Several heteroaryl semicarbazones were prepared by the reaction of heteroaryl hydrazine carboxamide with aryl aldehydes or ketones. The structures of the synthesized compounds were confirmed by spectral data and elemental analyses. Compounds were tested for anticonvulsant activity utilizing pentylenetetrazole-induced seizure (PTZ) and maximal electroshock seizure (MES) tests at 30, 100 and 300 ...

The history of 'electroshock therapy' (now known as electroconvulsive therapy (ECT)) in Europe in the Third Reich is still a neglected chapter in medical history. Since Thomas Szasz's 'From the Slaughterhouse to the Madhouse', prejudices have hindered a thorough historical analysis of the introduction and early application of electroshock therapy during the period of National Socialism and the ...

The anticonvulsant activity of several 1,2,4-triazole-3-thione derivatives on mouse maximal electroshock-induced seizures was tested in this study. Characteristic features of all active compounds were rapid onset of action and long lasting effect. Structure-activity observations showed that the probability of obtaining compounds exerting anticonvulsant activity was much higher when at least one...

Series of 3, 4-disubstituted benzaldehyde-N-(6-substituted-1,3-benzothiazol2-yl)semicarbazones (4a-t) were synthesized by condensation of the N(substituted-1,3-benzothiazol-2-yl)hydrazinecarboxamides with aromatic aldehydes and screened for their anticonvulsant activity using the maximal electroshock seizure (MES) method. The selected compounds were checked for the neurotoxicity by rotorod test...

Ralitoline and CI-953 are anticonvulsant compounds active in both maximal electroshock and kindling models of seizures with rodents. CI-953 (IC50 = 5 microM) and ralitoline (IC50 = 2 microM) both blocked sustained repetitive firing of sodium action potentials with effects on firing activity triggered by spontaneous excitatory postsynaptic potentials at higher concentrations. No effects on ionto...

In the present study, we investigated pharmacodynamic interactions among AO-620, a losigamone analog, and two conventional antiepileptic drugs, valproate (VPA) and phenobarbital (PB). Experiments were conducted in the maximal electroshock test in mice. Isobolographic analysis of the obtained data revealed pure additive interactions between AO-620 and PB applied at three dose ratios of 1:1, 1:3 ...

The aim of this study was to evaluate effects of strychnine, as well as bicuculline and picrotoxin on the anticonvulsant action of felbamate against maximal electroshock (MES)-induced seizures in mice. Strychnine (up to 0.5 mg/kg), bicuculline (up to 2 mg/kg) and picrotoxin (3 mg/kg) did not affect the seizure threshold. However, strychnine (0.25-0.5 mg/kg) and picrotoxin (3 mg/kg) impaired the...
