The anticonvulsant effect of cannabinoid compound has been shown in various models of seizure. On the other hand, there are controversial findings about the role of large conductance calcium-activated potassium (BK) channels in the pathogenesis of epilepsy. In this study, the effect of arachidonyl-2′-chloroethylamide (ACEA), a CB1 receptor agonist, and a BK channel antagonist, paxilline, either...

Recent studies on cannabinoid-induced analgesia implicate certain transient receptor potential (TRP) channels as a therapeutic target along with metabotropic cannabinoid receptors. Although TRP ankyrin 1 (TRPA1)-selective cannabinoids, such as (R)-(+)-[2,3-dihydro-5-methyl-3-(4-morpholinylmethyl) pyrrolo-[1,2,3-d,e]-1,4-benzoxazin-6-yl]-1-naphthalenyl-methanone (WIN55,212), are effective at des...

Cannabinoids have been suggested as a therapeutic target for a variety of brain disorders. Despite the presence of their receptors throughout the auditory system, little is known about how cannabinoids affect auditory function. We sought to determine whether administration of arachidonyl-2'-chloroethylamide (ACEA), a highly-selective CB1 agonist, could attenuate a variety of auditory effects ca...

The anticonvulsant effect of cannabinoid compound has been shown in various models of seizure. On the other hand, there are controversial findings about the role of large conductance calcium-activated potassium (BK) channels in the pathogenesis of epilepsy. Also, there is no data regarding the effect of co-administration of cannabinoid type 1 (CB1) receptor agonists and BK channels antagonists ...

N-methyl-D-aspartate (NMDA) receptor antagonists show therapeutic potential as neuroprotectants, analgesics, and anticonvulsants. In this context, we used electrical recording techniques to study the in vitro pharmacology of two novel quinoxalinediones, i.e., ACEA-1021 and ACEA-1031 (5-nitro-6,7- dichloro- and 5-nitro-6,7-dibromo-1,4-dihydro-2,3-quinoxalinedione, respectively). Assays with NMDA...

Pseudomonas aeruginosa is an opportunistic human pathogen and a common cause of chronic infections in individuals with cystic fibrosis (CF). Oxygen limitation was recently reported to regulate the expression of a major virulence determinant in P. aeruginosa, the type III secretion system (T3SS). Here, we show that expression of the T3SS in oxygen-limited growth conditions is strongly dependent ...

BACKGROUND Both propofol and volatile anesthetics have been reported to interact with the endocannabinoid system. The purpose of this study was to evaluate the effect of selective agonists for cannabinoid receptor types 1 and 2 on etomidate-induced sedation. METHODS A controlled, blinded, experimental study was performed in 20 mice that received intraperitoneal injections of etomidate, the ca...

The present study shows that chronic administration of the cannabinoid receptor type 1 (CB1) receptor agonist arachidonyl-2-chloroethylamide (ACEA) at pre-symptomatic or at early symptomatic stages, at a non-amnesic dose, reduces the cognitive impairment observed in double AβPP(swe)/PS1(1dE9) transgenic mice from 6 months of age onwards. ACEA has no effect on amyloid-β (Aβ) production, aggregat...

Escherichia coli changes its metabolism in response to environmental circumstances, and metabolic adaptations are evident in hungry bacteria growing slowly in glucose-limited chemostats. The role of isocitrate lyase (AceA) was examined in E. coli growing under glucose limitation. AceA activity was elevated in a strain-dependent manner in the commonly used E. coli K-12 laboratory strains MG1655 ...

Cannabinoid1 (CB1) receptors are located at CNS sites, including the spinal cord, involved in somatosensory processing. Analgesia is one of the tetrad of behaviors associated with cannabinoid agonists. Here, effects of a potent cannabinoid CB1 receptor agonist arachidonyl-2-chloroethylamide (ACEA) on evoked responses of dorsal horn neurons in anesthetized rats were investigated. Extracellular r...
