A pyrimidinedione derivative compound has a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a linking structure comprising an alkyl chain containing two nitrogen atoms. This linking structure is represented by ##STR1## [wherein A is --(CH.sub.2).sub.n --, --CO-- or --O--(CH.sub.2).sub.m --; each of R.sup.1 and R.sup.2 is independently a hydrogen atom or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.1 and R.sup.2 may be so linked with each other as to make an alkylene chain and thus form a heterocyclic structure; R.sup.5 is a halogen atom, a hydroxyl group, a lower alkyloxycarbonyl group, a lower alkyloxy group which may be substituted by a lower alkyloxy group, or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.5 may be so linked with R.sup.1 as to make an alkylene chain and thus form a heterocyclic structure; n is 0, 1, 2 or 3 (when R.sup.5 is the hydroxyl group, n.noteq.0); m is 0, 1, 2 or 3; and k is 0, 1, 2 or 3 (however, a compound in which A is --O--(CH.sub.2).sub.m -- and R.sup.5 is the hydroxyl group is excluded from the pyrimidinedione derivative)]. The pyrimidinedione derivative and its acid addition salt are useful for a medical treatment of cardiac arrhythmias.
一种嘧啶二酮衍生物化合物具有一种基本骨架,其中苯基部分和嘧啶二酮部分由包含两个氮原子的烷基链连接的连接结构连接。该连接结构由##STR1##表示[其中A是--(CH.sub.2).sub.n --,--CO--或--O--(CH.sub.2).sub.m --;R.sup.1和R.sup.2中的每一个独立地是氢原子或可能被羟基取代的较低烷基基团,或者R.sup.1和R.sup.2可能被连接在一起形成烷基链并因此形成杂环结构;R.sup.5是卤素原子、羟基、较低烷氧羰基基团、可能被较低烷氧基取代的较低烷氧基团,或者可能被羟基取代的较低烷基基团,或者R.sup.5可能与R.sup.1连接形成烷基链并因此形成杂环结构;n为0、1、2或3(当R.sup.5为羟基时,n不等于0);m为0、1、2或3;k为0、1、2或3(然而,其中A为--O--(CH.sub.2).sub.m --且R.sup.5为羟基的化合物被排除在嘧啶二酮衍生物之外)]. 该嘧啶二酮衍生物及其酸盐加合物对治疗心律失常具有医疗用途。
