Bis-(3-amino-2-pyridine) diselenide improves psychiatric disorders -atopic dermatitis comorbidity by regulating inflammatory and oxidative status in mice.

Suppressive effect of bis (3-amino-2-pyridine) diselenide (BAPD) on psychiatric disorders - atopic dermatitis (AD) comorbidity in mice was investigated. To sensitize the animals, 2,4-dinitrochlorobenzene (DNCB) was applied to their dorsal skin on days 1-3. Mice were challenged with DNCB on their ears and dorsal skin on days 14, 17, 20, 23, 26, and 29.

Ultrasound-promoted synthesis of 2-organoselanyl-naphthalenes using Oxone in aqueous medium as an oxidizing agent.

A green methodology to synthesize 2-organoselanyl-naphthalenes based on the reaction of alkynols with diaryl diselenides is described. The electrophilic species of selenium were generated in situ, by the oxidative cleavage of the Se-Se bond of diaryl diselenides by Oxone using water as the solvent. The reactions proceeded efficiently under ultrasonic irradiation as an alternative energy source, using a range of alkynols and diorganyl diselenides as starting materials.

Effectiveness of bis(phenylimidazoselenazolyl) diselenide on a mouse model of inflammatory nociception.

The injection of complete Freund's adjuvant (CFA) in the hindpaw of rodents induces tissue inflammation and nociceptive hypersensitivity. In addition, it has been reported that organoselenium compounds have antinociceptive properties in animal models. The purpose of this study was to investigate the potential antinociceptive effect of bis(phenylimidazoselenazolyl) diselenide (BPIS) in the inflammatory nociception model in mice and its possible mechanism of action.

Bis(phenylimidazoselenazolyl) diselenide as an antioxidant compound: An in vitro and in vivo study.

The organoselenium compounds have been reported for many biological properties, especially as potent antioxidants. The compound bis(phenylimidazoselenazolyl) diselenide (BPIS) is a novel diaryl diselenide derivative, which shows antinociceptive and anti-inflammatory properties in mice, but whose antioxidant activity has not been studied. The present study aimed to investigate the antioxidant and toxicological potential of BPIS in brain of rats in vitro, and the effect of BPIS against the oxidative damage induced by sodium nitroprusside (SNP) in mouse brain.

Hyperthermic seizures enhance responsiveness to pentylenetetrazole and induce cognitive dysfunction: protective effect of 3-alkynyl selenophene.

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 day 21, developed seizures after exposure to a stream of heated air to approximately 41°C.

Involvement of GABAergic and glutamatergic systems in the anticonvulsant activity of 3-alkynyl selenophene in 21 day-old rats.

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.

Evidence for the involvement of μ-opioid and δ-opioid receptors in the antinociceptive effect caused by oral administration of m-trifluoromethyl-diphenyl diselenide in mice.

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 tail-immersion test.
