Herein is reported the synthesis of a tricyclic peptidomimetic scaffold derived from the combination of trans-4-hydroxy-l-proline and tartaric acid derivatives by means of amidation and acid trans-acetalisation reactions. Further manipulations of the hydroxylic function on the pyrrolidine ring gave access to a new set of amino acid scaffolds possessing high rigidity and a fixed arrangement of the functional
药物发现研究已利用拟肽化学技术来获得具有生物活性肽的结构和功能特征以及增强的对蛋白酶的新陈代谢抗性的新线索。本文报道了通过酰胺化和酸反式-缩醛化反应,由反式-4-羟基-1-脯氨酸和酒石酸衍生物的组合衍生的三环拟肽支架的合成。进一步操作吡咯烷环上的羟基官能团可得到一组新的氨基酸支架,这些支架具有高刚性和官能团的固定排列。
