Evaluation of behavioral and pharmacological effects of Hedyosmum brasiliense and isolated sesquiterpene lactones in rodents.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND Hedyosmum brasiliense Miq. (Chloranthaceae) is an essential Brazilian species largely found in the Atlantic Forest. It is popularly known as "cidrão" and in folk medicine, this aromatic species is widely used as a calmative/tranquilizer and to treat sleep disorders. OBJECTIVE To examine

Pharmacological characterization of the neurotrophic sesquiterpene jiadifenolide reveals a non-convulsant signature and potential for progression in neurodegenerative disease studies.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The 'neurotrophic sesquiterpenes' refer to a group of molecules derived from the Illicium genus of flowering plant. They display neurotrophic effects in cultured neuron preparations and have been suggested to be cognitive enhancers and potential therapeutics for neurodegenerative disorders and

The molecular structure of 2alpha-hydroxyneoanisatin and structure-activity relationships among convulsant sesquiterpenes of the seco-prezizaane and picrotoxane types.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The molecular structure of 2alpha-hydroxyneoanisatin, a positional isomer of the potent neurotoxin anisatin, was determined by X-ray crystallographic analysis. This compound and four further seco-prezizaane type sesquiterpene lactones previously isolated from Illicium floridanum, which represent

Anticonvulsant activity of β-caryophyllene against pentylenetetrazol-induced seizures.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Increasing evidence suggests that plant-derived extracts and their isolated components are useful for treatment of seizures and, hence, constitute a valuable source of new antiepileptic drugs with improved efficacy and better adverse effect profile. β-Caryophyllene is a natural bicyclic

Neuroprotective Dihydro-β-agarofuran-Type Sesquiterpenes from the Seeds of Euonymus maackii.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Twenty-one dihydro-β-agarofuran derivatives were purified from the seeds of Euonymus maackii, and eight compounds (1-8) were identified as new natural products. Their structures were deduced by extensive spectroscopic analysis, X-ray diffraction studies, and comparison of

Biological effects of Ocimum gratissimum L. are due to synergic action among multiple compounds present in essential oil.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Species of genus Ocimum (Lamiaceae) are economically important due to their essential oils and utilization as medicine for many disorders, including the central nervous system. A previous study showed seasonal variations in chemical profile and in central nervous system activities of essential oil

Neurite outgrowth enhancement by jiadifenolide: possible targets.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Covering: 1860-2016A mechanistic link may exist between convulsant plant substances typified by picrotoxinin, and 'neurotrophic' sesquiterpenes like jiadifenolide. Picrotoxinin elicits convulsion by anion blockade of the Cys-loop family of neurotransmitter-gated ion channels. These same receptors

Planarians in pharmacology: parthenolide is a specific behavioral antagonist of cocaine in the planarian Girardia tigrina.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Planarians are traditional animal models in developmental and regeneration biology. Recently, these organisms are arising as vertebrate-relevant animal models in neuropharmacology. Using an adaptation of published behavioral protocols, we have described the alleviation of cocaine-induced planarian

Effects of the Hyptis martiusii Benth. leaf essential oil and 1,8-cineole (eucalyptol) on the central nervous system of mice.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The aim of this study was to characterize the central effects of the Hyptis martiusii leaf essential oil (OEHM) and 1,8-cineole (eucalyptol) using behavioral animal models. Gas chromatography coupled to mass spectrometry (GC/MS) was used to characterize the chemical compounds present in the OEHM.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Epilepsy is a chronic neurological disorder affecting more than 50 million people worldwide, of whom 80% live in low- and middle-income countries. Due to the limited availability of antiseizure drugs (ASDs) in these countries, medicinal plants are the first-line treatment for most

A systematic review on the neuroprotective perspectives of beta-caryophyllene.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Beta (β)-caryophyllene (BCAR) is a major sesquiterpene of various plant essential oils reported for several important pharmacological activities, including antioxidant, anti-inflammatory, anticancer, cardioprotective, hepatoprotective, gastroprotective, nephroprotective, antimicrobial, and

Neuroprotection by extract of Petasites japonicus leaves, a traditional vegetable, against oxidative stress in brain of mice challenged with kainic acid.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND Reactive oxygen radicals have been implicated in the pathophysiology of many neurologic disorders and brain dysfunctions. Kainic acid has been used as a model agent for the study of neurotoxicity of various excitatory amino acids, since it induces neuronal damage through excessive

Natural terpenoids as a promising source for modulation of GABAergic system and treatment of neurological diseases.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

γ-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter reducing neural excitability in the mammalian central nervous system (CNS) with three subclasses of receptors. Several conventional drugs and compounds modulate the GABAergic system, demonstrating different pharmacological effects.
