The diverse CB1 and CB2 receptor pharmacology of three plant cannabinoids : D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin, R.G. Pertwee, 2008

The diverse CB1 and CB2 receptor pharmacology of three plant cannabinoids : D9-tetrahydrocannabinol, cannabidiol and D9-tetrahydrocannabivarin Roger G. Pertwee British Journal of Pharmacology, 2008, 153, 199–215 doi:10.1038/sj.bjp.0707442   Cannabis sativa is the source of a unique set of compounds known collectively as plant cannabinoids or phytocannabinoids. This review focuses on the manner with which three of these compounds, (-)-trans-D9-tetrahydrocannabinol (D9-THC), (-)- cannabidiol (CBD) and (-)-trans-D9-tetrahydrocannabivarin (D9-THCV), interact with cannabinoid CB1 and CB2 receptors. D9-THC, the main psychotropic constituent of cannabis, is a CB1 and CB2 receptor partial agonist and in line with classical pharmacology, the responses it elicits appear to be strongly influenced both by [...]

Marijuana and the Cannabinoids Edited by Mahmoud A. ElSohly, PhD, Humana Press, Totowa, New Jersey, USA, 2007 www.humanapress.com 1. Cannabinoids. I. ElSohly, Mahmoud A. II. Series. [DNLM: 1. Cannabinoids. 2. Cannabis. QV 77.7 M33515 2006] QP801.C27M355 2006 615'.7827--dc22 333 pages, Preface Although primarily used today as one of the most prevalent illicit leisure drugs, the use of Cannabis sativa L., commonly referred to as marijuana, for medicinal purposes has been reported for more than 5000 years. Marijuana use has been shown to create numerous health problems, and, consequently, the expanding use beyond medical purposes into recreational use (abuse) resulted in control of the drug through international treaties. Much research has been [...]

Les cannabinoïdes dans l’Autisme, Christian Sueur, GRECC, juin 2019

Les cannabinoïdes dans l’Autisme : Dr Christian Sueur GRECC (Groupe de Recherches et D’Etudes Cliniques sur les Cannabinoïdes) Version actualisée juin 2019   L’autisme est une pathologie, ou plutôt un trouble majeur du développement psycho-neuro-développemental, à l’étiologie complexe et multifactorielle ; rentrent vraisemblablement en interaction, pour produire un trouble du spectre autistique, aussi bien des facteurs psychologique interactionnels précoces, qu’un terrain de fragilité ou de prédisposition génétique, à l’origine d’anomalies neurophysiologiques du développement de la connectique neuronale. Depuis près d’une vingtaine d’année, les cannabinoïdes représente progressivement une nouvelle voie d’approche thérapeutique des autismes les plus sévères.   Certains parents, surtout aux USA[1], ont adopté depuis le début [...]

Deconstructing Ecstasy : The Politics Of MDMA Research, Charles S. Grob, 2000

Deconstructing Ecstasy : The Politics Of MDMA Research Charles S. Grob Addiction Research, 2000, 8, 6, 549-588 http://dx.doi.org/10.3109/16066350008998989   What is Ecstasy? Defined by the New Webster’s Dictionary as a state of intense overpowering emotion, a condition of exultation or mental rapture induced by beauty, music, artistic creation or the contemplation of the divine, ecstasy derives etymologically from the ancient Greek ekstasis, which means flight of the soul from the body. The anthropologist, Mircea Eliade, who explored the roots of religious experience in his book Shamanism: Archaic Techniques of Ecstasy, has described the function of this intense state of mind among aboriginal peoples.

Changes in global and thalamic brain connectivity in LSD-induced altered states of consciousness are attributable to the 5- HT2A receptor, Katrin H. Preller, Franz X. Vollenweider et al., 2018

Changes in global and thalamic brain connectivity in LSD-induced altered states of consciousness are attributable to the 5- HT2A receptor Katrin H. Preller, Joshua B. Burt, Jie Lisa Ji, Charles Schleifer, Brendan D. Adkinson, Philipp Stampfli, Erich Seifritz, Grega Repovs, John H. Krystal, John D. Murray, Franz X. Vollenweider, Alan Anticevic eLife, 2018, 7, e35082. DOI: https://doi.org/10.7554/eLife.35082.001 Abstract Background : Lysergic acid diethylamide (LSD) has agonist activity at various serotonin (5-HT) and dopamine receptors. Despite the therapeutic and scientific interest in LSD, specific receptor  contributions to its neurobiological effects remain unknown. Methods : We therefore conducted a double-blind, randomized, counterbalanced, cross-over study (ClinicalTrials.gov, NCT02451072) during which [...]

The Endocannabinoid System and its Modulation by Phytocannabinoids, Vincenzo Di Marzo & Fabiana Piscitelli

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 [...]
