The psychotropically active compounds of the Mexican hallucinogenic fungus Psilocybe mexicana were isolated and crystallized. Two new substances, named psilocybin and psilocin, are present in the fruit bodies, artificially cultivated mycelium, and sclerotia. The dried mushroom contains 0.2 to 0.4 percent psilocybin; psilocin is present at most in trace amounts only.

Psilocybin, a hallucinogen found in certain mushrooms, has shown promise in treating anxiety and depression. In a study with 100 participants, 60% reported significant reductions in anxiety symptoms after a single dose. The chemical synthesis of psilocybin mimics natural alkaloids, enhancing its therapeutic potential. Participants experienced a profound shift in perspective, with 75% noting improved emotional well-being. These findings highlight the efficacy of psychedelics like psilocybin in mental health treatment, suggesting a transformative approach to therapy.

Modifications to the molecular structure of the natural psychedelic compounds psilocybin and psilocin were systematically explored to clarify how structure relates to psychotropic activity. The synthesis and properties of several derivatives are described, including position isomers with a phosphoryloxy or hydroxy group at positions 5, 6, or 7, the four isomeric hydroxygramines, and psilocin variants altered at the ω-nitrogen, indole nitrogen, or side-chain (e.g., additional methylene, methyl substitution, or hydroxylation). Also reported are phosphoric acid esters of some derivatives, esters with organic carbonic and sulfonic acids, methylcarbaminic and sulfuric acid esters, and position isomers with the dimethylaminoethyl side-chain at position 1 or 2.
