Used in biochemical and pharmacological research to study the role of the delta-opioid receptor (δ-opioid receptor), particularly in pain modulation, inflammation control, and central nervous system function. It has potential as a lead compound for developing treatments for chronic pain without the addictive side effects of other opioids. Additionally, it is used to investigate cardiovascular effects, such as protecting cardiac muscle from ischemia-induced damage, and may play a role in neuronal protection in certain neurological conditions. As a selective agonist, it is valuable in neuropharmacology for exploring analgesic drugs and in assays to evaluate receptor binding and signal transduction pathways.
