carrageenan/cannabis

The in vivo effect of inhibitors of fatty acid amide hydrolase (FAAH) upon oedema volume and FAAH activity was evaluated in the carrageenan induced hind paw inflammation model in the mouse. Oedema was measured at two time points, 2 and 4 h, after intraplantar injection of carrageenan to

Cannabidiol, the major non-psychoactive component of marijuana, has various pharmacological actions of clinical interest. It is reportedly effective as an anti-inflammatory and anti-arthritic in murine collagen-induced arthritis. The present study examined the anti-inflammatory and anti-hyperalgesic

Cannabinoids classically act via CB₁ and CB₂ receptors to modulate nociception; however, recent findings suggest that some cannabinoids bind to atypical receptors. One such receptor is GPR55 which is activated by the abnormal cannabidiol analogue O-1602. This study investigated whether the synthetic

OBJECTIVE Effects of locally administered agonists and antagonists for cannabinoid CB(1) and CB(2) receptors on mechanical and thermal hypersensitivity were compared after the establishment of chronic inflammation. METHODS Carrageenan was administered unilaterally to the rat hindpaw on day 1.

Activation of cannabinoid CB(2) receptors attenuates thermal nociception in untreated animals while failing to produce centrally mediated effects such as hypothermia and catalepsy [Pain 93 (2001) 239]. The present study was conducted to test the hypothesis that activation of CB(2) in the periphery

Although the N-arachidonoyl ethanolamine (anandamide) binds to cannabinoid receptors and has been implicated in the suppression of pain, its rapid catabolism in vivo by fatty acid amide hydrolase (FAAH) has presented a challenge in investigating the physiological functions of this endogenous

SAR studies were performed on a series of 2-arylamido-5,7-dihydro-4H-thieno[2,3-c]pyran-3-carboxamide derivatives as cannabinoid receptor agonists. Starting from a HTS hit both potency and selectivity could be improved. Modifications to the thiophene fusion and C-3 amides were studied. A

The CB1/CB2 receptor agonist WIN 55212-2 (0.75 mg/kg, i.v.) caused a significant reduction in neurogenic plasma extravasation induced by electrical stimulation of the saphenous nerve in anesthetized rats; WIN 55212-2 at 2.5-10 mg/kg, s.c., also produced a significant reduction in the

Effects of the CB2-selective cannabinoid agonist AM1241 on activity evoked in spinal wide dynamic range (WDR) neurons by transcutaneous electrical stimulation were evaluated in urethane-anesthetized rats. Recordings were obtained in both the absence and the presence of carrageenan inflammation.

Pharmacological evidence indicated a functional interaction between neuropeptide FF (NPFF) and cannabinoid systems, and the cannabinoids combined with the NPFF receptor agonist neuropeptide VF (NPVF) produced antinociception without tolerance. In the present study, VF-13, a chimeric peptide

Spinally administered cannabinoid receptor agonists are anti-nociceptive in a variety of models of acute and persistent pain. The present study investigated the effects of activation of spinal cannabinoid CB(1) receptors on mechanically evoked responses of spinal neurones in acute and inflammatory

3-[2-Cyano-3-(trifluoromethyl)phenoxy]phenyl-4,4,4-trifluoro-1-butanesulfonate (BAY 59-3074) is a novel, selective cannabinoid CB(1)/CB(2) receptor ligand (K(i) = 55.4, 48.3, and 45.5 nM at rat and human cannabinoid CB(1) and human CB(2) receptors, respectively), with partial agonist properties at

Peltatoside is a natural compound isolated from leaves of Annona crassiflora Mart., a plant widely used in folk medicine. This substance is an analogue of quercetin, a flavonoid extensively studied because of its diverse biological activities, including analgesic effects. Besides, a previous study

The present studies were conducted to test the hypothesis that systemically inactive doses of cannabinoids suppress inflammation-evoked neuronal activity in vivo via a peripheral mechanism. We examined peripheral cannabinoid modulation of spinal Fos protein expression, a marker of neuronal activity,

Pain associated with cancer and chronic musculoskeletal disorders can be difficult to control. We used murine models of cancer and inflammatory muscle pain to examine whether the cannabinoid receptor agonist WIN55,212-2 reduces hyperalgesia originating in deep tissues. C3H/He mice were anesthetized
