Abstract
The compound N-(3-(phenylselanyl)prop-2-yn-1-yl)benzamide (SePB), which combines a selenium atom and a benzamide nucleus in an organic structure, has demonstrated a fast antidepressant-like effect in mice. This action is influenced by the serotonergic system and represents a promising development in the search for novel antidepressant drugs to treat major depressive disorder (MDD), which often resists conventional treatments. This study aimed to further explore the mechanism underlying the antidepressant-like effect of SePB by investigating the involvement of the dopaminergic and noradrenergic systems in the tail suspension test (TST) in mice and evaluating its pharmacokinetic profile in silico. Preadministration of the dopaminergic antagonists haloperidol (0.05 mg/kg, intraperitoneally (i.p.)), a nonselective antagonist of dopamine (DA) receptors, SCH23390 (0.01 mg/kg, subcutaneously (s.c.)), a D1 receptor antagonist, and sulpiride (50 mg/kg, i.p.), a D2/3 receptor antagonist, before SePB (10 mg/kg, intragastrically (i.g.)) prevented the anti-immobility effect of SePB in the TST, demonstrating that these receptors are involved in the antidepressant-like effect of SePB. Administration of the noradrenergic antagonists prazosin (1 mg/kg, i.p.), an α1-adrenergic antagonist, yohimbine (1 mg/kg, i.p.), an α2-adrenergic antagonist, and propranolol (2 mg/kg, i.p.), a β-adrenergic antagonist, did not block the antidepressant-like effect of SePB on TST, indicating that noradrenergic receptors are not involved in this effect. Additionally, the coadministration of SePB and bupropion (a noradrenaline/dopamine reuptake inhibitor) at subeffective doses (0.1 and 3 mg/kg, respectively) produced antidepressant-like effects. SePB also demonstrated good oral bioavailability and low toxicity in computational absorption, distribution, metabolism, excretion, and toxicity (ADMET) analyses. These findings suggest that SePB has potential as a new antidepressant drug candidate with a particular focus on the dopaminergic system.

Abstract
RATIONALE Major Depressive Disorder (MDD) significantly impairs the quality of life for those affected. While the exact causes of MDD are not fully understood, the deficit of monoamines, especially serotonin and noradrenaline, is widely accepted. Resistance to long-term treatments and adverse effects are often observed, highlighting the need for new pharmacological therapies. Synthetic organic compounds containing selenium have exhibited pharmacological properties, including potential antidepressant effects. OBJECTIVE To evaluate the antidepressant-like effect of N-(3-((3-(trifluoromethyl)phenyl)selenyl)prop-2-yn-1-yl) benzamide (CF3SePB) in mice and the involvement of the serotonergic and noradrenergic systems. METHODS Male Swiss mice were treated with CF3SePB (1-50 mg/kg, i.g.) and 30 min later the forced swimming test (FST) or tail suspension test (TST) was performed. To investigate the involvement of the serotonergic and noradrenergic systems in the antidepressant-like effect of CF3SePB, mice were pre-treated with p-CPA (a 5-HT depletor, 100 mg/kg, i.p.) or the receptor antagonists WAY100635 (0.1 mg/kg, s.c., a 5-HT1A receptor antagonist), ketanserin (1 mg/kg, i.p., a 5-HT2A/2C receptor antagonist), ondansetron (1 mg/kg, i.p., a 5-HT3 receptor antagonist), GR110838 (0.1 mg/kg, i.p., a 5-HT4 receptor antagonist), prazosin (1 mg/kg, i.p., an α1-adrenergic receptor antagonist), yohimbine (1 mg/kg, i.p., an α2-adrenergic receptor antagonist) and propranolol (2 mg/kg, i.p., a non-selective beta-adrenergic receptor antagonist) at specific times before CF3SePB (50 mg/kg, i.g.), and after 30 min of CF3SePB administration the FST was performed. RESULTS CF3SePB showed an antidepressant-like effect in both FST and TST and this effect was related to the modulation of the serotonergic system, specially the 5-HT1A and 5-HT3 receptors. None of the noradrenergic antagonists prevented the antidepressant-like effect of CF3SePB. The compound exhibited a low potential for inducing acute toxicity in adult female Swiss mice. CONCLUSION This study pointed a new compound with antidepressant-like effect, and it could be considered for the development of new antidepressants.

Abstract
Pain has a negative impact on public health, reducing quality of life. Unfortunately, current treatments are not fully effective and have adverse effects. Therefore, there is a need to develop new analgesic compounds. Due to promising results regarding the antinociceptive effect of N-(3-(phenylselanyl)prop-2-in-1-yl)benzamide (SePB), this study aimed to evaluate the participation of the dopaminergic and noradrenergic systems in this effect in mice, as well as its toxicity. To this, the antagonists sulpiride (D2/D3 receptor antagonist, 5 mg/kg), SCH-23390 (D1 receptor antagonist, 0.05 mg/kg), prazosin (α1 adrenergic receptor antagonist, 0.15 mg/kg), yohimbine (α2-adrenergic receptors, 0.15 mg/kg) and propranolol (non-selective β-adrenergic antagonist, 10 mg/kg) were administered intraperitoneally to mice 15 min before SePB (10 mg/kg, intragastrically), except for propranolol (20 min). After 26 min of SePB administration, the open field test was performed for 4 min to assess locomotor activity, followed by the tail immersion test to measure the nociceptive response. For the toxicity test, animals received a high dose of 300 mg/kg of SePB. SePB showed an increase in the latency for nociceptive response in the tail immersion test, and this effect was prevented by SCH-23390, yohimbine and propranolol, indicating the involvement of D1, α2 and β-adrenergic receptors in the antinociceptive mechanism of the SePB effect. No changes were observed in the open field test, and the toxicity assessment suggested that SePB has low potential to induce toxicity. These findings contribute to understanding SePB's mechanism of action, with a focus on the development of new alternatives for pain treatment.

Abstract
The serotonin type 4 receptor (5-HT4R)shows promise as a target for treating major depressive disorder (MDD). Studies have demonstrated that 5-HT4R agonists have a faster antidepressant-like effect compared to conventional medications. Developing drugs that modulate this receptor could lead to faster and more effective MDD treatments. The compound N-(3-(phenylselanyl)prop-2-yn-1-yl)benzamide (SePB) induces an antidepressant-like effect in mice. The present study explored if the 5-HT4R mediates SePB's antidepressant effect. For this, male Swiss mice were treated with GR113808 (0.1 mg/kg, intraperitoneally - i.p.), a 5-HT4R antagonist, and SePB (10 mg/kg, intragastrically - i.g), and then subjected to the tail-suspension test (TST) and open-field test (OFT). In silico tests were conducted to analyze SePB's binding affinity to the 5-HT4R and identify participating amino acid residues. The administration of GR113808 blocked the antidepressant-like effect of SePB in the TST without changing locomotor activity in the OFT. Moreover, SePB exhibited a high binding affinity between the 5-HT4R (-7.9 kcal/mol) and the amino acid residues Leu298, Asp100, Thr97, Arg96, Glu80, Leu81, Cys184, Val185, and Phe186 seem to be important for this interaction. The involvement of the 5-HT4R in the antidepressant-like effect of SePB suggests potential for novel therapies in MDD.

Abstract
Major depressive disorder (MDD) is a psychiatric disorder that affects a large portion of the population, with dysregulation of the serotonergic system, which is deeply involved in both the pathophysiology of MDD and mechanism of action of many antidepressants. Current pharmacological therapies do not meet the neurobiological needs of all depressed individuals, making the development of new antidepressants necessary. In recent decades, compounds containing triazoles have become promising due to their range of biological activities, including antidepressant activity. In this study, we evaluated the antidepressant-like effect of a hybrid containing triazole and acetophenone, 1-(2-(4-(4-ethylphenyl)-1H-1,2,3-triazol-1-yl)phenyl)ethan-1-one (ETAP) (0.5-5 mg/kg), in the forced swimming test (FST) and tail suspension test (TST) in mice, as well as the involvement of the serotonergic system in this effect. Our findings demonstrated that ETAP exhibited an antidepressant-like effect from the dose of 1 mg/kg and that this effect is modulated by 5-HT2A/2C and 5-HT4 receptors. We also demonstrated that this effect may be related to inhibition of monoamine oxidase A activity in the hippocampus. Additionally, we evaluated the in silico pharmacokinetic profile of ETAP, which predicted its penetration into the central nervous system. ETAP exhibited a low potential for toxicity at a high dose, making this molecule interesting for the development of a new therapeutic strategy for MDD.

Abstract
The present study investigated the antidepressant-like potential of a functionalized 3-selanyl benzo[b]furan (SeBZF) in male Swiss mice. To evaluate possible antidepressant-like actions, the compounds SeBZF1-5 (50 mg/kg, intragastric, i.g., route) were acutely screened in the tail suspension tests (TSTs). The compound 3-((4-methoxyphenyl)selanyl)-2-phenylbenzofuran (SeBZF3) was then selected. Dose-response and time-response curves revealed that SeBFZ3 exerts antidepressant-like effects in the TST (5-50 mg/kg) and forced swimming test (FST; 50 mg/kg). Additional tests demonstrated that pretreatment with receptor antagonists WAY100635 (5-HT1A; 0.1 mg/kg, subcutaneous route), ketanserin (5-HT2A/C; 1 mg/kg, intraperitoneal, i.p.), or ondansetron (5-HT3; 1 mg/kg, i.p.) blocked the SeBZF3 antidepressant-like effects (50 mg/kg) in the TST. In addition, the coadministration of subeffective doses of SeBZF3 (1 mg/kg, i.g.) and fluoxetine (a selective serotonin reuptake inhibitor; 5 mg/kg, i.p.) produced synergistic action. A high dose of SeBZF3 (300 mg/kg) did not produce oral acute toxicity. The present results provide evidence for the antidepressant-like action of SeBZF3 and its relative safety, as well as predict the possible interactions with the serotonergic system, aiding in the development of novel options to alleviate psychiatric disabilities.

Abstract
RATIONALE Depression is a mental disorder that affects approximately 280 million people worldwide. In the search for new treatments for mood disorders, compounds containing selenium and indolizine derivatives show promising results. OBJECTIVES AND METHODS To evaluate the antidepressant-like effect of 1-(phenylselanyl)-2-(p-tolyl)indolizine (MeSeI) (0.5-50 mg/kg, intragastric-i.g.) on the tail suspension test (TST) and the forced swim test (FST) in adult male Swiss mice and to elucidate the role of the serotonergic system in this effect through pharmacological and in silico approaches, as well to evaluate acute oral toxicity at a high dose (300 mg/kg). RESULTS MeSeI administered 30 min before the FST and the TST reduced immobility time at doses from 1 mg/kg and at 50 mg/kg and increased the latency time for the first episode of immobility, demonstrating an antidepressant-like effect. In the open field test (OFT), MeSeI did not change the locomotor activity. The antidepressant-like effect of MeSeI (50 mg/kg, i.g.) was prevented by the pre-treatment with p-chlorophenylalanine (p-CPA), a selective tryptophan hydroxylase inhibitor (100 mg/kg, intraperitoneally-i.p. for 4 days), with ketanserin, a 5-HT2A/2C receptor antagonist (1 mg/kg, i.p.), and with GR113808, a 5-HT4 receptor antagonist (0.1 mg/kg, i.p.), but not with WAY100635, a selective 5-HT1A receptor antagonist (0.1 mg/kg, subcutaneous-s.c.) and ondansetron, a 5-HT3 receptor antagonist (1 mg/kg, i.p.). MeSeI showed a binding affinity with 5-HT2A, 5 -HT2C, and 5-HT4 receptors by molecular docking. MeSeI (300 mg/kg, i.g.) demonstrated low potential to cause acute toxicity in adult female Swiss mice. CONCLUSION In summary, MeSeI exhibits an antidepressant-like effect mediated by the serotonergic system and could be considered for the development of new treatment strategies for depression.

Abstract
The monoaminergic dysfunction plays a central role in major depressive disorder (MDD), a mental disturbance associated with constant feeling of sadness and lack of interest. The available treatments do not present a desirable efficacy and some of them provoke several adverse effects. In this context, organoselenium compounds and molecules containing the indolizine nucleus have demonstrated interesting pharmacological properties, including antidepressant-like effects. In this study, the antidepressant-like effect of 2-phenyl-1-(phenylselanyl)indolizine (SeI), a selenium-containing indolizine derivative, was investigated on the forced swimming test (FST) and on the tail suspension test (TST) in male Swiss mice. The involvement of the serotonergic system in this effect was also accessed. The selenium compound SeI (10-100 mg/kg, intragastrical (i.g.)) was administered 0.5 h before the behavioral tests, and it diminished the immobility on both FST and TST experiments, which is an indication of antidepressant-like effect. No changing in the locomotor motion was observed in the open-field test (OFT). The anti-immobility effect of SeI was not altered by the preadministration of the selective serotonergic receptor antagonists ondansetron (1 mg/kg, intraperitoneally (i.p.), antagonist of 5-HT3 receptor) and WAY100635 (0.1 mg/kg, subcutaneous route (s.c.), antagonist of 5-HT1A receptor). In contrast, the preadministration of ketanserin (1 mg/kg, i.p., antagonist of 5-HT2A/C receptor) blocked this effect, demonstrating that the antidepressant-like effect of SeI involves 5-HT2A/C. In addition, molecular docking studies showed a strong interaction between SeI and the receptors of 5-HT2A and 5-HT2C. The toxicological results demonstrated that SeI has low potential to cause adverse effects in mice. It was found that the antidepressant-like effect of SeI is related to modulation of the serotonergic system, and this selenium compound could be included in new treatment approaches for MDD.

Abstract
Aging is an ultimate reality that everyone has to face. D-galactose (D-gal) has been used extensively to develop aging model. Trace elements such as selenium (Se) have been used as a potential antioxidant for neuro-protection. The present work aims to develop therapeutic agents such as Se for the treatment of aging-induced neurological ailments such as anxiety, depression, and memory impairment. For this purpose, mice were treated with D-gal at a dose of 300 mg/ml/kg and various doses of Se (0.175 and 0.35mg/ml/kg) for 28 days. Behavioral tests were monitored after treatment days. After the behavioral assessment, mice were decapitated and their brains were collected. Hippocampi were removed from the brain for biochemical, neurochemical, and histopathological analysis. The present findings of behavioral analysis showed that D-gal-induced anxiety- and depression-like symptoms were inhibited by both doses of Se. D-gal-induced memory alteration was also prevented by repeated doses of Se (0.175 and 0.35mg/ml/kg). Biochemical analysis showed that D-gal-induced increase of oxidative stress and inflammatory markers and decrease of antioxidant enzymes and total protein contents in the hippocampus were prevented by Se administration. An increase in the activity of acetylcholinesterase was also diminished by Se. The neurochemical assessment showed that D-gal-induced increased serotonin metabolism and decreased acetylcholine levels in the hippocampus were restored by repeated treatment of Se. Histopathological estimations also exhibited; normalization of D-gal induced neurodegenerative changes. It is concluded that D-gal-induced dysfunction in mice hippocampus caused anxiety, depression, memory impairment, oxidative stress, neuro-inflammation, and histological alterations that were mitigated by Se via its antioxidant potential, anti-inflammatory property, and modulating capability of serotonergic and cholinergic functions.

Abstract
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). Initial experiments investigated the mechanisms involved in the acute antidepressant-like action of SeBZF1 in male Swiss mice. For this purpose, males received noradrenergic or dopaminergic receptor antagonists before acute SeBZF1 administration (50 mg/kg, per oral). In parallel, effects of combined treatment with SeBZF1 and bupropion at sub-effective doses (1 and 3 mg/kg, respectively) were tested. The next experiments were designed to determine the acute effects of SeBZF1 in females through a dose-response curve (5-50 mg/kg). Lastly, the efficacy of a 7-day repeated treatment with SeBZF1 (1 and 5 mg/kg) in mice of both sexes and its safety were evaluated. TST and the open-field test (OFT) were employed in all behavioral experiments. RESULTS Pre-administration of dopaminergic antagonists (SCH23390, a selective D1R antagonist; sulpiride, a selective D2/D3R antagonist; and haloperidol, a non-selective antagonist), but not of adrenergic α1, α2, and β-R antagonists, blocked the acute antidepressant-like effects of SeBZF1 in males. Co-administration of sub-effective doses of SeBZF1 and bupropion reduced the depressive phenotype. In addition, acute treatment with SeBZF1 at 50 mg/kg produced a reduction of female immobility. Finally, repeated treatment with SeBZF1 (1 and 5 mg/kg) was effective in causing antidepressant-like effects in both sexes. Locomotor activity, plasma transaminases, and urea levels remained unaltered after SeBZF1 exposure. CONCLUSION Our findings provide evidence of the involvement of the dopaminergic system in the acutely antidepressant-like action of SeBZF1 in male mice and reveal the compound efficacy when acute or repeatedly administered in both sexes.

Abstract
Here, we addressed the pharmacology and toxicology of synthetic organoselenium compounds and some naturally occurring organoselenium amino acids. The use of selenium as a tool in organic synthesis and as a pharmacological agent goes back to the middle of the nineteenth and the beginning of the twentieth centuries. The rediscovery of ebselen and its investigation in clinical trials have motivated the search for new organoselenium molecules with pharmacological properties. Although ebselen and diselenides have some overlapping pharmacological properties, their molecular targets are not identical. However, they have similar anti-inflammatory and antioxidant activities, possibly, via activation of transcription factors, regulating the expression of antioxidant genes. In short, our knowledge about the pharmacological properties of simple organoselenium compounds is still elusive. However, contrary to our early expectations that they could imitate selenoproteins, organoselenium compounds seem to have non-specific modulatory activation of antioxidant pathways and specific inhibitory effects in some thiol-containing proteins. The thiol-oxidizing properties of organoselenium compounds are considered the molecular basis of their chronic toxicity; however, the acute use of organoselenium compounds as inhibitors of specific thiol-containing enzymes can be of therapeutic significance. In summary, the outcomes of the clinical trials of ebselen as a mimetic of lithium or as an inhibitor of SARS-CoV-2 proteases will be important to the field of organoselenium synthesis. The development of computational techniques that could predict rational modifications in the structure of organoselenium compounds to increase their specificity is required to construct a library of thiol-modifying agents with selectivity toward specific target proteins.

Abstract
The purpose of this study was to investigate the antidepressant mechanism of GEN (geniposide) on depression mice induced by LPS. The mice were intragastrically treated with GEN (10 mg/kg/d or 40 mg/kg/d) or ibrutinib for continuous 7 days prior to LPS injection. The anxiety- and depression-like behaviors of mice were assessed via behavioral tests (sucrose preference test (SPT), tail suspension test (TST), forced swimming test (FST), and open-field test (OFT)). Microglial BV2 cells were treated with GEN or/and ibrutinib and stimulated with LPS. The productions of pro-inflammatory cytokines IL-6 and TNF-α in hippocampus, serum, and supernatant were detected by ELISA. The correlative proteins BTK, p-BTK, JAK2, p-JAK2, STAT1, p-STAT1, BDNF, TrkB, and p-TrkB were assessed through western blot. As a result, GEN ameliorated the anxiety- and depression-like behaviors of mice in behavioral tests. GEN treatment also regulated microglia polarization towards anti-inflammatory phenotype M2 and inhibited the production of pro-inflammatory cytokines IL-6 and TNF-α. In addition, with the application of ibrutinib, the selective inhibitor of BTK, it was proclaimed that the administration of GEN restrained the activation of JAK2/STAT1 pathway via attenuating the hyperphosphorylation of BTK both in mice and BV2 cells. Furthermore, it was also found that GEN activated BDNF/TrkB neuroprotective signaling pathway through the reduction of BTK phosphorylation. From the overall results, we suggested that GEN exerted a beneficial effect on LPS-induced depression in mice possibly through the modulation of BTK/JAK2/STAT1 signaling.
