This peptide is primarily used in research settings to study the role of neurokinin receptors, particularly the NK2 receptor subtype. It acts as a selective agonist, allowing scientists to investigate the physiological and pathological processes mediated by these receptors, such as smooth muscle contraction, inflammation, and pain signaling. Its application extends to understanding gastrointestinal motility disorders, as NK2 receptors are involved in regulating intestinal muscle activity. Additionally, it serves as a tool in pharmacological studies to develop and test potential therapeutic agents targeting neurokinin pathways.
