Potent and selective Iks
channel blocker (IC50
values are 10.5 and 34 nM in canine and guinea pig ventricular myocytes respectively). Selectively inhibits IKs
currents over IKr
and L-type Ca2+
channel currents. Also has little or no effect on Kv
2.1 and HCN2 channel currents. Potentiates E-4031
-induced arrhythmias in vivo
