Tripeptide (Lys-Pro-Val); C-terminal fragment of alpha-melanocyte-stimulating hormone (alpha-MSH); melanocortin-derived anti-inflammatory peptide

KPV

Investigationalaka Lysine-proline-valine, Lys-Pro-Val, alpha-MSH (11-13), KPV tripeptide

KPV is the C-terminal tripeptide of alpha-MSH that retains much of the parent hormone's anti-inflammatory activity while being more stable. Its evidence base is preclinical (cell and rodent inflammatory-disease models); it is unapproved and, in the US, has been the subject of FDA compounding review.

Mechanism

KPV is reported to enter cells (in the gut partly via the PepT1 di/tripeptide transporter) and inhibit the NF-kappaB pathway, lowering pro-inflammatory cytokines (e.g., TNF-alpha, IL-6) and reactive oxygen species; some activity is also attributed to melanocortin receptors (MC1R/MC3R). These mechanisms are established mainly in vitro and in animal models, not in controlled human studies.

Regulatory Status by Region

  • United States (FDA)Not FDA-approved; was on the 503A Category 2 list, removed April 2026, and scheduled for Pharmacy Compounding Advisory Committee review (July 2026). On July 23, 2026, the committee voted 8-6, with one abstention, to recommend KPV (for wound treatment and inflammatory conditions) for the Section 503A Bulk Drug Substances List; the vote is advisory and non-binding, and the FDA had not made a final decision as of publication.
  • Australia (TGA)No registered/approved product; an unapproved therapeutic substance.
  • European Union (EMA)No EMA marketing authorisation.
  • WADANot specifically named on the Prohibited List.

Common Questions

What is KPV?
KPV is a three-amino-acid fragment of the hormone alpha-MSH studied for anti-inflammatory effects in laboratory and animal models of colitis, dermatitis and wound healing. It has no completed human clinical trials and is not approved as a medicine anywhere; evidence remains preclinical.
Is KPV approved for medical use?
KPV is investigational: it is being studied in clinical research and is not an approved medicine. United States (FDA): Not FDA-approved; was on the 503A Category 2 list, removed April 2026, and scheduled for Pharmacy Compounding Advisory Committee review (July 2026). On July 23, 2026, the committee voted 8-6, with one abstention, to recommend KPV (for wound treatment and inflammatory conditions) for the Section 503A Bulk Drug Substances List; the vote is advisory and non-binding, and the FDA had not made a final decision as of publication. European Union (EMA): No EMA marketing authorisation. Australia (TGA): No registered/approved product; an unapproved therapeutic substance.
How does KPV work?
KPV is reported to enter cells (in the gut partly via the PepT1 di/tripeptide transporter) and inhibit the NF-kappaB pathway, lowering pro-inflammatory cytokines (e.g., TNF-alpha, IL-6) and reactive oxygen species; some activity is also attributed to melanocortin receptors (MC1R/MC3R). These mechanisms are established mainly in vitro and in animal models, not in controlled human studies.
Is KPV legal in Australia?
KPV in Australia (TGA): No registered/approved product; an unapproved therapeutic substance.
Is KPV banned in sport?
KPV under the World Anti-Doping Agency (WADA) code: Not specifically named on the Prohibited List.
