introduction: anxiety is among the most common and treatable mental disorders. adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. the elevated plus-maze (epm) has broadly been used to investigate anxiolytic and anxiogenic compounds. the present study investigated the effects of intraperitoneal (ip) injection of cannabinoid cb1 receptor antagonist (am251) i...

Objective: Argemone mexicana is a Papaveracea plant; some reports have shown their antibacterial, anti-cancer, sedative and probably anti-anxiety properties. From their aerial parts, flavonoids and alkaloids have been isolated, which are intrinsically related to some actions on the central nervous system. The aim of this study was to evaluate the anxiolytic-like effects of the plant, using its ...

The present research was designed to explore the anxiolytic-like activity of a novel 5-HT3 receptor antagonist (60) in experimental mouse models of anxiety. The anxiolytic activity of '6o' at (1 and 2 mg/kg, ip) was evaluated in mice by using a battery of behavioural tests of anxiety such as elevated plus maze (EPM), light/dark aversion test, hole board (HB) and open field test (OFT) with diaze...

Corticotropin-releasing factor(1) (CRF(1)) antagonists may be effective in the treatment of anxiety disorders with fewer side effects compared with classic benzodiazepines. The behavioral effects of DMP904 [4-(3-pentylamino)-2,7-dimethyl-8-(2-methyl-4-methoxyphenyl)-pyrazolo-[1,5-a]-pyrimidine] and its effects on the hypothalamic-pituitary-adrenal (HPA) axis were related to its levels in plasma...

BACKGROUND AND PURPOSE Drugs targeting brain kappa-opioid receptors produce profound alterations in mood. In the present study we investigated the possible anxiolytic- and antidepressant-like effects of the kappa-opioid receptor agonist salvinorin A, the main active ingredient of Salvia divinorum, in rats and mice. EXPERIMENTAL APPROACH Experiments were performed on male Sprague-Dawley rats o...

Polymethoxylavones (PMFs) are known to exhibit significant anti-inflammatory and neuroprotective properties. Nicotiana plumbaginifolia, an annual Bangladeshi herb, is rich in polymethoxyflavones that possess significant analgesic and anxiolytic activities. The present study aimed to determine the antinociceptive and neuropharmacological activities of polyoxygenated flavonoids namely- 3,3',5,6,7...
