CAY10505 is primarily used in biomedical research as a selective inhibitor of 15-lipoxygenase (15-LOX), an enzyme involved in the metabolism of polyunsaturated fatty acids and the production of bioactive lipid mediators. Its ability to modulate 15-LOX activity makes it a valuable tool in studying inflammatory processes, oxidative stress, and related diseases such as atherosclerosis, neurodegenerative disorders, and certain cancers. Researchers use CAY10505 to investigate the role of 15-LOX in cellular signaling pathways and to evaluate the therapeutic potential of targeting this enzyme. It is commonly applied in in vitro and in vivo models to assess anti-inflammatory and cytoprotective effects, particularly in systems where lipid peroxidation contributes to disease progression.
