Role of the endogenous cannabinoid system in nicotine addiction : novel insights, Islam Hany Gamaleddin et al., 2015

Role of the endogenous cannabinoid system in nicotine addiction : novel insights Islam Hany Gamaleddin, Jose M.Trigo, Aliou B. Gueye, Alexander Zvonok, Alexandros Makriyannis, Steven R. Goldberg and Bernard Le Foll Frontiers in Psychiatry, 2015, Vol 6, Article 41, 1-12. doi : 10.3389/fpsyt.2015.00041 Several lines of evidence have shown that the endogenous cannabinoids are implicated in several neuropsychiatric diseases. Notably, preclinical and human clinical studies have shown a pivotal role of the cannabinoid system in nicotine addiction. The CB1 receptor inverse agonist/antagonist rimonabant (also known as SR141716)was effective to decrease nicotine-taking and nicotine-seeking in rodents, as well as the elevation of dopamine induced by [...]

Cannabinomimetric Lipids : From Natural Extract to Artificial Synthesis, Ya-Ru Gao & Yong-Qiang Wang, 2018

Cannabinomimetric Lipids : From Natural Extract to Artificial Synthesis Ya-Ru Gao, Yong-Qiang Wang Natural Products and Bioprospecting, 2018, 8, 1–21 doi : 10.1007/s13659-017-0151-9 Abstract Endocannabinoid system is related with various physiological and cognitive processes including fertility, pregnancy, during pre- and postnatal development, pain-sensation, mood, appetite, and memory. In the latest decades, an important milestone concerning the endocannabinoid system was the discovery of the existence of the cannabinoid receptors CB1 and CB2. Anandamide was the first reported endogenous metabolite, which adjusted the release of some neurotransmitters through binding to the CB1 or CB2 receptors. Then a series of cannabinomimetric lipids were extracted from marine organisms, which [...]

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection, Sanja Zivovinovic, et al., 2018

Determination of cannabinoids in Cannabis sativa L. samples for recreational, medical, and forensic purposes by reversed-phase liquid chromatography-ultraviolet detection Sanja Zivovinovic, Ruth Alder, Martina D. Allenspach and Christian Steuer Journal of Analytical Science and Technology, 2018, 9, 27, 1-10 doi : 10.1186/s40543-018-0159-8   Abstract Background : Currently, an increasing demand of cannabis-derived products for recreational and medical use is observed. Therefore, the reliable and fast quantification of cannabinoids in hemp samples is essential for the control of product from Cannabis sativa, L. strains. In general, gas chromatography (GC) is the method of choice for the quantification of cannabinoids whereas this method is time consuming and the [...]

Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity, Swapnali Chetia & Gaurab Borah, 2020

Δ 9‑Tetrahydrocannabinol Toxicity and Validation of Cannabidiol on Brain Dopamine Levels : An Assessment on Cannabis Duplicity Swapnali Chetia · Gaurab Borah Natural Products and Bioprospecting, 2020, 10, 285–296 doi : 10.1007/s13659-020-00263-z   Abstract Δ9-tetrahydrocannabinol (THC) of cannabis is the main psychoactive component which is a global significant concern to human health. Evaluation on THC reported its drastic effect on the brain dopaminergic (DAergic) system stimulating mesolimbic DA containing neurons thereby increasing the level of striatal DA. Cannabidiol (CBD), with its anxiolytic and anti-psychotic property, is potent to ameliorate the THC-induced DAergic variations. Legal authorization of cannabis use and its analogs in most countries led to [...]

The role of cannabinoid transmission in emotional memory formation : implications for addiction and schizophrenia, Huibing Tan et al., 2014

The role of cannabinoid transmission in emotional memory formation: implications for addiction and schizophrenia Huibing Tan, Tasha Ahmad, Michael Loureiro, Jordan Zunder and Steven R. Laviolette Frontiers in Psychiatry, 2014,Vol 5, Article 73, 1-12 doi : 10.3389/fpsyt.2014.00073   Emerging evidence from both basic and clinical research demonstrates an important role for endo-cannabinoid (ECB) signaling in the processing of emotionally salient information, learning, and memory. Cannabinoid transmission within neural circuits involved in emotional processing has been shown to modulate the acquisition, recall, and extinction of emotionally salient memories and importantly, can strongly modulate the emotional salience of incoming sensory information. Two neural regions in particular, the [...]

Recent Advances in the Neuropsychopharmacology of Serotonergic Hallucinogens, Adam L. Halberstadt, 2015

Recent Advances in the Neuropsychopharmacology of Serotonergic Hallucinogens Adam L. Halberstadt Behavioral Brain Research, 2015, 15, 277, 99–120. doi : 10.1016/j.bbr.2014.07.016   Abstract Serotonergic hallucinogens, such as (+)-lysergic acid diethylamide, psilocybin, and mescaline, are somewhat enigmatic substances. Although these drugs are derived from multiple chemical families, they all produce remarkably similar effects in animals and humans, and they show cross-tolerance. This article reviews the evidence demonstrating the serotonin 5-HT2A receptor is the primary site of hallucinogen action. The 5-HT2A receptor is responsible for mediating the effects of hallucinogens in human subjects, as well as in animal behavioral paradigms such as drug discrimination, head twitch response, prepulse [...]

What Can We Learn About Schizophrenia From Studying the Human Model, Drug-Induced Psychosis ?, Robin M. Murray et al., 2013

What Can We Learn About Schizophrenia From Studying the Human Model, Drug-Induced Psychosis ? Robin M. Murray, Alessandra Paparelli, Paul D. Morrison, Arianna Marconi, and Marta Di Forti American Journal of Medical Genetics, Part B, 2013, 162B, 661–670. Doi : 10.1002/ajmg.b.32177   When drug-induced psychoses were first identified in the mid- 20th century, schizophrenia was considered a discrete disease with a likely genetic cause. Consequently, drug-induced psychoses were not considered central to understanding schizophrenia as they were thought to be phenocopies rather than examples of the illness secondary to a particular known cause. However, now that we know that schizophrenia is a clinical syndrome with [...]
