Bioactivation and Metabolism of Amino Acid MDMA Prodrugs in Zebrafish Embryos, Human Liver S9, Whole Blood, and Microdosed Human Urine

Drug Testing and Analysis March 15, 2026 Simon K. Wellenberg, Lea Wagmann, Matthias D. Kroesen et al.

ABSTRACT 3,4‐Methylenedioxymethamphetamine (MDMA) remains unapproved for therapeutic use despite the promising results of MDMA‐assisted psychotherapy. There is a need to better understand the safety, pharmacokinetics, and toxicology of possible MDMA‐based prodrugs. Like lisdexamfetamine, amino acid prodrugs of MDMA may enable more controlled systemic exposure, but their metabolic activation...

Toxicometabolomics Characterization of Two N1-Sulfonated Dimethyltryptamine Derivatives in Zebrafish Larvae and Human Liver S9 Fractions Using Liquid Chromatography-High-Resolution Mass Spectrometry.

Metabolites February 14, 2026 Prajwal Punnamraju, Sascha K. Manier, Selina Hemmer et al.

Introduction: The availability of toxicokinetic data is critical for detecting and monitoring the intake of psychoactive substances. Timely characterization of novel psychoactive substances (NPS) is particularly important to assess their abuse potential and inform public health responses. Methods: Toxicometabolomics offers a powerful approach to characterize xenobiotic metabolism through...

Metabolism and cytotoxicity studies of the two hallucinogens 1cP-LSD and 4-AcO-DET in human liver and zebrafish larvae models using LC-HRMS/MS and a high-content screening assay.

Journal of Pharmaceutical and Biomedical Analysis August 1, 2024 Tanja M Gampfer, Victoria Schütz, Philip Schippers et al. 11 citations

The continuous emergence of new psychoactive substances (NPS) attracted a great deal of attention within recent years. Lately, the two hallucinogenic NPS 1cP-LSD and 4-AcO-DET have appeared on the global market. Knowledge about their metabolism to identify potential metabolic targets for analysis and their cytotoxic properties is lacking. The aim of this work was thus to study their in vitro...
