Abstract

Purpose: 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.

Methods: The structures of the compounds were determined by gas chromatography-mass spectrometry, liquid chromatography-photodiode array-mass spectrometry, liquid chromatography with hybrid quadrupole time-of-flight mass spectrometry and nuclear magnetic resonance (NMR) measurement.

Results: From the NMR analysis, two compounds in the products were identified as N,N-diethyl-7-methyl-4-(3-(trimethylsilyl)propanoyl)-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (1S-LSD) and 7-allyl-N,N-diethyl-4-(thiophene-2-carbonyl)-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (1T-AL-LAD). In the product where 1S-LSD was detected, the presence of a trace amount of iso-1S-LSD, a C8-epimerization product of 1S-LSD, was suggested.

Conclusions: This paper is the first to report the detection of 1S-LSD and 1T-AL-LAD in sheet products in Japan. Notably, the metabolic pathways and biological activities of 1S-LSD and 1T-AL-LAD are not explored. The possibility of the in vivo deacylation and conversion of the compoundsinto LSD or AL-LAD should be further investigated.

期刊介绍： The journal Forensic Toxicology provides an international forum for publication of studies on toxic substances, drugs of abuse, doping agents, chemical warfare agents, and their metabolisms and analyses, which are related to laws and ethics. It includes original articles, reviews, mini-reviews, short communications, and case reports. Although a major focus of the journal is on the development or improvement of analytical methods for the above-mentioned chemicals in human matrices, appropriate studies with animal experiments are also published. Forensic Toxicology is the official publication of the Japanese Association of Forensic Toxicology (JAFT) and is the continuation of the Japanese Journal of Forensic Toxicology (ISSN 0915-9606).
