  Synthesis and Evaluation of Novel Radioligands for Positron Emission Tomography Imaging of the Orexin-2 Receptor

  摘要：

  Orexin receptors (OXRs) in the brain have been implicated in diverse physiological and neuropsychiatric conditions. Here we describe the design, synthesis, and evaluation of OXR ligands related to (1R,2S)-2-(((2-methyl-4-methoxymethylpyrimidin-5-yl)oxy)methyl)-N-(5-fluoropyri- din-2-yl)-2-(3-fluorophenyl)cyclopropanecarboxamide (9a) applicable to positron emission tomography (PET) imaging. Structural features were incorporated to increase binding affinity for OXRs, to enable carbon-11 radiolabeling and to adjust lipophilicity considered optimal for brain penetration and low nonspecific binding. 9a displayed nanomolar affinity for OXRs, and autoradiography using rat brain sections showed that specific binding of [C-11]9a was distributed primarily to neocortical layer VI and hypothalamus, consistent with reported localizations of orexin-2 receptors (OX(2)Rs). In vivo PET study of [C-11]9a demonstrated moderate uptake of radioactivity into rat and monkey brains under deficiency or blockade of P-glycoprotein, and distribution of PET signals in the brain was in agreement with autoradiographic data. Our approach and findings have provided significant information for development of OX2R PET tracers.

  摘要：

  Orexin / hypocretin受体是G蛋白偶联受体的一个家族，由orexin-1（OX 1）和orexin-2（OX 2）受体亚型组成。食欲素受体在整个中枢神经系统中表达，并参与睡眠/觉醒周期的调节。由于这些受体的调节构成了与睡眠和清醒控制相关的疾病（如失眠）的新型治疗的有希望的靶标，因此，orexin受体拮抗剂的开发已成为药物发现研究中的重要重点。在这里，我们报告了新型orexin受体拮抗剂的设计，合成，表征和结构-活性关系（SAR）。对先前开发的化合物的核心结构进行了各种修改（-）-5（铅分子）产生具有改进的化学和药理学特征的化合物。研究提供了潜在的治疗剂，（1 R，2 S）-2-{[（（2,4-二甲基嘧啶-5-基）氧基]甲基} -2-（3-氟苯基）-N-（5-氟吡啶） -2-基）环丙烷甲酰胺（E2006），一种口服活性，有效的食欲素拮抗剂。通过使用睡眠参数测量，在体内研究中在小鼠中证明了该功效。

  Because modulation of these receptors constitutes a promising target for novel treatments of disorders associated with the control of sleep and wakefulness, such as insomnia, the development of orexin receptor antagonists has emerged as an important focus in drug discovery research. Here, we report the design, synthesis, characterization, and structure–activity relationships (SARs) of novel orexin receptor
