potencies and agonist efficacies among the NMDA receptor subtypes (GluN1/2A–D) in a manner dependent on the GluN2 subunit. Notably, compound 8p is identified as a potent partial agonist at GluN1/2C (EC50 = 0.074 μM) with an agonist efficacy of 28% relative to activation by Gly and virtually no agonist activity at GluN1/2A, GluN1/2B, and GluN1/2D. Thus, these novel agonists can modulate the activity of specific
NMDA 受体介导谷氨酸能神经传递,并且由于它们参与多种精神和神经疾病而成为治疗靶点。在这里,我们描述了一系列 ( R )-3-(5-furanyl)carboxamido-2-aminopropanoic acid analogues 8a – s作为 GluN1 亚基甘氨酸 (Gly) 结合位点激动剂的设计和合成,但不是NMDA 受体的 GluN3 亚基。这些新型类似物以依赖于 GluN2 亚基的方式在 NMDA 受体亚型 (GluN1/2A–D) 中显示出高度可变的效力和激动剂功效。值得注意的是,化合物8p被鉴定为 GluN1/2C (EC 50= 0.074 μM),相对于 Gly 激活的激动剂功效为 28%,并且在 GluN1/2A、GluN1/2B 和 GluN1/2D 上几乎没有激动剂活性。因此,这些新型激动剂可以通过替代完全内源性激动剂 Gly 或d-丝氨酸 ( d -Ser)来调节特定
