Description

General description

Chromanol 293B enantiomer is a potent inhibitor of potassium channel protein (KvLQT1). In human atrial myocytes, chromanol 293B inhibits repolarization potassium currents. Chromanol 293B improves glucose-stimulated insulin secretion (GSIS) in pancreas by modulating potassium voltage-gated channel (KCNQ1).

Application

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.

Biochem/physiol Actions

Blocker of the slow delayed rectifier K⁺ current via KCNQ1 channels
