assessed by studies of the related amino analogues 23 and 24 and hydroxy analogue 27. The 3-bromo compound 11 (FLB 463) was studied in various in vivo models and compared with the dopamine-D2 antagonists sulpiride, raclopride, eticlopride, and haloperidol. The high potency of 11 to selectively block dopamine-D2 receptors in vitro and in vivo combined with indications on a low potential for motor side effects
由相应的2,5,6-三甲氧基苯甲酸合成了一系列3-取代的5,6-二甲氧基水杨酰胺III(9-13和15)。III中甲氧基的弛豫时间T1和碳的化学位移表明,6-甲氧基相对于溶液中的环平面呈几乎垂直的取向,而5-甲氧基相对于环平面呈更共面的取向。在体外,水杨酰胺III对[3H]哌酮和[3H] raclopride结合位点显示出很高的立体选择性亲和力。区域异构的水杨酰胺IV对[3H] spiperone结合位点也显示出明显但低于III的亲和力。通过研究相关的氨基类似物23和24和羟基类似物27进一步评估了结构要求。在各种体内模型中研究了3-溴化合物11(FLB 463),并将其与多巴胺D2拮抗剂舒必利,雷洛必利,依替普利和氟哌啶醇进行了比较。11在体外和体内选择性阻断多巴胺D2受体的高效力以及对运动副作用的潜在可能性较低的迹象使其成为取代水杨酰胺类中非常有趣的新成员。
