Thirty compounds related to the selective dopamine-autoreceptor agonist 3-(3-hydroxyphenyl)-N-n-propylpiperidine have been synthesized and tested for central dopamine-autoreceptor stimulating activity. The 3-(3-hydroxyphenyl)piperidine moiety seems indispensable for high potency and selectivity. Introduction of an additional hydroxyl group into the 4 position of the aromatic ring gives a compound with
已经合成了三十种与选择性
多巴胺-自身受体激动剂3-(3-羟苯基)-Nn-丙基
哌啶有关的化合物,并测试了其对中央
多巴胺-自身受体的刺激活性。3-(3-羟苯基)
哌啶部分似乎对于高效力和选择性是必不可少的。将另外的羟基引入芳族环的4位得到具有
多巴胺能活性但对自体受体缺乏选择性的化合物。3-(3-羟基苯基)-Nn-丙基
吡咯烷,3-(3-羟基)-Nn-丙基全氢a庚因和3-(3-羟基苯基)喹核苷均无活性。最有效的化合物是N-异丙基,Nn-丁基,Nn-戊基和N-苯乙基取代的3-(3-羟苯基)
