The present invention relates to novel 1-aryl-4-methyl-[1,2,4]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 radiolabelled 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 1-芳基-4-甲基-[1,2,4]三唑并[4,3-a]-喹喔啉衍生物,该衍生物是磷酸二酯酶 2 (PDE2) 的抑制剂,其次是磷酸二酯酶 10 (PDE10) 的抑制剂,或者是磷酸二酯酶 2 和 10 两者的抑制剂。本发明还涉及包含此类化合物的药物组合物、制备此类化合物和组合物的工艺,以及将此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,如神经和精神疾病以及内分泌或代谢疾病。本发明还涉及放射性标记化合物,该化合物可用于利用正电子发射断层扫描(PET)对组织中的 PDE2 酶进行成像和量化。本发明还涉及包含此类化合物的组合物,制备此类化合物和组合物的工艺,使用此类化合物和组合物对组织、细胞或宿主进行体外或体内成像,以及所述化合物的前体。
