Disclosed are novel bis-dioxopiperazine derivatives, process for their preparation, antitumor agents comprising them and compositions containing them.
The bis-dioxopiperazine derivatives are represented by the following general formula (I):
wherein R, represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms; R2 represents a hydrogen atom or a group of
R3 and R., which are respectively independent and are the same or different, represent respectively a lower alkyl group having 1 to 4 carbon atoms, a cycloalkyl group having 3 to 7 carbon atoms or a heterocyclic radical selected from the group consisting of substituted or unsubstituted piperidino, substituted or unsubstituted piperazino, substituted or unsubstituted morpholino and substituted or unsubstituted thiomorpholino, or R3 and R. are bonded together to form a group of
which represents a cyclic amino group selected from the group consisting of substituted or unsubstituted pyrrolidino, substituted or unsubstituted piperidino, substituted or unsubstituted piperazino, substituted or unsubstituted morpholino, substituted or unsubstituted thiomorpholino and substituted or unsubstituted thiadiazino; and the substituents of the heterocyclic radical and the cyclic amino group are selected from the group consisting of a lower alkyl group having 1 to 4 carbon atoms, oxo and phenyl, said cyclic amino group being not morpholino when R, is a hydrogen atom and R2 is the group of
本发明公开了新型双-二氧代哌嗪衍生物、其制备工艺、包含这些衍生物的抗肿瘤药物以及含有这些衍生物的组合物。
双-二氧代哌嗪衍生物由以下通式(I)表示:
其中 R,代表氢原子或具有 1 至 4 个碳原子的低级烷基; R2 代表氢原子或一个由 R3 和 R.组成的基团。
分别独立且相同或不同的 R3 和 R.分别代表具有 1 至 4 个碳原子的低级烷基、具有 3 至 7 个碳原子的环烷基或选自由取代或未取代的哌啶基、取代或未取代的哌嗪基、取代或未取代的吗啉基和取代或未取代的硫代吗啉基组成的组中的杂环基,或 R3 和 R.键合在一起形成一个基团,该基团代表选自由取代或未取代的哌啶基、取代或未取代的哌嗪基、取代或未取代的吗啉基和取代或未取代的硫代吗啉基组成的组中的杂环基。
代表环状氨基,选自由取代或未取代的吡咯烷基、取代或未取代的哌啶基、取代或未取代的哌嗪基、取代或未取代的吗啉基、取代或未取代的噻吗啉基和取代或未取代的噻二嗪基组成的组;杂环基和环状氨基的取代基选自具有 1 至 4 个碳原子的低级烷基、氧代和苯基组成的组,当 R 为氢原子且 R2 为以下基团时,所述环状氨基不是吗啉基
