Used in research as a peptide analog to study neuropeptide function and receptor interactions, particularly in relation to metabolic stability and bioavailability. Its modified structure enhances resistance to enzymatic degradation, making it valuable for investigating peptide-based signaling pathways. Commonly applied in studies of G-protein coupled receptors (GPCRs) due to its affinity for specific neuropeptide receptors. Also explored for potential therapeutic use in neurological and endocrine disorders owing to its ability to cross biological barriers more effectively than natural peptides. Frequently employed in structure-activity relationship (SAR) studies to optimize peptide drug candidates.
