Metabolite markers for three synthetic tryptamines N‐ethyl‐N‐propyltryptamine, 4‐hydroxy‐N‐ethyl‐N‐propyltryptamine, and 5‐methoxy‐N‐ethyl‐N‐propyltryptamine

Drug Testing and Analysis March 9, 2024 Marianne Skov-Skov Bergh, Inger Lise Bogen, Katharina Elisabeth Grafinger et al. 2 citations

N-Ethyl-N-propyltryptamine (EPT), 4-hydroxy-N-ethyl-N-propyltryptamine (4-OH-EPT), and 5-methoxy-N-ethyl-N-propyltryptamine (5-MeO-EPT) are new psychoactive substances classified as tryptamines, sold online. Many tryptamines metabolize rapidly, and identifying the appropriate metabolites to reveal intake is essential. While the metabolism of 4-OH-EPT and 5-MeO-EPT are not previously described,...

Psilocin glucuronide in whole blood: a stable and useful biomarker of psilocybin intake

Journal of Analytical Toxicology February 19, 2026 Marianne Skov-Skov Bergh, Inger Lise Bogen, Merete Vevelstad et al.

Detecting psilocybin use is challenging because it rapidly converts to its psychoactive metabolite psilocin, and both compounds are unstable in blood. Bufotenin, a structural isomer of psilocin, may exhibit comparable instability in blood. For reliable detection, we developed and validated an LC-MS/MS method to simultaneously quantify psilocin, bufotenin, and their metabolites, psilocin...
