Recently, many lysergic acid diethylamide (LSD) analogs have emerged as designer drugs worldwide. In Japan, these compounds are distributed as paper sheet or tablet products and are available online. Even after these compounds were regulated, new compounds with modified structures continued to appear. In the present study, two LSD analogs were identified from tablet or paper sheet products. Gas...

Recently, numerous lysergic acid diethylamide (LSD) analogs have emerged as designer drugs globally. These compounds are mainly distributed as sheet products. In this study, two new LSD analogs were identified from sheet products. The structures of the compounds were determined by gas chromatography-mass spectrometry, liquid chromatography-photodiode array-mass spectrometry, liquid...

Recently, lysergic acid diethylamide (LSD) analogs have appeared worldwide as designer drugs. In this study, we identified a distributed LSD analog from a paper-sheet product. Gas chromatography-mass spectrometry (GC-MS), liquid chromatography-photodiode array-mass spectrometry (LC-PDA-MS), and liquid chromatography with hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) were used...

Many analogs of lysergic acid diethylamide (LSD) have recently appeared as designer drugs around the world. These compounds are mainly distributed as sheet products. In this study, we identified three more newly distributed LSD analogs from paper sheet products. The structures of the compounds were determined by gas chromatography-mass spectrometry (GC-MS), liquid chromatography-photodiode...

Arylcyclohexylamines are a category of substances to which the anesthetic ketamine belongs. The arylcyclohexylamines have been reported to act as antagonists of the N-methyl-d-aspartate (NMDA) receptor. An analog of ketamine, 2-(ethylamino)-2-(3-methoxyphenyl)-cyclohexanone (methoxetamine; MXE), has been controlled as a narcotic in Japan and overdoses of MXE have been reported to cause health...

A sensitive immunochemical method for identifying hallucinogenic mushrooms (magic mushrooms) is required for regulating their illicit use. We have previously generated a monoclonal antibody (mAb) that targets psilocin (Psi), the major psychoactive compound in hallucinogenic mushrooms, and developed an enzyme-linked immunosorbent assay (ELISA). However, this ELISA failed to achieve the expected...

Lysergic acid diethylamide (LSD) is a hallucinogen, synthesized from ergot alkaloid, and controlled as a narcotic in Japan. Recently, LSD derivatives have appeared as designer drugs, all over the world. In previous study, we reported identification and analysis of four LSD derivatives in four paper sheet products. In this study, we detected three additional LSD derivatives from three paper...

Development of rapid and reliable immunochemical methods for monitoring psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine; Pyb) and psilocin (dephosphorylated metabolite; Psi), the psychoactive compounds contained within hallucinogenic mushrooms (magic mushrooms), is desirable in order to identify these mushrooms and regulate their illicit use. Because no antibody was publicly available for...

To prevent the abuse of new psychoactive substances (NPS), a total of 2372 substances and two plants are controlled as "Designated Substances" in Japan as of September 2019. Although the distribution of these substances has decreased for the past three years, newly-emerged NPS are still being found. In this study, we detected four lysergic acid diethylamide (LSD) derivatives as designer drugs...
