What is KPV?
KPV is a compact tripeptide made from lysine, proline, and valine. It corresponds to the C-terminal three-residue sequence of alpha-melanocyte-stimulating hormone, giving researchers a small, clearly defined fragment to study independently.
Preclinical work has explored KPV in cellular models of inflammatory signaling, epithelial transport, and cytokine response. Its small size does not eliminate the need for identity testing: a correct three-residue sequence and clean chromatographic profile still matter.
How It Works
Uses a three-residue signal: KPV isolates the Lys-Pro-Val end sequence of alpha-MSH for focused research.
Interacts with cellular transport systems: Intestinal research models have examined uptake involving the PepT1 peptide transporter.
Modulates inflammatory pathways: Cell studies report reduced NF-κB and MAPK activation and changes in downstream cytokine signaling.
