MK-886 (sodium salt) is primarily used in research settings to study its role as a potent and selective inhibitor of 5-lipoxygenase-activating protein (FLAP). It is widely applied in biochemical and pharmacological studies to investigate the leukotriene biosynthesis pathway, which plays a significant role in inflammatory and allergic responses. Researchers utilize MK-886 to explore its potential anti-inflammatory effects and its ability to modulate conditions such as asthma, arthritis, and other inflammatory diseases. Additionally, it serves as a valuable tool in understanding the molecular mechanisms underlying FLAP-mediated processes in cellular and animal models.
