A simple method for analysis of 5-methoxy-N,N-di-n-propyltryptamine (5-MeO-DPT) in urine has been developed using gas chromatography-mass spectrometry (GC-MS) with tetradecadeuterated 5-MeO-DPT as internal standard, which is useful for discrimination

To examine whether simple beta-carbolines induce parkinsonian-like symptoms in vivo via N-methylation, the simple beta-carbolines norharman (NH), 2-mono-N-methylated norharmanium cation (2-MeNH+), and 9-mono-N'-methylnorharman (9-MeNH) were systemati
