Isoindolone derivatives, preparation process and intermediates of this process, their use as medicaments, and pharmaceutical compositions comprising them

摘要

The present invention relates to the novel isoindolone derivatives of the formula I in which R1 to R6 have the meanings stated in the claims. The inventive compounds are suitable as antiarrhythmic medicaments with a cardioprotective component for infarction prophylaxis and infarction treatment and for the treatment of angina pectoris. They also inhibit in a preventive manner the pathophysiological processes associated with the development of ischemia-induced damage, in particular in the triggering of ischemia-induced cardiac arrhythmias and of heart failure.
