A series of 1-propyl-4-arylpiperidines were synthesized and their effects on the dopaminergic and serotonergic systems tested in vivo and in vitro. Scaffold jumping among five- and six-membered bicyclic aryl rings attached to the piperidine ring had a marked impact on these effects. Potent and selective dopamine D2 receptor antagonists were generated from 3-indoles, 3-benzoisoxazoles, 3-benzimidazol-2-one
合成了一系列的1-丙基-4-芳基哌啶,并在体内和体外测试了它们对多巴胺能和5-羟色胺能系统的影响。在连接至哌啶环的五元和六元双环芳基环之间的支架跳跃对这些作用有显着影响。由3-吲哚,3-苯并异恶唑,3-苯并咪唑-2-酮和3-苯并噻吩生成有效的和选择性的多巴胺D 2受体拮抗剂。相反,3-苯并呋喃是单胺氧化酶(MAO)A的有效和选择性抑制剂。合成的化合物对3,4-二羟基苯基乙酸(DOPAC)水平的影响与其对多巴胺D 2的亲和力密切相关在4-芳基哌啶系列中,最有发展前景的化合物是6-氯-3-(1-丙基-4-哌啶基)-1 H-苯并咪唑-2-酮(19),在体内具有典型的多巴胺D 2受体拮抗剂特性,但仅部分降低了自发运动能力。这表明该化合物在患者中诱发帕金森氏症的倾向可能较低。
