L-NASPA (CAS 155915-46-1)

L-NASPA, or L-(−)-N-(3-Hydroxy-3-carboxy-1-oxopropyl)-aspartic acid, is an intriguing compound in biochemical research due to its role as a specific inhibitor of the enzyme glutaminase. Glutaminase is involved in the conversion of glutamine to glutamate, a key step in cellular nitrogen metabolism and an important process in the regulation of neurotransmitter levels. L-NASPA′s inhibition of glutaminase provides a useful tool for studying metabolic pathways in cancer cell metabolism, as many cancer cells rely on glutaminase activity for growth and survival. This compound allows researchers to dissect the role of glutaminase in the regulation of the tricarboxylic acid cycle and its influence on cellular bioenergetics. Additionally, L-NASPA is employed in neuroscience research to understand the modulation of glutamate levels in the brain, thereby elucidating the mechanisms underlying excitotoxicity and synaptic transmission. Its precise inhibitory action aids in studying the metabolic dependencies of various cell types and their responses to glutaminase inhibition. By utilizing L-NASPA, researchers can explore the complexities of glutamine metabolism, providing insights into both fundamental biochemical processes and the metabolic adaptations of cells under different physiological and pathological conditions.
