CAY10444 is primarily used in biochemical and pharmacological research as a selective agonist for peroxisome proliferator-activated receptor delta (PPARδ). It activates PPARδ signaling pathways, making it a valuable tool for studying metabolic regulation, including fatty acid oxidation, energy homeostasis, and insulin sensitivity. Researchers use CAY10444 to investigate conditions such as obesity, type 2 diabetes, and metabolic syndrome in cellular and animal models. It also supports studies on muscle endurance and exercise mimetics due to its role in enhancing oxidative muscle fibers. Its application is largely confined to laboratory research and drug development, with no current clinical use in humans.
