KPV Peptide Research Overview: The Alpha-MSH Fragment

KPV is a very small peptide with a very large research footprint. It is derived from a hormone fragment, and studies have examined it mostly in inflammation-related models.

Key takeaways

• KPV is a tripeptide of lysine, proline and valine.
• It corresponds to the C-terminal end of alpha-MSH.
• Research has focused on inflammatory signaling in cells and in intestinal models.
• Evidence is preclinical and should be interpreted cautiously.

Where KPV comes from

Alpha-melanocyte-stimulating hormone (alpha-MSH) is a melanocortin peptide. KPV matches amino acids 11 to 13 of that molecule. Researchers became interested because this short sequence appeared to keep some of the anti-inflammatory signaling associated with the full hormone.

What has been studied

• Effects on inflammatory signaling pathways in cultured cells.
• Gut inflammation in animal models, including studies on delivery to intestinal tissue.
• Comparisons with the full alpha-MSH peptide and with other melanocortin fragments.

How it differs from other melanocortin peptides

Compounds such as Melanotan-1 and Melanotan-2 act on melanocortin receptors in different ways. For a comparison, see our article on Melanotan-1 versus Melanotan-2. KPV is often studied for its inflammation-related effects rather than pigmentation.

Limits of the evidence

Most findings come from cells and animals. Mechanisms are still being worked out, and results vary by model.

Frequently asked questions

Why is such a small peptide interesting?

Short sequences are easy to synthesize and study, and KPV appears to retain an activity of a much larger parent molecule.

Is KPV approved as a medicine?

No. It is supplied for laboratory research only.

How should it be stored?

Cold, dry and protected from light. See our storage guide.

Handling and documentation

As with any peptide, document lot numbers, storage conditions and preparation steps so that results can be reproduced.
