The present study examined whether descending noradrenergic and serotonergic systems mediate the antinociceptive effect of the prototypical cannabinoid, delta-9-tetrahydrocannabinol (delta 9-THC). Rats were administered vehicle or delta 9-THC (10 mg/kg, i.v.) and subsequently given an intrathecal

Agmatine-cannabinoid interactions are supported by the close association between cannabinoid CB(1) receptors and agmatine immunoreactive neurons and evidence that shared brain mechanisms underlie the pharmacological effects of agmatine and cannabinoid agonists. In the present study, we used the

The purpose of this study was to characterize the intraocular pressure (IOP) lowering activity and possible mechanism of action of the synthetic, non-psychotropic cannabinoid dexanabinol (HU-211) [(+)(3S,4S), 7-hydroxy-delta-6-tetrahydrocannabinol 1,1 dimethylheptyl], following intravenous (i.v.)

Functional interactions between cannabinoid and alpha-2 adrenergic systems in cognitive control in the medial prefrontal cortex (mPFC) seem possible. The present study evaluated the possible role of alpha-2 adrenoceptors of the prefrontal cortex on effect of arachidonylcyclopropylamide (ACPA), a

The noradrenergic system plays a critical role in the modulation of emotional state, primarily related to anxiety, arousal, and stress. Growing evidence suggests that the endocannabinoid system mediates stress responses and emotional homeostasis, in part, by targeting noradrenergic circuits. In

Cannabinoid system plays a pivotal role in the seizure threshold modulation which is mainly mediated through activation of the cannabinoid CB₁ receptor. There is also several evidence of interaction between cannabinoid system and α₂-adrenoceptors in different paradigms. Using model of clonic seizure

BACKGROUND Cannabinoid agonists induce norepinephrine release in central, spinal, and peripheral sites. Previous studies suggest an interaction between the cannabinoid and adrenergic systems on antinociception. In this study, we sought to verify whether the CB1 and CB2 cannabinoid receptor agonists

Direct-acting cannabinoid receptor ligands are well known to reduce hyperalgesic responses after nerve injury, although their psychoactive side effects have damped enthusiasm for their therapeutic development. Hemopressin (Hp) is a nonapeptide that selectively binds CB1 cannabinoid receptors (CB1

Adenylate cyclase in plasma membranes was inhibited by micromolar concentrations of delta 8-tetrahydrocannabinol and delta 9-tetrahydrocannabinol and by levonantradol and desacetyllevonantradol. This inhibition was noncompetitive for stimulation of the enzyme at the prostanoid receptor by

1. CP 50,556, CP 55,940, nabilone, CP 56,667, delta 9 -tetrahydrocannabinol (THC) and cannabinol each inhibited electrically-evoked contractions of the myenteric plexus-longitudinal muscle preparation of guinea-pig small intestine in a concentration-related manner. The IC50 values of these

OBJECTIVE Cannabidiol is a Cannabis-derived non-psychotropic compound that exerts a plethora of pharmacological actions, including anti-inflammatory, neuroprotective and antitumour effects, with potential therapeutic interest. However, the actions of cannabidiol in the digestive tract are largely
