A series of new 1-aryl-6,7-dihydroxy tetrahydroisoquinolines with several substitution patterns in the 1-aryl group at C-1 were prepared in good yields. The influence of each substituent on the affinity and selectivity for D1 and D2 dopaminergic receptors was studied. Moreover, N-alkyl salts of these tetrahydroisoquinolines were used as starting material to synthesize a series of new 1-aryl-7,8-dihydroxy
以高收率制备了一系列新的1-芳基-6,7-二羟基四氢异喹啉,它们在C-1的1-芳基上具有多个取代模式。研究了每个取代基对D 1和D 2多巴胺能受体的亲和力和选择性的影响。而且,N这些四氢异喹啉的β-烷基盐被用作原料,通过非对映选择性的Stevens重排合成一系列在C-2位具有吸电子取代基的新的1-芳基-7,8-二羟基3-四氢苯并ze庚因衍生物。探索了这些化合物的结构-活性关系,以评估苯并pine庚因在C-2处的官能团的作用以及异喹啉C-1位置处芳基的修饰对上述受体的亲和力和选择性。1-芳基-6,7-二羟基四氢异喹啉4c对D 2受体具有显着的亲和力,与K i值为31 nM。这种显着的亲和力可以归因于硫代甲基的存在,并且它是迄今为止报道的最具活性的1-芳基-6,7-二羟基四氢异喹啉衍生物。
