and I
Kur
, that could serve as targets for the treatment of cardiac arrhythmias especially atrial arrhythmias. The present invention also provide a method for treating or preventing conditions which respond to the inhibition of potassium channels or currents, such as cardiac arrhythmias and more especially atrial arrhythmias. The present invention further includes pharmaceutical formulations and a process of making a pharmaceutical composition comprising a compound of certain isoquinolinone or its pharmaceutically acceptable salts, hydrates, solvates, crystal forms, and stereoisomers thereof, and a pharmaceutically acceptable carrier.
本发明涉及某些异喹啉酮化合物及其作为电压依赖性钾通道或电流抑制剂的用途,如Kv1.5和IKur,可作为治疗心律失常特别是心房心律失常的靶点。本发明还提供了一种治疗或预防对钾通道或电流抑制作出反应的疾病的方法,如心律失常,尤其是心房心律失常。本发明还包括制药配方和制备含有某些异喹啉酮化合物或其药用可接受的盐、水合物、溶剂合物、晶型和立体异构体以及药用可接受载体的制药组合物的过程。
