Use of acacetin and related compounds as potassium channel inhibitors

摘要

This invention provides a method for treating or preventing human atrial arrhythmia (fibrillation) using the leading flavone compound acacetin, and its derivatives and analogues that inhibit the ultra-rapidly-activating delayed rectifier potassium current (IKur or IKsus), transient outward potassium (Ito), and acetylcholine-activated potassium current (IK.ACh).
