摘要

Benzoylguanidines of the formula I IMAGE where R(1) is hydrogen, Hal, -NO2, -C IDENTICAL N, -CF3, R(4)-SOm or R(5)R(6)N-SO2-, R(4) and R(5) being alk(en)yl, or CF3, with R(5) also having the meaning of H, R(2) is heteroaryl, or -SR(10), -OR(10), -NR(10)R(11) or -CR(10)R(11)R(12); where R(10) is -CaH2a-heteroaryl, R(11) and R(12) are defined as R(10) or are hydrogen or alkyl, R(3) is defined as R(1) or is alkyl or -X-R(13), where X is oxygen, S or NR(14), and R(13) is H or (cyclo)alkyl, are described. They are obtained from a compound II IMAGE by reaction with guanidine. The compounds are outstandingly suitable for use as anti-arrhythmic drugs (medicaments, pharmaceuticals) having a cardioprotective component for the prophylaxis and treatment of infarction and also for the treatment of angina pectoris, the compounds also inhibiting or strongly reducing, in a preventive manner, the pathophysiological processes associated with the occurrence of ischemically-induced damage, in particular in association with the triggering of ischemically-induced cardiac arrhythmias.
