The organoselenium compound diphenyl diselenide (PhSe)(2) has shown interesting antioxidant and neuroprotective activities. On the other hand, this compound has also presented some toxic effects. m-Trifluoromethyl-diphenyl diselenide (m-CF(3)-C(6)H(4)Se)(2), a structural analog of (PhSe)(2), has proven to be antipsychotic and antioxidant in mice. The(More)
AIMS In this study we investigated the effect of pre-treatment with 3-alkynyl selenophene (3-ASP) against the increase in responsiveness to pentylenetetrazole [PTZ seizure threshold] and cognitive dysfunction induced by experimental febrile seizures (FS). The effects of 3-ASP were compared to those of diazepam (DZP). MAIN METHODS Young rats, at postnatal(More)
In this study, we investigated the role of GABAergic and glutamatergic systems in the anticonvulsant action of 3-alkynyl selenophene (3-ASP) in a pilocarpine (PC) model of seizures. To this purpose, 21 day-old rats were administered with an anticonvulsant dose of 3-ASP (50 mg/kg, per oral, p.o.), and [3H]γ-aminobutyric acid (GABA) and [3H]glutamate uptakes(More)
Pain is one of the most prevalent conditions, which limits productivity and diminishes quality of life. This study examined the antinociceptive effects of m-trifluoromethyl-diphenyl diselenide [(m-CF3-C6H4Se)2] on behavioral models of pain in mice. The involvement of opioid receptors in (m-CF3-C6H4Se)2-induced antinociception was evaluated in the(More)
A growing body of evidence demonstrates that quinoline compounds have attracted much attention in the field of drug development. Accordingly, 4-phenylselenyl-7-chloroquinoline (4-PSQ) is a new quinoline derivative containing selenium, which showed a potential antioxidant, antinociceptive and anti-inflammatory effect. The present study was undertaken to(More)
The present study examined the effect of peroral administration of bis(phenylimidazoselenazolyl) diselenide (BPIS) in thermal and chemical models of pain in mice. The involvement of the opioid system in the BPIS antinociceptive effect was also examined, as well as potential nonspecific disturbances in locomotor activity or signs of acute toxicity. BPIS(More)
