  BI-9508 的发现，一种用于小鼠体内研究的脑渗透性 GPR88 受体激动剂工具化合物

  摘要：

  G 蛋白偶联受体 GPR88 的活性和表达降低与许多行为相关的神经系统疾病有关。已发表的临床前 GPR88 变构激动剂均具有阻碍其进入临床的体内药代动力学特性，包括高亲脂性和较差的脑渗透性。在这里，我们描述了我们改进 GPR88 激动剂的药物样特性的尝试，以及我们对成功靶向 GPR88 变构袋所需的权衡的分析。我们发现了两种新的 GPR88 激动剂：一种在小鼠概念验证研究中可减少吗啡诱导的运动活动，另一种是阻转异构体 BI-9508，它是一种脑渗透剂，具有改善的药代动力学特性和剂量，推荐在未来的研究中使用。啮齿类动物的体内研究。 BI-9508仍然存在高亲脂性，该系列的研究已停止。由于其作为工具化合物的实用性，我们现在通过勃林格殷格翰的开放创新门户 opnMe.com 为研究人员免费提供 BI-9508 和阴性对照。

  Considering their growing attention in the field of medicinal chemistry and drug-discovery research, the facile and convenient approaches towards the preparation of 2-aryl benzoxazole derivatives have been described. The transformation is accomplished by using Fe(III)-catalyzed C–H activation of benzoxazoles with boronic acids to obtain a wide range of C2-arylated benzoxazoles in high yields. The developed

  考虑到他们在药物化学和药物发现研究领域日益受到关注，已经描述了制备 2-芳基苯并恶唑衍生物的简便方法。该转化是通过使用 Fe(III) 催化的苯并恶唑与硼酸的 C-H 活化来实现的，从而以高产率获得范围广泛的 C2-芳基化苯并恶唑。开发的方法排除了作为副产物的自偶联化合物的形成。另一方面，产物的合成也是通过无金属多米诺协议通过 1-亚硝基-2-萘酚和苯乙酮在 Cs2CO3 作为碱存在下使用催化量的 CBr4 进行反应来实现的。设计的串联方法避免使用预活化的 α-卤代酮作为底物。
