The present invention relates to (1- or 2- and/or 5 and/or 7-substituted)-(3-oxy)-(4H,4-imino, 4-thioxo or 4-oxo)-pyrazolo[3,4-d]pyrimidin-6-ones, e.g., a compound of formula II as described below, processes for their production, their use as pharmaceuticals and pharmaceutical compositions comprising them. Of particular interest are novel compounds useful as inhibitors of phosphodiesterase 1 (PDE1), e.g., in the treatment of diseases involving disorders of the dopamine D1 receptor intracellular pathway, such as Parkinson's disease, depression, narcolepsy, damage to cognitive function, e.g., in schizophrenia, or disorders that may be ameliorated through enhanced progesterone-signaling pathway, e.g., female sexual dysfunction.
本发明涉及(1-或2-和/或5和/或7-取代)-(3-氧基)-(4H,4-亚胺基、4-硫代氧基或4-氧基)-吡唑并[3,4-d]嘧啶-6-酮,例如,如下所述的II式化合物,其生产方法,它们作为药物的用途以及包含它们的药物组合物。特别感兴趣的是作为磷酸二酯酶1(PDE1)抑制剂的新型化合物,例如,用于治疗涉及多巴胺D1受体胞内途径紊乱的疾病,如帕金森病、抑郁症、嗜睡症、损害认知功能,例如在精神分裂症中,或通过增强孕激素信号途径改善的疾病,例如女性性功能障碍。
