Background:

HMR 1556, a chromanol derivative, is a IKs blocker with IC50s of 10.5 nM and 34 nM in canine and guinea pig left ventricular myocytes, respectively[1][2]. IC50: 10.5 nM (IKs in canine left ventricular myocytes), 34 nM (IKs in guinea pig left ventricular myocytes)[1]

HMR 1556 inhibits Ito, ICa,L and IKr with IC50s of 33.9 μM, 27.5 μM, 12.6 μM in canine left ventricular myocytes, respectively[1].
