BAY-678 is primarily utilized in the field of biomedical research, particularly in the study of cancer biology. It functions as a potent and selective inhibitor of the enzyme monoacylglycerol lipase (MAGL), which plays a significant role in lipid metabolism and signaling pathways. By inhibiting MAGL, BAY-678 helps researchers investigate the enzyme's impact on tumor growth, metastasis, and the tumor microenvironment. This compound is also valuable in exploring the potential therapeutic benefits of MAGL inhibition in various cancers, as it may disrupt the production of pro-tumorigenic signaling lipids. Additionally, BAY-678 is used in preclinical studies to better understand the role of MAGL in neurological disorders and inflammatory processes, contributing to the development of targeted therapies.
