Application

NS 1619 has been used as calcium-activated potassium channels (BK)-activator: to study its vaso-relaxing effects on the thoracic aortic rings from mice, to evaluate its effects on the sarco-/endoplasmic reticulum Ca2+-ATPase (SERCA) activity from skeletal muscles, to determine its effects on the expression of caveolin-1 protein in mice brain tumor microvascular endothelial cells

Biochem/physiol Actions

NS 1619 is a selective large conductance Ca2+-activated K+-channel activator. The compound is known for its vasodilating and anti-proliferative properties. It is studied that NS 1619 can protect cardiac muscle against ischemia and reperfusion injury.
NS-1619 can promote the formation of mitochondrial reactive oxygen species (ROS) in cardiac myocytes. It enhances the formation of ROS in cultured brain slices. NS-1619 has the ability to enhance HO-1 activity in wild-type (WT) animals.

Activators and blockers of specific ion channels are important pharmacological tools for characterizing ion channels and their influence on cell function. The large-conductance Ca(2+)-dependent K+ channel (BK channel) is blocked by peptides such as charybdotoxin and iberiotoxin, but no selective

Large conductance voltage- and Ca(2+)-activated K(+) (BK) channels are important in regulating detrusor smooth muscle (DSM) function. Here, we examined systematically how the BK channel pharmacological activation modulates DSM contractility. NS1619, a potent BK channel activator, was utilized as a
