1.MECHANISM OF ACTION

This analog functions as a potent agonist for NPY receptors, primarily targeting the Y1, Y2, and Y5 subtypes. The substitution of the native L-tryptophan with its D-isomer at position 32 confers exceptional resistance to enzymatic breakdown by proteases, significantly prolonging its in vitro and in vivo half-life.

2.PRODUCT INDICATIONS

This product is indicated for advanced research in cardiovascular physiology, neuropharmacology, and metabolic disorders where sustained NPY receptor activation is required. Key applications include: investigating long-term effects of NPY signaling in models of hypertension and obesity, studying the role of NPY in stress and anxiety over extended periods, serving as a stable reference agonist in chronic functional assays, and as a key compound in structure-activity relationship (SAR) studies to develop protease-resistant peptide therapeutics.

3.CLINICAL EFFICACY OF PRODUCT

[D-Trp³²]-NPY (porcine) is a specialized research probe, not a clinical drug. Its efficacy is demonstrated in preclinical studies as a robust tool for investigating the consequences of prolonged NPY receptor stimulation. The incorporation of a D-amino acid represents a proven strategy in medicinal chemistry to overcome the rapid degradation of natural peptides.
