Benzenesulfonylureas and -thioureas of the formula I
where R(1) in N or (fluoro)methyl, R(2) is H, Hal or (fluoro)(mercapto)alk(oxy)yl, E is O or S, Y is —[CR(3)2]n—, where R(3)=H or alkyl and n=1-4, X is H, Hal or alkyl and Z is Hal, NO2 or alk(yl)oxy, are described.
The compounds I are used for treatment of disturbances in cardiac rhythm and prevention of sudden cardiac death caused by arrhythmia, and can therefore be used as antiarrhythmics. They are particularly suitable for those cases where arrhythmias are a consequence of a narrowing of a coronary vessel, such as angina pectoris or acute cardiac infarction.
苯磺酰脲和-硫脲的化学式I,其中R(1)为N或(氟)甲基,R(2)为H、卤素或(氟)(巯基)烷氧基,E为O或S,Y为—[CR(3)2]n—,其中R(3)=H或烷基,n=1-4,X为H、卤素或烷基,Z为卤素、NO2或烷氧基。这些化合物I被用于治疗心律失常和预防由心律失常引起的突发性心脏死亡,并因此可用作抗心律失常药物。它们特别适用于心律失常是冠状动脉狭窄的后果的情况,如心绞痛或急性心肌梗死。
