In accordance with the present invention, a novel class of substituted aryl compounds (containing ether, ester, amide, ketone or thioether substitution) that promote the release of ligands involved in neurotransmission have been discovered. In a particular aspect, compounds of the present invention are capable of modulating acetylcholine receptors. The compounds of the present invention are capable of displacing one or more acetylcholine receptor ligands, e.g., 3H-nicotine, from mammalian neuronal membrane binding sites. Invention compounds may act as agonists, partial agonists, antagonists or allosteric modulators of acetylcholine receptors. Therapeutic indications for compounds with activity as acetylcholine receptors include diseases of the central nervous system such as Alzheimer's disease and other diseases involving memory loss and/or dementia (including AIDS dementia); cognitive dysfunction (including disorders of attention, focus and concentration), disorders of extrapyramidal motor function such as Parkinson's disease, progressive supramuscular palsy, Huntington's disease, Gilles de la Tourette syndrome and tardive dyskinesia; mood and emotional disorders such as depression, anxiety and psychosis; substance abuse including withdrawal symptoms and substitution therapy; neurocrine disorders and dysregulation of food intake, including bulimia and anorexia; disorders of nociception and control of pain; autonomic disorders including dysfimction of gastrointestinal motility and function such as inflammatory bowel disease, irritable bowel syndrome, diarrhea, constipation, gastric acid secretion and ulcers; pheochromocytoma, cardiovascular dysfunction including hypertension and cardiac arrhythmias, as well as co-medication uses in surgical applications.
根据本发明,发现了一类新型的取代芳基化合物(包含醚、酯、酰胺、酮或硫醚取代),可以促进神经递质参与的配体的释放。在特定方面,本发明的化合物能够调节乙酰胆碱受体。本发明的化合物能够从哺乳动物神经元膜结合位点中取代一个或多个乙酰胆碱受体配体,例如3H-尼古丁。发明化合物可以作为乙酰胆碱受体的激动剂、部分激动剂、拮抗剂或变构调节剂。具有作为乙酰胆碱受体活性的化合物的治疗适应症包括中枢神经系统疾病,如阿尔茨海默病和其他涉及记忆丧失和/或痴呆的疾病(包括艾滋病痴呆);认知功能障碍(包括注意力、焦点和集中障碍);运动功能障碍,如帕金森病、进行性肌肉萎缩性侧索硬化症、亨廷顿病、吉尔斯·德·拉·图雷特综合征和迟发性运动障碍;情绪和情感障碍,如抑郁症、焦虑症和精神病;药物滥用,包括戒断症状和替代疗法;神经内分泌障碍和食物摄入的失调,包括暴食症和厌食症;疼痛感知和控制障碍;自主神经障碍,包括胃肠动力和功能障碍,如炎性肠病、肠易激综合征、腹泻、便秘、胃酸分泌和溃疡;嗜铬细胞瘤、心血管功能障碍,包括高血压和心律失常,以及在外科应用中的联用用途。
