The present invention relates to a novel piperazine compound represented by the following general formula (I): ##STR1## wherein X stands for a hydrogen or halogen atom, an alkoxy, carboxy or alkoxycarbonyl group or a group R.sup.3 CO-- in which R.sup.3 stands for an alkyl group having 1 to 4 carbon atoms, R.sup.1 stands for a hydrogen atom or an alkyl group, and R.sup.2 stands for a hydrogen atom or an alkyl group. These compounds are valuable as immunopotentiators, such as for the treatment of chronic rheumatoid arthritis and other diseases accompanied by reduction or abnormal change of the immune function.
本发明涉及一种由以下通式(I)表示的新型哌嗪化合物:##STR1##其中X代表氢或卤素原子,烷氧基,羧基或烷氧羰基基团或R.sup.3 CO-基团,其中R.sup.3代表具有1至4个碳原子的烷基基团,R.sup.1代表氢原子或烷基基团,R.sup.2代表氢原子或烷基基团。这些化合物可用作免疫增强剂,例如用于治疗慢性类风湿性关节炎和其他伴随着免疫功能减退或异常变化的疾病。
