  一系列新型 GluN2C 选择性增强剂的设计、合成和结构-活性关系

  摘要：

  NMDA受体是介导慢速的Ca GluN1和GluN2A-d亚基组成的四聚体复合2+ -兴奋性突触传递的渗透组分。NMDA 受体与广泛的神经系统疾病有关，因此代表了一个重要的治疗靶点。我们在此描述了一系列新型吡咯烷酮，它们选择性地仅增强含有 GluN2C 亚基的 NMDA 受体。测试的最活跃的类似物对重组 GluN2C 受体的选择性是对 GluN2A/B/D 含 NMDA 受体以及 AMPA 和红藻氨酸受体的 100 倍以上。该系列代表了第一类对含二异聚体 GluN2C 的 NMDA 受体具有选择性的变构增效剂。
