All excitatory amino acid antagonists studied: diethyl esters of aspartic (DEEA) and glutamic (DEEG) acids, 2-amino-3-phosphono-propionic acid (APPA) and 2-amino-4-phosphono-butanoic acid (APBA), diminished the amplitude of excitatory postsynaptic potentials (EPP) of the locust (Locusta migratoria
OBJECTIVE
To determine if a small ultraviolet emitting diode (UV LED) could release sufficient gamma-aminobutyric acid (GABA) from a caged precursor to suppress paroxysmal activity in rat brain slices.
METHODS
Electrophysiologic recordings were obtained from rat brain slices bathed with caged GABA:
Understanding the overall and common metabolic changes of seizures can provide novel clues for their control and prevention. Here, we aim to investigate the global metabolic feature of serum for three types of seizures.
We recruited 27 patients who had experienced a seizure within 48h (including 11
Published data on the mechanisms involved in the action of levetiracetam (LVT, 2S-(oxo-1-pyrrolidinyl)butanoic acid amide), a widely used agent for the adjunctive therapy of partial epilepsy of different genesis, have been analyzed. A unique profile of the anticonvulsant action of LVT was already
By use of rat liver or brain homogenate supernatants containing microsomes and/or mitochondria, it was found that the prototype GABAergic prodrug [3-(p-chlorophenyl)pyrrolidine (1)] underwent a series of alpha-oxidation transformations to a pair of amino acid metabolites and a pair of lactam
Recently, we developed the fatty acid-binding protein 3 (FABP3) ligand MF1 (4-(2-(1-(2-chlorophenyl)-5-phenyl-1H-pyrazol-3-yl)phenoxy) butanoic acid) as a therapeutic candidate for α-synucleinopathies. MF1 shows affinity towards γ-aminobutyric acid type-A (GABAA) receptor, but its effect
Fragile X syndrome is an X-linked disorder caused by the inactivation of the FMR1 gene, with symptoms ranging from impaired cognitive functions to seizures, anxiety, sensory abnormalities, and hyperactivity. Although fragile X syndrome is considered a typical Mendelian disorder, we have recently
The purpose of this study was to synthetize the focused library of 34 new piperazinamides of 3-methyl- and 3,3-dimethyl-(2,5-dioxopyrrolidin-1-yl)propanoic or butanoic acids as potential new hybrid anticonvulsants. These hybrid molecules join the chemical fragments of well-known antiepileptic drugs
A series of N-substituted-1,3-isoindolinedione derivatives (2-16) were synthesized for the purpose of defining the effect of N-substitution on the anticonvulsant activity of these derivatives. The target compounds (2-16) were obtained by condensation of phthalic anhydride with the corresponding
Schiff bases of gamma-aminobutyric acid (gammaAbu) and gamma-aminobutyramide (gammaAbuNH2) were prepared and tested for anticonvulsant and gammaAbu mimetic activity. 4-[[(4-Chlorophenyl)(5-fluoro-2-hydroxyphenyl)methylene]amino]butanoic acid monosodium salt (4) and
The purpose of this study was to synthesize the library of 33 new N-benzyl-2-(2,5-dioxopyrrolidin-1-yl)propanamides, 2-(3-methyl-2,5-dioxopyrrolidin-1-yl)propanamides, and 2-(2,5-dioxopyrrolidin-1-yl)butanamides as potential new hybrid anticonvulsant agents. These hybrid molecules join the chemical
