  Pyrazolo[4,3-d]pyrimidin-7(6H)-one derivatives represented by the general formula (I), wherein R1 represents hydrogen atom or methyl; when R1 represents hydrogen atom, then R2 represents cyclopentyl, tetrahydropyranyl, cyclohexyl, or cyclohexyl substituted with 1 or 2 halogen atoms; when R1 represents methyl, then R2 represents cyclopentyl; R3 is selected from the group consisting of phenyl unsubstituted or substituted with 1 to 3 substituents selected from F, CI, Br, I, and OCH3; and 6- to 10-membered heteroaryl with 1 to 3 heteroatoms selected independently form O, N and S; and Q represents C1 -C3-alkylene group, which is unsubstituted or substituted with 1 to 3 C1 -C3-alkyl groups; and their salts. The compounds are PDE9A inhibitors useful as medicaments, in particular for treatment of cognitive function disorders and neurodegenerative diseases.

  通用公式（I）表示的吡唑并[4,3-d]嘧啶-7(6H)-酮衍生物，其中R1代表氢原子或甲基；当R1代表氢原子时，R2代表环戊基、四氢吡喃基、环己基或带有1或2个卤原子的环己基；当R1代表甲基时，R2代表环戊基；R3选自苯基（未取代或取代为1至3个来自F、Cl、Br、I和OCH3的取代基）和1至3个异原子（独立选择自O、N和S）的6至10元杂环烷基；Q代表C1-C3-烷基烯基，未取代或取代为1至3个C1-C3-烷基基团；及其盐。这些化合物是PDE9A抑制剂，可作为药物使用，特别用于治疗认知功能障碍和神经退行性疾病。
