The invention relates to novel 1,6-disubstituted pyrazolopyrimidinones, Formula (I) with Hc is a mono-, bi- or tricyclic heterocyclyl group, the ring members of which are carbon atoms and at least 1, preferably 1, 2 or 3, heteroatom(s), which are selected from the group of nitrogen, oxygen and sulphur, which is in the form of -S(O)r - with r being 0, 1 or 2, and - said heterocyclyl group is or comprises 1 non-aromatic, saturated, or partly unsaturated monocyclic ring which comprises at least 1 heteroatom as ring member and - said heterocyclyl group is bound to the scaffold by said 1 non- aromatic, saturated, or partly unsaturated monocyclic ring which comprises at least 1 heteroatom as ring member. According to one aspect of the invention the new compounds are for the manufacture of medicaments, in particular medicaments for the treatment of conditions concerning deficits in perception, concentration, learning or memory. The new compounds are also for the manufacture of medicaments for the treatment of Alzheimer's disease.
该发明涉及新型1,6-二取代吡唑吡嘧啶酮,化学式(I),其中Hc是一个单环、双环或三环杂环基团,其环成员为碳原子和至少1个,优选1个、2个或3个来自氮、氧和硫的杂原子,其以-S(O)r-的形式存在,其中r为0、1或2,所述杂环基团是或包括1个非芳香、饱和或部分不饱和的单环环,其中至少包含1个杂原子作为环成员,所述杂环基团通过所述至少包含1个杂原子作为环成员的非芳香、饱和或部分不饱和的单环环与支架相结合。根据该发明的一个方面,新化合物用于制造药物,特别是用于治疗感知、注意力、学习或记忆缺陷相关疾病的药物。新化合物还用于制造治疗阿尔茨海默病的药物。
