The so-called beta conformer of dopamine has been proposed to be involved in agonist--receptor interactions at several sites in the dopaminergic nervous system. Further to evaluate this proposal, rigid congeners of the beta conformer derived from linearly and angularly annelated octahydrobenzoquinolines have been synthesized. Certain N-alkylated trans-angularly annelated systems exhibited unusually

多巴胺样效应,但这些化合物在各种CNS效应测定中均无活性。这些化合物将中枢神经系统作用与某些潜在的外周作用清楚地分开了。
