Descrizione generale

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).

Applicazioni

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.

Azioni biochim/fisiol

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

Colonic crypts are the site of Cl- secretion. Basolateral K+ channels provide the driving force for luminal cystic fibrosis transmembrane regulator-mediated Cl- exit. Relevant colonic epithelial K+ channels are the intermediate conductance Ca2+-activated K(Ca)3.1 (SK4) channel and the cAMP-activated K(V)7.1
