Although at a slower rate, new psychoactive substances continue to appear on the illicit drug market, challenging their detection in biological specimens by forensic and clinical toxicologists. Here, we report in vitro and in vivo metabolism of a new synthetic cannabinoid, methyl 3,3-dimethyl-2-[1-(pent-4-en-1-yl)-1H-indazole-3-carboxamido] butanoate (MDMB-4en-PINACA). This is the first report on metabolism of a synthetic cannabinoid with an alkene functional group at the alkyl side chain. MDMB…

The main phase I metabolites of 4F-MDMD-BICA were successfully characterized, and the routine analytical method with related sample preparation procedure provided a reliable analytical tool for screening both 4F and its selected metabolites in urine and blood samples.

Metabolism of ADB-4en-PINACA in Zebrafish and Rat Liver Microsomes Determined by Liquid Chromatography–High Resolution Mass Spectrometry

The zebrafish model is identified as a promising tool for elucidating the metabolism of NPS and Hydroxylation (M3), ketone (M10), and dihydrodiol (M15) metabolites can be recommended as metabolic markers for ADB-4en-PINACA.

Comparison between human liver microsomes and the fungus Cunninghamella elegans for biotransformation of the synthetic cannabinoid JWH-424 having a bromo-naphthyl moiety analysed by high-resolution mass spectrometry

The metabolic disagreement suggests the necessity to verify the human metabolites in authentic urine samples, while H9 and H10 (Hydroxynaphthalene), H8 (ipso substitution), F22 (hydroxypentyl), and F17 (dihydroxypENTyl) are recommended for monitoring of JWH-424 in urinalysis.

Metabolism of MMB022 and identification of dihydrodiol formation in vitro using synthesised standards.

The metabolic pathways were investigated using synthesised metabolites and revealed that M5 is an end product of the pathways, indicating that it might become a more abundant metabolite in vivo depending on the rate of metabolism in humans.

A Systematic Study of the In Vitro Pharmacokinetics and Estimated Human In Vivo Clearance of Indole and Indazole-3-Carboxamide Synthetic Cannabinoid Receptor Agonists Detected on the Illicit Drug Market

Valinate and tert-leucinate indole and indazole-3-carboxamide SCRAs are often rapidly metabolised in vitro but are highly protein bound in vivo and therefore predicted in vivo CLH is much slower than CLint, likely to give rise to longer detection windows of these substances and their metabolites in urine.

The next generation of synthetic cannabinoids: Detection, activity, and potential toxicity of pent-4en and but-3en analogues including MDMB-4en-PINACA.

Results from toxicology testing paired with case history show the potential for MDMB-4en-PINACA to cause or contribute to impairment or death and Forensic scientists, public health and public safety officials, law enforcement, clinicians, medical examiners, and coroners should consider involvement of emergent synthetic cannabinoids in their work and that new analogues containing an alkene tail can retain similar or increased potency and toxicity.

Synthesis and in Vitro Cannabinoid Receptor 1 Activity of Recently Detected Synthetic Cannabinoids 4F-MDMB-BICA, 5F-MPP-PICA, MMB-4en-PICA, CUMYL-CBMICA, ADB-BINACA, APP-BINACA, 4F-MDMB-BINACA, MDMB-4en-PINACA, A-CHMINACA, 5F-AB-P7AICA, 5F-MDMB-P7AICA, and 5F-AP7AICA.

This study confirms that recently detected SCRAs 4F-MDMB-BICA, 5F-MPP-PICA, MMB-4en-Pica, CUMYL-CBMICA, ADB-BINACA, APP-BinACA, 4F and 5F were all able to activate the CB1 receptor in vitro, albeit to different extents, and are potentially psychoactive in vivo.



Metabolic profiling of synthetic cannabinoid 5F-ADB by human liver microsome incubations and urine samples using high-resolution mass spectrometry.

The in vitro metabolism of 5F-ADB was investigated by using pooled human liver microsomes assay and liquid chromatography-high-resolution mass spectrometry (LC-HRMS) and identified 20 metabolites formed via ester hydrolysis, N-dealkylation, oxidative defluorination, hydroxylations, dehydrogenation, further oxidation to N-pentanoic acid and glucuronidation or a combination of these reactions in vitro.

Sensitive identification and quantitation of parent forms of six synthetic cannabinoids in urine samples of human cadavers by liquid chromatography–tandem mass spectrometry

Human urine samples are easier to obtain than human blood samples due to noninvasiveness. The urine levels of synthetic cannabinoids (SCs) in unchanged forms, however, are usually much lower than

In Vitro and In Vivo Human Metabolism of Synthetic Cannabinoids FDU-PB-22 and FUB-PB-22

The present study aims to identify appropriate analytical markers by investigating FDU- PB-22 and FUB-PB-22 metabolism in human hepatocytes and confirming the results in authentic urine specimens, and recommends M6 (hydroxylated FBI-COOH) and M7 (FBI-CooH) as suitable urinary markers for documenting FDU, PB,22 and/or FUB,PB- 22 intake.

The data suggest that CYP2D6 is quantitatively more important than CYP3A in the metabolism of CJ-12,458 by a factor of about 2 to 1, and a mechanism for this reaction is proposed involving epoxidation, an exocyclic hydride shift, and reduction at the benzylic position.
