(S)-CPW 399是一种强效的和选择性的AMPA受体激动剂,Ki值为747 nM [1].
α-氨基-3-羟基-5-甲基-4-异恶唑丙酸受体(AMPA受体)是谷氨酸的离子型跨膜受体,在中枢神经系统中介导快速突触传递.AMPA受体由四个蛋白亚基低聚组装而成,即GluR1-4.
(S)-CPW 399是一种强效的和选择性的AMPA受体激动剂.(S)-CPW 399对GluR1\GluR2\GluR3及GluR4受体的亲和力的Ki值分别为109\218\2137及1756 nM[1].在小鼠小脑颗粒细胞中,(S)-CPW 399浓度和时间依赖性地诱发神经细胞死亡,EC50值为70 μM,且浓度依赖性地增加细胞内游离钙水平([Ca2+]i),EC50值为5 μM [2].在大鼠小脑颗粒细胞中,CPW-399增强GABAA受体δ亚基的表达,而其依赖于NMDA受体活化[3].在表达iGluR5的Sf9细胞中,(S)-CPW 399对iGluR5有亲和力,Ki值为44 nM.在非洲爪蟾卵母细胞中,(S)-CPW 399具有激动活性,对iGluR1\iGluR2\iGluR3及iGluR4受体的EC50值分别为24.9, 13.9, 224 and 34.3 μM[4].
