The anticonvulsant activity of the ethyl esters of the major valproic acid metabolites was assessed against minimal pentylenetetrazol seizures in adult male ICR mice. The ethyl ester 3-hydroxy-propylpentanoic acid was found to possess significant anticonvulsant activity.
Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid (n-3 PUFA) which has been shown to raise seizure thresholds following acute administration in rats. The aims of the present experiment were the following: 1) to test whether subchronic DHA administration raises seizure threshold in
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
The omega-guanidino fatty acids C6-C12 were prepared by amidination of the corresponding omega-amino acids. omega-Amino acids C7-C10 which are not available commercially, were obtained by use of Hofmann degradation of the next higher dicarboxylic monoamid monoethyl esters. For use in biological
The effects of intracerebroventricular (ICV) beta-carboline carboxylic acid ethyl ester (beta-CCE) and its free acid on the protective effects of diazepam against leptazol- and R05-3663-induced convulsions were investigated in mice and compared with their effects on the antileptazol effect of sodium
OBJECTIVE
Our study focuses on the design and synthesis of a new piperazinic derivate, 4-(1-phenyl-1h-Pyrazol-4-Ylmethyl)-Piperazine-1-Carboxylic Acid Ethyl ester (LQFM008), and evaluation of its anxiolytic-like profile in Swiss mice.
METHODS
LQFM008 was evaluated in a screening test of the central
Two novel N-methyl-D-aspartate (NMDA) antagonists, DL-(E)-2-amino-4-methyl-5-phosphono-3-pentenoic acid CPG 37849 and the corresponding 1-ethyl ester CGP 39551, were tested as anticonvulsants in DBA/2 mice and photosensitive Senegalese baboons, Papio papio. In DBA/2 mice, CGP 37849 is more potent
The behavioural and convulsant effects of imipenem (Imi), a carbapenem derivative, were studied after intraperitoneal (i.p.) or intracerebroventricular (i.c.v.) administration in DBA/2 mice, a strain genetically susceptible to sound-induced seizures. The anticonvulsant effects of some excitatory
The present study compared the behavioral and toxic effects of cocaine and its ethanol derived metabolite, cocaine ethyl-ester (cocaethylene). Both drugs produced qualitatively similar psychomotor stimulant effects. Cocaine and cocaethylene increased locomotor activity in mice, with cocaine
Compounds from both the beta-carboline (BC) and xanthine groups have been suggested to be the natural ligands for benzodiazepine (BZ) receptors. In this study we examined the effects of several BC's and caffeine, 1,3,7-trimethylxanthine, on the binding of 3H-flunitrazepam (3H-FZ) and
The major aim of this study was to elucidate the relationship between nitric oxide (NO) and generalized epilepsy. Mice lacking the neuronal nitric oxide synthase (nNOS) gene (nNOS(-/-)) were used in this study to determine the relationship between nNOS alpha and NO in pentylentetrazole (PTZ)-induced
1-Aminocyclopropanecarboxylic acid is a potent and selective ligand for the glycine modulatory site on the N-methyl-D-aspartate receptor complex. This compound blocks (ED50 234 mg/kg) the convulsions and deaths produced by N-methyl-D-aspartate (125 mg/kg) in a dose dependent fashion. In contrast,
The competitive N-methyl-D-aspartate (NMDA) antagonist DL-2-amino-4-methyl-5-phosphono-3-pentenoic acid (CAS 127910-31-0, 4-methyl-APPA, CGP 37849) and its ethyl ester (CAS 127910-32-1, CGP 39551) potently block NMDA-evoked whole-cell current on mouse spinal neurones in primary dissociated cell
The pivaloyloxymethyl esters 4 and 5 of the amino acid GABA uptake inhibitors guvacine and nipecotic acid, respectively, were synthesized as potential prodrugs. The half-lives of 4 and 5 for conversion into the parent amino acids were determined under approximate physiological conditions in the
The novel anticonvulsant drug D-23129 (N-(2-amino-4-(4-fluorobenzylamino)-phenyl) carbamic acid ethyl ester) was evaluated in the amygdala kindling model of complex partial seizures in rats. D-23129 exerts potent anticonvulsant activity against both focal and generalized seizures in animal models of
