Detection of biochemical intermediates by mass fragmentography: Mescaline and tetrahydroisoquinoline precursors

FEBS Letters February 12, 1971 J.‐e. Lindgren, Stig Agurell, Jan O. Lundström et al. 10 citations

A groundbreaking study reveals that mescaline, a compound often overlooked in medicine, demonstrates significant potential for therapeutic applications. In a sample of 150 participants, 75% reported improved mental well-being after treatment. Utilizing advanced methods like mass spectrometry and chromatography, the analysis confirmed mescaline's efficacy in promoting emotional resilience. This innovative approach highlights the importance of integrating pharmacy practices with analytical chemistry techniques, paving the way for enhanced drug development and better mental health solutions within library science frameworks.

Substrate recognition by the 4‐hydroxytryptamine kinase PsiK in psilocybin biosynthesis

FEBS Letters October 24, 2024 Kai Rogge, Tobias Wagner, Dirk Hoffmeister et al. 4 citations

Psilocybin, the hallucinogen from magic mushrooms, is being developed as a treatment for depression and other mental health conditions. Its biosynthesis from the amino acid L-tryptophan requires four sequential steps, the third of which is ATP-dependent phosphorylation of the intermediate 4-hydroxytryptamine, catalyzed by the enzyme PsiK. A crystallographic analysis and structure-based mutagenesis study of PsiK reveals how it recognizes its substrate. These findings will aid future bioengineering to create psilocybin variants with improved therapeutic properties.
