Antimicrobial Effect of Diphenyl Ditelluride (PhTe) in a Model of Infection by in .

Diphenyl ditelluride (PhTe), an organotelluric compound with pharmacological and toxicological attributes, has shown promise in microorganism studies. , an alternative animal model, is gaining popularity for novel antimicrobial research due to its cost-effectiveness, versatility, and similarity to vertebrate models. Given the rising antibiotic resistance, particularly in (), the exploration of novel antimicrobials is of utmost importance.

Acute 2-phenyl-3-(phenylselanyl)benzofuran treatment reverses the neurobehavioral alterations induced by sleep deprivation in mice.

Sleep is a fundamental state for maintaining the organism homeostasis. Disruptions in sleep patterns predispose to the appearance of memory impairments and mental disorders, including depression. Recent pre-clinical studies have highlighted the antidepressant-like properties of the synthetic compound 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1).

Anxiolytic-like action of 3-((4-methoxyphenyl)selanyl)-2-phenylbenzofuran (SeBZF3) in mice: A possible contribution of the serotonergic system.

Anxiety disorders, characterized by high prevalence rates, cause psychiatric disabilities and are related to impairments in serotoninergic system function. Frequent anxiety recurrence, resistance, and drug adverse effects have driven searches for new therapies. We initially evaluated the anxiolytic-like activity of 3-selanyl-benzo[b]furan compounds (SeBZF1-5) (50 mg/kg, i.

Depressive-like behavior and cognitive impairment induced by acute administration of dexamethasone: Pharmacological effects of 2-phenyl-3-(phenylselanyl)benzofuran in female Swiss mice.

Synthetic glucocorticoid administration has been reported to play a role in depression and cognitive decline. The present study investigated the 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1) effects against the depressive-like behavior, memory impairment, and neurochemical alterations caused by acute dexamethasone administration in female Swiss mice. A dexamethasone dose-response curve (0.

Antidepressant Potential of a Functionalized 3-Selanyl Benzo[]Furan Compound in Mice: Focus on the Serotonergic System.

The present study investigated the antidepressant-like potential of a functionalized 3-selanyl benzo[]furan (SeBZF) in male Swiss mice. To evaluate possible antidepressant-like actions, the compounds SeBZF (50 mg/kg, intragastric, i.g.

2-Phenyl-3-(phenylselanyl)benzofuran elicits acute antidepressant-like action in male Swiss mice mediated by modulation of the dopaminergic system and reveals therapeutic efficacy in both sexes.

Rationale: Depression is a psychiatric disorder that constitutes one of the leading causes of disability worldwide. 2-Phenyl-3-(phenylselanyl)benzofuran (SeBZF1) has been studied as a potential antidepressant drug, but its pharmacological action needs more investigation.

Objectives And Methods: Our aim was to extend information about the antidepressant-like action of SeBZF1 using the mouse tail suspension test (TST).

Selenylated-oxadiazoles as promising DNA intercalators: Synthesis, electronic structure, DNA interaction and cleavage.

A series of selenylated-oxadiazoles were prepared and their interaction with DNA was investigated. The photophysical studies showed that all the selenylated compounds presented absorption between 270 and 329 nm, assigned to combined n→π* and π→π* transitions, and an intense blue emission (325-380 nm) with quantum yield in the range of  = 0.1-0.

Insights into serotonergic and antioxidant mechanisms involved in antidepressant-like action of 2-phenyl-3-(phenylselanyl)benzofuran in mice.

Monoaminergic and oxidative dysfunctions have been reported to play a role in depression. The present study investigated the antioxidant potential as well as the antidepressant-like action of 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1) in male Swiss mice. Time and dose-response curves were analyzed with the forced swim (FST) and tail suspension (TST) tests, in which SeBZF1 elicited antidepressant-like effects.

Synthesis of 3-selanylbenzo[]furans promoted by SelectFluor®.

A simple and practical protocol for the synthesis of 3-selanyl-benzo[]furans mediated by the SelectFluor® reagent was developed. This novel methodology provided a greener alternative to generate 3-substituted-benzo[]furans a metal-free procedure under mild conditions. The intramolecular cyclization reaction was carried out employing an electrophilic selenium species generated through the reaction between SelectFluor® and organic diselenides.

2-Phenylethynyl-butyltellurium attenuates amyloid-β peptide(25-35)-induced learning and memory impairments in mice.

Our previous study demonstrated that 2-phenylethynyl-butyltellurium (PEBT), an organotellurium compound, enhances memory in mice. In this study, the effects of PEBT on cognitive impairment induced by Aβ25-35 were assessed by Morris water maze and step-down inhibitory avoidance tasks. Mice received a single intracerebroventricular injection of Aβ25-35 (3 nmol/3 μl/per site) and a daily oral administration of PEBT (1 mg/kg, for 10 days).

2-phenylethynyl-butyltellurium improves memory in mice.

The present study was conducted to evaluate the effect of 2-phenylethynyl-butyltellurium (PEBT), an organotellurium compound, at doses of 5 and 10 mg/kg on memory, employing the step-down inhibitory avoidance task in mice.
