}Excitatory neurotransmission at many CNS synapses depends upon AMPA-type glutamate receptors. Derangements in AMPA receptor-mediated synaptic transmission may be a contributing factor in neurological and neurodegenerative diseases and could be a target for therapeutic intervention. Drugs that positively modulate AMPA receptors by reducing AMPA receptor desensitization and/or slowing AMPA receptor deactivation, such as thiazide derivative (cyclothiazide, diazoxide, IDRA 21) and benzoylpiperidine…

Therapeutic potential of positive AMPA receptor modulators in the treatment of neurological disease
- Biology, PsychologyExpert opinion on investigational drugs
- 2000
The clinical utility of positive AMPA modulators will be dependent upon understanding the role of AMPA receptors in certain neurological disorders, identifying receptor subtypes involved in specific neurological disorders and developing drugs with selective actions upon specific AMPA receptor properties that also possess receptor subtype specificity.

Evidence for advantages of AMPA receptor antagonists over N-methyl-D-aspartate (NMDA) receptor antagonists for symptomatic treatment of neurological and psychiatric conditions, and for minimising neuronal loss occurring after acute neurological diseases, are shown in animal models.
Investigation of the Functional Effects of Two Novel Ampakines in the CNS
- Biology

The semi-quantitative [C]-2-deoxyglucose model was reproducible and accurate and thus could be further used to investigate the effects of the novel Ampakines, Org 26576 and Org 24448, on cerebral function.
Positive modulators of the AMPA receptor
- Medicine, Biology

The number of structural classes of compounds reported in the patent literature as positive modulators of the AMPA receptor is expanding from the earlier benzoyl piperidine (aniracetam) and thiazide (cyclothiazide, diazoxide) chemical series.
Enhanced AMPA receptor function promotes cerebellar long-term depression rather than potentiation.

The findings show that ampakines selectively modify the LTP-LTD balance depending on the brain area and type of synapse, and may provide tools for the targeted regulation of synaptic memories.
Chloride Influx Aggravates Ca2+-Dependent AMPA Receptor-Mediated Motoneuron Death
- BiologyThe Journal of Neuroscience
- 2003
The Cl- influx during AMPA receptor stimulation was enhanced by coadministration of GABA, which resulted in an increased Ca2+ influx and an enhanced cell death, suggesting that concomitant GABAergic stimulation may aggravate excitotoxic motoneuron death.

Although cultured astrocytes express functional glutamate receptors, they are generally resistant to excitotoxic cell death, and the extent of AMPA receptor desensitization may be an important determinant of glial vulnerability to excITotoxic insults.

It is suggested that “switching off” GluR2 expression in CAI after an ischemic insult is translated into formation of new AMPA receptors lacking the GLUR2 subunit, which increases AMPA-receptor-mediated Ca2+ entry in response to endogenous glutamate and enhances glutamate pathogenicity in this region.

It is demonstrated that glutamate plus IDRA 21 kills cultured rat hippocampal neurons by AMPA receptor activation, and, in vivo, 12 and 24 mg/kg of IDRA21 given orally increases CA1 neuron loss produced by 10 minutes of global ischemia.
