Chemistry and Pharmacology of a Series of Unichiral Analogues of 2-(2-Pyrrolidinyl)-1,4-benzodioxane, Prolinol Phenyl Ether, and Prolinol 3-Pyridyl Ether Designed as α4β2-Nicotinic Acetylcholine Receptor Agonists

is changed. High α4β2 affinity and selectivity are also attained by meta hydroxylating the 3-pyridyl and the phenyl ethers of (S)-N-methylprolinol and the phenyl ether of (S)-2-azetidinemethanol, known α4β2 agonists, although the interaction mode of the aryloxymethylene substructure cannot be assimilated to that of benzodioxane. Indeed, the α4β2 and α3β4 functional tests well differentiate behaviors
通过打开二恶烷来设计2 R,2 'S -2-(1'-甲基-2'-吡咯烷基)-7-羟基-1,4-苯并二恶烷的一些非手性类似物,这是一种有效的选择性α4β2-nAChR部分激动剂。并用氮气代替羟基碳。将所得的3-吡啶基和米羟苯基醚具有高亲和力α4β2和良好的亚型选择性,如果OH选自苯基除去或吡啶氮的位置被改变了迷路。高α4β2亲和力和选择性也通过间位羟基化的3-吡啶基和苯基醚(达到小号) - ñ -methylprolinol和的苯基醚(小号)-2-氮杂环丁烷甲醇,已知的α4β2激动剂,尽管芳氧亚甲基亚结构的相互作用方式不能与苯并二恶烷的相互作用方式同化。确实,α4β2和α3β4功能测试很好地区分了结合测试同源的行为:N-甲基脯氨醇的3-羟基苯基和5-羟基-3-吡啶基醚都是α4β2完全激动剂,但只有后者是高度α4β2/α3β4选择性,而有效和选择性的部分α4β2激动作用是羟基苯并二恶烷衍生物及其两个开放的半刚性类似物的特征。
