Substituted amino derivatives represented by the formula: ##STR1## wherein R.sup.1 and R.sup.2 each stand for an acyclic hydrocarbon residue or an alicyclic hydrocarbon residue; R.sup.3 and R.sup.4 each stand for hydrogen or a hydrocarbon residue optionally containing hetero-atom(s); A stands for a carbon chain having two or more carbon atoms optionally containing ether linkage or sulfide linkage, which may be substituted and which may per se form a ring; X.sup.1 and X.sup.2 each stand for oxygen atom or sulfur atom; and Y stands for amino group or an organic residue bonded through nitrogen atom, which may form a ring by combining with a carbon atom constituting A; and their salts have anti-arrhythmic activity and are useful for prevention and treatment of a variety of arrhythmias.
由以下公式表示的取代氨基衍生物:##STR1## 其中R.sup.1和R.sup.2分别代表无环烃基残基或脂环烃基;R.sup.3和R.sup.4分别代表氢或可选地含有杂原子的烃基残基;A代表具有两个或更多碳原子的碳链,可选地含有醚键或硫醚键,可以被取代,并且可以自身形成环;X.sup.1和X.sup.2分别代表氧原子或硫原子;Y代表氨基团或通过氮原子结合的有机残基,可以通过与构成A的碳原子结合形成环;它们的盐具有抗心律失常活性,并且对于预防和治疗各种心律失常很有用。
