5F-ADB-PINACA Wikipedia

In-vitro metabolism studies are generally used to complement these data using perfused organs, tissue or cell cultures and microsomal preparations amongst which pooled human liver microsomes (HLM) have been frequently used to elucidate metabolism of SCBs [12,13,14,15,16


The % peak area abundance ratio of metabolites detected in the urine samples are often affected by numerous factors such as drug intake behaviour (intake route, amount of drug and intake frequency), time from last drug intake and metabolic stability. This indicated that the phase I metabolism of 4F-MDMB-BINACA are unlikely to be affected significantly by polydrug intake. Oxidative defluorination with subsequent butanoic acid formation (B17) metabolite, the second major metabolite after monohydroxylation in the C. Ester hydrolysis with dehydrogenation formed in-vivo in this study was also reported among other indazole carboxamide type SCBs with tert-leucine methyl ester moieties such as 5F-MDMB-PINACA and MDMB-4en-PINACA [39, 40]. Similar to the in-vivo findings, 4F-MDMB-BINACA ester hydrolysis (B22) was the major metabolite for both HepG2 and HLM models, consistent with the known hydrolytic activity of CES reported

Each training session lasted a maximum of 10 min, and the rats could earn up to 20 food pellets. Thirty minutes prior to the training sessions, rats received an injection of either vehicle or Δ9-THC and were subsequently placed in the behavior-testing chambers, where food (45-mg food pellets; Bio-Serve, Frenchtown, NJ) was available as a reinforcer for every ten responses (FR10) on a designated injection appropriate lever. A houselight was centered over the hopper close to the ceiling and was illuminated only when the levers were active. Each dose range included doses that were without effect to those producing at least 50% depression compared to vehicle control. Twenty-four male Sprague-Dawley rats were obtained from Envigo (Houston, TX). Male ND4 Swiss–Webster mice were obtained from Envigo (Houston, TX) at approximately 8 weeks of age and maintained in the University of North Texas Health Science Center (UNTHSC) animal facility for two weeks prior to testin


LC separates the urine or blood sample and QTOF-MS provides high-resolution and accurate mass measurements for precise identification and structural elucidation of compounds. The LC-QTOF-MS method offers a more comprehensive and sensitive approach for drug detection, covering hundreds of recreational drugs, including NPS. Besides increasing the temperature to enlarge the drug aerolisation and bioavailability, one can elevate the flow rate of air through the e-cigarette and/or add a diluent . Of all e-cigarette users registered at this forum, 7.8 % vaped SCRAs . About 15 % of individuals registered at forums for drug users such as erowid.org who vaped cannabis have also vaped SRCAs. SCRAs belong, together with synthetic opioids, cathinones, amphetamines and hallucinogens to the new psychoactive substances (NPS) that are currently developed at high speed.

LC-QTOF-MS represents a significant advancement in the field of drug detection, offering higher sensitivity, specificity, and a broader spectrum of detectable substances. Despite all negative results in the point-of-care test for recreational drugs, the liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) analysis showed that the liquid of the e-cigarette contained ADB-BUTINACA, a synthetic cannabinoid. We report a 27-year-old man who was admitted to the emergency room because of sudden Recommended Resource site headache, nausea, vertigo, red eyes and palpitations. Synthetic cannabinoids are gaining popularity globally and detection is not commonly available.
Data availability
When clinical presentation and/or initial DOA testing results are inconclusive, additional testing with LC-QTOF-MS can be valuable and is recommended. SCRAs and other NPS may not be detected by point-of-care DOA tests. In this case, the point-of-care DOA urine screening was not able to detect the synthetic cannabinoid ADB-BUTINAC

Despite the relatively high % peak area ratio and detection in 16/20 urine samples, ester hydrolysis followed by monohydroxylation at the tert-leucine moiety (m/z 366, B8) metabolite was not reported among the 17 urine samples from the forensic psychiatric ward and prison in Haschimi et al.’s study

Eight in-vivo metabolites tentatively identified were mainly products of ester hydrolysis with or without additional dehydrogenation, N-dealkylation, monohydroxylation and oxidative defluorination with further oxidation to butanoic aci


Inclusion in an NLM database does not imply endorsement of, or agreement with, the contents by NLM or the National Institutes of Health. It is illegal to sell, distribute, supply, transport or trade the pharmaceutical drug under the Psychoactive Substances Act 2016. The corresponding indole core analogue, 4F-MDMB-BICA (4F-MDMB-BUTICA), has also been widely sold as a designer drug by chemical providers on the internet, first being identified in May 2020. It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018. 4F-MDMB-BINACA (also known as MDMB-4F-BINACA using systematic EMCDDA nomenclature or 4F-MDMB-BUTINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family.
