A novel series of non-peptidic OX1R/OX2R orexin receptor antagonists was prepared by heterocyclic replacement of the dimethoxyphenyl moiety contained in the tetrahydroisoquinoline core skeleton of almorexant. Introduction of substituted imidazole moieties delivered potent dual orexin receptor antagonists with nanomolar potency for hOX1R and hOX2R suitable for further fine-tuning. The preparation of

skeleton of almorexant by appropriately substituted imidazoles afforded novel 1-chloro-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazinederivatives as potent dual orexin receptor antagonists. We describe in this Letter our efforts to further optimize the potency and brain penetration of these derivatives by fine-tuning of the pivotal phenethyl motif, and we comment on the sleep-promoting activity of selected compounds
用适当取代的咪唑代替almorexant核心骨架中的二甲氧基苯基部分,可提供新的1-氯-5,6,7,8-四氢咪唑并[1,5- a ]吡嗪衍生物,作为有效的双orexin受体拮抗剂。我们在这封信中描述了我们通过微调枢轴苯乙基基序进一步优化这些衍生物的功效和大脑渗透的努力,并评论了大鼠脑电图(EEG)模型中所选化合物的睡眠促进活性。
