benzisothiazolylpiperazine derivatives combining potent dopamine D2 and D3, and serotonin 5-HT1A and 5-HT2A receptor properties were synthesized and evaluated for their potential antipsychotic properties. The most-promising derivative was 9j. The unique pharmacological features of 9j were a high affinity for D2, D3, 5-HT1A, and 5-HT2A receptors, together with a 20-fold selectivity for the D3 versus D2 subtype, and
合成了一系列结合强力多巴胺D 2和D 3以及5-羟色胺5-HT 1A和5-HT 2A受体特性的新型苯并异噻唑基哌嗪衍生物,并评估了其潜在的抗精神病特性。最有前途的导数是9j。的独特的药理学特征9J是为d的高亲和性2,d 3,5-HT 1A和5-HT 2A受体,与用于d 20倍的选择性一起3与d 2亚型,和对于低亲和力毒蕈碱M 1(降低抗胆碱能副作用的风险)和hERG通道(降低QT间期延长的发生率)。在动物行为模型中,9j抑制了苯环利定的运动刺激作用,阻断了条件回避反应,并改善了大鼠的新型物体识别测试中的认知缺陷。9j表现出较低的僵化潜能,与利培酮的结果一致。另外,在大鼠中检测到了良好的9j脑渗透率。这些研究表明9j是潜在的非典型抗精神病药候选物。
