KPV

KPV (alpha-MSH C-terminal tripeptide)

A tripeptide fragment of alpha-MSH, studied for anti-inflammatory signaling independent of pigmentation effects.

What It Is

KPV (lysine-proline-valine) is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH). Researchers use this minimal fragment specifically because it has been reported in the literature to retain alpha-MSH's anti-inflammatory signaling activity without the pigmentation-related effects associated with the full-length hormone, isolating one biological function for study.

As one of the smallest peptides studied in the inflammation literature, KPV is often used as a model compound for probing tripeptide-scale structure-activity relationships.

Mechanism in the Research Literature

Published research has examined KPV's effect on NF-kB signaling, a central transcription-factor pathway in inflammatory gene expression, with studies reporting inhibition of pro-inflammatory cytokine production in cell and tissue models. Research has also explored a PepT1-mediated uptake pathway in intestinal tissue, proposed as a route by which the tripeptide reaches relevant cell populations in gut-inflammation models.

Because of this literature base, KPV is frequently referenced in gastrointestinal and dermal inflammation research contexts as a tool for studying localized anti-inflammatory signaling.

Why Purity Verification Matters Here

At only three amino acids, KPV is chemically simple, but that simplicity raises its own quality-control question: a tripeptide is easier to synthesize incorrectly (wrong stereochemistry, incomplete coupling) without it being obvious on a basic assay. Mass spectrometry confirms exact molecular identity, and HPLC quantifies purity against synthesis byproducts, together ruling out the kind of subtle synthesis error that could otherwise be mistaken for a biological finding.

Third-party tested. Lot-matched. No exceptions.

Every unrl batch is characterized by independent third-party testing before it ships, not just an in-house spec sheet. Each Certificate of Analysis is tied to the lot number printed on the vial, so what you're holding matches a specific, published result rather than a generic average.

  • Independent lab, not manufacturer self-testing
  • HPLC purity + mass spectrometry identity confirmation
  • Lot-specific CoA, matched to the vial in hand
  • Published and searchable in the public COA library
