N-Methyl-D-aspartate (NMDA) receptors are heterotetrameric ion channels that can be comprised of different subunits. GluN2A subunit-containing NMDA receptors are associated with diseases like anxiety, depression, and schizophrenia. However, the exact contribution of these NMDA receptor subtypes is still unclear. To understand better the role of the GluN2A-containing receptors, novel ligands were designed
谷氨酸能的N-甲基-D-天冬氨酸(NMDA)受体是异四聚体离子通道,可以包含不同的亚基。含有GluN2A亚基的NMDA受体与焦虑症,抑郁症和精神分裂症等疾病相关。但是,这些NMDA受体亚型的确切作用仍不清楚。为了更好地理解含GluN2A受体的作用,设计了新型配体。与分离的结合位点TCN-201(1)和类似物采用环A和环B平行取向的U形构象。为了增加这些环之间的π/π相互作用,TCN-201的环B被不同的电子富集的噻唑,恶唑,和异恶唑杂环。通过用表达含GluN2A的NMDA受体的非洲爪蟾卵母细胞的两电极电压钳实验测量抑制活性。发现21c,31a,37a和37b能够抑制离子通道。异恶唑衍生物37b是最有效的负变构调节剂,在10μM的浓度下显示40%的TCN-201活性。
