Newest firstThe rapid structural evolution and extensive metabolism of synthetic cannabinoid receptor agonists (SCRAs) following consumption makes their detection in biological samples challenging, especially in urine. In vitro metabolite identification studies are an essential tool for identifying analytical targets to confirm SCRA consumption in clinical and forensic toxicology casework. Systematic studies on structurally r…
Open article record in new tab ↗An emerging new trend reveals that potent synthetic cannabinoid receptor agonists (SCRAs) that were prevalent prior to the Chinese class-wide ban in July 2021 have remained on the market or re-emerged. This is likely because of a new production route where unscheduled tail-less precursors are converted into the desired controlled SCRA via a one-step synthesis. This study reports the discovery of a clandestine prod…
Synthetic cannabinoid receptor agonists (SCRAs) are a group of new psychoactive substances (NPS) that bind to and activate the cannabinoid 1 and 2 (CB1 and CB2) receptors. Following the introduction of SCRA analog controls in China in July 2021, new SCRAs with a bromine at the 5 position on the indazole core emerged on the recreational drug market. In this study, the in vitro CB1 receptor activity of 19 different…
Synthetic cannabinoid receptor agonists (SCRAs) remain a major public health concern, with their use implicated in intoxications and drug-related deaths worldwide. Increasing our systematic understanding of SCRA metabolism supports clinical and forensic toxicology casework, facilitating the timely identification of analytical targets for toxicological screening procedures and confirmatory analysis. This is particu…
In vitro pharmacokinetic studies were conducted on enantiomer pairs of twelve valinate or tert-leucinate indole and indazole-3-carboxamide synthetic cannabinoid receptor agonists (SCRAs) detected on the illicit drug market to investigate their physicochemical parameters and structure-metabolism relationships (SMRs). Experimentally derived Log D7.4 ranged from 2.81 (AB-FUBINACA) to 4.95 (MDMB-4en-PINACA) and all SC…
Synthetic cannabinoid receptor agonists (SCRAs) have been the largest group of illicit psychoactive substances reported to international monitoring and early warning systems for many years. Carboxamide-type SCRAs are amongst the most prevalent and potent. Enantiospecific synthesis and characterization of four indazole-3-carboxamides, AMB-FUBINACA, AB-FUBINACA, 5F-MDMB-PINACA (5F-ADB), and AB-CHMINACA is reported.…
