ANTHRANILIC ACID AMIDES WITH A HETEROARYLSULFONYL SIDE CHAIN, METHOD FOR THE PRODUCTION THEREOF, USE THEREOF AS A MEDICAMENT OR A DIAGNOSTIC AGENT AND PHARMACEUTICAL PREPARATIONS CONTAINING SAID COMPOUNDS

摘要

The invention relates to compounds of formula (I), wherein R(1) -R(7) have the meanings cited in the claims. Said compounds act upon the Kv1.5-potassium channel and inhibit a potassium flow in the atrium of the human heart, designated as an ultra-rapidly activating delayed rectifier. As a result, they are particularly suitable for use as novel antiarrhythmic active substances, especially in the treatment and prophylaxis of atrial arrhythmia, e.g. atrial fibrillation (AF) or atrial flutter.
