Abstract
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.
