d-Deprenyl, also known as ordextro-N-propargyl-N-methylamphetamine, is anMAO-Binhibitor that metabolizes intod-amphetamine andd-methamphetamine and is therefore also anorepinephrine–dopamine releasing agent.[1][2][3][4][5] It is one of the twoenantiomers ofdeprenyl and is the opposite enantiomer ofl-deprenyl (selegiline).
l-Deprenyl, also an MAO-B inhibitor, metabolizes tol-amphetamine andl-methamphetamine, which are bothnorepinephrine releasing agents. In contrast,d-deprenyl additionally hasdopaminergic effects and has been found to bereinforcing in scientific research, whereasl-deprenyl is not known to have any appreciable psychological reinforcement.[6][7]
In addition to its actions as an MAO-B inhibitor and NDRA,d-deprenyl has been found to bind with highaffinity tosigma receptors (Ki = 79–1,800 nM) similarly to various other amphetamine derivatives.[8][9][10][11][12] Itsl-isomer, selegiline, binds with several-fold lower affinity in comparison.[8]
