D3 DA receptors, as exemplified by compounds 11-15 and 21-26, while some had a reasonable selectivity for the DA D3 receptors. The affinities of the 2-aminotetralins for the D21, receptor depended on the type of radioligand (agonist or antagonist) used. The agonist affinity data, obtained by using the agonist ligand [3H]N-0437, are thought to be more relevant for calculating DA receptor subtype selectivity
制备了一系列2-氨基四氢化萘,在5-或7位上被甲氧基或羟基取代,并具有不同的N-烷基或N-芳基烷基取代基,并在人多巴胺(DA)D2的结合测定中进行了评估,D3和D4受体。该系列的某些成员是在以前的研究中准备的,但从未在体外用单受体亚型进行测试,因此再次进行了检查。所测试的2-氨基四氢化萘均未显示出对多巴胺D4受体的高亲和力。但是,如化合物11-15和21-26所示,许多2-氨基四氢萘林对D2和D3 DA受体均显示出高亲和力,而有些对DA D3受体具有合理的选择性。2-氨基四氢萘林对D21受体的亲和力取决于所用放射性配体(激动剂或拮抗剂)的类型。激动剂亲和力数据,
