DL-Phenylalanine-d₅ hydrochloride  (Synonyms: 2-Amino-3-phenylpropionic acid-d₅ hydrochloride)

DL-Phenylalanine-d₅ (hydrochloride) is the deuterium labeled DL-Phenylalanine hydrochloride. L-Phenylalanine hydrochloride is an essential amino acid isolated from Escherichia coli. L-Phenylalanine hydrochloride is a α2δ subunit of voltage-dependent Ca+ channels antagonist with a Ki of 980 nM. L-phenylalanine hydrochloride is a competitive antagonist for the glycine- and glutamate-binding sites of N-methyl-D-aspartate receptors (NMDARs) (KB of 573 μM ) and non-NMDARs, respectively. L-Phenylalanine hydrochloride is widely used in the production of food flavors and pharmaceuticals[1][2][3][4].

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].
