The invention relates to 2,6-piperazinedione derivatives of general formula I ##STR1## in which: A and B each denote a methylene radical or a carbonyl radical with the proviso, however, that A and B never simultaneously denote the same radical, R.sub.1 denotes a diphenylmethyl radical optionally substituted on the benzene rings with a halogen atom, a cyclohexyl radical, a pyridylmethyl group, or a benzyl radical optionally substituted with a halogen atom or with an alkoxy radical containing from 1 to 4 carbon atoms, R.sub.2 denotes a pyrimidinyl radical or a phenyl radical optionally substituted with a halogen atom, with an alkyl radical having from 1 to 4 carbon atoms, with a trifluoromethyl radical or with an alkoxy radical containing from 1 to 4 carbon atoms, n is an integer from 2 to 4, and their addition salts with a pharmaceutically acceptable inorganic or organic acid.
该发明涉及一般式I的2,6-哌嗪二酮衍生物,其中:A和B各自表示亚甲基基团或羰基基团,但A和B永远不同时表示相同的基团,R.sub.1表示二苯甲基基团,其在苯环上可选择地取代有卤原子、环己基基团、吡啶甲基基团或苄基基团,其可选择地取代有卤原子或含有1至4个碳原子的烷氧基基团,R.sub.2表示嘧啶基团或苯基基团,其可选择地取代有卤原子、含有1至4个碳原子的烷基基团、三氟甲基基团或含有1至4个碳原子的烷氧基基团,n为2至4的整数,以及它们与药学上可接受的无机或有机酸的加合盐。
