Different biosynthetic pathways for the active ingredient, the tryptamine psilocybin, have evolved independently at least twice in the fungal lineage. Its physiological function in the mushroom is not yet fully understood. One theory is that oligomers with a tannin-like structure, formed when the fungal tissue is damaged, serve as a defense against herbivores. Due to its psychedelic effects, its use as a recreational drug carries the risk of psychotic states and panic attacks if the dosage is uncontrolled. The risk of addiction is considered relatively low. As a serotonin agonist, psilocin increases neuronal plasticity. Therefore, the potential of psilocybin-assisted psychotherapy is currently investigated in clinical trials.</p>\u0000 </div>","PeriodicalId":9911,"journal":{"name":"Chemie in Unserer Zeit","volume":"60 3","pages":"132-139"},"PeriodicalIF":0.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the shape memory polymers, thermoplastic polyurethanes are probably the best studied today. Thermoplastic polyurethanes can be synthesized with a wide variety of properties. The control of their material behavior when the temperature changes (thermoresponsiveness) is ensured by a thermomechanical treatment also known as programming. The application examples are diverse and include aerospace technologies, security labels for plagiarism protection and dental splints as well as easily transportable pieces of furniture. The methods developed a few years ago for programming two-way shape memory effects have produced the first generations of actuators and made initial contributions to opening up the research field of programmable materials. The approach to programming system functionalities enables a paradigm shift in product design, as it aims to simplify technological complexity - from now on, the functionality is in the material and therefore in the component!
