The present invention relates to 3-substituted-2-(arylalkyl)-1-azabicycloalkanes, methods of preparing the compounds and methods of treatment using the compounds. The azabicycloalkanes generally are azabicycloheptanes, azabicyclooctanes, or azabicyclononanes. The aryl group in the arylalkyl moiety is a 5- or 6-membered ring heteroaromatic, preferably 3-pyridinyl and 5-pyrimidinyl moieties, and the alkyl group is typically a C
1-4
alkyl. The substituent at the 3-position of the 1 -azabicycloalkane is a carbonyl group-containing moiety, such as an amide, carbamate, urea, thioamide, thiocarbamate, thiourea or similar functionality. The compounds exhibit activity at nicotinic acetylcholine receptors (nAChRs), particularly the α7 nAChR subtype, and are useful towards modulating neurotransmission and the release of ligands involved in neurotransmission. Methods for preventing or treating conditions and disorders, including central nervous system (CNS) disorders, which are characterized by an alteration in normal neurotransmission, are also disclosed. Also disclosed are methods for treating inflammation, autoimmune disorders, pain and excess neovascularization, such as that associated with tumor growth.
本发明涉及3-取代-2-(芳基烷基)-1-氮杂环烷化合物、制备这些化合物的方法以及使用这些化合物的治疗方法。氮杂环烷通常是氮杂七环烷、氮杂八环烷或氮杂壬环烷。芳基烷基中的芳基是一个5或6元环的杂芳族,优选为3-吡啶基和5-嘧啶基,烷基通常是C1-4烷基。1-氮杂环烷的3位取代基是含有羰基的基团,例如酰胺、氨基甲酸酯、脲、硫脲、硫代氨基甲酸酯、硫脲或类似的官能团。这些化合物在尼古丁乙酰胆碱受体(nAChRs),特别是α7 nAChR亚型上表现出活性,并且对调节神经递质和神经递质参与的配体的释放有用。还公开了预防或治疗中枢神经系统(CNS)疾病等具有正常神经递质改变的疾病和疾病的方法。还公开了治疗炎症、自身免疫性疾病、疼痛和过度新生血管化的方法,例如与肿瘤生长相关的新生血管化。
