Abstract Psilocybin ( 1 ) is the major alkaloid found in psychedelic mushrooms and acts as a prodrug to psilocin ( 2 , 4‐hydroxy‐ N , N ‐dimethyltryptamine), a potent psychedelic that exerts remarkable alteration of human consciousness. In contrast, the positional isomer bufotenin ( 7 , 5‐hydroxy‐ N , N ‐dimethyltryptamine) differs significantly in its reported pharmacology. A series of...

Abstract Psilocin ( 1 ) is the dephosphorylated and psychotropic metabolite of the mushroom natural product psilocybin. Oxidation of the phenolic hydroxy group at the C‐4 position of 1 results in formation of oligomeric indoloquinoid chromophores responsible for the iconic blueing of bruised psilocybin‐producing mushrooms. Based on previous NMR experiments, the hypothesis included that the...

Abstract Psychotropic fungi of the genus Psilocybe , colloquially referred to as „magic mushrooms”, are best known for their l ‐tryptophan‐derived major natural product, psilocybin. Yet, recent research has revealed a more diverse secondary metabolism that originates from this amino acid. In this minireview, the focus is laid on l ‐tryptophan and the various Psilocybe natural products and their...

Abstract Psilocybin, the principal indole alkaloid of Psilocybe mushrooms, is currently undergoing clinical trials as a medication against treatment‐resistant depression and major depressive disorder. The psilocybin supply for pharmaceutical purposes is met by synthetic chemistry. We replaced the problematic phosphorylation step during synthesis with the mushroom kinase PsiK. This enzyme was...

Abstract Upon injury, psychotropic psilocybin‐producing mushrooms instantly develop an intense blue color, the chemical basis and mode of formation of which has remained elusive. We report two enzymes from Psilocybe cubensis that carry out a two‐step cascade to prepare psilocybin for oxidative oligomerization that leads to blue products. The phosphatase PsiP removes the 4‐ O ‐phosphate group to...

Abstract The fungal genus Psilocybe and other genera comprise numerous mushroom species that biosynthesize psilocybin (4‐phosphoryloxy‐ N , N ‐dimethyltryptamine). It represents the prodrug to its dephosphorylated psychotropic analogue, psilocin. The colloquial term “magic mushrooms” for these fungi alludes to their hallucinogenic effects and to their use as recreational drugs. However,...

We report the identification of ω-N-methyl-4-hydroxytryptamine (norpsilocin, 1) from the carpophores of the hallucinogenic mushroom Psilocybe cubensis. The structure was elucidated by 1D and 2D NMR spectroscopy and high-resolution mass spectrometry. Norpsilocin has not previously been reported as a natural product. It likely represents the actual psychotropic agent liberated from its...
