We screened the major bioactive flavones isolated from Scutellaria baicalensis (baicalin, baicalein and oroxylin A) for their convulsion related activities. In electrogenic response score system and the pentylenetetrazole seizure model, baicalein but not oroxylin A and baicalin exhibited
Synthesis of furochromone, 2-phenylchromone (flavone) and benzofuran derivatives substituted with thiosemicarbazide or thiazolidin-4-one moieties were accomplished. All the newly synthesized compounds were tested for their anticonvulsant activity in both subcutaneous pentylenetetrazole induced
The functional characterization of hispidulin (4',5,7-trihydroxy-6-methoxyflavone), a potent benzodiazepine (BZD) receptor ligand, was initiated to determine its potential as a modulator of central nervous system activity. After chemical synthesis, hispidulin was investigated at recombinant
A large number of structurally different classes of ligands, many of them sharing the main characteristics of the benzodiazepine (BDZ) nucleus, are active in the modulation of anxiety, sedation, convulsion, myorelaxation, hypnotic and amnesic states in mammals. These compounds have high affinity for
Chrysin (5,7-di-OH-flavone) was identified in Passiflora coerulea L., a plant used as a sedative in folkloric medicine. Chrysin was found to be a ligand for the benzodiazepine receptors, both central (Ki = 3 microM, competitive mechanism) and peripheral (Ki = 13 microM, mixed-type mechanism).
The flowers or leaves of Chrysanthemum boreale (Compositae) have been traditionally used as herb tea to reduce anxiety, insomnia, and stress. Sedative and anticonvulsant activities were evaluated in mice using pentobarbital-induced sleeping assay and pentylenetetrazole (PTZ)-induced convulsion
BACKGROUND
GABAA receptors have been implicated in the pathophysiology of depression, epilepsy and pain disorders. The purpose of this study was to investigate two novel synthetic flavones, 3'-methoxy-6-methylflavone (3'-MeO6MF) and 3'-hydroxy-6-methylflavone (3'-OH6MF), for their effect on GABAA
BACKGROUND
Our previous studies on Asterothamnus centrali-asiaticus Novopokr. (ACN) and Arenaria kansuensis Maxim. (AKM) had led to the isolation of some phytochemical constituents and evaluation of anticonvulsant effect based on their extracts. ACN and AKM have been widely used in traditional
Vitexin is an apigenin flavone glycoside found in food and medicinal plants. It has a variety of pharmacological effects, including antioxidant, anti-inflammatory, anticancer, antinociceptive, and neuroprotective effects. This review study summarizes all the protective effects of vitexin as an
Dried flowers of Matricaria chamomilla L. are largely used to provide sedative as well as spasmolytic effects. In the present study, we examined in particular the pharmacological property of a fraction isolated from a methanolic extract of M. chamomilla, which was identified by HPLC-MS-MS analysis
