摘要

Antiarrhythmic and Cardioprotective Substituted -1(2H)isoquinolines, process for their production, medicament containing them and their use for the production of a medicament for combating heart failures Described are guanidinocarbonyl isoquinolines I, IMG I with R(1) hydrogen, (amino)(cyclo)(aryl)alk(en)yl, (heteroaryl); R(2) hydrogen, halogen, alkyl, or Aryl; G IMG V I I X(2), X(3) and X(4) hydrogen, halogen, nitro, amino, alkyl, sulfonamide, (mono)(di)(lower alkyl)(amino), benzyloxy, hydroxy; X(1) hydrogen, oxygen, sulfur and NR(7)R(8), and their pharmaceutically acceptable salts; described is also the process for their preparation, their use as medicaments, and medicaments containing them for treating congestive heart failure, arrhythmic conditions as well as cardioprotective agents in mammals.
