    • The present invention relates to amide and urea derivatives of heteroaryl- substituted diazatricycloalkanes, of the Formula (I) with the definition as set out in the description pharmaceutical compositions including the compounds, methods of preparing the compounds, and methods of treatment using the compounds. More specifically, the methods of treatment involve modulating the activity of the α7 nAChR subtype by administering one or more of the compounds to treat or prevent disorders mediated by the α7 nAChR subtype. The diazatricycloalkanes typically consist of a 1-azabicyclooctane fused to pyrrolidine ring. The substituent heteroaryl groups are 5- or 6-membered ring heteroaromatics, such as 3-pyridinyl and 5-pyrimidinyl moieties, which are attached directly to the diazatricycloalkane. The secondary nitrogen of the pyrrolidine moiety is substituted with an arylcarbonyl (amide type derivative) or an arylaminocarbonyl (N- arylcarbamoyl) (urea type derivative) group. The compounds are beneficial in therapeutic applications requiring a selective interaction at certain nAChR subtypes. That is, the compounds modulate the activity of certain nAChR subtypes, particularly the α7 nAChR subtype, and do not have appreciable activity toward muscarinic receptors. Radiolabeled versions of the compounds can be used in diagnostic methods.
    • 本发明涉及式(I)的杂芳基取代的二氮三环环烷烃的酰胺和脲衍生物,其定义如本说明书所述的药物组合物包括化合物,制备化合物的方法和使用该化合物的治疗方法。 更具体地,治疗方法包括通过施用一种或多种化合物来治疗或预防由a7 nAChR亚型介导的病症来调节a7 nAChR亚型的活性。 二氮杂环烷烃通常由与吡咯烷环稠合的1-氮杂双环辛烷组成。 取代基杂芳基是5-或6-元环杂芳族化合物,例如3-吡啶基和5-嘧啶基部分,其直接连接到二氮杂环烷烃上。 吡咯烷部分的仲氮被芳基羰基(酰胺型衍生物)或芳基氨基羰基(N-芳基氨基甲酰基)(脲型衍生物)基团取代。 这些化合物在需要在某些nAChR亚型选择性相互作用的治疗应用中是有益的。 也就是说,化合物调节某些nAChR亚型的活性,特别是a7 nAChR亚型,并且对毒蕈碱受体没有明显的活性。 化合物的放射性标记版本可用于诊断方法。
