receptor/Ki for the dopamine D-4 receptor). Increasing in the effective size of the alkyl substituent at the tertiary amine nitrogen atom in the 1,2,3,6-tetrahydro-4-pyridinyl moiety in the 5H-dibenzo[a,d]cycloheptene series reduces the affinity for the dopamine D-4 receptor, but in the dibenz[b,f]oxepin series, no significant change in binding affinity to the dopamine D-4 receptor was observed.

5,11-双-和11-碳-5-氧基-10-(1-烷基-1,2,3,6-四氢-4吡啶基)类似物和11-碳-5-氧基-10-的系列制备非典型抗精神病药氯氮平的(1-甲基-4-哌啶基)类似物,并测试其与多巴胺D-2L和D-4以及5-羟色胺S-2A和S-2C受体的结合。发现其中一些类似物具有多巴胺D-2L和D-4以及5-羟色胺S-2A和S-2C受体的结合活性高达或高于氯氮平,这表明二氮杂结构和哌嗪环均不存在。氯氮平对于高抗多巴胺活性和/或高多巴胺D-4选择性(多巴胺D-2L受体的Ki /多巴胺D-4受体的Ki)必不可少。增加1,2,3中叔胺氮原子处烷基取代基的有效尺寸,5H-二苯并[a,d]环庚烯系列中的6-四氢-4-吡啶基部分降低了对多巴胺D-4受体的亲和力,但在二苯并[b,f] oxepin系列中,与观察到多巴胺D-4受体。观察到两个系列中的10-(1-乙基-1,2,3,6-四氢-4-吡啶基)
