitors to date suffer from chemical instability stemming from an amine to nitrile intramolecular cyclization. Installation of a cyclopropyl moiety at either the 3,4- or 4,5-position of traditional 2-cyanopyrrolidide proline mimetics led to compounds with potent inhibitory activity against the enzyme. Additionally, cis-4,5-methanoprolinenitriles with beta-branching in the N-terminal amino acid provided enhanced

  合成了一系列含甲氧脯氨酸腈的二肽模拟物，并将其作为N端序列特异性丝氨酸蛋白酶二肽基肽酶IV（DPP-IV）的抑制剂进行了分析。DPP-IV的催化作用是降解胰高血糖素样肽1的主要手段，胰高血糖素样肽1是葡萄糖刺激的胰岛素分泌的关键介质，而DPP-IV的抑制显示出作为治疗2型糖尿病的新机制的临床益处。但是，迄今为止，许多可逆性抑制剂都具有从胺到腈分子内环化的化学不稳定性。在传统的2-氰基吡咯啉脯氨酸模拟物的3,4-或4,5-位上安装环丙基部分会导致产生对该酶具有强抑制活性的化合物。此外，顺式4 N末端氨基酸带有β支链的5-甲基脯氨酸腈提供了增强的化学稳定性和高抑制力。这类抑制剂还显示了在雄性Zucker大鼠口服葡萄糖激发后抑制餐后葡萄糖升高的能力。

  Six angiotensin II antagonists containing cyclohexylglycine (Chg) or cyclopentylglycine (Cpg) in position 5 were synthesized by stepwise elongation in solution, using the pentafluorophenyl ester method. The influence of substitution on the inhibitory properties of the analogues was studied in four different bioassays. [Sar1,Chg5,Lac8]AII proved to be the most potent antagonist with low intrinsic activity
