3,4-tetrahydroisoquinoline derivatives was evaluated for affinity to the PCP binding site of the NMDA receptor complex. The (S)-configured tetrahydroisoquinoline derivative (S)-4 e x HCl bearing a 2-methylphenyl substituent in position 1 of the heterocyclic ring system and a methyl group in position 8 was found to exhibit the highest affinity among the derivatives with a K(i)-value of 0.0374 microM
评价了一系列的1-芳基-1,2,3,4-四氢异喹啉和8-甲基-1-芳基-1,2,3,4-四氢异喹啉衍生物对NMDA受体复合物的PCP结合位点的亲和力。发现在HCl中具有(S)-构型的四氢异喹啉衍生物(S)-4,其在杂环系统的1位带有2-甲基苯基取代基,在8位带有甲基,在具有K( i)值为0.0374 microM。另外,该化合物显示出显着的结合对映选择性,其效力是相应的(R)-对映异构体(R)-4在HCl中的效力几乎高90倍。另外,描述了一种方便有效的外消旋1-芳基-1,2,3,4-四氢异喹啉衍生物的合成方法。
