quisqualic acid profile

Quisqualic acid is a potent agonist of the AMPA subtype of glutamate receptors, which are essential for excitatory neurotransmission in the central nervous system. It is a natural product isolated from the seeds of the plant Quisqualis indica. Its synthesis involves a multistep process, starting from a readily available compound like 4-hydroxyquinoline. Quisqualic acid has been extensively studied for its potential to enhance cognitive function and its role in neurological disorders such as Alzheimer's disease and stroke. It has also been shown to have anti-inflammatory and neuroprotective properties. However, its use in clinical settings is limited due to its high toxicity and its rapid degradation in the body. Researchers continue to explore the potential of quisqualic acid as a pharmacological tool for understanding the role of glutamate receptors in neuronal function and for developing novel therapeutic agents.'

Quisqualic Acid: An agonist at two subsets of excitatory amino acid receptors, ionotropic receptors that directly control membrane channels and metabotropic receptors that indirectly mediate calcium mobilization from intracellular stores. The compound is obtained from the seeds and fruit of Quisqualis chinensis. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Absence Seizure Disorder [description not available]	1.98	1
Epilepsy, Absence A seizure disorder usually occurring in childhood characterized by rhythmic electrical brain discharges of generalized onset. Clinical features include a sudden cessation of ongoing activity usually without loss of postural tone. Rhythmic blinking of the eyelids or lip smacking frequently accompanies the SEIZURES. The usual duration is 5-10 seconds, and multiple episodes may occur daily. Juvenile absence epilepsy is characterized by the juvenile onset of absence seizures and an increased incidence of myoclonus and tonic-clonic seizures. (Menkes, Textbook of Child Neurology, 5th ed, p736)	1.98	1
Absence Status [description not available]	2.38	2
Status Epilepticus A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.
