The present invention relates to novel l-aryl-4-methyl-[l,2,4]triazolo[4,3-a]- quinoxaline derivatives as inhibitors of phosphodiesterase 2 (PDE2) and to a lesser extent of phosphodiesterase 10 (PDE10) or as inhibitors of both, phosphodiesterases 2 and 10. The invention is also directed to pharmaceutical compositions comprising such compounds, to processes for preparing such compounds and compositions, and to the use of such compounds and compositions for the prevention and treatment of disorders in which PDE2 is involved, or disorders in which both PDE2 and PDE10 are involved, such as neurological and psychiatric disorders, and endocrinological or metabolic diseases. The present invention also relates to radiolabeled compounds which may be useful for imaging and quantifying the PDE2 enzyme in tissues, using positron- emission tomography (PET). The invention is also directed to compositions comprising such compounds, to processes for preparing such compounds and compositions, to the use of such compounds and compositions for imaging a tissue, cells or a host, in vitro or in vivo and to precursors of said compounds.
本发明涉及新型的l-芳基-4-甲基-[1,2,4]三唑并[4,3-a]-喹喔啉衍生物,作为磷酸二酯酶2(PDE2)的抑制剂,以及在较小程度上作为磷酸二酯酶10(PDE10)的抑制剂或作为磷酸二酯酶2和10的双重抑制剂。该发明还涉及包含这类化合物的药物组合物,用于制备这类化合物和组合物的方法,以及将这类化合物和组合物用于预防和治疗涉及PDE2的疾病或涉及PDE2和PDE10的疾病,如神经和精神疾病,内分泌或代谢性疾病。本发明还涉及可能用于组织中PDE2酶的成像和定量的放射标记化合物,使用正电子发射断层扫描(PET)。该发明还涉及包含这类化合物的组合物,用于制备这类化合物和组合物的方法,将这类化合物和组合物用于体内或体外成像组织、细胞或宿主,并涉及这类化合物的前体。
