Abstract:
The present invention provides 1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-ones and 1,5-dihydro-4H-pyrazolo[4,3-c]pyridin-4-ones of formula (I) as PDE1 inhibitors and their use as a medicament, in particular for the treatment of neurodegenerative disorders and psychiatric disorders.

Claim (Index 1):
A compound of formula (I): wherein:\n Y is N or CH; \n R 1  is selected from the group consisting of linear or branched C 2 -C 8  alkyl, saturated monocyclic C 3 -C 8  cycloalkyl, oxetanyl, tetrahydrofuranyl and tetrathydropyranyl; all of which can be substituted one or more times with one or more substituents selected from the group consisting of methyl, fluorine, hydroxy, cyano and methoxy; \n R 2  is:\n (a) selected from the group consisting of linear or branched C 1 -C 8  alkyl, phenyl, benzo[1,3]dioxole and saturated monocyclic C 3 -C 8  cycloalkyl; or \n (b) phenyl substituted one or more times with one or more substituents selected from the group consisting of halogen, C 1 -C 3  alkyl and methoxy; or \n (c) pyridyl substituted with a substituent selected from the group consisting of halogen, C 1 -C 3  alkyl, C 1 -C 3  alkoxy, C 1 -C 3  fluoroalkoxy, C 3 -C 4  cycloalkoxy and C 4 -C 5  methylcycloalkoxy; or \n (d) selected from the group consisting of 5-membered heteroaryls substituted with C 1 -C 3  alkyl; \n \n and \n R 3  is selected from the group consisting of linear or branched C 1 -C 3  alkyl and saturated monocyclic C 3 -C 8  cycloalkyl; which can each be optionally substituted with a substituent selected from halogen, C 1 -C 3  alkoxy, phenyl, dialkylamine and oxetane; \n or a tautomer or pharmaceutically acceptable salt thereof.
