A series of 3-substituted 1-(aminomethyl)-3,4-dihydro-5-hydroxy-1H-2- benzopyrans were prepared as potential D1 selective antagonists. The compounds were evaluated for their affinity and selectivity for the D1 receptor as well as for their functional antagonism of D1-mediated pharmacological events. The compounds show potent D1 antagonist properties in vitro. The optimum nitrogen substitution was found
制备了一系列3-取代的1-(氨基甲基)-3,4-二氢-5-羟基-1H-2-苯并吡喃,作为潜在的D1选择性拮抗剂。评价化合物对D1受体的亲和力和选择性,以及对D1介导的药理作用的功能拮抗作用。这些化合物在体外显示出有效的D1拮抗剂特性。发现最佳的氮取代是伯胺,并且观察到的在6-位取代的效力的顺序是OH大于Br大于H大于OMe。还对体内的两种代表性化合物(6-甲基和6-溴类似物)的多巴胺能活性进行了评估。有趣的是,两种化合物均表现为有效的体内激动剂。
