Introduction of 58002-62-3 :

Kainic acid hydrate is a potent excitotoxic agent. Kainic acid hydrate also is an agonist for a subtype of ionotropic glutamate receptor. Kainic acid hydrate induces seizures[1][2]. In Vivo:Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Kainic acid can be used to create epilepsy models and can be administered systemically, into the hippocampus, or amygdala, and is reproducible in various species. The systemic Kainic acid model closely mimics the manifestations of human temporal lobe epilepsy. When injected at a dose of 5 nM into the neostriatum, substantia nigra, or cerebellum, over half of the Kainic acid disappears from the injection site and brain within 0.5 hours, with radioactivity detected in other brain regions at concentrations lower than 7 pmol/mg[3][4][6].

Induction of epilepsy model[5]
Background
Kainic acid, an analog of L-glutamate and an ionotropic KA receptor agonist, can damage hippocampal pyramidal neurons.
Specific Modeling Methods
Mice: C57BL/6J • male • 7 weeks old • 22 g body weight
Administration: 10 μg in 5 μL • i.c.v.
Note
(1) The right lateral brain ventricle is localized with a stereotactic instrument.
(2) After the operation, skin was sutured, and keep the mice under a warming place until they wake up.
(3) 48 hours after lateral ventricle injection, the mice are anaesthetized using Isoflurane and then sequentially intracardially perfused with saline and PFA (4%, 30 mL). Rapidly remove The mouse brain processed for paraffin embedding or frozen sections.
Modeling Indicators
Electroencephalogram (EEG) recording: Had higher local maximal amplitude and reduced spike frequency compared to the control group.
Histology analysis: Showed Triangulated pyknotic nuclei and cytoplasmic shrinkage in the hippocampal neuron, and induced neuronal loss.
Opposite Product(s): Sitagliptin (HY-13749)
