Chemoenzymatic Synthesis of 5-Methylpsilocybin: A Tryptamine with Potential Psychedelic Activity

February 21, 2022 / Mushrooms / Psilocybin, Papers, Pharmacology & Chemistry / Leave a Comment / By / , , , ,

Abstract

A novel analogue of psilocybin was produced by hybrid chemoenzymatic synthesis in sufficient quantity to enable bioassay. Utilizing purified 4-hydroxytryptamine kinase from Psilocybe cubensis, chemically synthesized 5-methylpsilocin (2) was enzymatically phosphorylated to provide 5-methylpsilocybin (1). The zwitterionic product was isolated from the enzymatic step with high purity utilizing a solvent-antisolvent precipitation approach. Subsequently, 1 was tested for psychedelic-like activity using the mouse head-twitch response assay, which indicated activity that was more potent than the psychedelic dimethyltryptamine, but less potent than that of psilocybin.

Psilocybin Therapeutic Research: The Present and Future Paradigm

Abstract

Psilocybin, an active component in “magic mushroom”, may have the potential to meet the therapeutic needs for a number of indications without the addictiveness and overdose risk of other mind-altering drugs, such as cocaine, heroin, alcohol, methamphetamine, and so forth. The need for new therapies is urgent because addiction, overdose, and suicide deaths have risen throughout the United States and around the world. Anecdotal and contemporary pharmacological reports have provided some indication about the therapeutic use of psilocybin for the treatment of mental health disorders such as major depressive disorder and addiction disorders. In this Viewpoint, I summarize the current state of psilocybin therapeutic research and attempt to provide some insight into future directions on which the scientific community may wish to focus.
