[PMID: 37355149 DOI: 10.1016/j.gene.2023.147585] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 06/03/2023] [Accepted: 06/20/2023] [Indexed: 06/26/2023]
Abstract
The endocannabinoid system receptors, cannabinoid receptors type-1 (CBR-1) and -2 (CBR-2), are implicated in several behavioral and cognitive processes. Many studies have indicated a correlation between cannabinoid receptors and angiogenesis. The current study aims to reveal the possible molecular signaling involved in brain angiogenesis induced by the activation of CBR-1 and CBR-2. We investigated whether the synthetic cannabinoid XLR-11, an agonist of CBR-1 and CBR-2, influences the mRNA and protein expression of vascular endothelial growth factor (VEGF), angiopoietin-1 (ANG1) and -2 (ANG2) in human brain microvascular endothelial cells (hBMVEs). Furthermore, we determined the phosphorylation of glycogen synthase kinase 3 beta (GSK3B) expression. Treatment of hBMVEs cells with XLR-11 elevated the mRNA levels of VEGF, ANG1, and ANG2. The secretion of these proangiogenic factors was increased in the media. Furthermore, the intracellular expression of VEGF, ANG1, ANG2, and GSK3B was significantly increased. This current research provides a new possible approach by targeting the cannabinoid receptors to control and regulate brain angiogenesis for treating a variety of angiogenesis-related diseases. This could be achived by using different agonists or antagonists of the cannabinoid receptors based on the nature of the diseases.

Abstract
Metabolite profiling is an indispensable part of drug discovery and development, enabling a comprehensive understanding of the drug's metabolic behavior. Liquid chromatography-mass spectrometry facilitates metabolite profiling by reducing sample complexity and providing high sensitivity. This review discusses the in vivo metabolite profiling involving LC-MS/MS and the utilization of QTOF, QQQ mass analyzers with a particular emphasis on a mass filter. Further, a summary of sample extraction procedures in biological matrices such as plasma, urine, feces, serum and hair as in vivo samples are outlined. toward the end, we present 15 case studies in biological matrices and their LC-MS/MS conditions to understand the metabolic disposition.

Florou D, Boumba VA. Hair analysis for New Psychoactive Substances (NPS): Still far from becoming the tool to study NPS spread in the community? Toxicol Rep 2021; 8:1699-1720. [PMID: 34646750 PMCID: PMC8501677 DOI: 10.1016/j.toxrep.2021.09.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 09/08/2021] [Accepted: 09/13/2021] [Indexed: 11/24/2022] Open
Abstract
In this review article, we performed an overview of extraction and chromatographic analysis methods of NPS in hair from 2007 to 2021, evaluating the limit of detection (LOD), limit of quantification (LOQ), limit of reporting (LOR), and limit of identification (LOI) values reported for each NPS. Our review aimed to highlight the limitations of modern hair analytical techniques, and the prerequisites for the proper evaluation and use of analytical results in relation to the objectives of NPS hair analysis. In the selected studies the detection of a total of 280 NPS was reported. The detected NPS belonged to seven classes: synthetic cannabinoids with 109 different substances, synthetic opioids with 58, cathinones with 50, phenethylamines with 34, other NPS with 15, tryptamines with ten, and piperazines with four substances. The NPS hair analysis of real forensic/ clinical cases reported the detection of only 80 NPS (out of the 280 targeted), in significantly higher levels than the respective LODs. The analytical protocols reviewed herein for NPS hair analysis showed continuously growing trends to identify as many NPS as possible; the extraction methods seem to have a limited potential to improve, while the various mass spectroscopic techniques and relevant instrumentation provide an enormous field for development and application. Hair is a biological indicator of the past chronic, sub-chronic, and, even, in certain cases, acute exposure to xenobiotics. Therefore, future research in the field could progress NPS hair analysis and aim the monitoring of NPS expansion and extent of use in the community.

Abstract
New psychoactive substances (NPS) are a wide group of compounds that try to mimic the effects produced by the 'classical' illicit drugs, including cannabis (synthetic cannabinoids), cocaine and amphetamines (synthetic cathinones) or heroin (synthetic opioids), and which health effects are still unknown for most of them. Nowadays, more than 700 compounds are being monitored by official organisms, some of which have been recently identified in seizures and/or intoxication cases. Toxicological analysis plays a pivotal role in NPS research. A comprehensive investigation on NPS, from the first identification of a novel substance until its detection in drug users to help in diagnostics and medical treatment, requires the use of a wide variety of instruments and analytical strategies. This paper illustrates the key role of mass spectrometry (MS) along a comprehensive investigation on NPS. The synthetic cannabinoid XLR-11 and the synthetic cathinone 5-PPDi have been chosen as representative substances of the most consumed NPS families. Moreover, both compounds have been investigated at our laboratory in different stages of the three-step strategy considered in this article. The initial identification and characterisation of the compound in consumption products, the first reported metabolic pathway and the development of analytical methodologies for its determination (and/or their metabolites) in different toxicological samples are described. The analytical strategies and MS instruments are briefly discussed to show the reader the possibilities that MS instrumentation offer to analytical scientists. This publication aims to be a starting point for those interested on the NPS research field from an analytical chemistry point of view.

Abstract
Synthetic cannabinoids (SCs), mimicking the psychoactive effects of cannabis, consist of a vast array of structurally diverse compounds. A novel compound belonging to the SC family, (1-(cyclohexylmethyl)-1H-indol-3-yl)-(2,2,3,3-tetramethylcyclopropyl)methanone (named TMCP-CHM in this article) contains a cyclopropane ring that isomerizes during the smoking process, resulting in a ring-opened thermal degradant with a terminal double bond in its structure. Metabolites of TMCP-CHM were tentatively identified in vitro (after incubation of the parent substance with S9 pooled human liver fraction) and in vivo (rat experimental model) studies by accurate-mass liquid chromatography-tandem mass spectrometry (LC-MS/MS). For the identification of the degradant metabolites, and to study biotransformation of parent substance in the human, urine and hair samples from patients, who had ingested the compound and were subsequently admitted to hospital with drug intoxications, were analyzed. Products of mono-, di-, trihydroxylation, carboxylation, and carboxylation combined with hydroxylation of TMCP-CHM and its degradant were detected in human urine. Metabolism of the degradant included addition of water to the terminal double bond followed by dehydration and formation of a cyclic metabolite. Degradant metabolites prevailed in comparison with metabolites of the parent substance in each metabolite group examined, except carboxylation. N-Dealkylated metabolites found in human urine originated only from the degradant. Most of the hydroxy metabolites were detected in human urine in both the free form and as glucuronides. The detection of monohydroxylated (M1.1-M1.3, M/A1.10) and carboxylated/hydroxylated (M4.2, M/A4.3) metabolites of TMCP-CHM and the hydrated form of the monohydroxylated metabolite of the degradant was found to be convenient for routine analysis.

Abstract
Synthetic cannabinoids, a new class of psychoactive substances, are potent agonists of cannabinoid receptors, which mimic the psychoactive effects of the principal psychoactive component of cannabis, ∆9-tetrahydrocannabinol. Despite governmental scheduling as illicit drugs, new synthetic cannabinoids are being produced. The abuse of synthetic cannabinoids with several drugs containing different chemical groups has resulted in large numbers of poisonings. This has increased the urgency for forensic and public health laboratories to identify the metabolites of synthetic cannabinoids and apply this knowledge to the development of analytical methods and for toxicity prediction. It is necessary to determine whether synthetic cannabinoids are involved in drug-metabolizing enzyme-mediated drug-drug interactions. This review describes the metabolic pathways of 13 prevalent synthetic cannabinoids and various drug-metabolizing enzymes responsible for their metabolism, including cytochrome P450 (CYP), UDP-glucuronosyltransferases (UGTs), and carboxylesterases. The inhibitory effects of synthetic cannabinoids on CYP and UGT activities are also reviewed to predict the potential of synthetic cannabinoids for drug-drug interactions. The drug-metabolizing enzymes responsible for metabolism of synthetic cannabinoids should be characterized and the effects of synthetic cannabinoids on CYP and UGT activities should be determined to predict the pharmacokinetics of synthetic cannabinoids and synthetic cannabinoid-induced drug-drug interactions in the clinic.

Abstract
Since the first detection of synthetic cannabinoids (SCs) in so-called 'legal high' products (e.g. 'Spice') sold as legal alternatives to marihuana, the rapid development of this class of designer drugs poses a great challenge for analytical laboratories. The aim of this study was the comprehensive validation of an up-to-date LC-MS/MS method for detection of SCs in human hair for the purpose of drug abstinence testing and evaluation of a pragmatic re-validation approach for frequent method adaption. The validation demonstrated low quantification limits (0.5-5.0 pg mg-1) and acceptable selectivity, linearity, accuracy, and precision for 72 SCs. High matrix effects have been taken into consideration as a major limitation of the method. The partial re-validation approach proved to be an appropriate compromise between reduced validation effort and sufficient control of the method performance enabling analysts to keep pace with the dynamics of the drug market. The analysis of 294 authentic samples resulted in 163 positive samples and showed a broad concentration range (<1.0-5,700 pg mg-1) for 52 SCs in hair with up to 17 different compounds detected in a single hair sample. Periods of detection between one and 58 months were observed for single compounds in hair. Regarding the interpretation of analytical findings semi-quantitative concentrations were considered sufficient for a rough classification of the intensity of drug exposure in (i) passive exposure or exposure in the distant past (lower pg mg-1 range), (ii) more intense exposure (elevated concentration range, >20 pg mg-1 (upper 25th-percentile)), and (iii) heavy/recent exposure (>150 pg mg-1).

Abstract
New Psychoactive Substances (NPS) belong to several chemical classes, including phenethylamines, piperazines, synthetic cathinones and synthetic cannabinoids. Development and validation of analytical methods for the determination of NPS both in traditional and alternative matrices is of crucial importance to study drug metabolism and to associate consumption to clinical outcomes and eventual intoxication symptoms. Among different biological matrices, hair is the one with the widest time window to investigate drug-related history and demonstrate past intake. The aim of this paper was to overview the trends of the rapidly evolving analytical methods for the determination of NPS in hair and the usefulness of these methods when applied to real cases. A number of rapid and sensitive methods for the determination of NPS in hair matrix has been recently published, most of them using liquid chromatography coupled to mass spectrometry. Hair digestion and subsequent solid phase extraction or liquid-liquid extraction were described as well as extraction in organic solvents. For most of the methods limits of quantification at picogram per milligram hair were obtained. The measured concentrations for most of the NPS in real samples were in the range of picograms of drug per milligram of hair. Interpretation of the results and lack of cut-off values for the discrimination between chronic consumption and occasional use or external contamination are still challenging. Methods for the determination of NPS in hair are continually emerging to include as many NPS as possible due to the great demand for their detection.

Abstract
In May 2016, a new type of synthetic indazole-3-carboxamide cannabinoid (CUMYL-4CN-BINACA) was detected in seized plant material submitted to the Istanbul Council of Forensic Medicine by the National Police Office. The major ingredient in this material was purified using preparative liquid chromatography, and its structure was identified using liquid chromatography-high-resolution mass spectrometry (LC-HR/MS), gas chromatography-electron ionization/mass spectrometry (GC-EI/MS), nuclear magnetic resonance (NMR) spectroscopy and Fourier transform-infrared spectroscopy (FT-IR). Using HR-MS, the molecular formula of the compound was determined to be C22H24N4O (MW = 360.1950). The 1H and 13C-NMR and FT-IR spectrometric data revealed that the structure of compound was 1-(4-cyanobutyl)-N-(2-phenylpropan-2-yl)-1H-indazole-3-carboxamide (CUMYL-4CN-BINACA). After identification, it was quickly added to our generic drug list, and an ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS-MS) method was developed to determine its presence in blood samples. This study reports on the identification of CUMYL-4CN-BINACA in plant material using LC-HR/MS, GC-EI/MS, NMR and FT-IR as well as a validated method for quantification of CUMYL-4CN-BINACA in post-mortem blood samples by UPLC-MS-MS analysis. The quantification method has been validated in terms of linearity (0.1-50 ng/mL), selectivity, intra- and inter-assay accuracy and precision (CV < 15%), recovery (94-99%), limit of detection (0.07 ng/mL) and limit of quantification (0.1 ng/mL). Matrix effects, stability and process efficiency were also assessed. The method has been applied to 2,350 post-mortem blood samples from the autopsy cases in the Morgue Department of the Council of Forensic Medicine (Istanbul, Turkey) between 1 July 2016 and 31 December 2016.

Abstract
Synthetic cannabinoids (SC) belong to the emergent market of new psychoactive substances, sold on the Internet or specialized shops. Since the 1970s, more than 160 new SC have invaded the drug market. These substances imitate the psychoactive effects of cannabis. Underestimated for too long, SC's market growth and consequences are no longer to be ignored, first of all in terms of public health. SC were first synthesized during researches on the endocannabinoid system. Though they are agonists of the cannabinoid receptors 1 and 2, as Δ9-tetrahydrocannabinol in cannabis, they can also have a really high affinity with these receptors, rising up their potency. Each country in the world has chosen various ways how to deal with SC: scheduling, blanket ban, regulation… In order to contour the legal system, producers regularly modify the chemical formulas of those substances and hand out an attracting packaging looking harmless. However, the content of those small packets is extremely unstable and unreliable, including harmful compounds to health. Reports show an increasing number of non-fatal intoxications but also fatalities. Consequences on the body are numerous but there have been also reports of mental health imbalance and appearances of addiction-linked clinical signs. This review of literature aims at establishing a picture on SC in order to raise awareness among professionals in the health field on this new addiction matrix.
