  Conformationally restrained carbamoylcholine homologues. Synthesis, pharmacology at neuronal nicotinic acetylcholine receptors and biostructural considerations

  摘要：

  Exploration of small selective ligands for the nicotinic acetylcholine receptors (nAChRs) based on acetylcholine (ACh) has led to the development of potent agonists with clear preference for the 042 nAChR, the most prevalent nAChR subtype in the central nervous system. In this work we present the continuation of these efforts aimed at increasing this subtype selectivity by introduction of conformational restriction in the carbamoylcholine homologue, 3-(dimethylaminobutyl) dimethylcarbamate (DMABC). Our results highlight the importance of the N-carbamoyl substitution in alpha(4)beta(2)-subtype selectivity. Moreover, we have confirmed the non-linear conformation of DMABC bound to nAChRs suggested by recent crystal structures of the compound in complex with the Lymnaea stagnalis ACh binding protein.
