Pharmacokinetics, systemic toxicity, thermoregulation and acute behavioural effects of 25CN‐NBOMe

Addiction Biology August 4, 2022 Klára Šíchová, Kateřina Syrová, Edita Kofroňová et al. 8 citations

agonists containing substances emerging on the illicit drug market as a replacement for N,N-diethyllysergamide (LSD). Despite the increasing use of NBOMes for diagnostic, research and recreational purposes, only a limited number of studies have focussed on their in vivo effect. Here, we investigated pharmacokinetics, systemic toxicity, thermoregulation in individually and group-housed animals,...

Naphyrone (naphthylpyrovalerone): Pharmacokinetics, behavioural effects and thermoregulation in Wistar rats

Addiction Biology May 7, 2020 Nikola Pinterová, Rachel R. Horsley, Hynek Danda et al. 13 citations

Naphthylpyrovalerone (naphyrone) is a pyrovalerone cathinone that potently inhibits monoamine transporters and provides stimulatory-entactogenic effects. Little is known about the safety of naphyrone or its effects in vivo, and more research is needed to acquire knowledge about its fundamental effects on physiology and behaviour. Our objective was to investigate naphyrone's pharmacokinetics,...

Synthesis and identification of deschloroketamine metabolites in rats' urine and a quantification method for deschloroketamine and metabolites in rats' serum and brain tissue using liquid chromatography tandem mass spectrometry

Drug Testing and Analysis October 31, 2019 Kateřina Hájková, Bronislav Jurásek, Jan Čejka et al. 12 citations

Deschloroketamine (2-(methylamino)-2-phenyl-cyclohexanone) is a ketamine analog belonging to a group of dissociative anesthetics, which have been distributed within the illicit market since 2015. However, it was also being sold as 'ketamine' misleading people to believe that they were getting genuine ketamine. Dissociative anesthetics have also come to the attention of the psychiatric field due...

Mephedrone (4-Methylmethcathinone): Acute Behavioral Effects, Hyperthermic, and Pharmacokinetic Profile in Rats

Frontiers in Psychiatry January 10, 2018 Klára Šíchová, Nikola Pinterová, Monika Židková et al. 28 citations

Mephedrone (MEPH) is a synthetic cathinone derivative with effects that mimic MDMA and/or cocaine. Our study in male Wistar rats provides detailed investigations of MEPH's and its primary metabolite nor-mephedrone's (nor-MEPH) pharmacokinetics and bio-distribution to four different substrates (serum, brain, lungs, and liver), as well as comparative analysis of their effects on locomotion [open...

Pharmacokinetic, Ambulatory, and Hyperthermic Effects of 3,4-Methylenedioxy-N-Methylcathinone (Methylone) in Rats

Frontiers in Psychiatry November 17, 2017 Kristýna Štefková, Monika Židková, Rachel R. Horsley et al. 82 citations

-methylcathinone) is a synthetic cathinone analog of the recreational drug ecstasy. Although it is marketed to recreational users as relatively safe, fatalities due to hyperthermia, serotonin syndrome, and multi-organ system failure have been reported. Since psychopharmacological data remain scarce, we have focused our research on pharmacokinetics, and on a detailed evaluation of temporal...
