A new series of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives were synthesized and evaluated for their anticonvulsive activity in a pentylenetetrazole (PTZ)-evoked convulsion model and antidepressant activity in the forced swimming test (FST) model. Eleven synthesized compounds were found to be protective against PTZ-induced seizure and showed the anticonvulsant activity. In addition,...

This study evaluated the antidepressant-like effect of lipid extract of C. striatus in chronic unpredictable mild stress (CUMS) model of depression in male rats and its mechanism of action. The animals were subjected to CUMS for six weeks by using variety of stressors. At the end of CUMS protocol, animals were subjected to forced swimming test (FST) and open field test followed by biochemical a...

OBJECTIVE Brain-derived neurotrophic factor (BDNF) and its specific receptor, tropomyosin-related kinase (TrkB), play important roles in treating depression. In this experiment, we examined whether 7,8-dihydroxyflavone, a novel potent TrkB agonist, could reverse the behavioral and biochemical abnormalities induced by the chronic mild stress (CMS) paradigm in rats. METHODS SD rats were exposed...

A series of phenylselanyl-1H-1,2,3-triazole-4-carbonitriles with different substituents were screened for their binding affinity with serotonin transporter (SERT) and dopamine transporter (DAT) by docking molecular. 5-(4methoxyphenyl)-1-(2-(phenylselanyl)phenyl)-1H-1,2,3-triazole-4-carbonitrile (SeTACN) exhibited the best conformation with SERT even higher than fluoxetine and serotonin, suggest...

Reduced activity of CNS serotonin is reported in unipolar depression and serotonin is the major target of recent antidepressant drugs. However, an acute depletion of serotonin in healthy individuals does not induce depressive symptoms suggesting that depression does not correlate with the serotonin system only. Neuronal plasticity (structural adaptation of neurons to functional requirements) in...

Bio-metal chromium(III) is a crucial microelement for the proper functioning of living organisms. Previous preclinical and clinical studies reported its potential antidepressant properties. The aim of the present study was to examine the effect of antidepressants and noradrenergic and dopaminergic receptor antagonists on chromium chloride (CrCl₃) activity in the forced swim test (FST) in mice a...

OBJECTIVES Hypericum spp. (H.) has been used in traditional medicine for their sedative effect for many years. In spite of many works on this genus, little is known about H. scabrum. In this work antidepressant and its protective effect against hypoxia-induced lethality were evaluated. MATERIALS AND METHODS Antidepressant and its protective effects against hypoxia-induced lethality were evalu...

The new synthesized N-substituted-benzamides are structurally related to tiapride, sulpiride or amisulpride, drugs mainly used in the treatment of psychosis and depressive states. This dual activity is based on the dose-dependent antagonist properties towards dopamine receptors. At low antidepressant doses, benzamides preferentially block presynaptic dopamine D3 autoreceptors, that control dopa...

Buchholzia coriacea, taken by elderly, has phytochemicals that have neuro-active metabolites, and the folkloredocumented its use in neuro-behavioral despairs. Previous study in our laboratory shows that methanol extracts of Buchholziacoriacea (MEBC) seeds possess antidepressant-like potentials in laboratory rodents. This present study was conducted toinvestigate the probable mechanism(s) of act...

Abelmoschus esculentus L. (ladies finger, okra) is a well-known tropical vegetable, widely planted from Africa to Asia and from South Europe to America. In the present study, we investigated the in vitro antioxidant capacity and in vivo protective effect of the aqueous and methanolic seed extracts of Abelmoschus esculentus against scopolamine-induced cognitive impairment using passive avoidance...
