Non-selective benzodiazepines, such as diazepam, interact with equivalent affinity and agonist efficacy at GABA(A) receptors containing either an alpha1, alpha2, alpha3 or alpha5 subunit. However, which of these particular subtypes are responsible for the anticonvulsant effects of diazepam remains uncertain. In the present study, we examined the ability of diazepam to reduce pentylenetetrazoLe ...

The anticonvulsant effects of 3,4-Dimethoxy toluene (DMT), the major constituent of the date palm (Phoenix dactylifera L.) spathe, were investigated using pentylenetetrazole (PTZ), picrotoxin (Pic), nicotine (Nic) and maximal electroshock (MES)-induced seizure models. In PTZ (85 mg/kg)-induced seizures, the intraperitoneally injection of DMT at a dose of 100 mg/kg significantly delayed the onse...

A number of new diazonium salt derivatives of 7-chloro-5-phenyl-3-(phenyl-n-substituted)-diazo-1,3-dihydro-benzo[e][1,4]-diazepin-2-one (IVa-l) from 7-chloro-5-phenyl-1,3-dihydro-benzo[e]-[1,4]-diazepin-2-one (III) with diazonium salts (phenyl diazo salt derivatives) were prepared and tested for anticonvulsant activity. The compounds provided significant protection against maximal electroshock ...

A series of 1,4-piperazine derivatives was synthesized and evaluated for anticonvulsant activity in the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole seizure threshold (ScMet) assays and for neurotoxicity (TOX). The compounds were only moderately effective. The anticonvulsant activity was accompanied by neurotoxicity. 1-[(4-Chlor-3-methylphenoxy)-acetyl]-4-(2-methoxyphe...

In the present work, some new 5-[2(3)-dialkylamino alkoxy] Indole 2, 3-diones and 5-Hydroxyindole 3semicarbazone 2-ones were prepared from 5-hydroxy isatin. The structures of the products were characterized by IR, NMR, MASS Spectral studies. All the compounds were examined for anticonvulsant activity by maximal electroshock seizure (MES) and pentylenetetrazole (PTZ) induced convulsion method. T...

Artocarpus heterophyllus Lam. (Jackfruit) is traditionally used as anticonvulsant. The aqueous and methanol extracts of leaves of Artocarpus heterophyllus Lam. was evaluated for anticonvulsant activity by using Maximal electroshock (MES) and Strychnine induced convulsions models on Swiss albino mice. The methanol extracts of leaves of Artocarpus heterophyllus Lam. were found to be more signific...

To evaluate the anticonvulsant activity of the aerial parts of Verbena officinalis used traditionally by local Iranians for the treatment of convulsion. The anticonvulsant activity of the extract was assessed in pentylenetetrazole (PTZ) and maximal electroshock (MES) induced seizures in mice. Diazepam was used as reference drug. In addition, for investigating the mechanism of V officinalis in P...

BACKGROUND Cytisine (CYT), the most commonly used drug for smoking cessation in Poland, was experimentally found to induce convulsions. There is a lack of studies on the influence of CYT on the anticonvulsant activity of antiepileptic drugs (AEDs). METHODS The effects of CYT on the anticonvulsant activity of six AEDs were examined in maximal electroshock (MES)-induced seizures in mice. RESU...

The study was designed to investigate the effect of ketamine on convulsive behaviour using maximal electroshock (MES) test. An attempt was also made to study the possible receptor mechanisms involved. MES seizures were induced in mice via transauricular electrodes (60 mA, 0.2sec). Seizure severity was assessed by the duration of tonic hindlimb extensor phase and mortality due to convulsions. In...

introduction: jugulans regia (jugulandaceae), astragaus hamosus (papilionaceae), crocus pallasii subsp. haussknechtii boiss. (iridaceae) and cassia angustifolia vahl. (caesalpinaceae) have been suggested as antiepileptic remedies in traditional medicine of iran. the possible anticonvulsant effect of the hydroalcoholic extract of the leaves of j. regia, fruits of a. hamosus, corm of c. haussknec...
