4-Hydroxy-N,N-diisopropyltryptammonium hydrofumarate: Crystal Structure of a Synthetic Psychedelic

mycolabadmin

Scientists have determined the three-dimensional crystal structure of 4-HO-DiPT, a synthetic compound related to psilocin found in magic mushrooms. This is the first crystal structure of this specific compound and provides important structural information for understanding how it works. A related version of this compound is currently being tested in clinical trials for treating postpartum depression and other mood disorders.

Researchers determined the precise chemical structure of a synthetic compound related to psilocybin (the active ingredient in psychedelic mushrooms) using X-ray crystallography. The compound, 4-AcO-EPT, is designed to be converted in the body to a psychoactive substance with potential therapeutic benefits for depression and anxiety. The study resolved conflicting reports about the compound’s exact composition and molecular arrangement, showing it exists as a specific combination of three molecular components. This work demonstrates why chemists need to study actual crystal structures rather than relying solely on chemical calculations.

The glycolipid flocculosin-A from the fungus Anthracocystis flocculosa, or how to deal with cotton-wool-like crystals

mycolabadmin

Scientists successfully determined the three-dimensional structure of flocculosin-A, a powerful antifungal compound produced by a fungus called Anthracocystis flocculosa. The main challenge was that the compound naturally forms very thin, needle-like crystals unsuitable for analysis. By using a special cooling and heating cycle, researchers were able to grow better crystals and use X-ray diffraction to reveal the compound’s complete molecular structure, which contains a sugar backbone connected to two fatty acid chains with specific arrangements.
