The present study describes the implementation of comparative molecular field analysis (CoMFA) to develop two 3D-QSAR (quantitative structure-activity relationship) models (CoMFA models 1 and 2) of the cannabimimetic (aminoalkyl)indoles (AAIs) for CB1 cannabinoid receptor binding affinity, based on pKi values measured using radioligand binding assays that displace two different agonist ligands,...
Cannabinoids, acting through the CB1 cannabinoid receptor (CB1R), protect the brain against ischemia and related forms of injury. This may involve inhibiting the neurotoxicity of endogenous excitatory amino acids and downstream effectors, such as nitric oxide (NO). Cannabinoids also stimulate neurogenesis in the adult brain through activation of CB1R. Because NO has been implicated in neurogene...
ackground: Recent studies have raised concerns about subtle long-lasting neurobiological changes that might be triggered by xposure to Cannabis derivatives, especially in a critical phase of brain maturation, such as puberty. The mesolimbic dopamine (DA) ystem, involved in the processing of drug-induced reward, is a locus of action of cannabinoids and endocannabinoids. Thus, we ompared the effe...
Although cannabinoids are efficacious in laboratory animal models of inflammatory pain, their established cannabimimetic actions diminish enthusiasm for their therapeutic development. Conversely, fatty acid amide hydrolase (FAAH), the chief catabolic enzyme regulating the endogenous cannabinoid N-arachidonoylethanolamine (anandamide), has emerged as an attractive target for treating pain and ot...
introduction: previous studies have shown that cannabinoidergic system is involved in anxiety. however, there are controversial reports in the experimental studies. the aim of this study is to evaluate the effect of pharmacological stimulation or blocking of cb1 receptors and inhibition of endocannabinoid degradation in anxiety like behavior in elevated plus-maze (epm) test in rat. the epm is o...

Previous studies had shown that the amplification factors for cannabinoid receptors, defined as the number of total G proteins activated per occupied receptor, differs between several rat brain regions. In this study, we sought to determine which specific Gi/Goa subunits were activated by CB1 receptors in several rat brain regions and if this coupling might explain the regional differences in r...
