Nicardipine-d₄ hydrochloride  (Synonyms: YC-93-d₄)

Nicardipine-d₄ hydrochloride is deuterated labeled Nicardipine hydrochloride (HY-12515A). Nicardipine hydrochloride (YC-93) is a calcium channel blocker with an IC₅₀ of 1 μM for blocking cardiac calcium channels. Nicardipine hydrochloride acts as an agent for chronic stable angina and for controlling blood pressure^[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].
Nicardipine (0.1-10 μM; 24-48 h) reduces viability and proliferation of vascular smooth muscle cells (VSMCs) and inhibits their ability to migrate^[3].
