Description and Uses
Chromanol 293B is a blocker of slowly activating delayed-rectifier K+ current (IKs) with an IC50 value of 6.89 μM in Xenopus oocytes expressing rat IKs channels. It is selective, having no activity at rat Kv1.1 or Kir2.1 channels at a concentration of 30 μM. Chromanol 293B increases the rate and extent of IKs in guinea pig ventricular cells in a dose-dependent manner. It also inhibits cystic fibrosis transmembrane conductance regulator (CTFR) Cl- currents (ICTFR) with an IC50 value of 19 μM in Xenopus oocytes expressing human CTFR.
Chromanol 293B has been used in the inhibition of calcium and cyclic adenosine monophosphate (cAMP)-activated potassium channels in human epithelial cell lines. Chromanol 293B has been used in patch-clamp electrophysiology studies in cardiomyocytes.
