Salsolidine, also known as 6,7-dimethylsalsolinol, O-methylsalsoline, or norcarnegine, is a tetrahydroisoquinoline alkaloid found in various cactus species.^[1]^[2] It is pharmacologically active.^[1] Salsolidine has been found to act as a weak but relatively potent monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) ((R)-enantiomer K_i = 6 μM), among other actions.^[1]^[3]
