Fatal intoxication by 5F-ADB and diphenidine: Detection, quantification, and investigation of their main metabolic pathways in humans by LC/MS/MS and LC/Q-TOFMS.

Drug Testing and Analysis February 1, 2018 Maiko Kusano, Kei Zaitsu, Kentaro Taki et al.

Despite the implementation of a new blanket scheduling system in 2013, new psychoactive substance (NPS) abuse remains a serious social concern in Japan. We present a fatal intoxication case involving 5F–ADB (methyl 2‐[1‐(5‐fluoropentyl)‐1 H –indazole‐3‐carboxamido]‐3,3‐dimethylbutanoate) and diphenidine. Postmortem blood screening by liquid chromatography/quadrupole time‐of‐flight mass...

Urinary Excretion Profiles of 5-Methoxy-N,N-diisopropyltryptamine and Its Relevant Metabolites in Humans

JOURNAL OF HEALTH SCIENCE 2007 Tooru Kamata, Munehiro Katagi, Hiroe T Kamata et al. 4 citations

5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT), a psychotomimetic tryptamine derivative, and its relevant metabolites have been determined in eleven urine specimens from six 5-MeO-DIPT users, and their excretion profiles have been investigated by gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS). Three metabolites,...

Metabolism of the psychotomimetic tryptamine derivative 5-methoxy-N,N-diisopropyltryptamine in humans: identification and quantification of its urinary metabolites.

Drug metabolism and disposition: the biological fate of chemicals February 1, 2006 Tooru Kamata, Munehiro Katagi, Hiroe T Kamata et al.

The urinary metabolites of 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT) in humans have been investigated by analyzing urine specimens from its users. For the unequivocal identification and accurate quantification of its major metabolites, careful analyses were conducted by gas chromatography/mass spectrometry, liquid chromatography/mass spectrometry, and liquid chromatography-tandem mass...
