The invention relates to pyrimidone derivative represented by formula (I) or a salt thereof:
wherein:
R1 represents
* a C6,10 aryl group,
* a heterocyclic ring having 1-4 hetero atoms selected from oxygen atom, sulfur atom, and nitrogen atom, and having total ring-constituting atoms of 5-10, or
* a C1-6 alkyl group substituted by 1 to 3 substituents selected from
a hydroxyl group,
a C3-6 cycloalkyl group
a C6,10 aryl group and
a heterocyclic ring as defined above,
the C6,10 aryl groups and heterocyclic rings being optionally substituted by 1 to 3 substituents.
The invention relates also to a medicament comprising the said derivative or a salt thereof as an active ingredient which is used for preventive and/or therapeutic treatment of a neurodegenerative disease caused by abnormal activity of GSK3β, such as Alzheimer's disease, Parkinson's disease, frontoparietal dementia, corticobasal degeneration, Pick's disease, cerebrovascular accidents, brain and spinal trauma, and peripheral neuropathies.
本发明涉及式 (I) 所代表的嘧啶酮衍生物或其盐:
其中
R1 代表
* C6,10 芳基、
* 具有 1-4 个杂质原子的杂环,这些杂质原子选自氧原子、硫原子和氮原子,组成环的总原子数为 5-10 个,或
* 被 1 至 3 个选自以下的取代基取代的 C1-6 烷基
羟基
C3-6 环烷基
