of thirty 2-(3-pyridylaminomethyl)azetidine, pyrrolidine and piperidine analogues as nicotinic acetylcholine receptor (nAChR) ligands was explored. In general, pyrrolidinyl and many azetidinyl compounds were found to bind with enhanced affinity relative to the piperidines. In the three series, the parallel structural changes (stereochemistry, N-methylation and/or chloro substitution) do not consistently
探索了一系列三十种2-(3-吡啶基氨基甲基)氮杂环丁烷,吡咯烷和哌啶类似物,作为烟碱型乙酰胆碱受体(nAChR)配体。通常,发现吡咯烷基和许多氮杂环丁烷基化合物相对于哌啶以增强的亲和力结合。在这三个系列中,平行的结构变化(立体化学,N-甲基化和/或氯取代)并不总是导致亲和力平行变化。皮下注射后,在小鼠的甩尾试验中,活性更高的化合物(K(i)亲和力值范围为8.9至90 nM)与尼古丁差不多。
