GW0742 is primarily used in research settings to study the activation of peroxisome proliferator-activated receptor delta (PPAR-δ). This receptor plays a significant role in regulating genes involved in lipid metabolism and energy homeostasis. Researchers utilize GW0742 to investigate its potential effects on improving metabolic functions, such as enhancing fatty acid oxidation and improving insulin sensitivity. It is also explored for its possible role in reducing inflammation and its impact on cardiovascular health. Additionally, GW0742 is studied in the context of exercise performance, as PPAR-δ activation may influence muscle endurance and energy utilization. Its applications are largely confined to preclinical studies, contributing to a better understanding of metabolic and inflammatory pathways.
