It has been repeatedly reported that NMDA receptors may contribute to ethanol-induced discriminative stimulus effects and withdrawal syndrome. However, the role of NMDA receptors in the reinforcing properties of ethanol remains unclear. The aim of the present study was to evaluate effects of the
The present study characterized the in vitro NMDA receptor antagonistic properties of novel amino-alkyl-cyclohexane derivatives and compared these effects with their ability to block excitotoxicity in vitro and MES-induced convulsions in vivo. The 36 amino-alkyl-cyclohexanes tested displaced
Because of its widespread involvement in the physiology and pathology of the CNS, the glutamatergic system has gained considerable attention as a potential target for development of new agents for a number of therapeutic indications. In this respect, the glutamate receptor subtype of the NMDA type
There is general agreement that moderate affinity uncompetitive NMDA receptor antagonists combine good efficacy and tolerability in animal models of disturbances in glutamatergic transmission. There are several theories on which properties are important for this profile including 1, rapid access to
We investigated the role of 5-HT(2A) and 5-HT(2C) receptors in atypical absence seizures (AAS) induced by trans-1,4-bis[2-chloro-benzylaminomethyl] cyclohexane, dihydrocholoride (AY-9944). The total duration and number and mean duration of the spontaneous bursts of slow spike-and-wave discharges
4-(Dimethylamino)- and 4-(methylamino)-3'-arylspiro[cyclohexane-1,1'(3'H)-isobenzofuran] derivatives were prepared as analogues of previously reported 3-arylspiro[isobenzofuran-1(3H),4'-piperidines]. Metalation of benzanilide with n-butyllithium, addition of 4-(dimethylamino)cyclohexanone, and
Altered function of neuronal nicotinic acetylcholine receptors in the brain has recently been associated with an idiopathic form of partial epilepsy, suggesting that functional alterations of these receptors can be involved in the processes leading to epileptic seizures. Thus, nicotinic
The synthesis and anticonvulsant properties of new piperazine or morpholine acetamides derived from 2-(1,3-dioxoisoindolin-2-yl)-, 2-(1,3-dioxo-3a,4,5,6,7,7a-hexahydroisoindol-2-yl-) and (3,5-dioxo-4-azatricyclo[5.2.1.0(2,6)]dec-8-en-4-yl)-acetic acid were described. Initial anticonvulsant screening
The anticonvulsant gabapentin (1-(aminomethyl)cyclohexane acetic acid) has been found to be effective for treatment of partial seizures, but the mechanism of action is unknown. Recent evidence from the rat optic nerve suggests that gabapentin may enhance promoted release of GABA, which is thought to
Several organic solvents have anticonvulsant or convulsant actions depending on the dose and exposure time. To study if there is a structure-activity relationship for organic solvents as anticonvulsant agents we subjected independent groups of mice to a single 30-min exposure session to inhale
The synthesis and anticonvulsant properties of new 1-(2-pyridinyl)- succinimides [I-XXII] differently substituted at the position-3 of imide ring have been described. The profile of pharmacological activity of these compounds was examined by a maximal electroshock (MES) and pentylenetetrazole
We examined the anesthetic and convulsant properties of 16 unfluorinated to completely fluorinated aromatic compounds, having six to nine carbon atoms (e.g., benzene to 1,3,5-tris(trifluoromethyl)benzene), and four cycloalkanes (cyclopentane to cyclooctane). Benzene, fluorobenzene, toluene,
OBJECTIVE
Memory deficits and depression are common in patients with temporal lobe epilepsy (TLE). Previous positron emission tomography (PET) studies have shown reduced mesial temporal 5HT1A-receptor binding in these patients. We examined the relationships among verbal memory performance,
BACKGROUND
Positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG) shows widespread hypometabolism even in temporal lobe epilepsy (TLE) patients with mesial temporal foci. (18)F-trans-4-fluoro-N-2-[4-(2-methoxyphenyl) piperazin-1-yl]ethyl-N-(2-pyridyl)cyclohexane carboxamide
The effect of the experimental antiepileptic drug gabapentin (1-(aminomethyl) cyclohexane acetic acid; GPT) on the feline trigeminal complex was compared with the effect of established antiepileptic drugs and with the effect of GABAA and GABAB agonists and antagonists. Intravenous injection of 10-60
