nociceptin and NOP receptor, our research effort sought to identify orally available NOP antagonists. Our effort led to the discovery of a novel chemical series based on the dihydrospiro(piperidine-4,7′-thieno[2,3-c]pyran) scaffold. Herein we show that dihydrospiro(piperidine-4,7′-thieno[2,3-c]pyran)-derived compounds are potent NOP antagonists with high selectivity versus classical opioid receptors (μ, δ
Nociceptin / OFQ(N / OFQ)是17个氨基酸的肽,是ORL1 / NOP受体的内源性配体。除喂食行为外,伤害感受素似乎还调节许多生理功能,例如对压力,焦虑,情绪和药物滥用的生物反应。为了开发研究伤害感受素和NOP受体功能的工具,我们的研究工作试图确定口服可用的NOP拮抗剂。我们的努力导致发现了一种基于二氢螺环(哌啶-4,7'-thieno [2,3- c ] pyran )支架的新型化学系列。在这里,我们显示了二氢螺(哌啶-4,7'-thieno [2,3- c源自[] pyran)的化合物是有效的NOP拮抗剂,相对于传统的阿片受体(μ,δ和κ)具有高选择性。此外,在大鼠口服给药后,这些化合物表现出足够的生物利用度以在脑中产生高水平的NOP受体占有率。
