disorders of the central nervous system (CNS). Still, compounds that are potent mGlu1/5 NAMs with selectivity versus the other six members of the mGlu family as well as the balance of properties required for use in vivo are lacking. A medicinal chemistry effort centered on the identification of a lead series with the potential of delivering such compounds is described in this Letter. Specifically, a new
第一组I型代谢型谷氨酸受体(mGlu 1和mGlu 5)的选择性负变构调节剂(NAM)在文献中已得到很好的表征,并有望在中枢神经系统(CNS)的多种疾病中作为治疗剂。仍然缺乏有效的mGlu 1/5 NAM相对于mGlu家族中其他六个成员具有选择性的化合物,以及体内使用所需性能的平衡。在该信函中描述了以鉴定潜在的铅系列为中心的药物化学工作。具体而言,一类新的吡啶并[1',2':1,5]吡唑并[4,3- d] pyrimidin-4-amines被设计为4-氨基喹唑啉的新型等规替代物,该化学型中的化合物在第I组mGlus上均显示出双重NAM活性。一种化合物VU0467558(29)在两种受体上均表现出近乎均等的活性,与其他mGlus相比具有选择性,具有良好的辅助药理作用,并且在啮齿动物中接触CNS。
