Agastache mexicana is a plant that has long been used in large demands in Mexican folk medicine to treat anxiety, insomnia and pain, among others affections. Chromatographic technique was used to identify ursolic acid (UA), 130.7 mg/g and 20.3 mg/g, as an antinociceptive active compound identified in ethyl acetate and methanol extracts of A. mexicana aerial(More)
The activity-guided fractionation of the ethanol extract of leaves of Annona diversifolia Saff., led to the isolation of palmitone (16-hentriacontanone) as the only anticonvulsant active compound. This aliphatic ketone was highly effective to diminish pentylenetetrazole (PTZ)-induced clonic-tonic seizures and toxicity. Also, it produced a prolongation of(More)
Magnolia dealbata Zucc. is considered to have tranquilizer and anticonvulsant properties in Mexican traditional medicine. In the present study we report the effects of a crude extract of Magnolia dealbata (30, 100 and 300 mg/kg) on mouse central nervous system (CNS). Pharmacological effects were tested on ambulatory activity, anti-anxiety response, sodium(More)
The effects of an ethanol extract of the aerial parts of Ruta chalepensis on the central nervous system (CNS) and LD(50) determination were studied in mice. A crude extract was given systemically and its effects were tested on pentylenetetrazole (PTZ)-induced seizures, sodium pentobarbital-induced hypnosis, exploratory activity, anxiety and nociception.(More)
Pharmacological activation at the basal ganglia of the transcription factor Nrf2, guardian of redox homeostasis, holds a strong promise for the slow progression of Parkinson's disease (PD). However, a potent Nrf2 activator in the brain still must be found. In this study, we have investigated the potential use of the antioxidant compound S-allyl cysteine(More)
It has been declared frequently that valerian may potentiate the effect of other central nervous system (CNS) depressant drugs, however there has been a lack of experimental data. We have evaluated the profile of the interactions between the ethanol extract of Valeriana edulis spp procera and six CNS depressant drugs using an exploratory model to test the(More)
Vitamin C helps to prevent brain oxidative stress and participate in the synthesis of progesterone. It also possesses a progesterone-like effect and acts synergistically with progesterone on the brain. Progesterone and its metabolites, but also vitamin C have been associated with anticonvulsant effects. We evaluated the progesterone concentration 30min and(More)
Tilia genus is commonly used around the world for its central nervous system properties; it is prepared as tea and used as tranquilizing, anticonvulsant, and analgesic. In this study, anticonvulsant activity of the Tilia americana var. mexicana inflorescences and leaves was investigated by evaluating organic and aqueous extracts (100, 300, and 600 mg/kg,(More)
The role of nitric oxide (NO) in the antinociceptive effect of indomethacin was assessed in the pain-induced functional impairment model in the rat (PIFIR model), a model of inflammatory and chronic pain similar to that observed in clinical gout. Oral administration of indomethacin (5.6 mg/kg), a nonselective cyclooxygenase inhibitor, significantly(More)
BACKGROUND Acacetin is a bioflavonoid with pharmacological properties such as antinociceptive/anti-inflammatory activities. However, scientific evidence of its spectrum activity and mechanisms of action is unknown. METHODS Acacetin administered via i.p. was assessed using several nociceptive experimental models such as the writhing test, the formalin test(More)
