This book was released on 2020-09-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. The use of NPS has been associated with many outbreaks leading to hospitalizations and has been implicated in numerous fatalities worldwide. To be able to analytically detect drugs in a forensic setting is vital in the fight against the abuse of NPS. One of the most notable challenges in detection of NPS is the identification of major urinary metabolites for use as biomarkers. Furthermore, given the lack of reference standards in most metabolism studies, the major urinary metabolites can often only be tentatively determined. This thesis describes the synthesis and analysis of potential metabolites used to identify the exact structures of major metabolites of the synthetic cannabinoid AKB-48, fentanyl and five fentanyl analogues in authentic human urine samples and/or hepatocyte incubations. Synthetic targets were chosen based on previous metabolism studies by our research group. Subsequently, synthetic routes were developed to produce numerous potential metabolites across the studied NPS. The synthesized reference standards were analyzed by LC-QTOF-MS alongside hepatocyte drug incubations and authentic human urine samples. Comparison of the resulting analytical data was used to determine the exact structures of many metabolites. This includes urinary metabolites of AKB-48 with a single hydroxyl group situated on a secondary carbon of the adamantane moiety, or position 3 or 5 of the pentyl side chain. For the studied fentanyls, the ?-OH and the 4’-OH metabolites were abundant metabolites identified in hepatocyte incubations while the 4’-OH, 4’-OH-3’-OMe and 3’,4’-diOH were the favored metabolic motifs among the metabolites identified in urine. Additionally, a concise synthetic route to produce synthetic cannabinoid metabolites with the 4-OH-5F pentyl side chain motif was developed and demonstrated for four synthetic cannabinoids. These findings and the developed synthetic routes can be used to provide forensic toxicology laboratories with urinary biomarkers for drug detection. Moreover, the synthesized reference standards of major metabolites can be studied to better understand the toxicity of their parent drugs. Nya psykoaktiva substanser (NPS) är det officiella namnet för den grupp droger som tidigare har kallats för designerdroger, nätdroger eller internetdroger. NPS definieras som droger som utgör ett likvärdigt hot mot folkhälsan som droger som återfinns på Förenta Nationernas narkotikakonventioner men som själva inte återfinns under dessa konventioner. Det finns hundratals olika rapporterade NPS spridda över olika droggrupper, såsom syntetiska cannabinoider och syntetiska opioider. Vissa av dessa droger syntetiserades ursprungligen i forskningssyfte, men tog sig senare in på den illegala drogmarknaden. De mer nyligen framtagna NPS är ofta designade att efterlikna effekterna av etablerade droger, såsom morfin eller ?9-THC, vilket är den huvudsakliga psykoaktiva substansen i cannabis. Användandet av NPS har associerats till många kluster av intoxikationer som har lett till hospitaliseringar. Många har även dött till följd av användandet av NPS. Inte minst i USA där en grupp av NPS kallad för fentanylanaloger är högst delaktig i den pågående opioidkrisen. Den ständiga inströmningen av nya NPS leder till att detektion av och diskriminering mellan dem utgör en svår utmaning för forensiska toxikologilaboratorier. Tillgången av lämpliga referenssubstanser möter inte deras efterfrågan, delvis på grund av att vilka biomarkörer som är optimala för drogdetektion inte alltid är uppenbart. Till exempel så är metabolismen av syntetiska cannabinoider i regel både snabb och omfattande. Av den anledningen kan användandet av modersubstansen som biomarkör vid analys av urin leda till falskt negativa resultat. Urin som biologisk matris har många fördelar jämfört med blod. Till exempel så har urin ett längre detektionsfönster och högre drogkoncentrationer. För att kunna identifiera optimala biomarkörer för droganalys av urinprover så måste drogernas metabolism utredas. De flesta metabolismstudier använder sig av humana levermikrosomer eller hepatocyter som inkuberas tillsammans med droger för att generera metaboliter in vitro. Urinprover från individer i vilkas blod det har återfunnits droger används också men tillgången är tyvärr begränsad. Dessa metaboliter separeras sedan med hjälp av kromatografiska tekniker och deras kemiska strukturer bestäms med hjälp av masspektrometri. Dock så är utvärderingen av masspektrometridata komplicerad och det är heller inte möjligt att skilja på vissa positionsisomerer genom att enbart analysera masspektrometridata. För att kunna möjliggöra exakt strukturutredning så krävs referensstandarder. Därför var målet med denna avhandling att addera syntes och analys av referensstandarder till de etablerade tillvägagångssätten att studera metabolismen av NPS. Ett stort antal potentiella metaboliter av AKB-48 och andra syntetiska cannabinoider samt av fentanyl och fentanylanaloger syntetiserades. Genom att använda dessa referensstandarder i metabolismstudier så kunde de exakta kemiska strukturerna för många metaboliter bestämmas. Dessutom så identifierades mönster i de metaboliska profilerna bland fentanyl och fentanylanaloger. Dessa mönster kan användas för att förbättra predikteringen av metaboliter för andra nuvarande och kommande fentanylanaloger. Dessa resultat samt de utvecklade syntesvägarna kan nyttjas i framställningen av referenssubstanser i syfte att användas som biomarkörer för att i urin kunna detektera drogmissbruk. Referenssubstanserna kan även användas för att studera metaboliternas farmakologiska egenskaper vilket kan leda till en djupare förståelse kring toxiciteten hos modersubstanserna.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book The American Psychiatric Publishing Textbook of Substance Abuse Treatment written by Marc Galanter and published by American Psychiatric Pub. This book was released on 2015-04-01 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other text available today offers what The American Psychiatric Publishing Textbook of Substance Abuse Treatment can: completely updated treatment information on a broad range of substance use disorders that is consistent with the new DSM-5 classification and thus reflective of how psychiatry is practiced today. Designed for researchers and mental health professionals ranging from trainee to licensed practitioner, the book is also appropriate for a diverse array of rehabilitation settings, from inpatient to community-based treatment. Full coverage is provided on 12-step programs, as well, including the latest outcomes research. Much of the material is new to this edition: A chapter has been added on science in the treatment of substance abuse, in which the authors discuss the history of scientific intervention in substance abuse and explore what happens to the brain when addicting drugs are consumed, review animal models and imaging techniques, and discuss current progress in the science of addiction. Chapters have been added on screening and brief intervention, reflecting the development of brief screening tools and research on the efficacy of interventions, and the role of "recovery" in chronic care disease management -- specifically what the treatment models for alcohol dependence and for diabetes can effectively borrow from each other. A new chapter focuses on the treatment of alcohol intoxication and withdrawal -- the first steps in treatment of alcohol use disorder. Two chapters on marijuana -- one on the neurobiology and one addressing treatment have been added. Given the accelerating trend toward decriminalization and legalization of this substance, clinicians will find this information of increasing importance. The section on substance use issues among gay men and lesbians has been expanded to include bisexual and transgender people in recognition of increased diversity among the population. Well-structured, with topics that follow logically and many practical, treatment-oriented features, such as quick reference tables and lists of recommended readings, The American Psychiatric Publishing Textbook of Substance Abuse Treatment is a classic that will enhance the education and practice of clinicians.

Download or read book Synthetic Cathinones written by Jolanta B. Zawilska and published by Springer. This book was released on 2018-04-16 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, and particularly during the recent five years, a rapidly increasing number of novel psychoactive substance (NPSs), often marketed as “designer drugs”, “legal highs”, “herbal highs”, “research or intermediate chemicals” and “laboratory reagents”, has appeared on the drug market in an effort to bypass controlled substance legislation. NPSs encompass a wide range of different compounds and drug classes but had been dominated by synthetic cannabinomimetics and psychostimulatory synthetic cathinones, so-called β-keto amphetamines. Compounds from the later class were first detected in Europe in 2004, and since then 103 new cathinones have been identified and reported to the European Monitoring Centre for Drugs and Drug Addiction, with 57 during the last two years. Synthetic cathinones – novel addictive and stimulatory psychoactive substances is the first publication of this kind that provides readers with background on chemical structures, detection, prevalence and motivation of use of the very popular group of NPSs. This book also presents comprehensive overview of the mechanisms of action, pharmacological activity, and main metabolic pathways of synthetic cathinones, followed by a detailed discussion of the acute and chronic toxicity associated with the use of these substances. Written by international experts in the field, this multi-authored book is a valuable reference not only for scientists, clinicians and academics, but also for readers representing different professional background who are involved in educational-prophylactic activities directed to harm reduction of psychoactive compounds.
