Amiodarone-d₄ hydrochloride 

Amiodarone-d₄ (hydrochloride) is the deuterium labeled Amiodarone hydrochloride. Amiodarone hydrochloride, a benzofuran-based Class III antiarrhythmic agent, inhibits WT outwardIhERG tails with an IC50 of ∼45 nM[1]. Amiodarone hydrochloride induces cell proliferation and myofibroblast differentiation via ERK1/2 and p38 MAPK signaling in fibroblasts[2]. Amiodarone hydrochloride can be used in the research of both supraventricular and ventricular arrhythmias[1].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
