Abstract

Two new types of synthetic cannabinoids, an AM-2201 benzimidazole analog (FUBIMINA, 1) and (4-methylpiperazin-1-yl)(1-pentyl-1H-indol-3-yl)methanone (MEPIRAPIM, 2), and three newly emerged phenethylamine derivatives, 25B-NBOMe (3), 2C-N-NBOMe (4), and a 25H-NBOMe 3,4,5-trimethoxybenzyl analog (5), were detected in illegal products distributed in Japan. The identification was based on liquid chromatography–mass spectrometry (LC–MS) and gas chromatography–mass spectrometry (GC–MS), high-resolution MS, and nuclear magnetic resonance analyses. Different from the representative synthetic cannabinoids, such as JWH-018, which have a naphthoylindole moiety, compounds 1 and 2 were completely new types of synthetic cannabinoids; compound 1 had a benzimidazole group in place of an indole group, and compound 2 had a 4-methylpiperazine group in place of the naphthyl group. Compounds 3 and 4 were N-o-methoxybenzyl derivatives of 2,5-dimethoxyphenethylamines (25-NBOMe series), which had been previously detected in European countries, but have newly emerged in Japan. Compound 5 had an N-trimethoxybenzyl group in place of an N-o-methoxybenzyl group. Data on the chemistry and pharmacology of compounds 1, 2, and 5 have never been reported to our knowledge.
