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
通过杂环取代almorexant的四氢异喹啉核心骨架中的二甲氧基苯基部分,制备了一系列新的非肽类OX 1 R / OX 2 R食欲素受体拮抗剂。引入取代的咪唑基团可提供有效的双orexin受体拮抗剂,对hOX 1 R和hOX 2 R具有纳摩尔浓度,适用于进一步的微调。这些通讯中描述了这些新的orexin受体拮抗剂的制备以及初步的结构-活性关系研究的结果。
