Abstract: The invention relates to novel 1,6-disubstituted pyrazolopyrimidinones of formula (I), in which Hc is a tetrahydropyranyl-group and R1 is the group V—W—*, whereby V and W independently of each other may be an aryl group or an heteroaryl group, which independently of each other may optionally be substituted. According to one aspect of the invention the new compounds are for use as medicaments or 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 and/or for use in the treatment of e.g. Alzheimer's disease, in particular for cognitive impairment associated with Alzheimer's disease.

Abstract: The invention relates to novel 1,6-disubstituted pyrazolopyrimidinones, wherein i.) the nitrogen atom of the pyrazolo-group that is next to the pyrimidino-group is attached to a non-aromatic, organic heterocycle having at least one ring hetero atom selected from O, N and S and ii.) to the C-atom between the two nitrogen atoms of the pyrimidinone-ring a second substituent is bound via an optionally substituted methylene-bridge. 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.
