GW7647 is primarily used in research settings as a potent and selective agonist for the peroxisome proliferator-activated receptor alpha (PPARα). It is widely utilized in studies focused on understanding lipid metabolism, inflammation, and glucose homeostasis. Researchers employ GW7647 to investigate its effects on fatty acid oxidation, which is crucial in conditions like obesity, diabetes, and cardiovascular diseases. Additionally, it serves as a tool compound to explore the role of PPARα in regulating gene expression related to energy balance and metabolic disorders. Its application extends to preclinical models to assess potential therapeutic strategies for metabolic syndromes and liver diseases.
