1. Uliginosin B, a natural phloroglucinol derivative with antidepressant-like activity, increases Na+,K+-ATPase activity in mice cerebral cortex
ABSTRACT Uliginosin B, a phloroglucinol isolated from Hypericum polyanthemum Klotzsch ex Reichardt, Hypericaceae, has antidepressant-like effect in the forced swimming test in rodents and inhibits monoamines neuronal reuptake without binding to their neuronal carriers. Studies showed the involvement of Na+,K+-ATPase brain activity in depressive disorders, as

2. G-protein activation revealed by [35S]-GTPγS binding assay is involved on the antidepressant-like effect of Hyperi cum caprifoliatum and Hypericum polyanthemumcyclohexane extracts
AbstractPrevious studies by us demonstrated the antidepressant-like and antinociceptive effects of lipophilic extracts and dimeric acyl-phloroglucinols from species of the genus Hypericum native to Southern Brazil. Uliginosin B and HC1 (an enriched phloroglucinol fraction from Hypericum caprifoliatum) are able to inhibit monoamine synaptosomal uptake without

3. Antidepressant-like effect of Hoodia gordonii in a forced swimming test in mice: evidence for involvement of the monoaminergic system
Hoodia gordonii is a plant species used traditionally in southern Africa to suppress appetite. Recently, it has been associated with a significant increase in blood pressure and pulse rate in women, suggesting sympathomimetic activity. The present study investigated the possible antidepressant-like effects of acute and repeated (15 days) administration of H

4. Anxiolytic-like effect of the extract from Bowdichia virgilioides in mice
Current therapeutic for the treatment of anxiety is associated with a wild variety of side effects. The traditional use of plant extract to health care can indicate an important source of new pharmaceuticals. Bowdichia virgilioides Kunth, Fabaceae, is a plant commonly employed in the Brazilian folk medicine to treat inflammatory conditions. Nevertheless, des

5. In vitro evaluation of antioxidant, anxiolytic and antidepressant-like effects of the Bellis perennis extract
Acute toxicity, antioxidant activity in vitro and general pharmacological effects of the flower crude ethanolic extract of Bellis perennis L., Asteraceae, a popular medicine used in South America, were investigated in mice. The oral route LD50 value was found 2.31 g/kg. Oral administration at doses 50, 100 and 150 mg/kg of the extract neither caused signific

6. Chemical composition and anxiolytic-like effects of the Bauhinia platypetala
The pantropical genus Bauhinia, Fabaceae, known popularly as cow's foot, is widely used in folk medicine as antidiabetic. Behavioral effects of the ethanolic extract and ethereal, aqueous and ethyl acetate fractions from B. platypetala Benth. ex Hemsl. leaves were studied in male Swiss mice. The ethanolic extract and fractions were administered intraperitone

7. Avaliação do mecanismo de ação antidepressiva e estudo da toxicidade oral aguda e de doses repetidas de hypericum polyanthemum em camundongos / Evaluation of the antidepressant mechanism of action and oral toxicity study of Hypericum polyanthemum in mice
O objetivo deste trabalho foi ampliar o estudo do mecanismo de ação antidepressivo de Hypericum polyanthemum (POL) e de seu composto derivado da classe dos floroglucinóis uliginosina B (ULI). Considerando o potencial desta planta para o desenvolvimento de novos fármacos, realizou-se um estudo pré-clínico de toxicidade aguda e doses repetidas de POL em

8. PERFIL FARMACOLÓGICO DO TIPO ANTIDEPRESSIVO DO COMPOSTO 3-(4-FLUOROFENILSELENIL)-2,5 DIFENILSELENOFENO: ENVOLVIMENTO DO SISTEMA SEROTONINÉRGICO / ANTIDEPRESSANT-LIKE PHARMACOLOGICAL PROFILE OF 3-(4- FLUOROPHENYLSELENYL)-2,5-DIPHENYLSELENOPHENE: INVOLVEMENT OF SEROTONERGIC SYSTEM
Depression is a serious, recurrent and incapacitating psychiatric condition with a heavy social burden. The pharmacological approach to this disorder employs therapy with antidepressant drugs, which have side effects and numerous limitations. In view of the promising pharmacological properties of containing-selenium molecules, this study evaluated the effect

9. Effects of chronic corticosterone and imipramine administration on panic and anxiety-related responses
It is known that chronic high levels of corticosterone (CORT) enhance aversive responses such as avoidance and contextual freezing. In contrast, chronic CORT does not alter defensive behavior induced by the exposure to a predator odor. Since different defense-related responses have been associated with specific anxiety disorders found in clinical settings, t

10. 5-HT1A autoreceptor modulation of locomotor activity induced by nitric oxide in the rat dorsal raphe nucleus
The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhi

11. Anxiolytic-like and sedative effects of Hydrocotyle umbellata L., Araliaceae, extract in mice
The plant Hydrocotyle umbellata L., Araliaceae (water pennywort), is widely used in Brazilian folk medicine to reduce anxiety. This work investigates the anxiolytic-like effects of the ethanol extract from H. umbellata subterraneous parts as well as the extract's other putative central nervous system effects that could justify its common use. Oral dosing of
