Structure-epileptogenicity relationship of quinolones with special reference to their interaction with gamma-aminobutyric acid receptor sites.
The relationship between the chemical structure and epileptogenic activity of quinolones was investigated. When the quinolones were administered intravenously to mice concomitantly with oral biphenylacetic acid, a major metabolite of the nonsteroidal antiinflammatory drug fenbufen, enoxacin, norfloxacin, ciprofloxacin, and pipemidic acid, which have an unsubstituted piperazine moiety at the 7 p...
متن کاملP146: Gamma Aminobutyric Acid (GABA) and its Alterations in Stress
Gamma aminobutyrate (GABA) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. Mechanisms by which GABA may facilitate these responses to stress are metabolic and/or mechanical disruptions. Environmental stresses increase GABA accumulation through cytosolic acidification, induce an acidic pH-dependent activation of glutamate...
متن کاملGamma-Aminobutyric Acid (GABA) Monograpy
Introduction Gamma-aminobutyric acid (GABA) is a major neuro transmitter widely distributed throughout the central nervous system (CNS). Because too much excitation can lead to irritability, restlessness, insomnia, seizures, and movement disorders, it must be balanced with inhibition. GABA – the most important inhibitory neurotransmitter in the brain – provides this inhibition, acting like a “b...
متن کاملThe interactions of hexachlorocyclohexane isomers with human gamma-aminobutyric acid(A) receptors expressed in Xenopus oocytes.
The effects of gamma-hexachlorocyclohexane (gamma-HCH) and its alpha, beta and delta isomers on the gamma-aminobutyric acid (GABA) responses of human alpha1beta3gamma2S and alpha6beta3gamma2S GABA(A) receptors expressed in Xenopus oocytes were examined by conventional two-electrode voltage-clamp techniques. Gamma-HCH induced partial inhibition of EC50 GABA responses, whereas the alpha and delta...
متن کاملMetabolism and functions of gamma-aminobutyric acid.
Gamma-aminobutyric acid (GABA), a four-carbon non-protein amino acid, is a significant component of the free amino acid pool in most prokaryotic and eukaryotic organisms. In plants, stress initiates a signal-transduction pathway, in which increased cytosolic Ca2+ activates Ca2+/calmodulin-dependent glutamate decarboxylase activity and GABA synthesis. Elevated H+ and substrate levels can also st...
