This modified peptide is primarily utilized in research settings to study neurokinin receptors, particularly the NK1 receptor, due to its structural similarity to Substance P. It is often employed in pharmacological studies to investigate receptor binding, signaling pathways, and the role of Substance P in pain, inflammation, and neurogenic responses. Its oxidation-resistant properties make it a valuable tool for in vitro and in vivo experiments where stability is critical. Additionally, it is used in the development of therapeutic agents targeting neurokinin receptors for conditions like chronic pain, migraines, and inflammatory diseases.
