The invention relates to compounds according to Formula (I): or a pharmaceutically acceptable salt thereof, wherein m, n, R1, R2, R3, R4, R5, x and y are as defined herein. Compounds according to Formula (I) are pharmacologically effective as potassium channel inhibitors, in particular inhibitors of the acetylcholine operated inward rectifying potassium channel current (i.e. IKACh blockers), and are believed to be useful in the treatment of cardiac arrhythmias, in particular supraventricular tacharrhythmias, such as atrial fibrillation and atrial flutter.
该发明涉及按照公式(I)的化合物或其药用可接受的盐,其中m、n、R1、R2、R3、R4、R5、x和y如本文所定义。公式(I)的化合物在药理学上作为钾通道抑制剂具有药效,特别是乙酰胆碱激活的向内整流钾通道电流的抑制剂(即IKACh阻滞剂),并被认为在治疗心律失常方面有用,特别是在尤为心室上速心律失常,如心房颤动和心房扑动的治疗中。
