tertiary bases (2, 4) with arecoline (5) and arecolone (6) or by isosteric substitution of the phenyl ring of DMPP, has been synthesized. Hybridization afforded compounds that, both as tertiary bases and as iodomethylates, have no affinity for the nicotinic receptor. On the contrary, isosteric substitution gave compounds that maintain affinity for the receptor; among them, two tertiary bases (37, 38)
通过将N1-乙酰基-N4-二甲基哌嗪碘化物(1,ADMP)和N1-苯基-N4-二甲基哌嗪碘化物(3,DMPP)或相应的叔碱基(2, 4)用槟榔碱(5)和槟榔酮(6)或通过等规取代DMPP的苯环。杂交提供了既作为叔碱又作为碘甲基化物的化合物,其对烟碱样受体没有亲和力。相反,等位取代使化合物对受体保持亲和力。其中,两个叔碱基(37、38)对烟碱样受体具有纳摩尔级的亲和力。这些异构化合物的药理学特征非常有趣,因为它们的外周和中枢作用存在差异,
