DGAT1-IN-1 is primarily used in research settings to study the role of diacylglycerol O-acyltransferase 1 (DGAT1) in lipid metabolism. It acts as a selective inhibitor of DGAT1, an enzyme involved in the synthesis of triglycerides. By inhibiting DGAT1, researchers can investigate its impact on fat storage, energy balance, and metabolic disorders such as obesity and diabetes. This compound is also utilized in preclinical studies to explore potential therapeutic strategies for conditions related to excessive lipid accumulation. Additionally, DGAT1-IN-1 helps in understanding the broader physiological functions of DGAT1 in cellular processes and its potential as a drug target.
