Two classes of 5-substituted benzimidazoles were identified as potent antagonists of the NR2B subtype of the N-methyl-d-aspartate (NMDA) receptor. Selected compounds show very good selectivity versus the NR2A, NR2C, and NR2D subtypes of the NMDA receptor as well as versus hERG-channel activity and alpha(1)-adrenergic binding. Benzimidazole 37a shows excellent activity in the carrageenan-induced mechanical
两类5取代的苯并咪唑被确定为N-甲基-d-天冬氨酸(NMDA)受体NR2B亚型的有效拮抗剂。所选化合物与NMDA受体的NR2A,NR2C和NR2D亚型以及hERG通道活性和α(1)-肾上腺素结合相比显示出非常好的选择性。苯并咪唑37a在大鼠角叉菜胶诱导的机械性痛觉过敏试验中显示出色的活性,并且在狗中显示出良好的药代动力学行为。
