The affinities of tetrahydroprotoberberines for dopamine receptors dramatically decrease after cleaving the central C‐N bond to the analogous ten‐membered dibenzo[c,g]azecines [1]. In the present work, we also synthesized eleven‐membered homologues of these heterocycles and measured the affinities of the resulting dibenzazaundecenes and their underlying homoberberines for human dopamine receptors as
四氢原小檗碱对多巴胺受体的亲和力在切断与类似的十元二苯并 [c, g] 氮杂环庚烷 [1] 的中央 C-N 键后显着降低。在目前的工作中,我们还合成了这些杂环的 11 元同系物,并测量了所得二苯并十一碳烯及其潜在高小檗碱对人多巴胺受体的亲和力以及所有目标化合物对人神经胶质细胞的细胞毒性作用。四环异 C-高小檗碱衍生物显示为 D4 选择性拮抗剂,而所有其他活性化合物显示出显着的 D1/D5 选择性。为了解释我们的发现,测量了能量最小化构象的距离。
