Myosmine-d₄ is the deuterium labeled Myosmine. Myosmine, a specific tobacco alkaloid in nuts and nut products, has low affinity for a4b2 nicotinic acetylcholinergic receptors (nAChR) with a Ki of 3300 nM.

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.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
