Abstract Background: The inflammation and oxidative stress (OS) have been considered crucial components of the pathogenesis of depression. Edaravone (EDA), a free radical scavenger, processes strong biological activities including antioxidant, anti-inflammatory and neuroprotective properties. However, its role and potential molecular mechanisms in depression remain unclear. The present study aimed to investigate the antidepressant activity of EDA and its underlying mechanisms.Methods: A chronic social defeat stress (CSDS) depression model was performed to explore whether EDA could produce antidepressant effects. C57BL/6J mice were intraperitoneally injected with EDA or Vehicle daily for 10 days. Behaviors tests were then carried out to examine depressive, anxiety-like and cognitive behaviors including social interaction (SI) test, sucrose preference test (SPT), open field test (OFT), elevated plus maze (EPM), novel object recognition (NOR), tail suspension test (TST) and forced swim test (FST). Hippocampal and medial prefrontal cortex (mPFC) tissues were collected for Nissl staining, immunofluorescence, targeted energy metabolomics analysis, measurement of MDA, SOD, GSH and transmission electron microscopy (TEM). Western blotting (WB) and quantitative real time polymerase chain reaction (qRT-PCR) detected the Sirt1/Nrf2/HO-1/Gpx4 signaling pathway. Knockdown experiments were performed to determine the effects of Gpx4 on CSDS mice with EDA treatment by an adeno-associated virus (AAV) vector containing miRNAi(GPX4)-EGFP infusion.Results: The administrated of EDA dramatically ameliorated CSDS-induced depressive and anxiety-like behaviors. Additionally, EDA notably attenuated neuronal loss, microglial activation, astrocyte dysfunction, oxidative stress damage and energy metabolism in the hippocampus (Hip) and mPFC of CSDS-induced mice. Further examination indicated that the application of EDA after the CSDS model significantly increased the protein expressions of Sirt1, Nrf2, HO-1 and Gpx4 in the Hip. In addition, Gpx4 knockdown in CSDS mice abolished EDA-generated efficacy on depressive and anxiety-like behaviors.Conclusion: These findings suggest that EDA possesses potent antidepressant and anxiolytic properties through Sirt1/Nrf2/HO-1/Gpx4 axis and Gpx4-mediated ferroptosis may play a key role in this effect.

Pathological Conditions

The excessive production of free radicals and/or reactive oxygen species (ROS) in gastrointestinal (GI) tract leads to oxidative damages in GI tissues with development of varied pathological conditions and clinical symptoms. Many endogenous as well as exogenous factors are involved in such pathogenesis, herein, focus was given to the factors of metal toxicity, non-steroidal anti-inflammatory drugs (NSAIDs), ischemia-reperfusion, consumption of high fat diet and alcohol, and different pathological conditions and diseases. Since ROS is more or less involved in the GI damages caused by these factors, therefore attempts have been made to develop appropriate therapeutic agents that possess antioxidant properties. Being a potent antioxidant and free radical scavenger, melatonin was suggested as a potent therapeutic answer to these GI damages. The discovery of different binding sites and receptors of melatonin in the GI tissues further proves its local actions to protect these tissues from oxidative stress.  In the review, we attempt to try our best to summarize the current developments regarding the GI injuries caused by oxidative stress and the potential beneficial effects of melatonin on these injuries. The important molecular mechanisms associated with these changes were also highlighted in the discussion. We hope that this review will provide valuable information to consider melatonin as a suitable molecule used for GI tract protection.

Depression is a mental disease that causes severe economic and social burdens. The mechanism for the onset of depression remains largely unknown. Recently, more and more attention is being given to the role of neuroinflammation and oxidative stress in depression. Tauroursodeoxycholic acid (TUDCA), a clinically available agent used to treat cholesterol gallstone and protect neurons against neurodegeneration, has been reported to prevent neuroinflammation and oxidative stress. In this study, we investigated the effect of TUDCA on lipopolysaccharide (LPS)-induced depression-like behavior, neuroinflammation, and oxido-nitrosative stress in mice. Results showed that TUDCA pretreatment (once daily for 7 consecutive days) at the dosage of 200 and 400 mg/kg, but not 100 mg/kg, markedly attenuated LPS (0.83 mg/kg)-induced behavioral abnormalities in the tail suspension test, forced swim test, and sucrose preference test. Further analysis showed that the TUDCA pretreatment (200, 400 mg/kg) not only inhibited the production of proinflammatory cytokines induced by LPS stimulation, such as interleukin-6 and tumor necrosis factor-α, but attenuated LPS-triggered oxido-nitrosative stress in the hippocampus and prefrontal cortex. Taken together, our results provide evidence to show that the TUDCA could be a potential antidepressant, and its antidepressive mechanism may be associated with the inhibition of the neuroinflammatory response and oxido-nitrosative stress in the brain.

Depression is a psychiatric disorder, and oxidative stress is a significant mechanism of damage in this mood disorder. It is characterized by an enhancement of oxidative stress markers and low concentrations of endogenous antioxidants, or antioxidants enzymes. This suggests that antioxidants could have an antidepressant effect. S-allyl cysteine (SAC) is a compound with antioxidant action or free radical scavenger capacity. The purpose of the current research was to evaluate the antidepressant-like effect as well as the antioxidant role of SAC on a preclinical test, using the Porsolt forced swim test (FST). SAC (30, 70, 120, or 250 mg/kg, ip) was administered to male BALB/c mice daily for 17 days, followed by the FST at day 18. Oxidative stress markers (reactive oxygen species, superoxide production, lipid peroxidation, and antioxidant enzymes activities) were analyzed in the midbrain, prefrontal cortex, and hippocampus. SAC (120 mg/kg) attenuated the immobility scores (44%) in the FST, and protection was unrelated to changes in locomotor activity. This antidepressant-like effect was related to decreased oxidative stress, as indicated by lipid peroxidation and manganese-superoxide dismutase (Mn-SOD) activity in the hippocampus. SAC exerts an antidepressant-like effect that correlated, in part, with preventing oxidative damage in hippocampus.

In this study, we synthetized a series of 5-aryl-4,5-dihydrotetrazolo[1,5-a]thieno[2,3-e]pyridine derivatives containing tetrazole and other heterocycle substituents, i.e., triazole, methyltriazole, and triazolone. The forced swim test (FST) and tail suspension test (TST) were used to evaluate the antidepressant activity of the target compounds. The compound 5-[4-(trifluoromethyl)phenyl]-4,5-dihydrotetrazolo[1,5-a]thieno[2,3-e]pyridine (4i) showed the highest antidepressant activity, with a reduced immobility time of 55.33% when compared with the control group. Using an open-field test, compound 4i was shown to not affect spontaneous activity of mice. The determination of in vivo 5-hydroxytryptamine (5-HT) concentration showed that compound 4i may have an effect in the mouse brain. The biological activities of all synthetized compounds were verified by molecular docking studies. Compound 4i showed significant interactions with residues of the 5-HT1A receptor homology model.

Background: An imbalance between pro-oxidants and antioxidants determines the level of oxidative stress which is implicated in the etiopathogenesis of various neuropsychiatric disorders including depression. Therefore, treatment with antioxidants could potentially improve the balance between pro-oxidants and antioxidants. Objective: The objective of this study was to evaluate the ability of astaxanthin, a potential antioxidant, to reduce reserpine-induced depression in BALB/c mice (Mus musculus). Methods: On the behavioral level, antidepressant property of astaxanthin (50 mg/kg, orally) on reserpine (2 mg/kg, subcutaneously) induced depressed mice was evaluated by Forced Swim Test (FST) and Tail Suspension Test (TST). In the biochemical level, the ability of astaxanthin to mitigate reserpine-induced oxidative stress was evaluated by the measurement of Malondialdehyde (MDA) and nitric oxide (NO) in brain, liver and plasma samples. On the other hand, the efficiency of astaxanthin to replenish glutathione depletion and antioxidant enzyme activity augmentation in the same samples were also investigated. Results: Astaxanthin was able to lower reserpine induced immobility time significantly (p<0.05) in FST and TST. Mice treated with astaxanthin showed significantly (p<0.05) low level of oxidative stress markers such as Malondialdehyde (MDA), Nitric Oxide (NO). Consistently, the level of reduced Glutathione (GSH), and the activity of Superoxide Dismutase (SOD) and catalase were augmented due to the oral administration of astaxanthin. Conclusion: This study suggests that astaxanthin reduces reserpine-induced oxidative stress and therefore might be effective in treating oxidative stress associated depression.

In this study, a series of coumarin derivatives were designed and synthesized, their structures were characterized using nuclear magnetic resonance (NMR) and high-resolution mass spectrometry (HRMS) testing methods. In the pharmacological experiment, two behavior-monitoring methods, the forced swim test (FST) and the tail suspension test (TST), were used to determine the antidepressant activity of coumarin derivatives. Compounds that showed potential activity were analyzed for their effects on 5-hydroxytryptamine (5-HT) levels in the brains of mice. Molecular docking experiments to simulate the possible interaction of these compounds with the 5-HT1A receptor was also be predicted. The results of the pharmacological experiments showed that most coumarin derivatives exhibited significant antidepressant activity. Among these compounds, 7-(2-(4-(4-fluorobenzyl)piperazin-1-yl)-2-oxoethoxy)-2H-chromen-2-one (6i) showed the highest antidepressant activity. The results of the measurement of 5-HT levels in the brains of mice indicate that the antidepressant activity of coumarin derivatives may be mediated by elevated 5-HT levels. The results of molecular docking demonstrated that compound 6i had a significant interaction with amino acids around the active site of the 5-HT1A receptor in the homology model. The physicochemical and pharmacokinetic properties of the target compounds were also predicted using Discovery Studio (DS) 2020 and Chemdraw 14.0.

Antioxidant Molecule

Melatonin was discovered by Lerner and Coworkers in 1958, and is the main product secreted by the pineal gland. It is a phylogenetically highly conserved molecule and one of the oldest biological signaling mechanisms. It presents several biological functions, among them the most studied is the regulation of the sleep cycle and wakefulness. In addition, melatonin acts as an immunomodulatory, antioxidant molecule and has anticarcinogenic potential. It also participates in the regulation of mood and control of seasonal reproduction. Melatonin is a potent free radical scavenger and several of its metabolites have the ability to remove singlet oxygen, superoxide radicals, hydroperoxides, hydroxyl radicals and radical lipid peroxides. It easily penetrates cell membranes by being soluble in aqueous and organic media, playing a key role in cell biology. Although their activities are interesting for therapy, their low availability, short half-life, and rapid metabolism restrict their use. In this sense, nanotechnology is a tool that has been studied for the elaboration of systems that improve the pharmacokinetic and pharmacodynamic characteristics of melatonin, in order to potentiate its application in biological models. This review summarizes several studies published in recent years that have shown the most numerous biological activities of melatonin and the improvement of their therapeutic potential through nanotechnology.

Background: The aim of the study was to evaluate the antidepressant effect of opioid analgesic tramadol using forced swim test and tail suspension test models.Methods: The antidepressant effect was assessed by recording the immobility time in Forced swim test (FST) and Tail suspension test (TST). The mice were randomly divided into five groups. Mice belonging to group I was given normal saline (0.1ml/kg) which acted as control. Group II received imipramine (15mg/kg) considered as the standard drug tramadol was given in graded dose (10, 20 and 40 mg/kg) to mice of groups III, IV, V respectively. All drugs were administered intraperitoneally for seven successive days; test was done on 7th day.Results: Tramadol and Imipramine showed antidepressant activity when compared to control. There is dose dependent increase in antidepressant activity of tramadol. The antidepressant activity of imipramine was significantly (P<0.05) more than tramadol at dose 10 and 20 mg/kg but antidepressant activity with tramadol 40mg/kg was comparable to imipramine treated mice.Conclusions: The results of this study indicated the presence of antidepressant activity of tramadol at 40mg/kg.

Ionic Imbalance

Traumatic brain injury (TBI) is a major health concern worldwide and is classified based on severity into mild, moderate, and severe. The mechanical injury in TBI leads to a metabolic and ionic imbalance, which eventually leads to excessive production of reactive oxygen species (ROS) and a state of oxidative stress. To date, no drug has been approved by the food and drug administration (FDA) for the treatment of TBI. Nevertheless, it is thought that targeting the pathology mechanisms would alleviate the consequences of TBI. For that purpose, antioxidants have been considered as treatment options in TBI and were shown to have a neuroprotective effect. In this review, we will discuss oxidative stress in TBI, the history of antioxidant utilization in the treatment of TBI, and we will focus on two novel antioxidants, mitoquinone (MitoQ) and edaravone. MitoQ can cross the blood brain barrier and cellular membranes to accumulate in the mitochondria and is thought to activate the Nrf2/ARE pathway leading to an increase in the expression of antioxidant enzymes. Edaravone is a free radical scavenger that leads to the mitigation of damage resulting from oxidative stress with a possible association to the activation of the Nrf2/ARE pathway as well.

Oxidative Species

Oxidative stress is strongly linked to neurodegeneration and oxidative species can modify many amino acids and proteins in the brain. Cysteine amino acid is most susceptible to oxidative post-translational modifications (PTMs). Reversible or irreversible cysteine PTMs can cause dyshomeostasis, which further continued to cellular damage. Many cysteine dependent proteins and many non-proteins using cysteine as their structural components are affected by oxidative stress. Several cysteine dependent enzymes are acting as antioxidants. Cysteine is a major contributor to glutathione (GSH) and superoxide dismutase (SOD) synthesis. Cysteine precursor N-acetylcysteine (NAC) supplementation is proven as a potent free radical scavenger and increase brain antioxidants and subsequently potentiates the natural antioxidant cellular defense mechanism. Thus, in this chapter, the authors explore the linkage of cellular cysteine networks and neurodegenerative disorders.
