What Is KPV?
KPV is a tripeptide composed of lysine, proline, and valine (Lys-Pro-Val), corresponding to residues 11–13 at the C-terminus of alpha-MSH. Alpha-MSH is a well-studied anti-inflammatory hormone, and research indicates that this short C-terminal sequence retains a substantial part of its anti-inflammatory effect while being much smaller and simpler.
Its small size is part of what makes it interesting as a research tool: it is studied for acting through pathways that do not necessarily depend on the classic melanocortin receptors that full-length alpha-MSH uses.
Studied Mechanism: Intracellular NF-kB Modulation
The recurring theme in KPV research is intracellular anti-inflammatory signaling. Rather than acting only at a cell-surface receptor, KPV is studied for entering cells and interfering with the NF-kB pathway — a master regulator of pro-inflammatory gene expression. By dampening NF-kB activation, it is associated in models with reduced production of pro-inflammatory mediators such as TNF-alpha and certain interleukins.
In gastrointestinal research, KPV is also studied in the context of the PepT1 transporter, which can carry small peptides into intestinal epithelial cells — a route relevant to models of intestinal inflammation.
- KPV is the Lys-Pro-Val C-terminal fragment of alpha-MSH.
- Studied for intracellular action on the NF-kB inflammatory pathway.
- Associated with reduced pro-inflammatory mediators (e.g., TNF-alpha) in models.
- Studied in intestinal-inflammation models via PepT1-mediated uptake.
Research Context And Handling
KPV appears in inflammation, gastrointestinal, and wound-healing research. Common in vitro readouts include NF-kB reporter assays, cytokine panels, and epithelial-barrier models. As with any Research Use Only compound, verified identity and purity, appropriate storage, and interpretation against the primary literature are essential. It is supplied strictly for laboratory research and not for human or animal use.

Frequently Asked Questions
What is KPV?
KPV is a tripeptide of lysine, proline, and valine (Lys-Pro-Val) corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). It retains much of that hormone’s anti-inflammatory activity in a compact form.
How is KPV studied to reduce inflammation?
KPV is studied for acting intracellularly on the NF-kB pathway, a master regulator of pro-inflammatory gene expression, and is associated with reduced pro-inflammatory mediators such as TNF-alpha in models.
Is KPV related to melanotan peptides?
KPV is derived from alpha-MSH but is studied for anti-inflammatory pathways that do not necessarily depend on the melanocortin receptors used by pigmentation-focused MSH analogs. It is a Research Use Only compound.
