Extractions of Medical Cannabis Cultivars and the Role of Decarboxylation in Optimal Receptor Responses Melissa M. Lewis-Bakker, Yi Yang, Rupali Vyawahare, and Lakshmi P. 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 [...]

Lire la suiteMedicinal Use of Synthetic Cannabinoids—a Mini Review P. Muralidhar Reddy, Nancy Maurya & Bharath Kumar Velmurugan Current Pharmacology Reports, 2019 https://doi.org/10.1007/s40495-018-0165-y Abstract Purpose of Review : This review gives an overview of the medicinal uses of synthetic cannabinoids and other related aspects on the basis of recent as well as earlier studies that the authors considered relevant to the context and scope of the review. Recent Findings Synthetic cannabinoids are laboratory synthesized products eliciting effects way more than their natural counterparts. These compounds are more potent in generating intoxicating effects and are also difficult to be detected in conventional screening tests. Their clinical side effects are also more pronounced than [...]
Lire la suiteREVIEW : Cannabidiol – Recent Advances Raphael Mechoulam, Maximilian Petersa, Eric Murillo-Rodriguez and Lumïr O. Hanus Chemistry and Biodiversity, 2007, 4, 1678-1692. The aim of this review is to present some of the recent publications on cannabidiol (CBD; 2), a major non-psychoactive constituent of Cannabis, and to give a general overview. Special emphasis is laid on biochemical and pharmacological advances, and on novel mechanisms recently put forward, to shed light on some of the pharmacological effects that can possibly be rationalized through these mechanisms. The plethora of positive pharmacological effects observed with CBD make this compound a highly attractive therapeutic entity. Contents 1. Introduction 2. Mechanisms of Cannabidiol Action 2.1. Cannabidiol: an [...]
Lire la suiteLes Phyto-cannabinoïdes Non-psychotropes* : Les nouvelles Opportunités d'une plante ancienne.(*NdT : non-stupéfiants) Angelo A. Izzo, Francesca Borrelli, Raffaele Capasso, Vincenzo Di Marzo and Raphael Mechoulam Trends in Pharmacological Sciences - CELL Press, 2009, 30, 10, 515-27. doi: 10.1016/j.tips.2009.07.006. Le Δ9-tetrahydrocannabinol (Δ9THC) se lie aux récepteurs endocannabinoïdes (CB1 et CB2) qui sont activés par les cannabinoïdes endogènes (endocannabinoïdes) et qui sont impliqués dans une large gamme de processus physiopathologiques (exemple: modulation de la libération de neurotransmetteurs, régulation de la perception de la douleur, régulation des fonctions cardiovasculaires, gastro-intestinales et hépatiques). Les effets psychotropes bien connus du Δ9THC qui sont véhiculés par l'activation des récepteurs CB1 [...]

C : Springer Nature Switzerland AG Abstract : At present, clinical interest in the plant-derived cannabinoid compound cannabidiol (CBD) is rising exponentially, since it displays multiple therapeutic properties. In addition, CBD can counteract the undesirable effects of the psychoactive cannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) that hinder clinical development of cannabis-based therapies. Despite this attention, the mechanisms of CBD action and its interaction with Δ9-THC are still not completely elucidated. Here, by combining in vivo [...]

Journal of Neurotrauma, Nov 2018, 36, 1-11 DOI: 10.1089/neu.2018.6063 Abstract : Cannabis is one of the most widely used plant drugs in the world today. In spite of the large number of scientific reports on medical marijuana, there still exists much controversy surrounding its use and the potential for abuse due to the undesirable psychotropic effects. However, recent developments in medicinal chemistry of novel non-psychoactive synthetic cannabinoids have indicated that it is possible to separate some of the therapeutic effects [...]

Holmes, Neuroscience and Biobehavioral Reviews, 2017, 76, 56-66. https://doi.org/10.1016/j.neubiorev.2016.12.033 Abstract The endocannabinoid (eCB) system has attracted attention for its role in various behavioral and brain functions, and as a therapeutic target in neuropsychiatric disease states, including anxiety disorders and other conditions resulting from dysfunctional responses to stress. In this mini-review, we highlight components of the eCB system that offer potential ‘druggable’ targets for new anxiolytic medications, emphasizing some of the less well-discussed options. We discuss how selectively amplifying eCBs recruitment by interfering with eCB-degradation, via fatty [...]
