The present invention relates to a novel piperazinyl-propyl-pyrazole derivative, a method of its preparation and a pharmaceutically acceptable composition comprising the same. The novel piperazinyl-propyl-pyrazole derivative of the present invention has superior selective affinity for dopamine D4 receptor, can effectively inhibit psychotic behavior (cage climbing) induced by apomorphine, and has relatively low adverse effects in mouse rotarod test. Therefore, it can be developed as a therapeutic agent for the treatment and prevention of central nervous system (CNS) disorders, in particular, schizophrenia, attention deficit hyperactivity disorder, depression, stress diseases, panic disorder, phobia, obsessive-compulsive disorder, posttraumatic stress disorder, cognitive disorder, Alzheimer's disease, Parkinson's disease, anxiety, paraphrenia, mania, seizure disorder, personality disorder, migraine, drug addiction, alcohol addiction, obesity, eating disorder, and sleeping disorder.
本发明涉及一种新型哌嗪基丙基吡唑衍生物、其制备方法以及包含该衍生物的药学上可接受的组合物。本发明的新型哌嗪基丙基吡唑衍生物具有对多巴胺D4受体的优异选择性亲和力,能够有效抑制阿泼吗啡引起的精神病行为(笼子攀爬),并在小鼠转杆试验中具有相对较低的不良反应。因此,它可以作为治疗和预防中枢神经系统(CNS)疾病的治疗剂,特别是精神分裂症、注意力缺陷多动障碍、抑郁症、压力疾病、惊恐障碍、恐惧症、强迫症、创伤后应激障碍、认知障碍、阿尔茨海默病、帕金森病、焦虑症、妄想症、躁狂症、癫痫、人格障碍、偏头痛、药物成瘾、酒精成瘾、肥胖症、进食障碍和睡眠障碍的治疗剂开发。
