a non-competitive antagonist. Molecular docking studies in which 6c was docked into the X-ray crystal structure of the GluA2 tetramer suggest that (−)-arctigenin and its analogues bind in the transmembrane domain in a similar manner to the known AMPA receptor non-competitive antagonists GYKI53655 and the antiepileptic drug perampanel. The arctigenin derivatives described herein may serve as novel leads
(−)-Arctigenin 和一系列新类似物已被合成,然后使用 Ca 2+流入测定测试其作为 HEK293 细胞中表达的人同聚 GluA1 和 GluK2 受体的 AMPA 和红藻氨酸受体拮抗剂的潜力。一般来说,这些化合物对两种受体都显示出拮抗剂活性,并且对 AMPAR 的活性明显更高。 Schild 分析表明螺环类似物6c充当非竞争性拮抗剂。分子对接研究表明, 6c对接至 GluA2 四聚体的 X 射线晶体结构中,表明 (−)-牛蒡苷元及其类似物在跨膜结构域中的结合方式与已知的 AMPA 受体非竞争性拮抗剂 GYKI53655 和抗癫痫药吡仑帕奈。本文描述的牛蒡甙元衍生物可以作为开发治疗癫痫的药物的新先导物。
