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-氮杂双环烷类化合物、制备该类化合物的方法以及使用该类化合物的治疗方法。氮杂双环烷通常是氮杂双环庚烷、氮杂双环辛烷或氮杂双环壬烷。芳基烷基中的芳基是一个5-或6-成员环杂芳基,优选是3-吡啶基和5-嘧啶基,烷基通常是C1-4烷基。1-氮杂双环烷的3-位取代基是一种含有羰基基团的基团,例如酰胺、氨基甲酸酯、脲、硫酰胺、硫代氨基甲酸酯、硫脲或类似的官能团。该化合物在尼古丁乙酰胆碱受体(nAChRs)上表现出活性,特别是α7 nAChR亚型,并且对于调节神经递质和神经递质参与的配体的释放是有用的。还公开了预防或治疗条件和疾病的方法,包括中枢神经系统(CNS)疾病,这些疾病的特征是正常神经递质的改变。还公开了治疗炎症、自身免疫性疾病、疼痛和过度新血管生成的方法,例如与肿瘤生长相关的新血管生成。
