(4-Benzylpiperidine-1-yl)-(6-hydroxy-1H-indole-2-yl)-methanone (6a) derived from (E)-1-(4-benzylpiperidin-1-yl)-3-(4-hydroxy-phenyl)-propenone (5) was identified as a potent NR2B subunit-selective antagonist of the NMDA receptor. To establish the structure-activity relationship (SAR) and to attempt the improvement of the ADME properties of the lead, a series of compounds were prepared and tested. Several derivatives showed low nanomolar activity both in the binding and in the functional assay. In a formalin-induced hyperalgesia model in mice, 6a and (4-benzylpiperidine-1-yl)-[5(6)-hydroxy-1H-benzimidazol-2-yl]-methanone (60a) were as active as besonprodil (2) after oral administration. A CoMSIA model was developed based on binding data of a series of indole- and benzimidazole-2-carboxamides.
(4-苄基哌啶-1-基)-(6-羟基-1H-吲哚-2-基)-甲酮(6a)是从(E)-1-(4-苄基哌啶-1-基)-3-(4-羟基苯基)丙烯酮(5)中鉴定出的一种强效的NMDA受体NR2B亚基选择性拮抗剂。为了建立结构-活性关系(SAR)并尝试改善先导化合物的ADME性质,制备并测试了一系列化合物。多种衍生物在结合和功能性测定中均显示出低纳摩尔的活性。在环磷酰胺诱导的小鼠痛觉过敏模型中,6a和(4-苄基哌啶-1-基)-[5(6)-羟基-1H-联吡啶-2-基]-甲酮(60a)在口服给药后与Besonprodil(2)具有相同的活性。基于一系列吲哚-和联吡啶-2-羧酰胺的结合数据,开发了一种CoMSIA模型。
