Dermorphin is primarily used in scientific research due to its potent analgesic properties. It is often studied for its ability to bind to mu-opioid receptors, making it a valuable tool in understanding pain mechanisms and developing new pain-relief medications. In animal studies, it has been employed to explore the effects of opioid receptor activation and to model pain responses. Additionally, its unique structure and high potency make it a subject of interest in peptide chemistry and drug design. However, its use is strictly limited to controlled research settings due to its strong opioid effects and potential for misuse.
