LAU159 is a selective inhibitor of soluble epoxide hydrolase (sEH), primarily used in biomedical research to investigate the therapeutic potential of stabilizing epoxy fatty acids. It is employed in studies on neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases, due to its neuroprotective properties, including prevention of neuronal cell death, promotion of neural function recovery, and reduction of neuroinflammation and tissue damage. Preliminary research also explores its anti-inflammatory effects in other systems, potentially leading to novel treatments for brain-related conditions. While not a standard commercial ingredient, it shows promise in research for skincare applications related to barrier function and inflammation reduction.
