“In vivo biosynthesis of N,N-dimethyltryptamine, 5-MeO-N,N-dimethyltryptamine, and bufotenine in E. coli”

Metabolic Engineering, 2023
N,N-dimethyltryptamine (DMT), 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and 5-hydroxy-N,N-dimethyltryptamine (bufotenine) are psychedelic tryptamines found naturally in both plants and animals and have shown clinical potential to help treat mental disorders, such as anxiety and depression.

Biosynthesis and turnover of N,N-dimethyltryptamine and 5-methoxy-N,N-dimethyltryptamine in Phalaris tuberosa

Phytochemistry, 1972
Abstract The biosynthesis and turnover of N , N -dimethyltryptamine and 5-methoxy- N , N -dimethyltryptamine have been studied in the pasture grass Phalaris tuberosa by a combination of feeding and trapping experiments using radioisotopically labelled compounds. Their turnover has been demonstrated by feeding tryptophan and tryptamine.

Dimethyltryptamine levels in blood of schizophrenic patients and control subjects

Psychopharmacology, 1976
A gas chromatographic-mass spectrometric determination of blood N,N-dimethyltryptamine in normal controls and schizophrenic patients was carried out with a sensitivity limit of 0.05 ng/ml whole blood. Although the results appear to suggest that the mean DMT level was higher in the total patient group, those patients with acute psychosis, female ...

Neural and subjective effects of inhaled N,N-dimethyltryptamine in natural settings

Journal of Psychopharmacology, 2021
Background: N,N-dimethyltryptamine is a short-acting psychedelic tryptamine found naturally in many plants and animals. Few studies to date have addressed the neural and psychological effects of N,N-dimethyltryptamine alone, either administered ...
