Atglistatin is primarily used in research settings to study metabolic processes and lipid metabolism. It functions as a selective inhibitor of adipose triglyceride lipase (ATGL), an enzyme crucial for breaking down stored fats into free fatty acids. By inhibiting ATGL, Atglistatin helps researchers investigate the role of lipid metabolism in conditions such as obesity, diabetes, and cardiovascular diseases. It is also utilized to explore the potential therapeutic benefits of modulating lipid metabolism in metabolic disorders. Additionally, Atglistatin aids in understanding the mechanisms of energy homeostasis and fat storage at the cellular level, contributing to advancements in metabolic and pharmacological research.
