Effective inhibitor of AMPA receptor calcium influx in neurons.
By Karthik Krishnamurthy on 11/15/2021
Assay Type: In Vitro
Species: Rat
Cell Line/Tissue: Cultured rat motor neurons

Preincubated 40 micromolar of GYKI 52466 for 10 minutes. The image shows the peak fluorescence intensity of fura2-am up on AMPA stimulation. GYKI 52466 efficiently inhibits AMPA receptor-mediated calcium influx.

Great results using GYKI in electrophysiology experiments.
By Anonymous on 08/21/2018
Assay Type: Ex Vivo
Species: Mouse
Cell Line/Tissue: acute hippocampal brain slice

We use GYKI 52466 dihydrochloride at 10uM to inhibit AMPA receptors during our electrophysiology experiments. This allows us to isolate and study the effects of manipulations on other glutamate receptors. In the set of experiments we used this product for we were examining Kainate receptor properties and so the GYKI was used in conjunction with an NMDAR antagonist.

Addiction Poster

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.


Alzheimer's Poster

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide.

Major depressive disorder is characterized by depressed mood and a loss of interest and/or pleasure. Updated in 2015 this poster highlights presynaptic and postsynaptic targets for the potential treatment of major depressive disorder, as well as outlining the pharmacology of currently approved antidepressant drugs.


Epilepsy Poster

Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.

Learning & Memory

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.


Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.


Parkinson's Poster

Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.


Schizophrenia Poster

Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease.
