The 1H-NMR spectra in deuteriochloroform of racemic and optically pure (trans)-6a,7,10,10a-tetrahydro-1-hydroxy-6,6-dimethyl-3-pentyl-6H-dibenz o [b,d]pyran-9(8H)-one (1) are nonsuperimposable, while nonracemic mixtures of the (+)- and (-)-isomers show two sets of signals for the phenolic and
A series of quinolinyl and isoquinolinyl phenyl ketones was synthesized and their CB(2) receptor-dependent G-protein activities were determined using the [(35)S]GTPgammaS binding assay. Both quinoline and isoquinoline derivatives exhibited similar CB(2) receptor agonist activity, the most potent
A series of potent indol-3-yl-tetramethylcyclopropyl ketones have been prepared as CB 2 cannabinoid receptor ligands. Two unsubstituted indoles ( 5, 32) were the starting points for an investigation of the effect of indole ring substitutions on CB 2 and CB 1 binding affinities and activity in a CB 2
Synthetic indole-derived cannabinoids have become commonly used recreational drugs and continue to be abused despite their adverse consequences. As compounds that were identified early in the epidemic (e.g., naphthoylindoles) have become legally banned, new compounds have appeared on the drug
Several 3-acylindoles with high affinity for the CB(2) cannabinoid receptor and selectivity over the CB(1) receptor have been prepared. A variety of 3-acyl substituents were investigated, and the tetramethylcyclopropyl group was found to lead to high affinity CB(2) agonists (5, 16). Substitution at
Being marketed as "legal" smoking blends or mixtures, synthetic cannabinoids are abused widely owing to its cannabis-like effect. Due to the rapid introduction of new generation analogues of synthetic cannabinoids to escape from legislative/judicial control, the investigation of the metabolic
2-Arachidonoylglycerol (2-AG (1)) is an endogenous ligand for the cannabinoid receptors (CB1 and CB2). There is growing evidence that 2-arachidonoylglycerol plays important physiological and pathophysiological roles in various mammalian tissues and cells, though the details remain to be clarified.
Microorganisms were screened for their ability to modify 2 synthetic cannabinoid substrates (I and II). Structure analyses revealed that microorganisms transformed the substrates by (a) primary oxidation of the side chain, beta-oxidation of the side chain, ketone formation on the side chain or
A recent cannabis use survey revealed that 60% of cannabis users rely on smelling the flower to select their cannabis. Olfactory indicators in plants include volatile compounds, principally represented by the terpenoid fraction. Currently, medicinal- and adult-use cannabis is marketed in the United
The present review summarizes the recent work carried out by our group on the link between signal transduction pathways and metabolic regulation systems as affected by cannabinoids. In cells such as astrocytes and lymphocytes, which express cannabinoid receptors, physiologically relevant doses of
Synthesis of an antagonist, SR141716A, that selectively binds to brain cannabinoid (CB(1)) receptors without producing cannabimimetic activity in vivo, suggests that recognition and activation of cannabinoid receptors are separable events. In the present study, a series of SR141716A analogs were
The novel endogenous cannabinoid 2-arachidonoylglycerol (2-AG) was rapidly inactivated by intact rat basophilic leukaemia (RBL-2H3) and mouse neuroblastoma (N18TG2) cells through diffusion/hydrolysis/reacylation processes. The hydrolysis of 2-AG was inhibited by typical esterase inhibitors and by
Previous studies of the structure-activity relationships (SAR) for binding of a series of AC-bicyclic cannabinoid structures to the cannabinoid receptors in rat brain (believed to comprise the CB1 subtype) demonstrated the importance of the A-ring aryl C-3 side chain and phenolic hydroxyl
The central CB2 receptor represents a promising target for the treatment of neuroinflammatory diseases as CB2 activation mediates anti-inflammatory effects. Recently, the F-18 labeled PET radiotracer [18F]7a was reported, which shows high CB2 affinity and high selectivity over the CB1 subtype but
Indazole carboxamide synthetic cannabinoids remain the most prevalent subclass of new psychoactive substances (NPS) reported internationally. However, the metabolic and pharmacological properties of many of these compounds remain unknown. Elucidating these characteristics allows members of the
