behaves as a silent antagonist at rD2 receptors while activating h5-HT1A receptors with an efficacy at least equivalent to that of the prototypical 5-HT1A agonist (+/-)-8-OH-DPAT. These dual actions confer a unique pharmacological profile to the product. In a behavioral model predictive of positive symptoms, 16 has an activity comparable to that of the typical antipsychotic haloperidol, while it is devoid
我们报告发现和合成的新型,潜在的抗精神病药化合物在同一分子中结合有效的多巴胺D2受体拮抗剂和5-羟色胺5-HT1A受体激动剂的性质。我们描述了导致我们有希望的衍生物的结构-活性关系:N-[(2,2-二甲基-2,3-二氢-苯并呋喃-7-酰氧基)乙基] -3-(环戊-1-烯基)-苯甲酰胺16。后者对D2和5-HT1A受体具有高亲和力,而对5-HT2A位点仅具有较弱的亲和力。在信号转导的细胞模型中,16充当rD2受体的沉默拮抗剂,同时激活h5-HT1A受体,其功效至少相当于典型的5-HT1A激动剂(+/-)-8-OH-DPAT。这些双重作用赋予产品独特的药理作用。在可预测阳性症状的行为模型中,16的活性与典型的抗精神病药氟哌啶醇相当,而没有致晕作用。尽管它会在大鼠中产生5-HT1A受体激活的行为特征,但它们的剂量比(+/-)-8-OH-DPAT的剂量高100倍。我们认为16种D2和5-HT1A作
