Description

Application

CNQX has been used:

as an α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate blocker to study its effects on cytoneme formation in pluripotent embryonic stem cells (pESCs)
glutamate blocker to reduce the synaptic input during current-clamp recordings in central antennal lobe neurons
as a non-N-methyl-D-aspartate (NMDA) receptor blocker to study its effects on the heart rate in rats

Biochem/physiol Actions

Potent, competitive AMPA/kainate glutamate receptor antagonist.

VGLUT2 Trafficking Is Differentially Regulated by Adaptor Proteins AP-1 and AP-3.

Haiyan Li et al.

Frontiers in cellular neuroscience, 11, 324-324 (2017-11-11)

Release of the major excitatory neurotransmitter glutamate by synaptic vesicle exocytosis depends on glutamate loading into synaptic vesicles by vesicular glutamate transporters (VGLUTs). The two principal isoforms, VGLUT1 and 2, exhibit a complementary pattern of expression in adult brain that

Chronic intermittent hypoxia impairs heart rate responses to AMPA and NMDA and induces loss of glutamate receptor neurons in nucleus ambiguous of F344 rats.

Binbin Yan et al.

American journal of physiology. Regulatory, integrative and comparative physiology, 296(2), R299-R308 (2008-11-21)

Chronic intermittent hypoxia (CIH), as occurs in sleep apnea, impairs baroreflex-mediated reductions in heart rate (HR) and enhances HR responses to electrical stimulation of vagal efferent. We tested the hypotheses that HR responses to activation of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) and

The paracetamol metabolite N-acetylp-benzoquinone imine reduces excitability in first- and second-order neurons of the pain pathway through actions on KV7 channels.

Sutirtha Ray et al.

Pain, 160(4), 954-964 (2019-01-03)

Paracetamol (acetaminophen, APAP) is one of the most frequently used analgesic agents worldwide. It is generally preferred over nonsteroidal anti-inflammatory drugs because it does not cause typical adverse effects resulting from the inhibition of cyclooxygenases, such as gastric ulcers. Nevertheless
