Abstract
Major depressive disorder (MDD) or Depression is one of the serious neuropsychiatric disorders affecting over 280 million people worldwide. It is 4th important cause of disability, poor quality of life, and economic burden. Women are more affected with the depression as compared to men and severe depression can lead to suicide. Most of the antidepressants predominantly work through the modulation on the availability of monoaminergic neurotransmitter (NTs) levels in the synapse. Current antidepressants have limited efficacy and tolerability. Moreover, treatment resistant depression (TRD) is one of the main causes for failure of standard marketed antidepressants. Recently, inflammation has also emerged as a crucial factor in pathological progression of depression. Proinflammatory cytokine levels are increased in depressive patients. Antidepressant treatment may attenuate depression via modulation of pathways of inflammation, transformation in structure of brain, and synaptic plasticity. Hence, targeting inflammation may be emerged as an effective approach for the treatment of depression. The present review article will focus on the preclinical and clinical studies that targets inflammation. In addition, it also concentrates on the therapeutic approaches' that targets depression via influence on the inflammatory signaling pathways. Graphical abstract demonstrate the role of various factors in the progression and neuroinflammation, oxidative stress. It also exhibits the association of neuroinflammation, oxidative stress with depression.

Abstract
Background Depression or Major depressive disorder (MDD) is a prolonged condition of sadness. MDD is the most common mental disorder that affects more than 264 million people worldwide. According to the monoamine hypothesis, serotonin (5-hydroxy tryptamine, 5-HT), dopamine (DA) and norepinephrine (NE) are the major neurotransmitters (NTs) involved in depression. Methods The methodology adopted for writing this review article is essentially based on the secondary literature search through a systematic literature review. This review mainly focussed on the role of 5-HT3 receptor antagonists (5-HT3RA) in depression and comorbid disorders like anxiety. Results Out of three major NTs mentioned above, serotonin has a predominant role in the pathophysiology of depression. The serotonin type-3 receptors (5-HT3R) are well renowned to be expressed in the central nervous system (CNS) in regions which have significance in the vomiting reflex, perception of pain, the reward system, cognition, depression and anxiety control. 5-HT3R are the receptors of serotonergic family that belong to ligand-gated ion channel. 5-HT3RA inhibit the binding of serotonin to postsynaptic 5-HT3R and increases its availability to other receptors like 5-HT1A, 1B and 1D as well as 5-HT2 receptors and produces anti-depressant-like effect. 5-HT3RA also have an important role in mood and stress disorders. Some of the studies have shown the effectiveness of these agents in stress disorder. Conclusion The present article focussed on the role of 5-HT3R and their antagonists in the treatment of depression and anxiety. Further studies are warranted to prove their efficacy with respect to other standard anti-depressants.

Abstract
Background The transcription factor Nuclear factor erythroid-2-related factor 2 (NRF2) and its principal repressive regulator, Kelch-like ECH-associated protein 1 (KEAP1), are perilous in the regulation of inflammation, as well as maintenance of homeostasis. Thus, NRF2 activation is involved in cytoprotection against many inflammatory disorders. N′-Nicotinoylquinoxaline-2-carbohdyrazide (NQC) was structurally designed by the combination of important pharmacophoric features of bioactive compounds reported in the literature. Methods NQC was synthesised and characterised using spectroscopic techniques. The compound was tested for its anti-inflammatory effect using Lipopolysaccharide from Escherichia coli (LPSEc) induced inflammation in mouse macrophages (RAW 264.7 cells). The effect of NQC on inflammatory cytokines was measured using enzyme-linked immune sorbent assay (ELISA). The Nrf2 activity of the compound NQC was determined using ‘Keap1:Nrf2 Inhibitor Screening Assay Kit’. To obtain the insights on NQC’s activity on Nrf2, molecular docking studies were performed using Schrödinger suite. The metabolic stability of NQC was determined using mouse, rat and human microsomes. Results NQC was found to be non-toxic at the dose of 50 µM on RAW 264.7 cells. NQC showed potent anti-inflammatory effect in an in vitro model of LPSEc stimulated murine macrophages (RAW 264.7 cells) with an IC50 value 26.13 ± 1.17 µM. NQC dose-dependently down-regulated the pro-inflammatory cytokines [interleukin (IL)-1β (13.27 ± 2.37 μM), IL-6 (10.13 ± 0.58 μM) and tumor necrosis factor (TNF)-α] (14.41 ± 1.83 μM); and inflammatory mediator, prostaglandin E2 (PGE2) with IC50 values, 15.23 ± 0.91 µM. Molecular docking studies confirmed the favourable binding of NQC at Kelch domain of Keap-1. It disrupts the Nrf2 interaction with kelch domain of keap 1 and its IC50 value was 4.21 ± 0.89 µM. The metabolic stability studies of NQC in human, rat and mouse liver microsomes revealed that it is quite stable with half-life values; 63.30 ± 1.73, 52.23 ± 0.81, 24.55 ± 1.13 min; microsomal intrinsic clearance values; 1.14 ± 0.31, 1.39 ± 0.87 and 2.96 ± 0.34 µL/min/g liver; respectively. It is observed that rat has comparable metabolic profile with human, thus, rat could be used as an in vivo model for prediction of pharmacokinetics and metabolism profiles of NQC in human. Conclusion NQC is a new class of NRF2 activator with potent in vitro anti-inflammatory activity and good metabolic stability.

Abstract
BACKGROUND 5-HT3 receptor antagonists play a key role in the management of psychiatric disorders such as, depression and anxiety. They may act through modulation of serotonergic transmission. In the present study, a novel and potential 5-HT3 receptor antagonist, 6g (4-benzylpiperazin-1-yl)(3-methoxyquinoxalin-2-yl) methanone, which exhibited good log P (3.08) and pA2 (7.5) values was screened for its anxiolytic property in lipopolysaccharide (LPS) induced anxiety models. METHODS LPS, an endotoxin, present in the cell wall of Gram negative bacteria was injected 0.83 mg/kg, i.p. as a single dose to induce anxiety-like symptoms in mice. Compound 6g (1 and 2 mg/kg, p.o.) and standard fluoxetine (FLX) (20 mg/kg, p.o.) were injected to treatment groups for 7 days and evaluated in various behavioral paradigms such as elevated plus maze (EPM), light and dark (L/D) test, and open field test (OFT). Their effects on serotonin levels in mice brain were also examined. RESULTS The results showed that LPS induced anxiety-like symptoms in mice, as indicated by a significantly decreased percentage open arm entries and percentage time spent in open arms in EPM; decreased time spent in light area and number of transition between chambers in L/D test; decreased ambulation and rearing scores in OFT. Compound 6g (1 and 2 mg/kg, p.o., 7 days) and FLX treatment (20 mg/kg, p.o., 7 days) reversed the LPS-induced behavioral changes and significantly affected all the behavioral parameters mentioned above. In addition 6g (1 and 2 mg/kg, p.o., 7 days) and FLX treatment (20 mg/kg, p.o., 7 days) increased the levels of serotonin in mice brain. CONCLUSIONS Compound 6g produced anxiolytic-like effects in various anxiety paradigms in LPS-treated mice as well as restored the decreased serotonin levels in mice brain.

Abstract
BACKGROUND Several preclinical studies have shown that serotonergic 5-HT3 receptor antagonists play an important role in the management of neuropsychiatric disorders, such as depression and anxiety. In the present study the compound "6n" (N-n-propyl-3-ethoxyquinoxaline-2-carboxamide), a novel 5-HT3 receptor antagonist with an optimal log P (2.52) and pA2 (7.6) value was screened for its neuro-pharmacological potential in chronic rodent models of depression and anxiety named traumatic brain injury (TBI). METHODS In this model, a 1 cm midline scalp incision was made, and the muscles were retracted to expose the skull. A stainless steel disc (10 mm in diameter and 3 mm in depth) was placed centrally between the lambda and bregma regions. The injury was induced using the impact acceleration model of TBI. Specifically, a 400 g metal weight was dropped from a height of 1 m guided by a straight pipe, onto the metal disc placed over the rat's skull. RESULTS The behavioral anomalies of the TBI rats were attenuated by the chronic treatment of compound 6n (1 and 2 mg/kg, p.o.; 14 days) as observed by the modified open field test (ambulation, rearing, and fecal pellet), sucrose consumption test (% sucrose consumption), elevated plus maze [% open arm entries [OAE] and % time spent in open arm (TSOA)], and marble burying test (numbers). In addition, 6n also increased the levels of neurotransmitters (norepinephrine and serotonin) and brain derived neurotrophic factor (BDNF) in TBI rats. CONCLUSIONS The result suggests that compound 6n exhibited antidepressant- and anxiolytic-like effects in rodent models of depression and anxiety.

Abstract
RATIONALE Depression associated with obesity remains an interesting area to study the biological mechanisms and novel therapeutic intervention. OBJECTIVES The present study investigates the effect of a novel 5-HT3 receptor antagonist 3-methoxy-N-p-tolylquinoxalin-2-carboxamide (QCM-4) on several pathogenic markers of depression associated with obesity such as plasma insulin resistance, hippocampal cyclic adenosine monophosphate (cAMP), brain-derived neurotrophic factor (BDNF), serotonin (5-HT) concentrations, hippocampal neuronal damage, and p53 protein expression in high-fat-diet (HFD)-fed mice. METHODS Obesity was experimentally induced in mice by feeding with HFD for 14 weeks followed by administration of QCM-4 (1 and 2 mg/kg, p.o.)/standard escitalopram (ESC) (10 mg/kg, p.o.)/vehicle (10 ml/kg, p.o.) for 28 days. Behavioral assays such as sucrose preference test (SPT); forced swim test (FST); elevated plus maze (EPM); biochemical assays including oral glucose tolerance tests (OGTT), insulin, cAMP, BDNF, and 5-HT concentrations; and molecular assays mainly histology and immunohistochemistry (IHC) of p53 protein in the dentate gyrus (DG), CA1, and CA3 regions of hippocampus in HFD fed mice were performed. RESULTS Chronic treatment with QCM-4 in HFD-fed mice reversed the behavioral alterations in SPT, FST, and EPM. QCM-4 showed poor sensitivity for plasma glucose, improved insulin sensitivity, increased hippocampal cAMP, BDNF, and 5-HT concentrations. In the hippocampal DG, CA1, and CA3 regions, QCM-4 treatment improved the neuronal morphology in the histopathology and inhibited p53 protein expression in IHC assay in HFD-fed mice. CONCLUSION QCM-4 attenuated the depressive-like phenotype in HFD-fed mice by improving behavioral, biochemical, and molecular alterations through serotonergic neuromodulation.

Abstract
AIM The aim of the study was to evaluate a novel 5 HT3 receptor antagonist (6g) on chronic stress induced changes in behavioural and brain oxidative stress parameter in mice. A complicated relationship exists among stressful stimuli, body's reaction to stress and the onset of clinical depression. Chronic unpredictable stressors can produce a situation similar to human depression, and such animal models can be used for the preclinical evaluation of antidepressants. MATERIALS AND METHODS In the present study, a novel and potential 5-HT3 receptor antagonist (4-benzylpiperazin-1-yl)(3-methoxyquinoxalin-2-yl) methanone (6g) with good Log P (3.08) value and pA 2(7.5) values, synthesized in our laboratory was investigated to study the effects on chronic unpredictable mild stress (CUMS)-induced behavioural and biochemical alterations in mice. Mice were subjected to different stress paradigms daily for a period of 28 days to induce depressive-like behaviour. RESULTS The results showed that CUMS caused depression-like behaviour in mice, as indicated by the significant (P < 0.05) decrease in sucrose consumption and locomotor activity and increase in immobility the forced swim test. In addition, it was found that lipid peroxidation and nitrite levels were significantly (P < 0.05) increased, whereas glutathione levels, superoxide dismutase and catalase activities decreased in brain tissue of CUMS-treated mice. '6g' (1 and 2 mg/kg, p.o., 21 days) and fluoxetine treatment (20 mg/kg, p.o., 21 days) significantly (P < 0.05) reversed the CUMS-induced behavioural (increased immobility period, reduced sucrose preference and decreased locomotor activity) and biochemical (increased lipid peroxidation; decreased glutathione levels, superoxide dismutase and catalase activities). However fluoxetine treatment (20 mg/kg, p.o., 21 days) significantly decreased the nitrite level in the brain while '6g' (1 and 2 mg/kg, p.o., 21 days) did not show significant (P < 0.05) effect on the nitrite levels in brain. CONCLUSION Compound '6g' exerted antidepressant-like effects in behavioural despair paradigm in chronically stressed mice by restoring antioxidant mechanisms.

Abstract
Several preclinical studies have revealed antidepressant and anxiolytic-like effect of 5-HT3 receptor antagonists. In our earlier study, we have reported the antidepressive-like effect of 3-methoxy-N-p-tolylquinoxalin-2-carboxamide (QCM-4) in obese mice subjected to chronic stress. The present study deals with the biochemical mechanisms associated with depression co-morbid with obesity. Mice were fed with high fat diet (HFD) for 14 weeks, further subjected for treatment with QCM-4 (1 and 2mg/kg p.o.) and standard antidepressant escitalopram (ESC) (10mg/kg p.o.) for 28 days. Behavioral assays for depression such as sucrose preference test (SPT), forced swim test (FST) and for anxiety such as light and dark test (LDT) and hole board test (HBT) were performed in obese mice. Biochemical assessments including plasma leptin and corticosterone concentration followed by brain oxidative stress parameters malonaldehyde (MDA) and reduced glutathione (GSH) were performed. Results confirmed that QCM-4 exhibits antidepressive effect by increasing the sucrose consumption in SPT, reducing immobility time in FST and anxiolytic effect by increasing transitions and time in light chamber in LDT, increasing head dip and crossing score in HBT. Furthermore, QCM-4 attenuated the hypothalamic-pituitary-adrenal (HPA) axis hyperactivity by reducing the plasma corticosterone, reversing altered plasma leptin, restoring the imbalance of brain MDA and GSH concentration. In conclusion, QCM-4 showed antidepressive and anxiolytic effect by reversing the behavioral alterations that were supported by biochemical estimations in obese mice.

Abstract
Objective: To investigate the antidepressant-like effect of N-(benzo[d] thiazol-2-yl)-3- ethoxyquinoxalin-2-carboxamide 6k, a 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist using rodents behavioral battery tests. Materials and Methods: 6k screening was performed with behavioral assays for depression-like forced swim test (FST) at several single doses (0.25-4 mg/kg, intraperitoneal injection (i.p.)) to test the potency of 6k, in which 2 and 4 mg/kg doses were found to be most effective and hence, in further behavioral assays including mechanistic model like 5-hydroxytryptophan (5-HTP)-induced head twitches was performed in mice at acute doses of 6k (2 and 4 mg/kg, i.p.). Furthermore, olfactory bulbectomy (OBX), a surgical model-induced behavioral alterations was performed in rats, and the effect of 6k administered orally (2 and 4 mg/kg, p.o.) after subchronic treatment for 14 days starting from day 15 of postsurgery was examined by percent sucrose preference test and modified open field test (OFT). Results: 6k (1, 2, and 4 mg/kg, i.p.) reduced the immobility time and increased the swimming behavior in FST without affecting the baseline locomotor score showing antidepressant-like effect. 5-HTP-induced head twitch response was potentiated by 6k (2 and 4 mg/kg, i.p.), which indicated rise in the serotonergic neurotransmission in the brain. 6k (2 and 4 mg/kg, p.o.) showed anti-anhedonia effect by increasing the sucrose consumption and reversed the behavioral alterations when exposed to modified open field in OBX rats after subchronic treatment for 14 days, thus exhibiting antidepressant-like effect. Conclusion: 6k attenuated the behavioral derangement in rodents-based behavioral battery tests for depression, indicating antidepressant-like potential.

Abstract
Stimulation of high oxidative stress in the brain is considered as an important factor for neurotoxicity towards the pathophysiology of chronic stress-induced depression disorder. In the present research, a potential 5-HT₃ receptor antagonist N-n-butyl-3-methoxy quinoxaline-2-carboxamide (6o) having good Log P (2.60) and pA₂ (7.7) values was examined for its effect on the behavioral and biochemical changes induced by the chronic unpredictable mild stress (CUMS) model. In the current investigation mice were introduced to different stress procedures daily for a period of 28 days to induce a depressive-like behavior. The results show that CUMS caused a depression-like behavior in mice, as indicated by the significant decrease in sucrose consumption and locomotor activity and increase in immobility in the forced swim test (FST). Moreover, it was found that oxidative stress markers such as lipid peroxide and nitrite levels were significantly increased, whereas, antioxidant enzymes such as glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) levels were decreased in the brain tissue of CUMS-subjected mice. "Compound 6o" (1 and 2 mg/kg, p.o.) and fluoxetine treatment (20 mg/kg, p.o.) for a period of 21 days altered the CUMS-induced behavioral (increased immobility period, reduced sucrose preference and decreased locomotor activity) and biochemical (increased lipid peroxide, increased brain nitrite; decreased GSH, SOD and CAT levels) alterations. Moreover normal mice treated with "compound 6o" (2 mg/kg, p.o.) showed a significant decrease in the duration of immobility in FST as compared to normal vehicle treated mice. In conclusion, "compound 6o" produced antidepressant-like effects in behavioral despair paradigm in chronically stressed mice by restoring antioxidant enzyme activity.

Abstract
Objective: The present study was designed to investigate the antidepressant potential of N-n-butyl-3-ethoxyquinoxalin-2-carboxamide (6p), a novel 5-HT3 receptor antagonist in rodent behavioral models of depression. Materials and Methods: The compound 6p was examined in various behavioral models like forced swim test (FST), tail suspension test (TST), mechanistic models [5-hydroxytryptophan (5-HTP)-induced head twitch and reserpine-induced hypothermia (RIH)], and in chronic surgery model-olfactory bulbectomy in rats. Results: Compound 6p (1, 2, and 4 mg/kg, i.p.) exhibited antidepressant-like effect in FST and TST after acute treatment without having an effect on baseline locomotor activity. Moreover, 6p (2 mg/kg, i.p.), potentiated the 5-HTP–induced head twitch responses in mice and inhibited the RIH in rats. Chronic treatment (14 days) with 6p (1 and 2 mg/kg, p.o.) and paroxetine (10 mg/kg, p.o.) in rats significantly reversed the behavioral anomalies induced by bilateral olfactory bulbectomy using open field exploration. Conclusion: The preliminary studies reveal that compound 6p exhibits antidepressant-like effect in behavioral rodent models of depression.

Abstract
Aim: The present study was designed to investigate the anxiolytic activity of 6g, a novel serotonin type-3 receptor (5-HT3) receptor antagonist in experimental mouse models of anxiety. Materials and Methods: The anxiolytic activity of “6g” (1 and 2 mg/kg, intraperitoneally [i.p.]) was evaluated in mice by using a battery of behavioral tests of anxiety such as elevated plus maze (EPM), light-dark (L&D) box, hole board (HB), and open field test (OFT) with diazepam (2 mg/kg, i.p.) as standard anxiolytic. None of the tested dose of “6g” affects the base line locomotion. Results: The new chemical entity “6g” (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the percentage of time spent and number of entries in open arm in the EPM test. In the L&D test compound “6g” (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the total time spent in light compartment as well as number of transitions from one compartment to other. Compound “6g” (1 and 2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) also significantly (P < 0.05) increased number of head dips, whereas significantly (P < 0.05) decreased the head dipping latency in HB test as compared to vehicle control group. In addition, 6g (2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) significantly (P < 0.05) increased the ambulation scores (square crossed) in OFT and there was no significant effect of 6g (1 and 2 mg/kg, i.p.) and diazepam (2 mg/kg, i.p.) on rearing scores. Conclusion: In conclusion, these findings indicated that compound “6g” exhibited an anxiolytic-like effect in animal models of anxiety.

Abstract
Abstract
Objectives
The inconsistent therapeutic outcome necessitates identifying novel compounds for the treatment of depression. Therefore, the present study is aimed at evaluating the antidepressant-like effects of a novel 5-HT3 receptor antagonist 3-methoxy-N-p-tolylquinoxalin-2-carboxamide (QCM-4) on chronic unpredictable mild stress (CUMS) induced behavioral and biochemical alterations in mice.
Methods
Animals were subjected to different stressors for a period of 28 days. Thereafter, battery tests like locomotor score, sucrose preference test, forced swim test (FST), tail suspension test (TST), elevated plus maze (EPM) and open field test (OFT) were performed. Biochemical assays like lipid peroxidation, nitrite levels, reduced glutathione (GSH), catalase and superoxide dismutase (SOD) were assessed in brain homogenate.
Key findings
QCM-4 dose dependently reversed the CUMS induced behavioral and biochemical alterations by increasing the sucrose consumption, reducing the immobility time in FST and TST, increasing the percent time in open arm in EPM and increasing the ambulation along with the rearings and decreased number of fecal pellets in OFT. Further, biochemical alterations were attenuated by QCM-4 as indicated by reduced lipid peroxidation and nitrite levels and elevated antioxidant enzyme levels like GSH, catalase and SOD.
Conclusions
QCM-4 attenuated the behavioral and biochemical derangements induced by CUMS in mice, indicating antidepressant behavior of the novel compound.

Abstract
Aim: The present study was designed to investigate the antidepressant potential of (4-phenylpiperazin-1-yl) (quinoxalin-3-yl) methanone (4a), a novel 5-HT3 receptor antagonist, with an optimal log P (2.84) and pA2 value (7.3) greater than ondansetron (6.9) using rodent behavioural models of depression. Materials and Methods: Swiss albino mice were used in actophotometer test, forced swim test (FST) and 5-hydroxytryptophan (5-HTP) induced head twitch response. Reserpine induced hypothermia (RIH) and olfactory bulbectomy were performed in male Wistar rats. Statistical analysis was carried out by using one-way analysis of variance followed by Tukey's test. Results: Acute treatment of 4a (1-4 mg/kg, i.p.) in mice produced antidepressant-like effects in FST without affecting the baseline locomotion in actophotometer test. Further, 4a (2-4 mg/kg, i.p.) potentiated the 5-HTP induced head twitches response in mice and also antagonized RIH in rats. Furthermore, sub-chronic (14 days) treatment with 4a (2-4 mg/ kg, p.o.) significantly attenuated the behavioural anomalies induced by bilateral olfactory bulbectomy in rats in modified open field exploration. Conclusions: These preliminary investigations confirm that 4a exhibits antidepressant-like activity in behaviour based rodent models of depression.

Abstract
The present research was designed to explore the anxiolytic-like activity of a novel 5-HT3 receptor antagonist (60) in experimental mouse models of anxiety. The anxiolytic activity of '6o' at (1 and 2 mg/kg, ip) was evaluated in mice by using a battery of behavioural tests of anxiety such as elevated plus maze (EPM), light/dark aversion test, hole board (HB) and open field test (OFT) with diazepam (2 mg/kg, ip) as a standard anxiolytic. None of the tested doses of '6o' affected the base line locomotion. Compound '6o' (2 mg/kg, ip) and diazepam (2 mg/kg, ip) significantly increased the percentage of both time spent and open arm entries in the EPM test. Compound '6o' in (1 mg/kg, ip) dose was only able to affect the percentage time spent in open arm significantly in the EPM test. In the light and dark test, compound '6o' (2 mg/kg, ip) and diazepam (2 mg/kg, ip) significantly increased the total time spent in light compartment as well as number of transitions from one compartment to other and number of square crossed. Compound '6o' (1 and 2 mg/kg, ip) and diazepam (2 mg/kg, ip) also significantly increased number of head dips and number of squares crossed, whereas significantly decreased the head dipping latency in HB test as compared to vehicle control group. In addition, '6o' in both the doses and diazepam (2 mg/kg, ip) significantly increased the ambulation scores (squares crossed) in OFT however, there was no significant effect of '6o' (1 and 2 mg/kg, ip) and diazepam (2 mg/kg, ip) on rearing scores. To conclude compound '6o' exhibited an anxiolytic-like effect in animal models of anxiety.

Abstract
The compound 6o (at 0.5, 1 and 2 mg/kg, ip) with optimum log P and pA2 value, was subjected to forced swim test (FST) and tail suspension test (TST). The compound 6o significantly reduced the duration of immobility in mice without affecting the base line locomotion in actophotometer. Moreover, 6o (2 mg/kg, ip), potentiated the 5-hydroxytryptophan (5-HTP)-induced head twitch responses in mice and at 1 and 2 mg/kg, ip antagonized the reserpine-induced hypothermia (RIH) in rats. In interaction studies with various standard drugs/ligands using FST, 6o (1 and 2 mg/kg, ip) potentiated the anti-depressant effect fluoxetine (5 mg/kg, ip) and reversed the depressant effect of parthenolide (1 mg/kg, ip) by reducing the duration of immobility. Furthermore, 6o (1 and 2 mg/kg, ip) potentiated the effect of bupropion (10 mg/kg, ip) in TST. The behavioural anomalies of the olfactory bulbectomised (OBX) rats were augmented by chronic 6o (1 and 2 mg/kg) treatment as observed from the modified open field test (parameters: ambulation, rearing, fecal pellet). The results suggest that compound 6o exhibited anti-depressant like effect in rodent models of depression.

Abstract
The present study was designed to evaluate the antidepressant potential of 5-HT3 receptor antagonist N-n-propyl-3-ethoxyquinoxaline-2-carboxamide (6n). The compound ‘6n’ with optimum log P and pA2 value identified from a series of compounds synthesized in our laboratory was subjected to forced Swim Test (FST) (1, 2, and 4 mg/kg, i.p) and Tail Suspension Test (TST) (1, 2, and 4 mg/kg, i.p.). The compound ‘6n’ significantly reduced the duration of immobility in mice without affecting the baseline locomotion. Moreover, ‘6n’ (2 mg/kg, i.p.) potentiated the 5-hydroxytryptophan (5-HTP)-induced head twitch responses in mice and ‘6n’ at tested dose (1 and 2 mg/kg, i.p.) reversed the reserpine-induced hypothermia in rats. In interaction studies of ‘6n’ with various standard drugs/ligands using FST, ‘6n’ (1 mg/kg, i.p.) potentiated the antidepressant effect of venlafaxine (4 and 8 mg/kg, i.p.) and fluoxetine (10 and 20 mg/kg, i.p.). Additionally, ‘6n’ (1 and 2 mg/kg, i.p.) influenced the effect of harmane (5 mg/ kg, i.p.) as well as reversed the effect of parthenolide (1 mg/kg, i.p.) by reducing the duration of immobility in FST. Furthermore, ‘6n’ (1 mg/kg, i.p.) potentiated the effect of bupropion (10 and 20 mg/kg, i.p.) in TST. Chronic ‘6n’ (1 and 2 mg/kg, i.p.) treatment attenuated the behavioral abnormalities in olfactory bulbectomized rats. In conclusion, these various findings reiterated the antidepressant-like effects of ‘6n’ in behavioral models of depression.

Abstract
The present study was designed to investigate the putative antidepressant and anxiolytic-like effects of N-n-Butylquinoxalin-2-carboxamide (4n), a novel 5-HT3 receptor antagonist, with an optimal log P (2.01) and pA2 value (7.3) greater than ondansetron (6.9) using rodent behavioural models of depression and anxiety. Acute treatment of 4n (1-4 mg/kg, ip) in mice produced antidepressant-like effect in forced swim test (FST) without affecting the baseline locomotion in actophotometer test in mice. 4n (2-4 mg/kg, ip) treatment also potentiated the 5-hydroxytryptophan (5-HTP) induced head twitch response in mice. Further, 4n (1-4 mg/kg, ip) treatment antagonized reserpine induced hypothermia in rats. Chronic treatment (14 days) with 4n (1-4 mg/kg) and paroxetine (10 mg/kg) significantly attenuated the behavioural anomalies induced by bilateral olfactory bulbectomy in rats in modified open field paradigm. An anxiogenic-like behaviour was induced by light alone as the stimulus using light-dark aversion test. 4n (2-4 mg/kg, ip) treatment significantly increased no. of transitions between dark and lit area and the time spent in the lit area. In conclusion, these preliminary investigations confirm that 4n exhibited antidepressant and anxiolytic-like effects in rodent models of depression and anxiety.

Abstract
Employing a ligand-based approach, 3-methoxyquinoxalin-2-carboxamides were designed as serotonin type-3 (5-HT(3) ) receptor antagonists and synthesized from the starting material o-phenylenediamine in a sequence of reactions. The structures of the synthesized compounds were confirmed by spectral data. These carboxamides were investigated for their 5-HT(3) receptor antagonisms in longitudinal muscle myenteric plexus preparations from guinea-pig ileum against a standard 5-HT(3) agonist, 2-methy-5-HT, and their antagonism activities are expressed as pA(2) values. Compounds 6a (pA(2) : 7.2), 6e (pA(2) : 7.0), 6f (pA(2) : 7.5), 6g (pA(2) : 7.5), 6n (pA(2) : 7.0), and 6o (pA(2) : 7.2) exhibited antagonism greater than that of the standard 5-HT(3) antagonist, ondansetron (pA(2) : 6.9).

Abstract
N-Cyclohexyl-3-methoxyquinoxalin-2-carboxamide (QCM-13), a novel 5-HT3 antagonist identified from a series of compounds with higher pA2 (7.6) and good log P (2.91) value was screened in rodent models of depression such as forced swim test (FST), tail suspension test (TST), interaction studies with standard anti-depressants and confirmatory studies such as reversal of parthenolide induced depression and reserpine induced hypothermia. In FST (2 and 4 mg/kg) and TST (2 and 4 mg/kg), QCM-13 significantly reduced the duration of immobility in mice without affecting the base line locomotion. QCM-13 (2 and 4 mg/kg) was also found to have significant interaction with standard anti-depressants (fluoxetine and bupropion in FST and TST respectively). Further, reversal of parthenolide induced depression in mice and reserpine induced hypothermia in rat models indicate the serotonergic influence of QCM-13 for anti-depressant potential.

Abstract
A series of quinoxalin-2-carboxamides were designed as per the pharmacophoric requirements of 5-HT(3) receptor antagonists and synthesized by condensing the carboxylic group of quinoxalin-2-carboxylic acid with various amines in the presence of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 1-hydroxybenzotriazole. The structures of the synthesized compounds were confirmed by physical and spectroscopic data. The carboxamides were evaluated for their 5-HT(3) receptor antagonisms in longitudinal muscle-myenteric plexus preparation from guinea pig ileum against 5-HT(3) agonist, 2-methy-5-HT. All the synthesized compounds showed 5-HT(3) receptor antagonism, (4-benzylpiperazin-1-yl)(quinoxalin-2-yl)methanone was the most potent compound among this series.
