摘要：

Class III anti-arrhythmic drugs (e.g., dofetilide) prolong cardiac action potential duration (APD) by blocking the fast component of the delayed rectifier potassium current (I-Kr). The block of I-Kr can result in life threatening ventricular arrhythmias (i.e., torsades de pointes). Unlike I-Kr, the role of the slow component of the delayed rectifier potassium current (I-Ks) becomes significant only at faster heart rate. Therefore selective blockers Of I-Ks could prolong APD with a reduced propensity to cause proarrhythmic side effects. This report describes structure-activity relationships (SARs) of a series of I-Ks inhibitors derived from 6-alkoxytetralones with good in vitro activity (IC50 > 30 nM) and up to 40-fold I-Ks/I-Kr selectivity.
