In the course of the identification of new indole derivatives targeting GluN2B-subunit-containing N-methyl-d-aspartate (NMDA) receptor, the (N-1H-indol-6-methanesulfonamide-3-yl)-2-(4-benzylpiperidin-1-yl)ethanone (10b) was identified as a potent ligand for this NMDA receptor subunit. It displays very high binding affinity (IC50 of 8.9 nmol) for displacement of [3H]ifenprodil, thus showing improved
在新的吲哚衍生物的标识的过程中靶向含GluN2B亚基- Ñ甲基d天冬氨酸(NMDA)受体,所述(Ñ -1 ħ吲哚-6-甲磺酰胺-3-基)-2-(4- -苄基哌啶-1-基)乙酮(10b)被确定为该NMDA受体亚基的有效配体。它显示出对[ 3 H] ifenprodil置换的非常高的结合亲和力(IC 50为8.9 nmol),因此,相对于先前报道的类似物,通过功能测定证实,其效能更高。这一发现与化合物10b的对接姿势一致 在定位于NMDA受体四异聚复合物的GluN1-GluN2B亚基界面的结合口袋中。
