- 22. Crystal Structure To treat a patient, we need to have the legal right to giving it! • A little primer on patent law and crystal structure 22
- 23. Psilocybin as Medicine and Patent • Psilocybin cannot be patented as a molecule • Therefore, patent on Composition of Matter • Compass Pathways was granted a patent for a crystalline form of psilocybin, Polymorph A. • This patent grants exclusive rights • But does it hold up? Do we care? 23 https://terpenesandtesting.com/crystallizing-the-relationship-between-patents-polymorphs-and-psilocybin/
- 24. Crystal Engineering • Three States of Matter: gas, liquid, or solid. • Solid: molecules scrambled or highly ordered structures (crystals) • Crystals: infinitely repeating patterns • Nature of the repeat pattern matters, “polymorphs” • Over half of all organic molecule crystals have at least two polymorphs • Each polymorph has unique properties 24
- 25. Unique Crystalline Forms of Psilocybin • Psilocybin is hydroscopic, (in this case, a trihydrate) • Hydrate A (below) contains water molecules • Depending on storage conditions psilocybin can gain or lose water molecules • Polymorph A’ unit cell is in the shape of rectangular prisms with 90° • Polymorph B is rhomboid-shaped prisms with roughly a 95° 25 Baertschi SW, Alsante KM, Reed RA. Pharmaceutical Stress Testing; CRC Press: Boca Raton, 2011.
- 26. What about the Compass Pathway Patent • Compass claims discovery of new crystalline form of psilocybin (Polymorph A) • X-ray crystallography shows distinct diffraction peak at 17.5˚ • New, undiscovered structure or • Mixture of 81% Polymorph A’, 19% Polymorph B, and small amounts of Hydrate A. 26 Acta Crystallogr C Struct Chem. 2022;78(Pt 1):36-55
- 27. Summary • Many psychedelic compounds, botanical and synthetic • Many medical applications • But current clinical trials are flawed • We don’t even know what is in psilocybin mushrooms • Delic Labs works on closing that knowledge gap with metabolomics • Crystal structure or psilocybin can affect medical properties • Crystal structures can be patented, but should they?

Editor's Notes
- These things might make some participants feel more welcome, but they also put them at risk of being touched when they are unable to give consent. The level of individualistic makes it difficult to know how much the reduction of depressive symptoms is due to the drug, and it also makes it difficult to pool the experiences of patients when they are each having such different experiences. In some cases, it has led to patients becoming overly dependent on their therapists and seeing them as a friend, which led to distress when the treatment suddenly ended.

- It is likely that Polymorph B showed up due to challenges in maintaining uniform heating and preventing microenvironments as a result of their large-scale production, which is easier to control on a smaller, lab scale. Further, since psilocybin is hygroscopic, a dried crystalline sample corresponding to Polymorph A would quickly absorb water, changing it back to Hydrate A. This calls into question the shelf stability of Compass’s crystalline psilocybin, and whether they would truly be selling a pure form of Polymorph A. Many of these concerns would need to be addressed going forward if Compass Pathways is to hold onto and defend the rigor of their patent. If Compass Pathways is unable to address these concerns, they are most likely to lose their patent preventing sole claim on the production of Polymorph A, keeping medical psilocybin in the public domain for research and commercial purposes. However, if their patent is granted, it could lead to monopolistic control over the production of medical psilocybin. How? Only one group can be granted a patent for a polymorph structure, and US Food and Drug Administration (FDA) approval often follows. If Polymorph A is granted approval as the first FDA–approved medical psilocybin, then Compass would be the sole supplier of medical psilocybin until other companies succeed in discovering a new structure, getting a patent, and FDA approval.
