Biological Activity

[Description]:

Cesium chloride is a blocker of potassium channel. Cesium chloride prevents the decrease of Na+ transport produced by Alloxan[1][2]. Cesium chloride has induced cardiac arrhythmias, including torsade de pointes in animal models[3].

Signaling Pathways >> Membrane Transporter/Ion Channel >> Potassium Channel

[In Vitro]

Cesium chloride (CsCl) decreases the increment of membrane potential, the elevation of intracellular calcium and the upregulation of NOS, ET-1 and VEGF expressions, which are induced by Acrolein[3].

[In Vivo]

Cesium Chloride (12 mg/100 g body weight, daily for 30 days; i.p.; male Wistar rats- BOO model) could significantly weaken the effect of XJT (traditional Chinese medicine) on not only the expression of these potassium channels but also the bladder weight, urodynamics, and oxidative stress[1].
