N-4 nitrogen to dopaminergic pharmacophores of the 2-(5-benzimidazole)ethyl-, 2-(5-benztriazole)ethyl-, 2-[5-(benzimidazole-2-thione)]ethyl- and 2-[6-(1,4-dihydroquinoxaline-2,3-dione)]ethyl-type were selected according to known structure-affinity requirements of 1-arylpiperazines. All the new compounds were evaluated for in-vitro binding affinity at the dopamine (D1 and D2) and 5-HT1A receptors. Synaptosomal
为了产生新的混合的D2 / 5HT1A配体,已合成了22种不同的化合物。为此,通过N-4氮与2-(5-苯并咪唑)乙基-,2-(5-苯并三唑)乙基-,2- [5-(苯并咪唑-2-硫酮)的多巴胺能药效团连接的1-取代的苯基哌嗪根据1-芳基哌嗪的已知结构亲和性要求选择)]乙基和2- [6-(1,4-二氢喹喔啉-2,3-二酮)]乙基类型。评价所有新化合物对多巴胺(D1和D2)和5-HT1A受体的体外结合亲和力。由新鲜牛尾状核和海马体制备的突触体膜分别用作多巴胺和5-羟色胺受体的来源。[3H] SCH 23390(D1选择性),将[3H]哌隆(D2选择性)和8-OH- [3H] DPAT(5-HT1A选择性)用作放射性配体。这些化合物均未表达对D1多巴胺受体结合的亲和力。化合物3b和4b在8-OH- [3H] DPAT竞争剂中是无效的,而1b,2b和4b在[3H]哌啶结合测定中是无活性的。测试的其他
