report the design and synthesis of new conformationally restricted 2-aminoadipic acid (2AA) –, and glutamic acid , analogs, which share the cyclopropane ring as the restrictor. The analogs were characterized at rat mGlu1−8 in an IP-One functional assay. While the 2AA analogs , and CCG-I analog were shown to be selective mGlu2 agonists with low micromolar potencies, CCG-II analog was shown to be a potent
代谢型谷氨酸 (Glu) 受体 (mGluR) 是 G 蛋白偶联受体,在调节中枢神经系统 (CNS) 的兴奋性神经传递中发挥核心作用。因此,其工具化合物的开发继续引起科学界的兴趣。在这项研究中,我们报告了新型构象限制性 2-氨基己二酸 (2AA) 和谷氨酸类似物的设计和合成,它们共享环丙烷环作为限制器。在 IP-One 功能测定中对大鼠 mGlu1−8 的类似物进行了表征。虽然 2AA 类似物和 CCG-I 类似物被证明是具有低微摩尔效力的选择性 mGlu2 激动剂,但 CCG-II 类似物被证明是 mGlu2 的有效完全激动剂 (EC = 82 nM),选择性比 mGlu3 高约 15 倍,比 III 组亚型选择性高 25 倍,比 I 组亚型选择性高 60 倍。进行了一项计算机研究,以解决引入该甲基后效价的显着变化(> 3500 倍)(L-CCG-II 与 )。
