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.
提供了公式I的PDE1抑制剂,其生产过程,它们作为药物的用途以及包含它们的制药组合物。之前的出版物WO 2009/075784披露了(6aR,9aS)-2-(4-(6-氟吡啶-2-基)苯甲基)-5-甲基-3-(苯基氨基)-5,6a,7,8,9,9a-六氢-环戊[4,5]咪唑[1,2-a]吡嗪并[4,3-e]嘧啶-4(2H)-酮作为PDE1的抑制剂。该化合物在苯胺环和环戊烷环等多个位置经历了显著的代谢。本发明提供了公式I的化合物,其中通过在发明人发现的关键位置用氘代替氢原子来减弱这种代谢。
