Several different heterocyclic systems were compared as PDE5 inhibitor scaffolds. In addition to the known 3H-imidazo[5,1-f][1,2,4]triazin-4-ones and pyrazolopyrimidinones, isomeric imidazo[1,5-a][1,3,5]triazin-4(3H)-ones were also shown to be potent and selective PDE inhibitor scaffolds with in vivo activity. SAR trends were elucidated for sulfonamide derivatives with generality across different scaffolds.

The invention relates to novel imidazo[1,3,5]triazinones of the general formula (I), to a method for their production and to their use as medicaments, in particular as inhibitors of cyclic GMP metabolising phosphodiesterases.
