Hori, S.; Kanemitsu, K.; Shimada, J., 1992: Inhibitory activity of am 1155 a newly synthesized quinolone on gamma aminobutyric acid receptor binding a comparative study on convulsant activity of new quinolones
The canola line T45 was genetically engineered to express tolerance to glufosinate ammonium, the active ingredient in phosphinothricin herbicides (Basta®, Rely®, Finale®, and Liberty®). Glufosinate chemically resembles the amino acid glutamate and acts to inhibit an enzyme, called glutamine synthetase, which is involved in the synthesis of glutamine. Essentially, glufosinate acts enough like glutamate, the molecule used by glutamine synthetase to make glutamine, that it blocks the enzymes usual activity. Glutamine synthetase is also involved in ammonia detoxification. The action of glufosinate results in reduced glutamine levels and a corresponding increase in concentrations of ammonia in plant tissues, leading to cell membrane disruption and cessation of photosynthesis resulting in plant withering and death ...

TY - JOUR. T1 - γ-Aminobutyric acid stimulates intrinsic inhibitory and excitatory nerves in the guinea-pig intestine. AU - Krantis, Anthony. AU - Costa, Marcello. AU - Furness, John B.. AU - Orbach, Joseph. PY - 1980/1/1. Y1 - 1980/1/1. N2 - The sites of action of γ-aminobutyric acid (GABA) were examined in preparations of the distal colon and ileum of guinea pigs. GABA caused transient relaxations of the longitudinal and circular muscle of the colon and transient constractions followed by relaxation of the muscle of the ileum. The responses of both parts of the intestine were antagonized by tetrodotoxin and by bicuculline. Nerve-free preparations of the longitudinal muscle of the ileum were not affected by GABA, even in concentrations up to 10−4 g/ml. There was a marked tachyphylaxis of the responses to GABA. Relaxations in response to GABA were not affected by pentolinium or by a combination of phetolamine and propranolol. Contractions in response to GABA were blocked by hyoscine. Neither ...
1. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small population of retinal neurons cultured from human fetuses. 2. Positive staining was restricted to a few cells and could be observed as soon as the cells became attached to the substrate (within 5 hr). It is therefore concluded that the GABA-positive cells are determined prenatally. 3. The GABA-positive cells grow processes during development in culture and remain constant in numbers. These cells have a different morphology from either GFAP-positive cells or serotinin-accumulating cells. 4. It is suggested that the GABA-positive cells in culture are probably amacrine neurones. 5. Cultures of human retinal dissociates may therefore provide an alternative means of studying specific cell types should a constant supply of living human retinas be difficult to obtain. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small
A bacterial pat gene which codes for phosphinothricin acetyltransferase, an enzyme that inactivates glufosinate ammonium through acetylation, was introduced into the HCR-1 line by an interspecific cross with the genetically modified B. napus event T45 (ACS-BNØØ8-2). The inactivation of glufosinate ammonium by the bacterial enzyme confers the herbicide tolerance onto this LMO ...

Koerner and Cotman (1981) initially described that the diacidic amino acid analog l-2-amino-4-phosphonobutyric acid (l-AP4) selectively suppressed glutamate excitations by a presynaptic mechanism in the lateral perforant pathway of the hippocampus. This inhibitory activity of l-AP4 on glutamate excitations was also observed in other preparations, including the mossy fiber synapse, lateral olfactory tract, and spinal cord (seeThomsen, 1997). Until the 1990s, presynaptic inhibition induced by l-AP4 was ascribed to a relatively nebulous l-AP4 receptor. However, with the cloning of the group III mGlu receptors, which Nakanishi (1992) defined by their sensitivity to l-AP4, it was recognized that certain group III mGlu subtypes might be responsible forl-AP4-induced suppression of glutamate release. Current data suggest a role for mGlu7, mGlu8, and possibly mGlu4 as candidates for these presynaptic effects of l-AP4 in the brain (seeThomsen, 1997).. In general, when compared with mGlu7 or mGlu2/3 ...

We show that expression of B. subtilis threonine deaminase, combined with expression of a mutated form of E. coli glutamate dehydrogenase leads to the production of 0.40 ± 0.02 mg/L of (S)-2-aminobutyric acid in shake flask-grown S. cerevisiae cells. The higher production in E. coli achieved by Zhang and co-workers [26] is perhaps due to the special properties of the E. coli strain employed, which can produce 8 g/L l-threonine from 30 g/L glucose. Nevertheless, we rationalize that yeast is indeed a superior production host for (S)-2-aminobutanol production, as it displays higher robustness and considerable tolerance against harsh fermentation conditions. Yeast is also more resistant towards exposure to (S)-2-aminobutanol (Additional file 1: Figure S4). Moreover, the fermentation of yeasts is easily implemented into existing ethanol productions plants, and there are no issues with phage contamination. S. cerevisiae is classified as GRAS (generally regarded as safe) organism; thereby further ...

Using the above system, an OGD dose-response curve was generated first. The culture medium was changed to an exposure medium (glucose-free 37°C Hanks balanced salt solution; Invitrogen Corp.). Culture plates were then placed in a thermoregulated chamber (37°C). The gas phase was altered to 95% N2-5% CO2flowing into the incubated chamber at 10 l/min. Pilot studies were performed which determined that this flow rate caused a reduction of the oxygen concentration to less than 5% within 8 min, after which flow was reduced to 1 l/min for the balance of the exposure interval. Oxygen concentration in the effluent gas was continuously monitored with a medical gas analyzer to assure it remained under 5% for the balance of the exposure interval. Timing of OGD duration was started after the chamber reached 5% O2concentration. OGD was terminated by exchange of the exposure medium to normal oxygenated culture medium and restitution of the ambient atmosphere to 5% CO2-room air at 37°C after return to the ...

γ‐Aminobutyric acid (GABA), the principal inhibitory neurotransmitter in the brain, signals through ionotropic (GABAA/C) and metabotropic (GABAB) receptor systems
Alzheimers disease (AD) is characterized by the transition of amyloid-β (Aβ) monomers into toxic oligomers and plaques. Given that Aβ abnormality typically precedes the development of clinical symptoms, an agent capable of disaggregating existing Aβ aggregates may be advantageous. Here we report that a small molecule, 4-(2-hydroxyethyl)-1-piperazinepropanesulphonic acid (EPPS), binds to Aβ aggregates and converts them into monomers. The oral administration of EPPS substantially reduces hippocampus-dependent behavioural deficits, brain Aβ oligomer and plaque deposits, glial γ-aminobutyric acid (GABA) release and brain inflammation in an Aβ-overexpressing, APP/PS1 transgenic mouse model when initiated after the development of severe AD-like phenotypes ...

N2 - A common function of group III metabotropic glutamate receptors (mGluRs) located at the presynaptic site of a glutamatergic synapse is synaptic depression. Here, we studied synaptic depression mediated by group III mGluR activation at Schaffer collateral-CA1 (SC-CA1) synapses and associational-commissural-CA3 (AC-CA3) synapses by recording field excitatory postsynaptic potentials in the in vitro brain slice preparation. In order to gauge the impact of synaptic depression in chronically epileptic tissue, we compared rats after pilocarpine-induced status epilepticus (post-SE) with control animals. We observed that synaptic transmission at control AC-CA3 ...
Current therapies for Parkinsons disease are able to ameliorate the symptoms in the early stages, however as the disease progresses, they become less effective and patients often develop debilitating side effects. There is currently a significant unmet need for disease modifying or neuroprotective drugs to slow the rate of disease progression and provide long-term symptomatic relief. Novel therapeutics that can provide symptomatic relief whilst attenuating the ongoing neurodegeneration are therefore sought. The targeting of metabotropic glutamate (mGlu) receptors has become a therapeutic focus in recent years. The group III mGlu receptors are the focus of this thesis as they currently hold the most therapeutic promise, with evidence suggesting activation of these receptors not only modulates aberrant neurotransmission in the basal ganglia to provide symptom relief, but also provides neuroprotective effects in the nigrostriatal system through a variety of mechanisms. Recent advances in the ...

Glufosinate is the active ingredient that inhibits plant growth in herbicides that LibertyLink plants are resistant to. These herbicides can come in a variety of forms, including bialaphos, a tripeptide containing two alanine residues and glufosinate. In the case of bialaphos, the peptide is cleaved to produce the active glufosinate.. Glufosinate is very similar in chemical structure to the amino acid glutamate. Because of this structural similarity, glufosinate is able to act as an inhibitor for the enzyme glutamine synthetase, for which glutamate is a substrate. The inhibition of glutamine synthase (GS) results in disruption of the glycolate pathway. Metabolic flux through the pathway is reduced and intracellular levels of pathway intermediates accumulate. One of these intermediates, glyoxylate, is a a strong inhibitor of the key photosynthetic enzyme ribulose bisphosphate carboxylase. Without the activity of this enzyme, plants are unable to fix carbon and rapidly die.. Glufosinate is an ...
Liberty herbicide (glufosinate ammonium) does not kill Pioneer Hi-Breds genetically engineered (GE) Liberty Link corn, even though it is taken up and translocated throughout the plant, because the corn inactivates the herbicide. Genes engineered into the corn produce enzymes in every cell of the corn plant that change glufosinate ammonium into N-acetyl-L-glufosinate, or NAG. When you eat the corn, though, you are also eating NAG that accumulated in the crop with each herbicide application. Some of that NAG may be transformed back into the toxic herbicide in your gut, possibly by bacteria. Two studies with rats showed conversion rates of 1% and 10% respectively, while a study with goats showed conversion of more than one-third. The revived herbicide may travel to kidneys, liver, muscle, fat and milk, where it may be toxic ...
Martin LJ, Oh GH, Orser BA. (2009) Anesthesiology. 111(5):1025-35.. Abstract. BACKGROUND: The memory-blocking properties of general anesthetics have recently received considerable attention because of concerns related to intraoperative awareness and postoperative cognitive dysfunction. The goal of this study was to identify the mechanisms by which γ-aminobutyric acid subtype A receptors that contain the α5 subunit (α5GABAARs) induce memory-blockade by etomidate and a pharmacologic strategy to reverse this impairment.. METHODS: The effects of etomidate and the α5GABAAR-preferring inverse agonist L-655,708 on the plasticity of glutamatergic excitatory transmission in hippocampal slices and behavioral memory for spatial navigational and fear-associated memory tasks were studied in wild-type and null mutant mice for the gene that encodes the α5 subunit (Gabra5-/- mice). Long-term potentiation of field excitatory postsynaptic potentials was induced in CA1 pyramidal neurons following ...
Delirium occurs in 60-80% of ventilated Intensive Care Unit (ICU) patients and is independently associated with prolonged hospital stay, higher cost, a 3-fold increased risk of dying by six months and ongoing neuropsychological dysfunction. Hypothesis: Based on our preliminary work, we hypothesize that standard use of GABA agonist sedatives such as lorazepam and propofol may contribute to ICU delirium and its attendant untoward clinical outcomes. An alternative sedation strategy targeting alpha2 receptors and sparing GABA receptors (dexmedetomidine) might reduce delirium, provide adequate sedation, reduce analgesic requirement, and concurrently improve cognitive performance.. Long-term objective: To standardize and compare different strategies of sedation and analgesia for ventilated ICU patients in order to optimize their clinical outcomes focusing on delirium and the long-term neuropsychological dysfunction of ICU survivors.. Specific Aims:. ...

RESULTS: The GABA signalling system was compromised in islets from type 2 diabetic individuals, where the expression of the genes encoding the α1, α2, β2 and β3 GABA(A) channel subunits was downregulated. GABA originating within the islets evoked tonic currents in the cells. The currents were enhanced by pentobarbital and inhibited by the GABA(A) receptor antagonist, SR95531. The effects of SR95531 on hormone release revealed that activation of GABA(A) channels (GABA(A) receptors) decreased both insulin and glucagon secretion. The GABA(B) receptor antagonist, CPG55845, increased insulin release in islets (16.7 mmol/l glucose) from normoglycaemic and type 2 diabetic individuals ...

Are you stressed? Having trouble sleeping? Suffering from anxiety? You may, like 99.32% of all other Americans, be deficient in magnesium. Not to worry! Fresh off the slow boat from Australia, GABAMAG is here to help.. Among a host of other advantages, magnesium has a calming effect on your bodys nervous system and relaxes the muscles, which in turn will help you to fall asleep easier. A deficiency of magnesium is also sometimes responsible for the nervousness that prevents sleep as well as restless legs syndrome. Magnesium may also improve the length and quality of slow wave sleep. Additionally magnesium binds to and activates GABA receptors. GABA is short for gamma aminobutyric acid, which is your most major relaxing neurotransmitter (brain chemical). Normalisation of brain GABA levels leads to a reduction in stress, anxiety, nervousness, depression and an improvement in insomnia resulting in a more restful nights sleep. ...

The synaptic receptors of ON bipolar neurons are selectively activated by 2-amino-4-phosphonobutyrate, a glutamate analogue. This agent uniquely distinguishes these receptors from other types of excitatory amino acid receptors found in the retina. Various glutamate and aspartate analogues were used to assess the structure-activity characteristics of this receptor. The results suggest that it represents one class of glutamate receptor which can be distinguished by its preferential activation by acidic amino acid analogues that match the extended conformation of glutamate.. ...

The binding of radioactive γ-aminobutyric acid (GABA) to receptor-like sites in mammalian brain membranes was analyzed by computer for comparison with models which might explain the observed apparent heterogeneity of ligand binding. The best fit was obtained with two independent binding sites. Binding was measured by centrifugation, using thoroughly washed, frozen, and thawed membranes without detergent treatment. Assays were carried out at 0° under sodium ion-free conditions which have previously been shown to allow detection only of those binding sites having the chemical specificity and other properties expected of receptor sites for the neurotransmitter GABA. Quantitative analysis of binding curves for several brain regions, subcellular fractions, and species revealed the general presence of two affinity classes for GABA receptors, one with KD Of 13 ± 6 nM (Bmax = 0.33 pmole/mg of protein in bovine cortex) and the other with KD of 300 ± 150 nM (Bmax 1.8 pmole/mg of protein in bovine ...

The expression of these genes are expected to confer resistance to Lepidoptera and Coleoptera, and tolerant to glufosinate herbicide and glyphosate herbicide ...

A Japanese research team has become the first in the world to discover that 2-aminobutyric acid is closely involved in the metabolic regulation of the antioxidant glutathione, and that it can effectively raise levels of glutathione in the body when ingested.
BACKGROUND: AZD3043 is a positive allosteric modulator of the γ-aminobutyric acid type A receptor, with sedative and anesthetic properties. We describe a population pharmacokinetic (PK) model of arterial and venous concentrations of AZD3043 and the pharmacodynamic effects on bispectral index (BIS) in healthy volunteers.. METHODS: Arterial and venous plasma concentrations of AZD3043 and BIS were measured in 2 clinical studies in 125 healthy volunteers, where AZD3043 was given as a 1-minute bolus (1-6 mg/kg), a 30-minute infusion (1-81 mg/kg/h), or 0.8 + 10, 1 + 15, 3 + 30, and 4 + 40 (mg/kg bolus + mg/kg/h infusion for 30 minutes). Population PK/pharmacodynamic analysis was performed with NONMEM.. RESULTS: A recirculatory model, comprising a series of 5 compartments for the transit of drug between venous and arterial plasma, 2 peripheral distribution compartments, and 1 compartment for the nondistributive transit of drug from arterial to venous plasma, described the PK of AZD3043. Systemic ...
