Detection of ADB-BUTINACA Metabolites in Human Urine, Blood, Kidney and Liver
J Anal Toxicol 2022 Jul 14;46(6):641-650.PMID:34341821DOI:10.1093/jat/bkab088.
The N-butyl indazole derivative, N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-butyl-1H-indazole-3-carboxamide (ADB-BUTINACA or ADB-BINACA), currently a drug of abuse in Russia, is reported to have a cannabinoid receptor potency and efficacy almost three times higher than JWH-018. ADB-BUTINACA was detected in blood from patients with suspected drug intoxications, as well as in blood, kidney and liver samples collected during postmortem investigations. Using liquid chromatography-time-of-flight-mass spectrometry, a number of ADB-BUTINACA metabolites were tentatively identified in urine samples. These include products of mono- and dihydroxylation, hydroxylation of the N-butyl side chain and dehydrogenation, formation of a dihydrodiol, hydrolysis of the terminal amide group, N-dealkylation of the indazole and a combination of these reactions. The dihydrodiol was found to be the predominant metabolite, with its chromatographic peak area exceeding those of other metabolites by almost an order of magnitude. For the routine analysis of blood, liver and kidney samples, the dihydrodiol and monohydroxylated metabolites along with the parent compound are recommended as target analytes. The same metabolites in free and glucuronidated forms are also recommended for analytical confirmation in urine samples.
Structure-activity relationships of valine, tert-leucine, and phenylalanine amino acid-derived synthetic cannabinoid receptor agonists related to ADB-BUTINACA, APP-BUTINACA, and ADB-P7AICA
RSC Med Chem 2021 Oct 25;13(2):156-174.PMID:35308023DOI:10.1039/d1md00242b.
Synthetic cannabinoid receptor agonists (SCRAs) remain one the most prevalent classes of new psychoactive substances (NPS) worldwide, and examples are generally poorly characterised at the time of first detection. We have synthesised a systematic library of amino acid-derived indole-, indazole-, and 7-azaindole-3-carboxamides related to recently detected drugs ADB-BUTINACA, APP-BUTINACA and ADB-P7AICA, and characterised these ligands for in vitro binding and agonist activity at cannabinoid receptor subtypes 1 and 2 (CB1 and CB2), and in vivo cannabimimetic activity. All compounds showed high affinity for CB1 (K i 0.299-538 nM) and most at CB2 (K i = 0.912-2190 nM), and most functioned as high efficacy agonists of CB1 and CB2 in a fluorescence-based membrane potential assay and a βarr2 recruitment assay (NanoBiT®), with some compounds being partial agonists in the NanoBiT® assay. Key structure-activity relationships (SARs) were identified for CB1/CB2 binding and CB1/CB2 functional activities; (1) for a given core, affinities and potencies for tert-leucinamides (ADB-) > valinamides (AB-) ≫ phenylalaninamides (APP-); (2) for a given amino acid side-chain, affinities and potencies for indazoles > indoles ≫ 7-azaindoles. Radiobiotelemetric evaluation of ADB-BUTINACA, APP-BUTINACA and ADB-P7AICA in mice demonstrated that ADB-BUTINACA and ADB-P7AICA were cannabimimetic at 0.1 mg kg-1 and 10 mg kg-1 doses, respectively, as measured by pronounced decreases in core body temperature. APP-BUTINACA failed to elicit any hypothermic response up to the maximally tested 10 mg kg-1 dose, yielding an in vivo potency ranking of ADB-BUTINACA > ADB-P7AICA > APP-BUTINACA.
The metabolism of the synthetic cannabinoids ADB-BUTINACA and ADB-4en-PINACA and their detection in forensic toxicology casework and infused papers seized in prisons
Drug Test Anal 2022 Apr;14(4):634-652.PMID:34811926DOI:10.1002/dta.3203.
Early warning systems detect new psychoactive substances (NPS), while dedicated monitoring programs and routine drug and toxicology testing identify fluctuations in prevalence. We report the increasing prevalence of the synthetic cannabinoid receptor agonist (SCRA) ADB-BUTINACA (N-[1-amino-3,3-dimethyl-1-oxobutan-2-yl]-1-butyl-1H-indazole-3-carbox-amide). ADB-BUTINACA was first detected in a seizure in Sweden in 2019, and we report its detection in 13 routine Swedish forensic toxicology cases soon after. In January 2021, ADB-BUTINACA was detected in SCRA-infused papers seized in Scottish prisons and has rapidly increased in prevalence, being detected in 60.4% of the SCRA-infused papers tested between January and July 2021. In this work, ADB-BUTINACA was incubated with human hepatocytes (HHeps), and 21 metabolites were identified in vitro, 14 being detected in authentic case samples. The parent drug and metabolites B9 (mono-hydroxylation on the n-butyl tail) and B16 (mono-hydroxylation on the indazole ring) are recommended biomarkers in blood, while metabolites B4 (dihydrodiol formation on the indazole core), B9, and B16 are suitable biomarkers in urine. ADB-4en-PINACA (N-[1-amino-3,3-dimethyl-1-oxobutan-2-yl]-1-[pent-4-en-1-yl]-1H-indazole-3-carboxamide) was detected in Scottish prisons in December 2020, but, unlike ADB-BUTINACA, prevalence has remained low. ADB-4en-PINACA was incubated with HHeps, and 11 metabolites were identified. Metabolites E3 (dihydrodiol formed in the tail moiety) and E7 (hydroxylation on the linked/head group) are the most abundant metabolites in vitro and are suggested as urinary biomarkers. The in vitro potencies of ADB-BUTINACA (EC50 , 11.5 nM and ADB-4en-PINACA (EC50 , 11.6 nM) are similar to that of MDMB-4en-PINACA (EC50 , 4.3 nM). A third tert-leucinamide SCRA, ADB-HEXINACA was also detected in prison samples and warrants further investigation.
Clinical features associated with ADB-BUTINACA exposure in patients attending emergency departments in England
Clin Toxicol (Phila) 2022 Oct;60(10):1094-1098.PMID:35943421DOI:10.1080/15563650.2022.2101469.
Objective: Synthetic cannabinoid receptor agonists (SCRA) are commonly encountered new psychoactive substances. Here we report the recent detection of ADB-BUTINACA in samples from patients attending United Kingdom emergency departments with toxicity after suspected drug misuse and describe the associated clinical features. Methods: Consenting adults (≥16 y) presenting to participating hospitals with toxicity after suspected drug misuse have been included in the Identification Of Novel psychoActive substances (IONA) study since March 2015. Demographic and clinical features are recorded and blood and/or urine samples analysed using high-resolution accurate mass liquid chromatography-mass spectrometry. Results: By December 2021, analytical data were available for 1279 IONA participants and ADB-BUTINACA was detected in at least one sample from 10 (9 males, age range 16-51 median 45 years), all presenting since February 2021. Smoking 'spice' was reported by four patients, two had ingested edible "cannabis" gums and four reported heroin use (2 intravenous, 1 smoked, 1 route not known). Co-use of pregabalin (oral) and crack cocaine (smoked) were also reported. In 3 cases ADB-BUTINACA was the only substance detected, while in seven other substances of misuse were also detected including other SCRA, opioids, benzodiazepines cocaine and pregabalin. Clinical features reported in these 2 groups respectively included reduced level of consciousness (3/3, 6/7), agitation (0/3, 4/7), tachycardia (0/3, 3/7), seizures (1/3, 1/7), hallucinations (1/3, 1/7), hypotension (1/3, 1/7). Metabolic acidosis (1/3, 0/7) and respiratory acidosis (1/3, 0/7), All 10 patients recovered with supportive care, including intubation and ventilation for one case. The median length of hospital stay was 19 h (range 2.6-131 h). Conclusions: ADB-BUTINACA has recently emerged as a drug of misuse in England. Clinical features of toxicity are consistent with those of other SCRA and include reduced level of consciousness, respiratory and/or metabolic acidosis, seizures, confusion and hallucinations.
Urinary Metabolite Biomarkers for the Detection of Synthetic Cannabinoid ADB-BUTINACA Abuse
Clin Chem 2021 Nov 1;67(11):1534-1544.PMID:34387654DOI:10.1093/clinchem/hvab134.
Background: (S)-N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-butyl-1H-indazole-3carboxamide (ADB-BUTINACA) is an emerging synthetic cannabinoid that was first identified in Europe in 2019 and entered Singapore's drug scene in January 2020. Due to the unavailable toxicological and metabolic data, there is a need to establish urinary metabolite biomarkers for detection of ADB-BUTINACA consumption and elucidate its biotransformation pathways for rationalizing its toxicological implications. Methods: We characterized the metabolites of ADB-BUTINACA in human liver microsomes using liquid chromatography Orbitrap mass spectrometry analysis. Enzyme-specific inhibitors and recombinant enzymes were adopted for the reaction phenotyping of ADB-BUTINACA. We further used recombinant enzymes to generate a pool of key metabolites in situ and determined their metabolic stability. By coupling in vitro metabolism and authentic urine analyses, a panel of urinary metabolite biomarkers of ADB-BUTINACA was curated. Results: Fifteen metabolites of ADB-BUTINACA were identified with key biotransformations being hydroxylation, N-debutylation, dihydrodiol formation, and oxidative deamination. Reaction phenotyping established that ADB-BUTINACA was rapidly eliminated via CYP2C19-, CYP3A4-, and CYP3A5-mediated metabolism. Three major monohydroxylated metabolites (M6, M12, and M14) were generated in situ, which demonstrated greater metabolic stability compared to ADB-BUTINACA. Coupling metabolite profiling with urinary analysis, we identified four urinary biomarker metabolites of ADB-BUTINACA: 3 hydroxylated metabolites (M6, M11, and M14) and 1 oxidative deaminated metabolite (M15). Conclusions: Our data support a panel of four urinary metabolite biomarkers for diagnosing the consumption of ADB-BUTINACA.
