[Problem] A compound which is useful as a dopamine D1 receptor positive allosteric modulator (D1 PAM) is provided.
[Means for Solution] The present inventors have studied a compound which has a dopamine D1 receptor positive allosteric modulating activity and is useful as an active ingredient of a pharmaceutical composition for preventing and/or treating cognitive impairment, negative symptoms of schizophrenia, Parkinson's disease, Alzheimer's disease, Huntington's disease, drug addictions, or the like, and they have thus found that a heterocyclic acetamide compound has a dopamine D1 receptor positive allosteric modulating activity, thereby completing the present invention. The heterocyclic acetamide compound of the present invention has a dopamine D1 receptor positive allosteric modulating activity and can be used as an agent for preventing and/or treating cognitive impairment, negative symptoms of schizophrenia, Parkinson's disease, Alzheimer's disease, Huntington's disease, drug addictions, or the like.
[问题]本发明提供了一种可用作多巴胺D1受体正性异位调节剂(D1 PAM)的化合物。
[解决方法]本发明人研究了一种化合物,该化合物具有多巴胺 D1 受体正性全调节活性,可作为药物组合物的活性成分,用于预防和/或治疗认知障碍、精神分裂症的阴性症状、帕金森病、阿尔茨海默病、亨廷顿病、药物成瘾或类似疾病,并由此发现一种杂环乙酰胺化合物具有多巴胺 D1 受体正性全调节活性,从而完成了本发明。本发明的杂环乙酰胺化合物具有多巴胺D1受体正异位调节活性,可用作预防和/或治疗认知障碍、精神分裂症的阴性症状、帕金森病、阿尔茨海默病、亨廷顿病、药物成瘾或类似疾病的药物。
