D-Phenylalanine (DPA, D-Phe), sold under the brand names Deprenon, Sabiben, and Sabiden, is an enantiomer of phenylalanine which is described as an antidepressant and is marketed as a prescription drug for medical use in Argentina.

[1][2] The medication has been marketed since at least the 1970s[3] and continued to be available by the 2000s.

[1] D-Phenylalanine has been found to act as an enkephalinase inhibitor, an inhibitor of enkephalinase enzymes that break down endogenous opioid peptides called enkephalins.

[4][5] It has been found to produce anti-inflammatory, analgesic, and anti-craving effects in animal studies.
