-C
8
-cycloalkyl group being selected from the group of cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptanyl and cyclooctanyl; and the members of the C

-cycloalkenyl group, being selected from cyclobutenyl, cyclopentenyl, cyclohexenyl, cycloheptenyl, cyclooctenyl, cyclopentadienyl, cyclohexadienyl, cycloheptadienyl, cyclooctadienyl, cycloheptatrienyl, cyclooctathenyl, cyclooctatetraenyl. The new compounds shall be used for the manufacture of medicaments, in particular medicaments for improving perception, concentration, learning and/or memory in patients in need thereof. Chemically, the compounds are characterised as pyrazolopyrimidinones with a cycloalkyl-moiety directly bound to the 1 position of the pyrazolopyrimidinone and a second substituent in the 6 position which is bound via an optionally substituted methylene-bridge. Further aspects of the present invention refer to a process for the manufacture of the compounds and their use for producing medicaments.
该发明涉及具有以下结构的新型环烷基或环烯基取代的吡唑吡咪啉酮化合物(I),其中Ā选自A1组中的C3-C8环烷基或C4-C8环烯基,其中C3-C8环烷基组成员选自环丙基、环丁基、环戊基、环己基、环庚基和环辛基;而C4-C8环烯基组成员选自环丁烯基、环戊烯基、环己烯基、环庚烯基、环辛烯基、环戊二烯基、环己二烯基、环庚二烯基、环辛二烯基、环庚三烯基、环辛烷基、环辛四烯基。这些新化合物可用于制造药物,特别是用于改善患者感知、注意力、学习和/或记忆的药物。从化学上讲,这些化合物被描述为在吡唑吡咪啉酮的1位上直接连接有环烷基基团,并且在6位上通过一个可选取代的亚甲基桥连接有第二取代基。该发明的进一步方面涉及一种制造这些化合物的方法以及它们用于生产药物的用途。
