Compounds, pharmaceutical compositions including the compounds, and methods of preparation and use thereof are disclosed. The compounds are N-aryl diazaspirocyclic compounds, bridged analogs of N-heteroaryl diazaspirocyclic compounds, or prodrugs or metabolites of these compounds. The aryl group can be a five- or six-membered heterocyclic ring (heteroaryl). The compounds and compositions can be used to treat and/or prevent a wide variety of conditions or disorders, particularly those disorders characterized by dysfunction of nicotinic cholinergic neurotransmission, including disorders involving neuromodulation of neurotransmitter release, such as dopamine release. CNS disorders, which are characterized by an alteration in normal neurotransmitter release, are another example of disorders that can be treated and/or prevented. The compounds and compositions can also be used to alleviate pain. The compounds can: (i) alter the number of nicotinic cholinergic receptors of the brain of the patient, (ii) exhibit neuroprotective effects and (iii) when employed in effective amounts, not result in appreciable adverse side effects (e.g., side effects such as significant increases in blood pressure and heart rate, significant negative effects upon the gastro-intestinal tract, and significant effects upon skeletal muscle).
本文公开了N-芳基二氮杂螺环化合物、N-杂芳基二氮杂螺环化合物的桥接类似物、以及这些化合物的前药或代谢物的制备和使用方法。芳基可以是五元或六元杂环(杂芳基)。这些化合物和组合物可用于治疗和/或预防各种疾病或障碍,特别是那些以尼古丁胆碱能神经递质功能障碍为特征的障碍,包括涉及神经递质释放的神经调节障碍,例如多巴胺释放。中枢神经系统障碍是另一个可以治疗和/或预防的例子,其特征是正常神经递质释放的改变。这些化合物和组合物也可用于缓解疼痛。这些化合物可以:(i)改变患者的大脑中尼古丁胆碱能受体的数量,(ii)表现出神经保护作用,以及(iii)在有效剂量下,不会导致明显的不良副作用(例如,明显增加血压和心率、对胃肠道的明显负面影响以及对骨骼肌的明显影响等副作用)。
