Scientists created new forms of a drug found in 'magic mushrooms' that can treat depression without causing intense hallucinations. This could lead to safer and more practical treatment strategies.

Mushrooms have been a topic of interest for scientists studying treatments for conditions like depression, anxiety, and some neurodegenerative diseases. However, the intense hallucinogenic effects associated with these compounds may limit their use in medicine. Researchers created modified forms of psilocin, the active compound produced when psilocybin is processed in the body. These new molecules maintained their biological activity while triggering fewer hallucinogenic-like effects than pharmaceutical grade psilocybin.

Targeting serotonin pathways in brain disorders can help treat mood disorders and neurodegenerative conditions like Alzheimer's disease. Researchers have spent decades exploring psychedelics because of their influence on serotonin signaling in the brain. However, the hallucinations often associated with these compounds can make some patients hesitant to consider them as treatments.

To address this challenge, a research team designed five chemical variants of psilocin. These compounds were engineered to release the active molecule into the brain more slowly and steadily, potentially reducing hallucinogenic effects while preserving therapeutic activity. The scientists evaluated the five compounds in laboratory experiments using human plasma samples and conditions that simulate gastrointestinal absorption.

The most promising candidate, known as 4e, demonstrated strong stability during absorption and produced a gradual release of psilocin. At the same time, 4e continued to activate key serotonin receptors at levels similar to psilocin. Researchers then compared equivalent doses of 4e and pharmaceutical grade psilocybin in mice.

The substances were given orally, and the team tracked how much psilocin reached the bloodstream and brain over a 48 hour period. In animals treated with 4e, the compound crossed the blood-brain barrier efficiently and produced a lower but longer lasting level of psilocin in the brain compared with psilocybin.

Behavioral observations revealed another important difference. Mice receiving 4e showed significantly fewer head twitches, which scientists use as a reliable indicator of psychedelic-like activity in rodents, than mice treated with psilocybin.
