Several alkylpiperazines, monocyclic subfragments of known tricyclic neuroleptic agents, were evaluated as dopamine antagonists in the isolated rabbit ear artery preparation. Compound prepared and evaluated are of the general structure Ar-X-(CH2)n-Y, where X = C, O, and N, n = 1-3, and Y, for the most part, was 4-methylpiperazine. Those compounds where X - NH, n = 3, and X = (Z)-CH - CH, n = 2, with
在分离的兔耳动脉制剂中,几种烷基哌嗪(已知的三环抗精神病药的单环亚片段)被评估为多巴胺拮抗剂。制备和评估的化合物具有一般结构Ar-X-(CH2)nY,其中X = C,O和N,n = 1-3,Y大部分是4-甲基哌嗪。X-NH,n = 3,X =(Z)-CH-CH,n = 2,侧链上有一个吸电子基团的那些化合物,其多巴胺拮抗剂活性与氯氮平相当。结论是,在本研究中使用的受体制剂中,作为多巴胺拮抗剂的最佳活性,吩噻嗪样药物的整个三环结构(或至少大于一个单环系统)是必需的。
