Therapeutic potential of cannabinoid medicines Philip J. Robson Drug and Testing Analysis, 2014 Doi : 10.1002/dta.1529 Cannabis was extensively used as amedicine throughout the developed world in the nineteenth century but went into decline early in the twentieth century ahead of its emergence as the most widely used illicit recreational drug later that century. Recent advances in cannabinoid pharmacology alongside the discovery of the endocannabinoid system (ECS) have re-ignited interest in cannabis-based medicines. The ECS has emerged as an important physiological system and plausible target for new medicines. Its receptors and endogenous ligands play a vital modulatory role in diverse functions including immune response, [...]
Lire la suite2-Linoleoylglycerol Is a Partial Agonist of the Human Cannabinoid Type 1 Receptor that Can Suppress 2-Arachidonolyglycerol and Anandamide Activity Leanne Lu, Gareth Williams, and Patrick Doherty* Cannabis and Cannabinoid Research, 2019 Doi : 10.1089/can.2019.0030 Abstract Introduction : The cannabinoid type 1 (CB1) receptor and cannabinoid type 2 (CB2) receptor are widely expressed in the body and anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are their best characterized endogenous ligands. The diacylglycerol lipases (diacylglycerol lipase alpha and diacylglycerol lipase beta) not only synthesize essentially all the 2-AG in the body but also generate other monoacylglycerols, including 2- linoleoylglycerol (2-LG). This lipid has been proposed to modulate endocannabinoid (eCB) [...]

However, whether CB1R levels are altered in the early stages of psychosis and whether they are linked to cognitive function or symptom severity remain unknown. OBJECTIVE To investigate CB1R availability in first-episode psychosis (FEP) without the [...]

Renata Androvicova, Jiri Horacek, Tibor Stark, Filippo Drago, Vincenzo Micale Pharmacological Research, 2017, 115, 200–208 http://dx.doi.org/10.1016/j.phrs.2016.11.021 a b s t r a c t The endocannabinoid system (ECS), which is composed of the cannabinoid receptors types 1 and 2 (CB1 and CB2) for marijuana’s psychoactive ingredient 9-tetrahydrocannabinol (9-THC), the endogenous ligands (AEA and 2-AG) and the enzymatic systems involved in their biosynthesis and degradation, recently emerged as important modulator of emotional and non-emotional behaviors. For centuries, in addition to its recreational actions, several contradictory claims regarding the effects of Cannabis use in sexual functioning and behavior [...]

Doi : 10.3928/02793695-20190813-01 ABSTRACT The increasing public acceptance of cannabis and the proliferation of cannabis products in the market-place has coincided with more patients using the drug as a substitute for psychiatric medications or as an adjunctive treatment modality for psychiatric conditions, despite limited evidence of efficacy. With a goal of furthering harm-reduction eff orts in psychiatric nursing, the current article reviews the fundamentals of the endocannabinoid system in humans and the exogenous phytocannabinoids that act on this regulatory [...]

Doi : 10.2174/1574889809666140307115532 Abstract Increasing evidence suggests a close relationship between the endocannabinoid system and schizophrenia. The endocannabinoid system comprises of two G protein-coupled receptors (the cannabinoid receptors 1 and 2 [CB1 and CB2] for marijuana's psychoactive principle Δ(9)-tetrahydro-cannabinol), their endogenous small lipid ligands (namely anandamide [AEA] and 2-arachidonoyl-glycerol [2-AG], also known as endocannabinoids), and proteins for endocannabinoid biosynthesis and degradation. It has been suggested to be a pro-homeostatic and pleiotropic signalling system activated in a time- and tissue-specific manner during [...]

O’Sullivan Frontiers in Pharmacology, 26 November 2018 https://doi.org/10.3389/fphar.2018.01365 Background : Cannabidiol is being pursued as a therapeutic treatment for multiple conditions, usually by oral delivery. Animal studies suggest oral bioavailability is low, but literature in humans is not sufficient. The aim of this review was to collate published data in this area. Methods : A systematic search of PubMed and EMBASE (including MEDLINE) was conducted to retrieve all articles reporting pharmacokinetic data of CBD in humans. Results : Of 792 articles retireved, 24 included [...]
