A new class of mu selective receptor antagonists has been developed using a combinatorial approach based on previously reported Dmt-Tic dipeptide ligands. Modified tetrahydroisoquinoline (Tiq) residues were reacted with different electrophiles in order to create novel molecules that would mimic the original dipeptide. A specific class of thioureas bearing basic pyrrolidine residues were shown to give
基于先前报道的Dmt-Tic二肽配体,使用组合方法已经开发出一类新型的mu选择性受体拮抗剂。修饰过的四氢异喹啉(Tiq)残基与不同的亲电子试剂反应,以产生可模仿原始二肽的新型分子。带有碱性吡咯烷残基的一类特定的硫脲显示出良好的结合亲和力。吡咯烷环与苄基衍生物的进一步烷基化也证明增加了mu结合亲和力。另外,证明了通过具有氢键特性(供体/受体)的苄基环周围的极性基团的存在增强了mu结合。这类新的配体代表了阿片类似物开发中的新型支架。
