(+)-isomeric counterpart. Binding results indicated highest selectivity for D3 receptors in compound (-)- 10 ( K i = 0.35 nM; D2/D3 = 71). In the 5-hydroxy series, highest selectivity for D3 receptors was exhibited by compound (-)- 25 ( K i = 0.82 nM; D2/D3 = 31.5). Most potent compounds exhibited binding and functional affinities at the sub-nanomolar level for the D3 receptor. Binding assays were carried
本文介绍了一种针对多巴胺D2 / D3受体的氨基四氢萘-哌嗪类杂合分子的扩展结构-活性关系研究。已经开发出各种类似的作为位置异构体的类似物,其中酚羟基在芳族环上的位置已经改变。在两个邻苯二酚衍生物之间,具有两个亚甲基接头长度的化合物6e相对于具有四个亚甲基接头的化合物6f对D3的表现出更高的亲和力和对D3的选择性(6e和6f分别为D2 / D3 = 50.6 vs 7.51)。通常,(-)-异构体比(+)-异构体更有效。结合结果表明对化合物(-)-10中的D3受体具有最高选择性(K i = 0.35 nM; D2 / D3 = 71)。在5-羟基系列中,化合物(-)-25(K i = 0.)对D3受体的选择性最高。82 nM;D2 / D3 = 31.5)。大多数有效的化合物在亚纳摩尔水平上对D3受体表现出结合和功能亲和力。用tri化的烯酮作为放射性配体,用表达D2或D3受体的HEK-
