New AMPA antagonists in epilepsy
Expert Opinion on Investigational Drugs, 2012Epilepsy is a common neurological disorder; however, its therapy is not satisfactory because a large number of patients suffer from refractory seizures and/or has a low quality of life due to antiepileptic drug (AED) side effects. Glutamate is the major excitatory neurotransmitter in the brain, AMPA receptors (AMPARs) represent a validated target for ...

AMPA Receptor Trafficking and GluR1
Science, 2005In their Research Article “Postsynaptic receptor trafficking underlying a form of associative learning” (1 Apr., p. 83), S. Rumpel et al. draw the important conclusions that “encoding of memories in the lateral amygdala is mediated by AMPA receptor trafficking” and that “synaptic incorporation of AMPARs is necessary for learning.” The key experiment ...

2,3-Benzodiazepine AMPA Antagonists
Restorative Neurology and Neuroscience, 1998The 2,3-benzodiazepine GYKI 52466 (1-(4-aminophenyl)-4 methyl-7,8-methylenedioxy-5H-2,3-benzodiazepine) and its analogues represent a family of selective AMPA antagonists. They modulate AMPA channel functions through an allosteric site on the receptor, which is probably different from the ones involved in the actions of cyclothiazide and aniracetam ...

Phosphonate quinoxalinedione AMPA antagonists
Restorative Neurology and Neuroscience, 2000In the Western world, over 350,000 deaths and $30 billion in medical costs are attributed annually to stroke. Head and spinal cord trauma cause an estimated 250,000 deaths annually and result in medical costs of $15 billion. Although stroke and head/spinal cord trauma are leading causes of disability and death in humans, no adequate neuroprotective ...

Sensitivity of AMPA receptors to pentobarbital
European Journal of Pharmacology: Molecular Pharmacology, 1994The inhibitory effects of pentobarbital on various AMPA receptors expressed (GluR1, GluR3, GluR1/3, GluR1/2, and GluR2/3) in Xenopus oocytes were examined. Combinations of AMPA receptor subunits that included GluR2 demonstrated a much higher sensitivity to blockade by this barbiturate and the apparent co-operativity of the interaction of pentobarbital ...

The AMPA receptors of auditory neurons
Hearing Research, 2000The ionotropic glutamate receptor (GluR) subtype known as the AMPA receptor, which mediates rapid excitatory synaptic transmission in many regions of the nervous system, is composed of four different protein subunits, termed GluRs 1-4. The functional properties of each AMPA receptor are determined by the relative levels of GluRs 1-4 and by post ...
