The metabotropic glutamate receptor 4 (mGluR4) is an emerging target for the treatment of Parkinson’s disease (PD). However, since the discovery of its therapeutic potential, no ligand has been successfully developed enough to be tested in the clinic. In the present paper, we report for the first time the medicinal chemistry efforts conducted around the pharmacological tool (−)-PHCCC. This work led
代谢型谷氨酸受体4(mGluR4)是治疗帕金森氏病(PD)的新兴靶标。然而,自发现其治疗潜力以来,没有成功开发出足以在临床上进行测试的配体。在本文中,我们首次报告了围绕药理学工具(-)-PHCCC进行的药物化学研究。这项工作导致了化合物40的鉴定,一种有效的,选择性的mGluR4阳性变构调节剂(PAM),具有良好的水溶性,并在腹膜内给药后在经过验证的PD运动症状的临床前啮齿动物模型中表现出一致的活性:氟哌啶醇在小鼠和大鼠中引起的僵直和6-羟基多巴胺(6-OHDA)病变模型。此外,我们还描述了口服给药后化合物60与化合物40的紧密类似物具有改善的药代动力学特征的鉴定。基于其有利和独特的临床前特性,化合物60(PXT002331,现为foliglurax)被提名为临床开发的候选药物。
