N-Methylphenethylamine (NMPEA), a positional isomer of amphetamine, is a naturally occurring trace amine neuromodulator in humans that is derived from the trace amine, phenethylamine (PEA). It has been detected (< 1 μg/24 hrs.) in human urine and is produced by phenylethanolamine N-methyltransferase with phenethylamine as a substrate. PEA and NMPEA are both alkaloids that are found in a number of different plant species as well. Some Acacia species, such as A. rigidula, contain remarkably high levels of NMPEA (~2300–5300 ppm). NMPEA is also present at low concentrations (< 10 ppm) in a wide range of foodstuffs.
