The derivatives of acyl-piperazinyl-pyrimidines of general formula (I), where X is O or S; R1 is alkoxy or trifluoromethyl; R2 is alkyl, cycloalkyl, heterocycloalkyl, aryl, arylalkyl, heteroaryl, or heteroarylalkyl, show activity in the central nervous system. Compounds of general formula (I) in which X is O can be obtained by reacting a derivative of pyrimidine with a derivative of piperazine or by reacting a derivative of piperazinyl-pyrimidine with a carboxylic acid or a salt or derivative thereof. Compounds of general formula (I) in which X is S can be obtained by reacting (I) in which X is O with Lawesson's reagent or with phosphorous pentasulphide. The compounds (I) show sedative activity, anticonvulsant, sleep-inducing or general anaesthetic activity and can be applied in human or veterinary medicine
通式为(I)的酰基哌嗪基嘧啶衍生物的导数,其中X为O或S; R1为烷氧基或三氟甲基; R2为烷基,环烷基,杂环烷基,芳基,芳基烷基,杂芳基或杂芳基烷基,表现出中枢神经系统的活性。通式(I)中X为O的化合物可通过将嘧啶衍生物与哌嗪衍生物的衍生物反应或将哌嗪基嘧啶的衍生物与羧酸或其盐或衍生物反应而得到。通式(I)中X为S的化合物可通过将X为O的(I)与Lawesson试剂或五硫化二磷反应而得到。这些化合物(I)表现出镇静作用,抗惊厥,催眠或全身麻醉作用,可应用于人类或兽医学。
