Complete biosynthesis of psychedelic tryptamines from three kingdoms in plants

Science Advances April 1, 2026 Paula Berman, Janka Höfer, Herschel Mehlman et al. 1 citation

-dimethyltryptamine (DMT) biosynthetic pathway in hallucinogenic plant species traditionally used in shamanic rituals for spiritual healing. Leveraging the similarities in their chemical structures, we reconstructed in one plant assay the full biosynthetic pathways of five renowned natural psychedelics; psilocin and psilocybin found in mushrooms, DMT from plants, and bufotenin and 5-methoxy-DMT...

Comprehensive analysis of 42 psilocybin-producing fungal strains reveals metabolite diversity and species-specific clusters.

Scientific Reports April 22, 2025 Jonathan Cohen, Liron Sulimani, Shiri Procaccia et al. 4 citations

Psilocybin-producing fungi have garnered attention due to accumulating evidence regarding the therapeutic potential of their principal component psilocybin. This diverse group of fungi harbors a wealth of less-studied metabolites, however, thus far most research has addressed them as a cohesive group. By optimizing an approach for extraction and analysis, we examined the metabolomes of 42...

A prospective ecological momentary assessment study of an ayahuasca retreat: exploring the salutary impact of acute psychedelic experiences on subacute affect and mindfulness skills in daily life

Psychopharmacology January 18, 2025 Sharon R. Sznitman, Yoel A Behar, Sheila Daniela Dicker-Oren et al. 3 citations

Abstract Rationale To examine the acute effects of ayahuasca use and their relationship to sub-acute changes in affect and mindfulness in a non-clinical sample, addressing the need for a better understanding of ayahuasca’s immediate and short-term impacts as interest in its use grows. Objectives Using prospective ecological assessment, this study investigates how ayahuasca used at a 4-day...
