We evaluated the antidepressant-like effect of kaempferitrin (Km) isolated from the plant Justicia spicigera (Asteraceae), which is used in traditional medicine for relieving emotional disorders, such as "la tristeza" (sadness or dysthymia) and "el humor" (mood changes). The actions of Km were evaluated in a forced swimming test (FST) and a suspension tail test (TST) in mice. We explored the in...

Peony is often used in Chinese herbal medicine for the treatment of depression-like disorders. Our previous studies have demonstrated that the total glycosides of peony exert antidepressant-like effects in animal models. Paeoniflorin is the main active glycoside of peony. The aim of this study was to evaluate the antidepressant-like effects of paeoniflorin in mice, as well as its active mechani...

The mammalian neuropeptide, melanin-concentrating hormone, interacts with two G protein-coupled receptors, melanin-concentrating hormone receptor (MCHR) 1 and MCHR2; however, only MCHR1 is expressed in rats and mice. In the present study, we evaluated MCHR1 antagonism in preclinical models believed to be predictive of antiobesity and antidepressant activity. Central activity of the selective MC...

Background: Parturition depression is an important physiological problem, and several attempts have been made to ascertain this phenomenon. Natural monoterpenes like α-pinene numerous beneficial properties, but no studies done on their antidepressant potential in postpartum animals. Objectives: This study aimed determine the effects of prenatal administration antidepressant-like behavior mice f...

The mammalian neuropeptide, melanin-concentrating hormone (MCH) interacts with two G-protein coupled receptors, MCHR1 and MCHR2; however, only MCHR1 is expressed in rats and mice. In the present study, we evaluated MCHR1 antagonism in preclinical models believed to be predictive of anti-obesity and antidepressant activity. Central activity of the selective MCHR1 antagonist, 6-(4-Chloro-phenyl)-...

Curcumin is the active ingredient of commonly used spice Curuma longa Linn. In the present study, the antidepressant like activity of curcumin and its combination with fluoxetine and imipramine was studied in acute model (three doses 24, 5 and 1 h before test) of forced swimming test (FST) in glass jar and tail suspension test (TST) in mice and in chronic model (14 day study) of FST with water ...

This study aimed to explore the possible mechanisms underlying the antidepressant-like effect of YL-0919, a novel antidepressant candidate with dual activity as a 5-HT1A receptor agonist and a selective serotonin reuptake inhibitor. The animal models commonly used to evaluate potential antidepressants, i.e., tail suspension (TST) in mice and forced swimming test (FST) in mice were used to evalu...

Salvia verticillata is one of the salvia species which possesses remarkable antioxidant activity. In the present study, we investigated the possible effects of hydro-alcoholic extract from Salvia verticillata plant (SVE) in various models of anxiety, depression and seizure in mice. Mice were randomly divided into control (saline), SVE-treated and standard treatment groups. The SVE-treated group...
