10-(4-Methylpiperazino)dibenz[b,f]oxepins were prepared and evaluated as potential antipsychotic agents using specific clozapine [8-chloro-11-(4-methylpiperazino)-5H-dibenzo[b,e][1,4]diazepine] binding sites in rat forebrain that are noncholinergic and nondopaminergic in nature and from which [3H]clozapine is displaced by known antipsychotic agents. [3H]Clozapine binding in the presence of atropine
使用特定的氯氮平[8-氯-11-(4-甲基哌嗪子基)-5H-二苯并[b,e] [1,4]制备了10-(4-甲基哌嗪子基)二苯并[b,f]恶心素并评估为潜在的抗精神病药。大鼠前脑中的[diazepine]结合位点,本质上是非胆碱能和非多巴胺能的,[3H] clozapine可通过已知的抗精神病药从中取代。[3H]在阿托品存在下的氯氮平结合代表非毒蕈碱结合,而在没有阿托品存在下的结合代表毒蕈碱(胆碱能)加非毒蕈碱结合。对多巴胺结合位点的相对亲和力是通过从大鼠尾状核中的结合位点置换[3H]螺哌啶醇来确定的。因此,氯氮平,其2-氯异构体,其脱氯类似物及其5H-二苯并[a,d]环庚烯和二苯并[b,氟哌啶类似物对非毒蕈碱型氯氮平结合位点具有大约相同的相对亲和力。在螺哌啶醇(多巴胺能)位点上,三环系统的性质和三环系统上氯原子的存在对结合亲和力都有实质性影响。在每个系列中,将氯原子从哌嗪子基团的远端位置移
