Identification and characterization of an indazole-3-carboxamide class synthetic cannabinoid: 2-[1-(cyclohexylmethyl)-1H-indazole-3-carboxamido]-3,3-dimethylbu tanoic acid (DMBA-CHMINACA)

초록

Illicit psychoactive substances have threatened public health worldwide. An active metabolite of ADB-CHMINACA and MDMB-CHMINACA was identified for the first time in a powder-type product found in an airmail package. The structure of compound 1 was elucidated by a combination of gas chromatography-mass spectrometry (GC-MS), liquid chromatography-high resolution mass spectrometry (LC-HRMS), infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. Compound 1 was proven to be an analogue of MDMB-CHMINACA, an indazole-based synthetic cannabinoid. The methyl ester group in MDMB-CHMINACA was replaced with a carboxylic acid group in compound 1. Compound 1 was determined as 2-[ 1-(cyclohexylmethyl)-1H-indazole-3-carboxamido]-3,3-dimethylbutanoic acid and named as DMBA-CHMINACA. (c) 2018 Elsevier B.V. All rights reserved.
