4 Methylphenethylamine

4-Methylphenethylamine (4MPEA), also known as para-methylphenethylamine, is an organic compound with the chemical formula of C₉H₁₃N. 4MPEA is a human trace amine associated receptor 1 (TAAR1) agonist, a property which it shares with its monomethylated phenethylamine isomers, such as amphetamine (α-methylphenethylamine), β-methylphenethylamine, and N-methylphenethylamine (a trace amine). 4MPEA also appears to inhibit the human cytochrome P450 enzymes CYP1A2 and CYP2A6, based upon the published literature.
