The present invention relates to new substituted pyrazolo [3,4-d]pyrimidine compounds of general formula (I), having a great affinity for sigma receptors, especially sigma-1 receptor, as well as to the process for the preparation thereof, to compositions comprising them, and to their use as medicaments for the treatment of i.a. pain.
n is selected from 1, 2, 3 or 4; R1 represents a carbon-linked optionally substituted aryl or heteroaryl radical; R2 and R3 independently represent a hydrogen atom, an optionally substituted aliphatic, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, heterocyclyl or heterocyclylalkyl radical, or R2 and R3 together with the bridging nitrogen form an optionally substituted heterocyclyl or heteroaryl radical.
本发明涉及一种新的取代吡唑[3,4-d]嘧啶化合物,其通式为(I),具有对σ受体,特别是σ-1受体的高亲和力,以及其制备方法,包括它们的组成物,以及它们作为治疗药物的用途。其中n选自1、2、3或4;R1代表一个碳链连接的可选择取代的芳基或杂环芳基基团;R2和R3独立地代表氢原子,一个可选择取代的脂肪烃基、环烷烃基、环烷基烷基、芳基、芳基烷基、杂环芳基、杂环芳基烷基、杂环基或杂环基烷基基团,或者R2和R3与桥接氮一起形成一个可选择取代的杂环基或杂环芳基基团。
