The present invention provides compounds of the formula
wherein R
1
and R
2
have meaning as defined herein in the specification. The compounds of formula (I) are adenosine A
2A
receptor antagonists and, thus, may be employed for the treatment of conditions and diseases mediated by the adenosine A
2A
receptor activity. Such conditions include, but are not limited to, diseases of the central nervous system such as depression, cognitive function diseases and neurodegenerative diseases such as Parkinson's disease, senile dementia as in Alzheimer's disease or psychoses and stroke. The compounds of the present invention may also be employed for the treatment of attention related disorders such as attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD), extra pyramidal syndrome, e.g., dystonia, akathisia, pseudoparkinsonism and tardive dyskinesia, and disorders of abnormal movement such as restless leg syndrome (RLS) and periodic limb movement in sleep (PLMS); cirrhosis, and fibrosis and fatty liver; dermal fibrosis in diseases such as scleroderma; and the mitigation of addictive behavior. In particular, the compounds of the present invention may be employed to improve motor-impairment due to neurodegenerative diseases such as Parkinson's disease.
本发明提供了以下式的化合物
其中R
1
和R
2
的含义如规范中所定义。式(I)的化合物是腺苷A
2A
受体拮抗剂,因此可用于治疗由腺苷A
2A
受体活性介导的疾病和病症。这些疾病包括但不限于中枢神经系统疾病,如抑郁症、认知功能疾病和神经退行性疾病,如帕金森病、老年性痴呆症、精神病和中风。本发明的化合物还可用于治疗注意力相关障碍,如注意力缺陷障碍(ADD)和注意力缺陷多动障碍(ADHD),额外锥体综合征,例如肌张力障碍、不安坐立、假性帕金森症和迟发性运动障碍,以及异常运动障碍,如不宁腿综合征(RLS)和睡眠中期肢体运动(PLMS);肝硬化、纤维化和脂肪肝;在硬皮病等疾病中的皮肤纤维化;以及对成瘾行为的缓解。特别是,本发明的化合物可用于改善由帕金森病等神经退行性疾病引起的运动障碍。
