PD-118057

Research use only, not for human use.

A potent, selective hERG potassium channel (Kv11.1) activator that increases peak tail hERG current of 111.1% at 10 uM in HEK293 cells.

A potent, selective hERG potassium channel (Kv11.1) activator that increases peak tail hERG current of 111.1% at 10 uM in HEK293 cells; does not ot affect the voltage dependence and kinetics of gating parameters, and open conformation of the channel, also shows no major effect on I(Na), I(Ca,L), I(K1), and I(Ks); shortens the action potential duration and QT interval in arterially perfused rabbit ventricular wedge preparation, prevents action potential duration and QT prolongation caused by dofetilide at 3 uM.Heart Arrhythmia Discontinued.

PD-118057 (3 μM and 10 μM) specifically increases hERG current and inhibits action potential duration in guinea pig ventricular muscle in acute isolation of guinea pig cardiomyocytes.PD-118057 (10 μM) reverses the current inhibition induced by Dof and Mox without changing the "hump" shape of IKr current recorded by action potential clamp, and only slightly increases the peak value of the suppressed current.
