[PMID: 38705428 DOI: 10.1016/j.jep.2024.118292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 05/01/2024] [Accepted: 05/02/2024] [Indexed: 05/07/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tabebuia impetiginosa (Bignoniaceae) was traditionally used for memory enhancement and central nervous system (CNS) stimulation. AIM OF THE STUDY This study aims to create a metabolic profile of the ethyl acetate fraction of T. impetiginosa (TEF) and investigate for the first time its neuroprotective potential on cyclophosphamide (CP)-induced chemobrain, validating its traditional use. MATERIALS AND METHODS Metabolite profiling of TEF was performed using Liquid Chromatography coupled with Quadrupole Time of Flight-Mass/Mass Spectrometry (LC-qTOF-MS/MS). For the in vivo study, CP (200 mg/kg, i.p.) was administered to induce cognitive impairment in rats; TEF (30 mg/kg, p.o.) was administered throughout the 14 days of the experiment to assess its role in mitigating CP-induced neuronal deficits. Behavioral tests including locomotor, Y-maze, and passive avoidance tests were conducted. Additionally, biochemical markers such as reduced glutathione (GSH), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), and caspase-3 immunoexpression were assessed in the hippocampus area. RESULTS Forty-four phytoconstituents were tentatively identified in TEF, mainly iridoids and organic acids. TEF showed significant memory enhancement as evidenced by the increase in step-through latency in the passive avoidance test by 1.5 folds and the increase in sequence alternation percentage (SAP) in the Y-maze test by 67.3%, as compared to CP-group. Moreover, it showed pronounced antioxidant and anti-inflammatory potentials evidenced by the significant elevation in reduced glutathione (GSH) levels by 80% and a pronounced decline in MDA and TNF-α levels by 24% and 45%, respectively relative to the CP group. TEF treatment restored normal hippocampal histological features and attenuated apoptotic caspase-3 expression by 70% compared to the CP group. CONCLUSIONS TEF can act as a promising natural scaffold in managing the chemobrain induced by CP in cancer patients.

Kynurenine monooxygenase inhibition and associated reduced quinolinic acid reverses depression-like behaviour by upregulating Nrf2/ARE pathway in mouse model of depression: In-vivo and In-silico studies. Neuropharmacology 2022; 215:109169. [PMID: 35753430 DOI: 10.1016/j.neuropharm.2022.109169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 05/28/2022] [Accepted: 06/18/2022] [Indexed: 10/17/2022]
Abstract
Kynurenine pathway, a neuroimmunological pathway plays a substantial role in depression. Consistently, increased levels of neurotoxic metabolite of kynurenine pathway; quinolinic acid (QA) found in the suicidal patients and remitted major depressive patients. QA, an endogenous modulator of N-methyl-d-aspartate receptor is produced by microglial cells, may serve as a potential candidate for a link between antioxidant defence system and immune changes in depression. Further, nuclear factor (erythroid-derived 2) like 2 (Nrf2), an endogenous antioxidant transcription factor plays a significant role in maintaining antioxidant homeostasis during basal and stress conditions. The present study was designed to explore the effects of KMO-inhibition (Kynurenine monooxygenase) and association of reduced QA on Keap1/Nrf2/ARE pathway activity in olfactory bulbectomized mice (OBX-mice). KMO catalysis the neurotoxic branch of kynurenine pathway directing the synthesis of QA. KMO inhibitionshowed significant reversal of depressive-like behaviour, restored Keap-1 and Nrf2 mRNA expression, and associated antioxidant levels in cortex and hippocampus of OBX-mice. KMO inhibition also increased PI3K/AKT mRNA expression in OBX-mice. KMO inhibition and associated reduced QA significantly decreased inflammatory markers, kynurenine and increased the 5-HT, 5-HIAA and tryptophan levels in OBX-mice. Furthermore, molecular docking studies has shown good binding affinity of QA towards ubiquitin proteasome complex and PI3K protein involved in Keap-1 dependent and independent proteasome degradation of Nrf2 respectively supporting our in-vivo findings. Hence, QA might act as pro-oxidant through downregulating Nrf2/ARE pathway along with modulating other pathways and KMO inhibition could be a potential therapeutic target for depression treatment.

Antidepressant effects of Enterococcus faecalis 2001 through the regulation of prefrontal cortical myelination via the enhancement of CREB/BDNF and NF-κB p65/LIF/STAT3 pathways in olfactory bulbectomized mice. J Psychiatr Res 2022; 148:137-148.

Abstract
A therapeutic strategy through the gut-brain axis has been proven to be effective in treatment for depression. In our previous study, we demonstrated that Enterococcus faecalis 2001 (EF-2001) prevents colitis-induced depressive-like behavior through the gut-brain axis in mice. More recently, we found that demyelination in the prefrontal cortex (PFC) was associated with depressive-like behavior in an animal model of major depressive disorder, olfactory bulbectomized (OBX) mice. The present study investigated the effects of EF-2001 on depressive-like behaviors in OBX mice and the underlying molecular mechanisms from the perspective of myelination in the PFC. OBX mice exhibited depressive-like behaviors in the tail-suspension, splash, and sucrose preference tests, and decreased myelin and paranodal proteins along with mature oligodendrocytes in the PFC. These behavioral and biochemical changes were all prevented by treatment with EF-2001. Further, EF-2001 treatment increased brain-derived neurotrophic factor (BDNF) and leukemia inhibitory factor (LIF) in the PFC. Interestingly, an immunohistochemical analysis revealed enhanced phospho (p) -cAMP-responsive element binding protein (CREB) expression in neurons, p-nuclear factor-kappa B (NFκB) p65 (Ser536) expression in astrocytes, and p-signal transducer and activator of transcription 3 (STAT3) (Ty705) expression in mature oligodendrocytes in the PFC of OBX mice. From these results, we suggest that EF-2001 administration prevents depressive-like behaviors by regulating prefrontal cortical myelination via the enhancement of CREB/BDNF and NFκB p65/LIF/STAT3 pathways. Our findings strongly support the idea that a therapeutic strategy involving the gut microbiota may be a promising alternative treatment for alleviating symptoms of depression.

Abstract
Although Dolichandrone serrulata flower (DSF) aqueous extract has been shown to possess pharmacological properties, its systemic toxicity has still to be evaluated. The present study aimed to investigate the sub-chronic toxicity effect of DSF extract on biochemical parameters and histological structures of liver, kidney, testis, and epididymis plus vas deferens. Adult male rats were administered DSF at 100, 300, and 600 mg/kgBW via oral gavage for 48 consecutive days while control rats received distilled water. At the end of the experiment, blood, liver, kidney, testis, and epididymis plus vas deferens samples were collected to determine any changes to serum biochemical components including ALT, ALP, and creatinine levels and histological structures. The results revealed no significant difference in body weight and food or water consumption between control and the DSF-treated groups. It was found that DSF significantly increases the weight of epididymis plus vas deferens, while the kidney and liver showed a decrease in the high dose group (P value < 0.05). Histological changes in these vital and reproductive tissues including fibrosis were not observed after administration but ALT, ALP, and creatinine levels were significantly altered in the treated groups (P value < 0.05). These altered levels, however, were still within normal ranges. In conclusion, these findings demonstrated that D. serrulata flower extract had no sub-chronic toxicity on vital and reproductive structures but slightly altered some liver and kidney functions.

Abstract
Medicinal plants and their extracts are natural remedies with enormous potential for treating various diseases, including depression and anxiety. In the case of depression, hundreds of plants have traditionally been used in folk medicine for generations. Different plant extracts and natural products have been analyzed as potential antidepressant agents with validated models to test for antidepressant-like effects in animals, although other complementary studies have also been employed. Most of these studies focus on the possible mediators implicated in these potential effects, with dopamine, serotonin, and noradrenaline being the principal neurotransmitters implicated, both through interference with receptors and with their metabolism by monoamino oxidases, as well as through neuro-endocrine and neuroprotective effects. There are approximately 650 reports of antidepressant-like medicinal plants in PubMed; 155 of them have been compiled in this review, with a relevant group yielding positive results. Saffron and turmeric are the most relevant species studied in both preclinical and clinical studies; St. John's wort or kava have also been tested extensively. To the best of our knowledge, no review to date has provided a comprehensive understanding of the biomolecular mechanisms of action of these herbs or of whether their potential effects could have real benefits. The purpose of this narrative review is to provide an update regarding medicinal plants from the year 2000 to the present to examine the therapeutic potential of these antidepressant-like plants in order to contribute to the development of new therapeutic methods to alleviate the tremendous burden that depression causes worldwide.

Endogenous ω-3 fatty acids in Fat-1 mice attenuated depression-like behaviors, spatial memory impairment and relevant changes induced by olfactory bulbectomy. Prostaglandins Leukot Essent Fatty Acids 2021; 171:102313. [PMID: 34246927 DOI: 10.1016/j.plefa.2021.102313] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 06/12/2021] [Accepted: 06/17/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Olfactory bulbectomy (OB) induced behaviors, hypercortisolism, inflammation and neurotrophin dysfunctions are similar to those observed in depressed patients. Omega (n)-3 polyunsaturated fatty acids (PUFAs) can effectively treat depression via anti-inflammatory and neuroprotective effects. However, n-3 PUFA purities, caloric contents, and ratios in different diets often cause contradictive results. This study used Fat-1 mice, which can convert n-6 to n-3 PUFAs in the brain, to study the effect of n-3 PUFAs on OB-induced behaviors and related changes. METHODS Fat-1 and wild-type littermates were fed safflower oil for 3 months. Behaviors were tested on day 21 after surgery. Monoamine neurotransmitters were measured by HPLC. Macrophage activity was measured by MTT assay. Astrocyte phenotypes A1 S100β, A2 BDNF and cholesterol level were measured by ELISA and total cholesterol assay kits respectively. PUFA profile and membrane fluidity were detected by GC and DPH fluorescence probe respectively. RESULTS OB significantly induced animal hyperactivity and spatial memory impairment, while decreased sucrose consumption and social contact with decreased 5-HT turnover, increased the macrophage activity and S100β/BDNF ratio. Meanwhile, n-3/n-6 PUFAs ratio and total cholesterol level were reduced in OB mice. Whereas, OB-induced behavioral changes were attenuated, which were associated with increasing 5-HT turnover, decrease macrophage activity, restored S100β/BDNF and n-3/n-6 PUFAs ratios, and total cholesterol concentrations in Fat-1 mice. CONCLUSION The present study for the first time demonstrated that endogenous n-3 PUFAs attenuated OB-induced depression-like behaviors and spatial memory impairment through modulating serotonergic and immune function, balancing the astrocyte A1/A2 phenotypes, and normalizing PUFAs profile and membrane function.

Abstract
In this study, the antidepression effects of genistein were investigated in rats induced with chronic mild stress. Animals were designated into the following groups: normal control, control, 10 mg, and 100 mg. The dose was given for 45 consecutive days via the oral route. Sucrose preference analysis, forced swim, and open field tests were performed, and serum cortisol and monoamine levels in brain tissue were determined. The mRNA and protein expression of brain-derived neurotrophic factor (BDNF) was also examined. Supplementation with genistein significantly increased the sucrose preference ratio, locomotor activity, and monoamines and decreased serum cortisol levels. The mRNA expression of BDNF in the brain tissue was substantially reduced by 0.73% in control rats. However, supplementation with genistein significantly increased BDNF mRNA expression (by 107% and 229.6% in groups 10 mg and 100 mg, respectively). Similarly, the protein expression of BDNF increased by 82.3% and 141.2% in groups 10 mg and 100 mg, respectively. Taken together, these results suggest that supplementation with genistein may be effective against depression.

Abstract
Although the fruit extract of Dolichandrone genus was shown to inhibit spermatogenesis, the reproductive toxicity of Dolichandrone serrulata flowers (DSFs) is not documented. Recent study aimed to evaluate the sub-chronic toxicity of DSF on male reproductive system. Antioxidant capacity and total phenolic contents of DSF extract were determined using Folin-Ciocalteu's, 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays. The terpenoid components were determined using nuclear magnetic resonance spectrum. Adult male rats were treated orally with DSF (100, 300 or 600 mg/kg) for 48 days. Histopathology of testis and epididymis was observed. Sperm concentration, viability, acrosome status and morphology were also examined. Expressions of heat shock protein 70 (Hsp70), tyrosine-phosphorylated (TyrPho) proteins, androgen receptor (AR) and steroidogenic acute regulatory (StAR) protein in testis were investigated. Results showed that DSF contained phenolic compounds and terpenoids (phytoandrogens; rengyolone and cleroindicin B). No reproductive histopathology was observed in DSF-treated rats. Although DSF decreased the serum testosterone level, the sperm qualities were not affected. Particularly, sperm concentration of DSF-treated animals was significantly increased. DSF changed the testicular TyrPho proteins but the expression of AR, StAR or Hsp70 was not altered. In conclusion, DSF possesses antioxidant capacity with no toxicity on male reproductive system.

Abstract
Medicinal plants are a rich source of natural products used to treat many diseases; therefore, they are the basis for a new drug discovery. Plants are capable of generating different bioactive secondary metabolites, but a large amount of botanical material is often necessary to obtain small amounts of the target substance. Nowadays, many medicinal plants are becoming rather scarce. For this reason, it is important to point out the interactions between endophytic microorganisms and the host plant, because endophytes are able to produce highly diverse compounds, including those from host plants that have important biological activities. Thence, this review aims at presenting the richness in bioactive compounds of the medicinal plants from Tabebuia and Handroanthus genera, as well as important aspects about endophyte-plant interactions, with emphasis on the production of bioactive compounds by endophytic fungi, which has been isolated from various medicinal plants for such a purpose. Furthermore, bio-prospection of natural products synthesized by endophytes isolated from the aforementioned genera used in traditional medicine could be used to treat illnesses.

Abstract
Oxido-inflammatory aberrations play a substantial role in the pathophysiology of depression. Oxido-inflammatory stress increases catabolism of tryptophan into kynurenine which leads to imbalance in kynurenine and serotonin levels in the brain. Naringenin a flavonoid, has been reported to possess antidepressant property by restoring serotonin and noradrenaline levels in the brain. Its effects on oxido-inflammatory aberrations in depression has not been investigated. With this background, the present study was designed to investigate the antidepressant-like potential of naringenin in olfactory bulbectomy (OBX)-induced neuroinflammation, oxidative stress, altered kynurenine pathway, and behavioural deficits in BALB/c mice. OBX-mice showed depression-like behavioural alterations characterized by hyperactivity in open field, increased immobility time in forced swim test and decreased sucrose preference. After 14 days, OBX-mice were treated by gavage with naringenin (25, 50 and 100 mg/kg) and fluoxetine (5 mg/kg) for two weeks. Naringenin significantly ameliorated depression-like behavioural alterations. Naringenin significantly restored corticosterone levels in serum and antioxidant enzymes (Catalase, SOD GSH), nitrite and MDA in cerebral cortex and hippocampus showing its anti-stress and antioxidant property. Naringenin also significantly decreased elevated pro-inflammatory cytokines like IL-1β, IL-6, TNF-α and NF-ҝβ levels. Naringenin also significantly increased neurotrophic growth factor like BDNF. Naringenin reversed altered levels of tryptophan, serotonin, 5-Hydroxyindole acetic acid and kynurenine in hippocampus and cortex. A positive correlation was found between KYN/TRP ratio and proinflammatory parameters while endogenous antioxidants were negatively correlated. In conclusion, naringenin showed potent neuroprotective effect in depression comparable to the fluoxetine by restoring alterations in kynurenine pathway via its antioxidant and anti-inflammatory potential.

Abstract
Stress renders an individual to experience mental pressure and exhaustion which brings about feelings of anxiety, depression, anger and/or other negative emotions. Depression affects a person's state of mind, behaviour, health and is often associated with suicide. The use of anti-depressant drugs as therapeutic agents is associated with symptoms such as, delayed onset of action, side-effects, drug-drug and dietary interactions, sexual dysfunction, cardiac toxicity, etc. Thus, there is need to target these issues and improve current treatment options. Medicinal plants have long been used in discovering novel treatment strategies and compounds with promising roles in treating various disease conditions. There has been an increase, worldwide, in the use of medicinal plants and herbs for developing nutraceuticals for treatment of depression and other psychiatric disorders. Medicinal plants in their natural forms are valuable as they are rich in various phytochemical compounds. These phytochemical compounds have pharmacological roles in treating various diseases conditions; apart from being widely available in nature and commercially beneficial. The phytochemical compounds in plants are constantly being explored through various experimental studies to determine the molecular basis of how medicinal plants work in relation to drugs and diseases and to develop neutraceuticals for improving conditions. This review summarizes 110 medicinal plants and their phytochemical constituents that have been shown to possess anti-depressant activity. This review also highlights the various mechanisms of anti-depressant action of some of these plants and their plant parts like roots, stem, leaves, flowers, fruit or whole plant; phytochemical compounds showing anti-depressant activity such flavanoids, steroids, saponins, sugars, lectins, alkaloids, etc.; and various anti-depressant screening models used such as tail suspension test, forced swim test, chronic unpredictable stress test, sucrose preference test, monoamine oxidase inhibition assay, learned helplessness test, open field test, hole board test, etc. However, mechanistic evaluation of many of these plants still needs to be investigated and explored.

Comparison of the neuropsychological mechanisms of 2,6-diisopropylphenol and N-methyl-D-aspartate receptor antagonist against electroconvulsive therapy-induced learning and memory impairment in depressed rats. Mol Med Rep 2015; 12:3297-3308. [PMID: 25998151 PMCID: PMC4526078 DOI: 10.3892/mmr.2015.3803] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2014] [Accepted: 04/14/2015] [Indexed: 11/06/2022] Open
Abstract
The present study aimed to examine the neurophysiological mechanisms of the 2,6-diisopropylphenol and N-methyl-D-aspartate (NMDA) receptor antagonist against learning and memory impairment, induced by electroconvulsive therapy (ECT). A total of 48 adult depressed rats without olfactory bulbs were randomly divided into six experimental groups: i) saline; ii) 10 mg/kg MK‑801; iii) 10 mg/kg MK‑801 and a course of ECT; iv) 200 mg/kg 2,6‑diisopropylphenol; v) 200 mg/kg 2,6‑diisopropylphenol and a course of ECT; and vi) saline and a course of ECT. The learning and memory abilities of the rats were assessed using a Morris water maze 1 day after a course of ECT. The hippocampus was removed 1 day after assessment using the Morris water maze assessment. The content of glutamate in the hippocampus was detected using high‑performance liquid chromatography. The expression levels of p‑AT8Ser202 and GSK‑3β1H8 in the hippocampus were determined using immunohistochemical staining and western blot analysis. The results demonstrated that the 2,6‑diisopropylphenol NMDA receptor antagonist, MK‑801 and ECT induced learning and memory impairment in the depressed rats. The glutamate content was significantly upregulated by ECT, reduced by 2,6‑diisopropylphenol, and was unaffected by the NMDA receptor antagonist in the hippocampus of the depressed rats. Tau protein hyperphosphorylation in the hippocampus was upregulated by ECT, but was reduced by 2,6‑diisopropylphenol and the MK‑801 NMDA receptor antagonist. It was also demonstrated that 2,6‑diisopropylphenol prevented learning and memory impairment and reduced the hyperphosphorylation of the Tau protein, which was induced by eECT. GSK‑3β was found to be the key protein involved in this signaling pathway. The ECT reduced the learning and memory impairment, caused by hyperphosphorylation of the Tau protein, in the depressed rats by upregulating the glutamate content.

Abstract
Agmatine is an endogenous neuromodulator which, based on animal and human studies, is a putative novel antidepressant drug. In this study, we investigated the ability of sub-chronic (21 days) p.o. agmatine administration to produce an antidepressant-like effect in the tail suspension test and examined the hippocampal cell signaling pathways implicated in such an effect. Agmatine at doses of 0.01 and 0.1 mg/kg (p.o.) produced a significant antidepressant-like effect in the tail suspension test and no effect in the open-field test. Additionally, agmatine (0.001-0.1 mg/kg, p.o.) increased the phosphorylation of protein kinase A substrates (237-258% of control), protein kinase B/Akt (Ser(473)) (116-127% of control), glycogen synthase kinase-3β (Ser(9)) (110-113% of control), extracellular signal-regulated kinases 1/2 (119-137% and 121-138% of control, respectively) and cAMP response elements (Ser(133)) (127-152% of control), and brain-derived-neurotrophic factor (137-175% of control) immunocontent in a dose-dependent manner in the hippocampus. Agmatine (0.001-0.1 mg/kg, p.o.) also reduced the c-jun N-terminal kinase 1/2 phosphorylation (77-71% and 65-51% of control, respectively). Neither protein kinase C nor p38(MAPK) phosphorylation was altered under any experimental conditions. Taken together, the present study extends the available data on the mechanisms that underlie the antidepressant action of agmatine by showing an antidepressant-like effect following sub-chronic administration. In addition, our results are the first to demonstrate the ability of agmatine to elicit the activation of cellular signaling pathways associated with neuroplasticity/cell survival and the inhibition of signaling pathways associated with cell death in the hippocampus.

NMDA receptors and the L-arginine-nitric oxide-cyclic guanosine monophosphate pathway are implicated in the antidepressant-like action of the ethanolic extract from Tabebuia avellanedae in mice. J Med Food 2014; 16:1030-8. [PMID: 24236576 DOI: 10.1089/jmf.2012.0276] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/11/2022] Open
Abstract
Bark infusion of Tabebuia avellanedae Lorentz ex Griseb is consumed in tropical America folk medicine for the treatment of several diseases, including depressive disorders. It was recently demonstrated that the extract from this plant has antidepressant properties. The present study was aimed at investigating the contribution of N-methyl-D-aspartate (NMDA) receptors and the L-arginine-nitric oxide (NO)-cyclic guanosine 3'5'-monophosphate (cGMP) pathway to the antidepressant-like action of the ethanolic extract from T. avellanedae (EET) in the tail suspension test (TST). The anti-immobility effect of the extract (30 mg/kg, orally [p.o.]) was prevented by pretreatment of mice with NMDA (0.1 pmol/site, intracerebroventicular [i.c.v.]), L-arginine (750 mg/kg, intraperitoneally [i.p.]), and sildenafil (5 mg/kg, i.p.). Additionally, the combination of MK-801 (0.01 mg/kg, p.o.), 7-nitroindazole (25 mg/kg, i.p.), and 1H-[1,2,4]oxadiazole[4,3-a]quinoxalin-1-one (ODQ) (30 pmol/site, i.c.v.) with a subeffective dose of EET (1 mg/kg, p.o.) produced a synergistic antidepressant-like effect in the TST, without causing significant alterations in the locomotor activity. Moreover, the administration of an effective dose of EET (30 mg/kg, p.o.) produced a reduction in NOx levels in the cerebral cortex. Conversely, a subeffective dose of EET (1 mg/kg, p.o.) caused no changes in the cortical NOx levels. Results suggest that the antidepressant-like effect of EET in the TST is dependent on a blockade of NMDA receptor activation and inhibition of NO-cGMP synthesis, significantly extending literature data about the antidepressant-like action of this plant and reinforcing the notion that this plant may be useful in the management of depressive disorders.
