pyridine/癲癇性発作

A series of twelve compounds (Compounds RNH1-RNH12) of acid hydrazones of pyridine-3-carbohydrazide or nicotinic acid hydrazide was synthesized and evaluated for anticonvulsant activity by MES, scPTZ, minimal clonic seizure and corneal kindling seizure test. Neurotoxicity was also determined for

2-Methyl-6-phenylethynyl-pyridine (MPEP), a selective noncompetitive mGluR5 antagonist, influences the action of conventional antiepileptic drugs in amygdala-kindled seizures in rats. MPEP alone (up to 40 mg/kg) did not affect any seizure parameter. Moreover, the common treatment of MPEP with either

The present study demonstrates that dose combinations of atropine sulfate and 2-pyridine aldoxime methylchloride (2-PAM), which do not produce any overt toxic effects on the behavior of mice or guinea pigs in a stable environment, elicit clonic-tonic convulsions and death when the animals are

This study was designed to verify the influence of MPEP (2-methyl-6-phenylethynyl pyridine hydrochloride), an antagonist of metabotropic glutamate receptor subtype 5 (mGluR5), in seizures and status epilepticus (SE) induced by pilocarpine in young rats. In order to investigate the protective effect

Metabotropic glutamate mGlu5 receptors have been implicated in the regulation of seizures and have been suggested as a target against which discovery of novel anticonvulsants may be possible. However, the experimental literature is not consistent in reporting anticonvulsant efficacy of mGlu5

Two guinea pig models were used to study the anticonvulsant potency of diazepam, midazolam, and scopolamine against seizures induced by the nerve agents tabun, sarin, soman, cyclosarin, O-ethyl S-(2-(diisopropylamino)ethyl)methylphosphonothioate (VX), and O-isobutyl S-(2-diethylamino)ethyl)-methyl

The purpose of this paper was to study the relationship between different neurotransmitter systems and seizure susceptibility in Mongolian gerbils with genetically determined epilepsy. In these animals, generalized tonic-clonic seizures were induced by stimulation with a blast of compressed air. A

Novel 4,5,6,7-tetrahydrothieno[3,2-c]pyridines, 1-thienyl-1,2,3,4-tetrahydroisoquinolines and related compounds, in which the benzene rings of (+)-1 (FR115427) were replaced with heteroaromatic rings such as thiophene, furan, benzothiophene and indole, were synthesized and evaluated for

A series of N'-[substituted] pyridine-4-carbohydrazides were designed and synthesized keeping in view the structural requirement of pharmacophore and evaluated for anticonvulsant activity and neurotoxicity. The anticonvulsant activity of the titled compounds was established after intraperitoneal

Several 2-[(2-methylimidazo[1,2-a]pyridine-3-yl)carbonyl]hydrazono- 3-nonsubstituted/substituted-4-phenyl-4-thiazolines (3a-d, 3f-h) and 3-(2-methylimidazo[1,2-a]pyridine-3-yl)-4-nonsubstituted/substitut ed-5- mercapto-4H-1,2,4-triazoles (4a-f, 4i) were synthesized, characterized and evaluated for

A series of 3,5-(substituted)oxycarbonyl-1,4-dihydro-2,6-dimethyl-4-(substituted)pyridines (1a-j) were synthesized by Hantzsch method for pyridine synthesis. Treatment with chloroacetyl chloride produced

8-Hydrazino derivatives of pyrano[3,4-c]pyridines and derivatives of the new heterocyclic system 3-thioxopyrano[3,4-c][1,2,4]triazolo[4,3-a]pyridines on the basis of methanesulfonates of pyrano[3,4-c]pyridinium were synthesized by optimization of a previously used method.

The selective mGlu5 antagonists, MPEP, 2-methyl-6-phenylethynyl-pyridine, and SIB1893, (E)-6-methyl-2-styryl-pyridine, have been evaluated as antiepileptic drugs in DBA/2 mice and lethargic mice. Clonic seizures induced by the selective mGlu5 agonist, (R,S)-2-chloro-5-hydroxyphenylglycine (CHPG), 3

A series of N-(pyridine-2-yl) derivatives of 2-azaspiro[4.4]nonane- (1a-e), 2-azaspiro[4.5]decane- (2a-e) and 6-methyl-2-azaspiro[4.5]decane-1,3-dione (3a-e) were synthesized and tested for their anticonvulsant activity in the maximum electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ)
