    • 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.
    • 嘧啶二酮衍生物化合物具有其中苯基部分和嘧啶二酮部分通过包含含有两个氮原子的烷基链的连接结构连接的碱性主链。 该连接结构由表示,其中A是 - (CH 2)n - , - CO-或-O-(CH 2)m - ; R 1和R 2各自独立地为氢原子或可以被羟基取代的低级烷基,或者R 1和R 2可以相互连接形成亚烷基链,从而形成杂环结构; R5是卤素原子,羟基,低级烷氧基羰基,可被低级烷氧基取代的低级烷氧基或可被羟基取代的低级烷基,或R5可以与 R1形成亚烷基链,从而形成杂环结构; n是0,1,2或3(当R5是羟基时,n是等于0); m为0,1,2或3; 并且k为0,1,2或3(然而,其中A为-O-(CH 2)m - 且R 5为羟基的化合物不包括在嘧啶二酮衍生物中]]。 嘧啶二酮衍生物及其酸加成盐可用于治疗心律失常。
