Sematilide hydrochloride BiologicalActivity

Description	Sematilide hydrochloride (CK-1752 hydrochloride) is a selective IKr channel blocker. Sematilide causes a concentration-dependent inhibition of the delayed rectifier K+ current (IC50=25 μM). Sematilide is a class III antiarrhythmic agent[1].
Related Catalog	Research Areas >>Cardiovascular DiseaseSignaling Pathways >>Membrane Transporter/Ion Channel >>Potassium Channel
Target	IC50: 25 μM (K+ current)[1]
In Vitro	Application of 10, 30, 100 and 300 μM Sematilide causes a concentration-dependent inhibition of the delayed rectifier K+ current (IC50=25 μM)[1].
In Vivo	Sematilide (0.3-1.0 mg/kg, intravenously i.v.) is effective in a canine model of arrhythmia[2]. Animal Model: Mongrel dogs of either sex (10-18 kg body weight)[2] Dosage: 0.3, 1, 3, and 10 mg/kg Administration: I.v. infusions Result: Demonstrated antiarrhythmic effects at 0.3 and 3.0 mg/kg.
