The invention relates to novel 6-Cycloalkyl-pyrazolopyrimidinones according to formula (I) wherein R1 is a 5 or 6 membered aromatic heteroaryl-group, R2 is an optional substituent, D is optionally substituted cyclopentyl, cyclohexyl, tetrahydrofuranyl, tetrahydropyranyl or 2-, 3- or 4-pyridyl, m= 1 or 2 and n is 0, 1 or 2. The new compounds are for use as the active entity of medicaments or for the manufacture of medicaments respectively, in particular medicaments for the treatment of conditions concerning deficits in perception, concentration, learning or memory. Such conditions may for example be associated with Alzheimers disease, schizophrenia and other diseases. The new compounds are also for example for the manufacture of medicaments and/or for use in the treatment of these diseases, in particular for cognitive impairment associated with such disease. The compounds of the invention show PDE9 inhibiting properties.
该发明涉及根据式(I)的新型6-环烷基吡唑吡嘧啶酮,其中R1是5或6成员芳香杂环基团,R2是可选取代基,D是可选取代的环戊基、环己基、四氢呋喃基、四氢吡喃基或2-、3-或4-吡啶基,m=1或2,n为0、1或2。这些新化合物可用作药物的活性成分或用于制造药物,特别是用于治疗涉及感知、注意力、学习或记忆缺陷的疾病的药物。这些疾病可能与阿尔茨海默病、精神分裂症和其他疾病有关。这些新化合物还可用于制造药物和/或用于治疗这些疾病,特别是与此类疾病相关的认知障碍。该发明的化合物显示PDE9抑制特性。
