Namera A, Kawamura M, Nakamoto A, Saito T, Nagao M - Forensic Toxicol (2015)

Bottom Line: Like synthetic cannabinoids, cathinone analogs are also abused and cause serious problems worldwide.Various analytical methods that can cope with the rapid changes in chemical structures are required for routine analysis and screening of these drugs in seized and biological materials for forensic and clinical purposes.Although many chromatographic methods to analyze each drug have been published, there are only a few articles summarizing these analytical methods.

ABSTRACT

A number of N-alkyl indole or indazole-3-carbonyl analogs, with modified chemical structures, are distributed throughout the world as synthetic cannabinoids. Like synthetic cannabinoids, cathinone analogs are also abused and cause serious problems worldwide. Acute deaths caused by overdoses of these drugs have been reported. Various analytical methods that can cope with the rapid changes in chemical structures are required for routine analysis and screening of these drugs in seized and biological materials for forensic and clinical purposes. Although many chromatographic methods to analyze each drug have been published, there are only a few articles summarizing these analytical methods. This review presents the various colorimetric detections, immunochemical assays, gas chromatographic-mass spectrometric methods, and liquid chromatographic-mass spectrometric methods proposed for the analysis of synthetic cannabinoids and cathinones.

Mentions: Mass spectral profiles of cathinones are very simple in the positive mode of GC–MS, because only the base peak originating from the immonium ion in each molecule is observed. The probable fragmentation pathways of cathinones are described in previous articles [61–64] and are shown in Fig. 5. However, this phenomenon makes the identification of cathinones difficult. To help identify cathinones, other information, such as tandem mass spectrometric data, are usually used because more structural information about the molecule is obtained.Fig. 5
