Metaphit induces audiogenic seizures in mice. The most severe clonic/tonic seizures occur 18-24 h after metaphit administration. After 48 h the incidence of the seizure episodes begin to diminish. These audiogenic seizures can be prevented by the administration of either PCP or MK-801 24 h after
Variation in the chemical composition of illicit tablets and powders is common among samples within a given drug seizure. Using microchip electrophoresis (ME), multiple tablets can be screened in a cost-effective and timely manner. This method could be used in conjunction with reporting methods that
The effect of metaphit (a phencyclidine analogue with an acylating isothiocyanate) on kindling development and kindled seizures from amygdala was investigated in rats pretreated once with metaphit. Administration of a single dose of metaphit (10 or 20 mg/kg intraperitoneally i.p.) 4 h before the
We previously demonstrated that metaphit (a phencyclidine analogue with an acylating isothiocyanate group) induces occurrence of audiogenic seizures in mice exposed to audio stimulation 24 h after metaphit administration. We have studied various receptor systems associated with excitatory and
Metaphit [an analogue of phencyclidine (PCP) with an acylating isothiocyanate group] induced audiogenic clonic to clonic-tonic seizures in mice exposed to audio stimulation 24 h after metaphit administration. The incidence of seizures was reduced by treatment 30 min before audio stimulation with
(R)-Lacosamide ((R)-2, (R)-N-benzyl 2-acetamido-3-methoxypropionamide) has recently gained regulatory approval for the treatment of partial-onset seizures in adults. Whole animal pharmacological studies have documented that (R)-2 function is unique. A robust strategy is advanced for the discovery of
Diabetes mellitus is a significant global public health issue. The diabetic state not only precipitates chronic disease but also has the potential to change the toxicity of drugs and chemicals. Acrylonitrile (AN) is a potent neurotoxin widely used in industrial products. This study used a
OBJECTIVE
Epilepsy is a common neurological disorder characterized by recurrent seizures often unresponsive to pharmacological treatment. Brain inflammation is considered a crucial etiopathogenetic mechanism of epilepsy that could be targeted to control seizures. Specific inflammatory mediators
In a study of the possible mechanism of action of metaphit and phencyclidine in the brain, the uptake of glutamate at the luminal side of the blood-brain barrier (BBB) was studied by means of an in situ brain perfusion technique in normal guinea pigs and in those pretreated with metaphit. Metaphit,
An autoantibody against canine brain tissue was detected in the cerebrospinal fluid (CSF) and serum of two Pug dogs (Nos. 1 and 2) by indirect immunofluorescence assay (IFA). Dog No. 1, a 2-year-old male, exhibited severe depression, ataxia, and generalized seizures and died 2 months after the onset
Systemic administration of kainic acid (KA) is a widely used procedure utilized to develop a model of temporal lobe epilepsy (TLE). Despite its ability to induce status epilepticus (SE) in vivo, KA applied to in vitro preparations induces only interictal-like activity and/or isolated ictal
Delta-opioid receptor-selective agonists produce antinociception and convulsions in several species, including mice. This article examines two hypotheses in mice: 1) that antinociception and convulsive activity are mediated through the same type of delta-receptor and 2) that greater delta-agonist
We have advanced a novel strategy to search for lacosamide ((R)-1) targets in the brain proteome where protein binding is expected to be modest. Our approach used lacosamide agents containing affinity bait (AB) and chemical reporter (CR) units. The affinity bait moiety is designed to irreversibly
A series of five membered heterocyclics was synthesized by the reaction between isoniazid and various substituted isothiocyanates and was tested for their anticonvulsant activity by determining their ability to provide protection against convulsions induced by electroconvulsometer. Among the
The novel antiepileptic drug, (R)-N-benzyl 2-acetamido-3-methoxypropionamide ((R)-lacosamide, Vimpat(®) ((R)-1)), was recently approved in the US and Europe for adjuvant treatment of partial-onset seizures in adults. (R)-1 preferentially enhances slow inactivation of voltage-gated Na(+) currents, a
