Using the endogenous cannabinoid receptor agonist anandamide, the synthetic agonist CP 55940 [[1alpha,2beta(R)5alpha]-(-)-5-(1,1-dimethylheptyl+ ++)-2-[5-hydroxy-2-(3-hydroxypropyl)cyclohexyl]phenol], and the specific antagonist SR 141716
The endocannabinoids anandamide and 2-arachidonyl glycerol (2-AG) bind to G protein-coupled central and peripheral cannabinoid receptors CB1 and CB2, respectively. Due to the relatively high expression of the CB2 isotype on peripheral immune cells, it has been hypothesized that this receptor
There has been a worldwide proliferation of synthetic cannabinoids that have become marketed as legal alternatives to cannabis (marijuana). Unfortunately, there is a dearth of information about the pharmacological effects of many of these emerging synthetic cannabinoids (ESCs), which presents a
The recently discovered endogenous agonist for the cannabinoid receptor, anandamide (arachidonylethanolamide), can be formed enzymatically by the condensation of arachidonic acid with ethanolamine. 5Z,8Z,11Z-Eicosatrienoic acid (mead acid) has been found to substitute for arachidonic acid in the
1. The present study investigated the binding characteristics of various ligands to cannabinoid CB(1) receptors in human neocortex and amygdala. In addition, the functionality of CB(1) receptors in the human neocortex was assessed by examining the effects of CB(1) receptor ligands on evoked
The cannabinoid receptor 1 (CB1) cannabinoid receptor is an essential component of the cannabinergic system. It has been recognized as a therapeutic target for treating numerous diseases and is currently receiving considerable attention by the pharmaceutical community. Target-based drug design,
The cannabinoid 1 receptor (CB1R) is one of the most abundant G protein-coupled receptors (GPCRs) in the central nervous system. CB1R involvement in multiple physiological processes, especially neurotransmitter release and synaptic function, has made this GPCR a prime drug discovery target, and
Adenosine A1 and cannabinoid CB1 receptors are highly expressed in hippocampus where they trigger similar transduction pathways. We investigated how the combined acute activation of A1 and CB1 receptors modulates cAMP accumulation in rat hippocampal slices. The CB1 agonist WIN55212-2 (0.3-30 μM)
Recent developments indicate that CB(2) receptor ligands have the potential to become therapeutically important. To explore this potential, it is necessary to develop compounds with high affinity for the CB(2) receptor. Very recently, we have identified the oxazinoquinoline carboxamides as a novel
Although primary neuronal cell cultures, usually obtained from embryonic or early postnatal rodents, have been used in vitro to study the neural cannabinoid signalling system, development of cell lines with neural properties exhibiting native expression of cannabinoid receptors is desirable. This
We have investigated the pharmacology of two central human cannabinoid receptor isoforms, designated CB1 and CB1A, stably expressed in Chinese hamster ovary cell lines, designated as CHO-CB1 and CHO-CB1A, respectively. In direct binding assays on isolated membranes the agonist [3H]CP 55,940 bound in
Both opioids and cannabinoids bind to G-protein-coupled receptors to inhibit adenylyl cyclase in neurons. These reactions were assayed in brain membranes, where maximal inhibitory activity occurred in the following regions: mu-opioid inhibition in rat thalamus, delta-opioid inhibition in rat
The chemical similarity between some synthetic agonists of vanilloid receptors, such as olvanil (N-vanillyl-cis-9-octadecenoamide), and the 'endocannabinoid' anandamide (arachidonoyl-ethanolamide, AEA), suggests possible interactions between the cannabinoid and vanilloid signalling systems. Here we
We sought to examine the involvement of central cannabinoid CB2 receptor activation in modulating mechanical allodynia in a mouse model of neuropathic pain. JWH133 was demonstrated to be a selective cannabinoid CB2 receptor agonist in mice, reducing forskolin-stimulated cAMP production in CHO cells
We document in vitro and in vivo effects of a novel, selective cannabinoid CB(1) receptor inverse agonist, Imidazole 24b (5-(4-chlorophenyl)-N-cyclohexyl-4-(2,4-dichlorophenyl)-1-methyl-imidazole-2-carboxamide). The in vitro binding affinity of Imidazole 24b for recombinant human and rat CB(1)
