Levomilnacipran-d₅ hydrochloride  (Synonyms: (1S,2R)-Milnacipran-d₅ hydrochloride; F-2695-d₅ hydrochloride)

Levomilnacipran-d5 ((1S,2R)-Milnacipran-d5) hydrochloride is deuterium labeled Levomilnacipran hydrochloride (HY-B0168B). Levomilnacipran ((1S,2R)-Milnacipran) hydrochloride is the enantiomer of Milnacipran (HY-B0168) and a strong substrate of P-gp that can cross the blood-brain barrier. Levomilnacipran hydrochloride is a serotonin and norepinephrine reuptake inhibitor, with IC₅₀ values of 10.5 nM and 19.0 nM, and K_i values of 92.2 nM and 1.2 nM for human norepinephrine transporter (NET) and serotonin transporter (SERT), respectively. Levomilnacipran hydrochloride has antidepressant and anxiolytic activities. Levomilnacipran hydrochloride can be used for the research of depression^[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].
