building blocks based on 5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridine as well as 5,6,7,8-tetrahydro[1,2,4]triazolo[1,5-a]pyridine cores have been prepared. These compounds are non-flat, bicyclic heterocycles that are likely to find utility as privileged motifs for lead-like compound design. One set of building blocks, (5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-6-ylmethyl)amines, proved useful
六组基于5,6,7,8-四氢[1,2,4]三唑[4,3- a ]吡啶以及5,6,7,8-四氢[1,2,已经制备了4]三唑并[1,5- a ]吡啶核。这些化合物是非平面的双环杂环,很可能会用作铅样化合物设计的优先基序。一组结构单元,(5,6,7,8-四氢[1,2,4]三唑并[4,3 - a ]吡啶-6-基甲基)胺被证明可用作开发刺激胰高血糖素的化合物的支架样肽-1(GLP-1)的分泌,是新型抗糖尿病药物的先导。
