    • Provided are PDE1 inhibitors of Formula I, processes for their production, their use as pharmaceuticals, and pharmaceutical compositions comprising them. Previous publication WO 2009/075784 disclosed, among others, (6aR,9aS)-2-(4-(6-fluoropyridin-2-yl) benzyl)-5-methyl-3-(phenylamino)-5,6a,7,8,9,9a-hexahydrocyclopenta[4,5]imidazo[1,2-a]pyrazolo[4,3-e]pyrimidin-4(2H)-one as an inhibito of PDE1. This compound undergoes significant metabolism at several positions including the aniline ring and the cyclopentane ring. The current invention provides for Compounds of Formula I wherein such metabolism is attenuated by the substitution of hydrogen atoms for deuterium atoms at key locations discovered by the inventors.
    • 提供式I的PDE1抑制剂,其制备方法,其作为药物的用途,以及包含它们的药物组合物。 以前公开的WO 2009/075784公开了(6aR,9aS)-2-(4-(6-氟吡啶-2-基)苄基)-5-甲基-3-(苯基氨基)-5,6a, 8,9,9a-六氢环戊二烯并[4,5]咪唑并[1,2-a]吡唑并[4,3-e]嘧啶-4(2H) - 酮作为PDE1的抑制剂。 该化合物在包括苯胺环和环戊烷环在内的几个位置处经历显着的代谢。 本发明提供式I化合物,其中通过在发明人发现的关键位置用氢原子取代氘原子来减弱其代谢。
