A series of new 1,4-disubstituted triazoles was prepared from appropriate arylacetylenes and aminoalkylazides using click chemistry methodology. These compounds were evaluated as potential ligands on several subtypes of dopamine receptors in in vitro competition assays, showing high affinity for dopamine D3 receptors, lower affinity for D2 and D4, and no affinity for the D1 receptors. Compound 18 displayed
使用点击化学方法,由合适的芳基乙炔和氨基烷基叠氮化物制备了一系列新的1,4-二取代的三唑。在体外竞争试验中,这些化合物被评估为几种多巴胺受体亚型上的潜在配体,显示出对多巴胺D 3受体的高亲和力,对D 2和D 4的低亲和力以及对D 1受体的不亲和力。化合物18在D 3受体上显示出最高亲和力,K i值为2.7 nM,相对于D 2(70倍)和D 4(200倍)具有选择性,并在低纳摩尔范围内表现为竞争性拮抗剂。
