Substituted benzenesulfonylureas and -thioureas as antiarrhythmics.

摘要

There are described substituted benzenesulphonylureas and -thioureas of the formula I where R(1) is H, (cyclo)(CH2)a(fluoro)alk(en)yl, R(2) is H, Hal, (fluoro)(mercapto)(CH2)e(cyclo)alk(oxy)(yl), NR(4)R(5) where R(4) and R(5) together are a (CH2)2-7 chain, or R(4), R(5), R(6) are H, (alkyl)(cyclo)(fluoro)alk(en)yl, E is O, S; Y is -[CR(7)2]n-R(3) B is (C3-C6)-alkenyl, or R(3) is X is H, Hal, alkyl; Z is Hal, (cyclo)alk(yl)(oxy). Compounds I are used for the treatment of cardiac arrhythmias and for the prevention of sudden heart death caused by arrhythmia and can therefore be used as antiarrhythmics. They are particularly suitable in those cases in which arrhythmias are the result of constriction of a coronary vessel, such as in angina pectoris or in acute cardiac infarct.
