Selective Kv1.5 Blockers: Development of (R)-1-(Methylsulfonylamino)-3-[2-(4-methoxyphenyl)ethyl]-4-(4-methoxyphenyl)-2-imidazolidinone (KVI-020/WYE-160020) as a Potential Treatment for Atrial Arrhythmia
摘要:
Atrial fibrillation is the most prevalent form of cardiac arrhythmia. Current treatments extend the atrial effective refractory period by nonselective blockade of cardiac ion channels. An alternative approach selectively targeting the Kv1.5 ion channel offers the opportunity for therapeutic benefit with decreased risk of adverse cardiovascular events. KVI-020 (4g) successfully demonstrated antiarrhythmic efficacy in a canine arrhythmia model, and these findings support its utility as an antiarrhythmic agent.
The present invention relates to 1-N-amino-2-imidazolidinones and derivatives thereof which are effective as Kv1.5 potassium channel inhibitors providing atrial-selective antiarrhythmic agents. The present invention further relates to compositions comprising said Kv1.5 potassium channel inhibitors, and to methods for treating cardiac arrhythmia.
