Overview

Chromanol 293B is a selective blocker of the slow delayed rectifier K+ current (IKs) with IC50 of 1-10 μM and a weak inhibitor of KATP channel. Chromanol 293B also blocks the CFTR chloride current with an IC50 of 19 μM.

Purpose：

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.
