Development and validation of an analytical method for the determination of select 4-position ring-substituted tryptamines in plasma by liquid chromatography–tandem mass spectrometry

Journal of Analytical Toxicology May 26, 2025 Malik Schoffner, Vamshikrishna Reddy Sammeta, Marilyn Naeem et al. 2 citations

Abstract 4-Phosporyloxy-N, N-dimethyltryptamine (psilocybin) is a psychedelic tryptamine found in certain mushroom species that has shown efficacy in the treatment of various psychiatric disorders. In conjunction with the renewed interest in therapeutic effects of psychedelics, there has been an increase in psilocybin-like designer tryptamines appearing in non-medical drug markets. The present...

Structure–Activity Relationships for Psilocybin, Baeocystin, Aeruginascin, and Related Analogues to Produce Pharmacological Effects in Mice

ACS Pharmacology & Translational Science November 2, 2022 Eline Pottie, Marilyn Naeem, Vamshikrishna Reddy Sammeta et al. 91 citations

4-Phosphoryloxy-N,N-dimethyltryptamine (psilocybin) is a naturally occurring tertiary amine found in many mushroom species. Psilocybin is a prodrug for 4-hydroxy-N,N-dimethyltryptamine (psilocin), which induces psychedelic effects via agonist activity at the serotonin (5-HT) 2A receptor (5-HT2A). Several other 4-position ring-substituted tryptamines are present in psilocybin-containing...
