HY-B0432

Propafenone 2 Publications Verification SA-79	Sodium Channel Adrenergic Receptor Potassium Channel	Cardiovascular Disease Cancer
Propafenone (SA-79), a *sodium-channel* blocker, acts an antiarrhythmic agent. Propafenone also has high affinity for the β receptor (IC₅₀=32 nM) . Propafenone blocks the transient outward current (Ito) and the sustained delayed rectifier K current (Isus) with IC₅₀ values of 4.9 μm and 8.6 μm, respectively . Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction and induce apoptosis .

HY-N0663

Talatisamine	Mitochondrial Metabolism Cyclophilin Potassium Channel	Cardiovascular Disease Neurological Disease Inflammation/Immunology
Talatisamine is an orally active cyclophilin D activator isolated from the roots of Aconitum carmichaeli Debx. Talatisamine exerts biological functions by activating cyclophilin D, inhibiting Ca ²⁺-dependent opening of the mitochondrial permeability transition pore (mPTP) (IC₅₀=78 μM), and blocking delayed *rectifier* K ⁺ channels (IC₅₀=146 μM). Talatisamine possesses both antioxidant and membrane-stabilizing properties, effectively inhibits lipid peroxidation and protects mitochondrial membrane function. Talatisamine exhibits multiple activities including antiarrhythmic, hypotensive, anti-inflammatory, anticancer and neuroprotective effects. Talatisamine finds applications in the research of ischemic diseases, rheumatoid arthritis, inflammation-related diseases and Alzheimer's disease .

HY-108575

Chromanol 293B 1 Publications Verification	Potassium Channel CFTR	Cardiovascular Disease
Chromanol 293B is a selective blocker of the *slow delayed* rectifier K ⁺ current (IKs) with IC₅₀** of 1-10 μM and a weak inhibitor of KATP channel. Chromanol 293B also blocks the CFTR chloride current with an IC₅₀ of 19 μM .

HY-101436A

Sematilide hydrochloride CK-1752 hydrochloride	Potassium Channel	Cardiovascular Disease
Sematilide hydrochloride (CK-1752 hydrochloride) is a selective I_Kr channel blocker. Sematilide causes a concentration-dependent inhibition of the delayed rectifier K ⁺ current (IC₅₀=25 μM). Sematilide is a class III antiarrhythmic agent .

HY-106855

Almokalant H 234/09	Potassium Channel	Cardiovascular Disease
Almokalant is a class III antiarrhythmic agent, acts as a potassium channel blocker, and inhibits a specific component (Ikr) of the time-dependent delayed rectifier K ⁺ current.

HY-101436

Sematilide CK-1752	Potassium Channel	Cardiovascular Disease
Sematilide (CK-1752) is a selective I_Kr channel blocker. Sematilide causes a concentration-dependent inhibition of the delayed rectifier K ⁺ current (IC₅₀=25 μM). Sematilide is a class III antiarrhythmic agent .

HY-101436AR

Sematilide hydrochloride (Standard) CK-1752 hydrochloride (Standard)	Reference Standards Potassium Channel	Cardiovascular Disease
Sematilide (hydrochloride) (Standard) is the analytical standard of Sematilide (hydrochloride). This product is intended for research and analytical applications. 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 .

HY-118148

UK-66914	Potassium Channel	Cardiovascular Disease
UK-66914, is a class III antiarrhythmic agent that specifically acts on the delayed rectifier potassium current (I_K). UK-66914 is designed to prolong action potential duration (APD) and increase cardiac refractory period, thereby potentially terminating the reentry mechanism in arrhythmias without affecting the serious side effects of antiarrhythmic drugs associated with other ion channels such as Na+ and Ca2+ currents .
