A tablet sold under the brand name Party Duck and an unlabeled powder were analyzed with nuclear magnetic resonance spectroscopy, gas chromatography/mass spectrometry, and liquid chromatography/mass spectrometry. Both products contained 4-hydroxy-N-methyl-N-ethyltryptamine (4-HO-MET), a synthetic psychedelic similar to psilocin. The tablets held an average of 2.82 or 1.45 mg of 4-HO-MET per tablet, and the powder qualitatively contained the same compound. These results show that 4-HO-MET is present in commercially available products and underscore the need for rigorous analytical methods to monitor tryptamine derivatives in unregulated markets.
The Amanita muscaria mushroom contains alkaloids such as muscazone, muscarine, ibotenic acid, and muscimol, with the latter two acting as potent GABA agonists. Muscimol has served as a template for designing GABA agonists that do not affect GABA transaminase or GABA uptake. Analogs like THIP, THPO, iso-THIP, iso-THAZ, and 4-PIOL interact with GABA receptors differently. Conflicting opinions on the neuroprotective role of muscimol analogs against neurodegenerative diseases and their potential in treating cerebral ischemia and other health conditions motivate this review.
