The Endocannabinoid System and its Modulation by Phytocannabinoids Vincenzo Di Marzo & Fabiana Piscitelli Neurotherapeutics, 2015, 12, 692–698 DOI 10.1007/s13311-015-0374-6 Abstract : The endocannabinoid system is currently defined as the ensemble of the two 7-transmembrane-domain and G protein-coupled receptors for Δ9-tetrahydrocannabinol (but not for most other plant cannabinoids or phytocannabinoids)—cannabinoid receptor type-1 (CB1R) and cannabinoid receptor type-2 (CB2R); their two most studied endogenous ligands, the “endocannabinoids” N-arachidonoyl-ethanolamine (anandamide) and 2-arachidonoylglycerol (2-AG); and the enzymes responsible for endocannabinoid metabolism. However, anandamide and 2-AG, and also the phytocannabinoids, have more molecular targets than just CB1R and CB2R. Furthermore, the endocannabinoids, like most other lipid mediators, have more [...]

This chapter is distributed under the terms of the Creative Commons; Attribution License (http://creativecommons.org/licenses/by/3.0), Abstract On October 17, 2018, Canada became the first G20 nation to legalize the use of Cannabis sativa for both medicinal and recreational purposes. This change in legislation and end of prohibition are indicative of a larger global movement to understand Cannabis—and the bioactive chemicals present within Cannabis known as the cannabinoids—for its potential biomedical uses, harms, and economic values. Currently, interest in Cannabis and cannabinoid research is surging as the many [...]

Walker, Mahmoud A. ElSohly, Bill J. Gurley and Igor Koturbash Molecules, 2019, 24, 1694 doi : 10.3390/molecules24091694 Abstract : The goal of this study was to investigate Cannabidiol (CBD) hepatotoxicity in 8-week-old male B6C3F1 mice. Animals were gavaged with either 0, 246, 738, or 2460 mg/kg of CBD (acute toxicity, 24 h) or with daily doses of 0, 61.5, 184.5, or 615 mg/kg for 10 days (sub-acute toxicity). These doses were the allometrically scaled mouse equivalent doses (MED) [...]

Bertoglio, Francisco S. Guimarães and Carl W. Stevenson British Journal of Pharmacology, 2017, 174, 3242–3256 DOI : 10.1111/bph.13724 Abstract Learning to associate cues or contexts with potential threats or rewards is adaptive and enhances survival. Both aversive and appetitive memories are therefore powerful drivers of behaviour, but the inappropriate expression of conditioned responding to fear- and drug-related stimuli can develop into anxiety-related and substance abuse disorders respectively. These disorders are associated with abnormally persistent emotionalmemories and inadequate treatment, often leading to symptom relapse. [...]

Lire la suiteDoes cannabidiol protect against adverse psychological effects of THC ? Raymond J. M. Niesink and Margriet W. van Laar Frontiers in Psychiatry, 2013, 4, 130 doi : 10.3389/fpsyt.2013.00130. Abstract The recreational use of cannabis can have persistent adverse effects on mental health. Delta 9-tetrahydro-cannabinol (THC) is the main psychoactive constituent of cannabis, and most, if not all, of the effects associated with the use of cannabis are caused by THC. Recent studies have suggested a possible protective effect of another cannabinoid, cannabidiol (CBD). A literature search was performed in the bibliographic databases PubMed, PsycINFO, andWeb of Science using the keyword “cannabidiol.” After removing duplicate entries, [...]

Kotra Cannabis and Cannabinoid Research, Volume X, Number X, 2019 Mary Ann Liebert, Inc. DOI: 10.1089/can.2018.0067 Abstract Introduction : Phytocannabinoids, characteristic compounds produced by medical cannabis, interact with cannabinoid (CB) receptors (CB1 and CB2) as well as other receptor systems to exhibit their corresponding pharmacological effects. In their natural form, CBs such as D9-tetrahydrocannabinolic acid and cannabidiolic acid are inactive at these receptors, while their decarboxylated forms (D9 tetrahydrocannabinol and cannabidiol, respectively) are potent ligands at CB receptors. Thus, extraction and processing [...]

INTRODUCTION Both phytocannabinoids, the psychoactive compounds naturally present in the cannabis plant, and synthetic cannabinoids (SCs; also known as synthetic cannabimimetics) exert their effects through alteration of the endocannabinoid system (Szabo, 2014). There are at least 104 different phytocannabinoids in cannabis, and their combination contributes to the psychoactive effects of cannabis (ElSohly & Gul, 2014). In 1967, the United States [...]
