MJ33 lithium salt is primarily used in research settings to study the role of phospholipase A2 (PLA2) enzymes in various biological processes. It acts as a selective inhibitor of calcium-independent PLA2 (iPLA2), making it a valuable tool for understanding the enzyme's function in cellular signaling, inflammation, and lipid metabolism. Researchers utilize it to investigate the impact of iPLA2 inhibition on conditions such as neurodegenerative diseases, cardiovascular disorders, and diabetes. Its application extends to exploring the enzyme's role in membrane remodeling and apoptosis. Additionally, MJ33 lithium salt is employed in biochemical assays to dissect the pathways involving lipid mediators and their contribution to disease mechanisms.
