BACKGROUND AND PURPOSE Cannabidiol (CBD) and Δ(9) -tetrahydrocannabinol (THC) interact with transient receptor potential (TRP) channels and enzymes of the endocannabinoid system. EXPERIMENTAL APPROACH The effects of 11 pure cannabinoids and botanical extracts [botanical drug substance (BDS)] from Cannabis varieties selected to contain a more abundant(More)
The cannabinoid CB2 receptor, which is activated by the endocannabinoid 2-arachidonoyl-glycerol (2-AG), protects striatal neurons from apoptotic death caused by the local administration of malonate, a rat model of Huntington's disease (HD). In the present study, we investigated whether endocannabinoids provide tonic neuroprotection in this HD model, by(More)
The endocannabinoid system (ECS) represents one of the major determinants of metabolic disorders. We investigated potential changes in the endogenous levels of anandamide (AEA), 2-arachidonoylglycerol (2-AG), N-oleoylethanolamine (OEA) and N-palmitoylethanolamine (PEA) in some peripheral organs and tissues of obese Zucker(fa/fa) and lean Zucker(fa/+) rats(More)
The complex etiology of Alzheimer's disease prompts scientists to develop multi-target strategies to combat causes and symptoms. In line with this modern paradigm and as a follow-up to our previous studies, we designed and synthesized a focused collection of new 2-arylbenzofurans and evaluated their biological properties towards specific targets involved in(More)
The waxy fraction from the variety Carma of fiber hemp (Cannabis sativa) afforded the unusual cannabinoid 4, identified as the farnesyl prenylogue of cannabigerol (CBG, 1) on the basis of its spectroscopic properties. A comparative study of the profile of 4 and 1 toward metabotropic (CB1, CB2) and ionotropic (TRPV1, TRPV2, TRPM8, TRPA1) targets of(More)
BACKGROUND AND PURPOSE Prostamides are lipid mediators formed by COX-2-catalysed oxidation of the endocannabinoid anandamide and eliciting effects often opposed to those caused by anandamide. Prostamides may be formed when hydrolysis of anandamide by fatty acid amide hydrolase (FAAH) is physiologically, pathologically or pharmacologically decreased. Thus,(More)
To investigate if certain acylethanolamides bind to both cannabinoid (CB(1) and CB(2)) and vanilloid TRPV1 receptors because of their conformational flexibility, we introduced a methylene lock on their ethanolamine "head", thereby generating a cyclopropane ring with two stereogenic centers and chiral cis/trans diastereomers with different topology of(More)
Biosynthesis Inhibition: O-5596, a new inhibitor of the biosynthesis of the endocannabinoid, 2-arachidonoylglycerol, was synthesized and found to be potent (IC(50)=100 nM) and selective versus other proteins and enzymes of the endocannabinoid system in vitro and active in vivo at reducing food intake in mice.
BACKGROUND AND PURPOSE The development of potent and selective inhibitors of the biosynthesis of the endocannabinoid 2-arachidonoylglycerol (2-AG) via DAG lipases (DAGL) α and β is just starting to be considered as a novel and promising source of pharmaceuticals for the treatment of disorders that might benefit from a reduction in endocannabinoid tone, such(More)
CB2 receptor belongs to the large family of G-protein coupled receptors (GPCRs) controlling a wide variety of signal transduction. The recent crystallographic determination of human β2 adrenoreceptor and its high sequence similarity with human CB2 receptor (hCB2) prompted us to compute a theoretical model of hCB2 based also on β2 adrenoreceptor coordinates.(More)
