to 100 microM. D2 competition binding showed the 1-benzyl derivative to possess the highest affinity, followed by 4-phenyl greater than SCH23390 greater than 1-phenyl. The tertiary 1-phenyl derivative was more potent than the secondary 1-phenyl analogue in all assays. Interestingly, resolution and single-crystal X-ray analysis of the tertiary N-methyl-1-phenyltetrahydroisoquinoline showed the most active
已经制备了一系列的1-苯基-,4-苯基-和1-苄基-1,2,3,4-四氢异喹啉作为原型D1多巴胺受体拮抗剂SCH23390 [[R-(+ )-7-氯-8-羟基-3-甲基-1-苯基-2,3,4,5-四氢-1H- 3-苯并ze庚因]。这些异喹啉对D1受体的亲和力和选择性由大鼠纹状体制备的膜匀浆中的三个生化终点确定:完成[3H] SCH23390结合位点的能力;竞争[3H] spiperone(D2受体配体)结合位点的能力;对多巴胺刺激的腺苷酸环化酶的影响 在D1位点的竞争性结合测量表明SCH23390具有最高的亲和力,其后是异喹啉的1-苯基大于1-苄基,大于4-苯基。这些结果与测试化合物拮抗多巴胺刺激的腺苷酸环化酶的能力高度相关(r = 0.98)。单独的化合物均未在10 nM至100 microM的浓度下刺激cAMP的形成。D2竞争结合表明1-苄基衍生物具有最高的亲和力,其次是4-苯基大于S
