HMR 1556 is a chromanol-derived small molecule used as a pharmacological tool in cardiac electrophysiology. It potently inhibits the slowly activating delayed rectifier potassium current (IKs) with reported IC50 values of 10.5 nM in canine and 34 nM in guinea pig left ventricular myocytes. The compound is supplied at research-grade purity and is used to probe IKs-mediated currents and cardiac repolarization mechanisms.

  • Potent IKs inhibition, IC50 10.5 nM (canine) and 34 nM (guinea pig).
  • Selective for IKs with weaker activity on other cardiac currents at higher concentrations.
  • Suitable for electrophysiology and ion-channel assays.
  • Available in multiple small-scale pack sizes for research use.
  • High purity suitable for biochemical and cellular studies.
