L-Quisqualic Acid is primarily used in neuroscience research as a potent agonist for certain glutamate receptors, particularly AMPA and metabotropic glutamate receptors. It is employed in studies to understand synaptic transmission, neuronal excitability, and the role of glutamate in brain function. Additionally, it is utilized in experiments exploring neurotoxicity and the mechanisms underlying neurodegenerative diseases. Its ability to selectively activate specific receptor subtypes makes it a valuable tool for investigating receptor pharmacology and signaling pathways in the central nervous system.
