About this compound

KPV is the C-terminal tripeptide Lys-Pro-Val corresponding to residues 11–13 of alpha-melanocyte-stimulating hormone. It has been investigated in preclinical models involving inflammatory signaling, intestinal epithelial transport, cytokine output, antimicrobial activity and epithelial repair. The available literature is predominantly preclinical and does not establish clinical safety or efficacy.

The KPV tripeptide

Three amino acids with a focused research profile.

KPV is composed of lysine, proline and valine. Its compact structure is associated with α-MSH-derived anti-inflammatory research and transporter-mediated uptake studies.

Sequence

Lys-Pro-Val

The C-terminal tripeptide corresponding to α-MSH residues 11–13.

Length

3 residues

A short peptide studied in cellular transport, cytokine and epithelial models.

Primary research context

Inflammatory signaling

Preclinical literature has examined NF-κB, MAP-kinase and pro-inflammatory cytokine output.

Published research observations

Published preclinical research observations.

The following points summarize published laboratory and animal-model findings. They should not be interpreted as clinical outcomes.

Inflammatory signalingNF-κB

Pathway suppression research

KPV has been investigated for suppression of NF-κB and MAP-kinase signaling and reduced production of pro-inflammatory cytokines in experimental models.

Cellular transportPepT1

Tripeptide uptake

Research in intestinal models has examined uptake through the PepT1 di- and tripeptide transporter.

Epithelial modelsRepair

Re-epithelialization research

Published corneal and epithelial studies have explored wound-closure and nitric-oxide-associated responses.

Transport researchPepT1-mediated uptake
Epithelial researchMigration and repair
Mechanism map

Three connected research pathways.

The animated map follows KPV from peptide transport to intracellular inflammatory signaling and epithelial research endpoints.

TRANSPORT · PepT1

Peptide-transporter-mediated uptake

KPV has been studied as a substrate for PepT1 in intestinal epithelial and immune-cell research.

SIGNALING · NF-κB / MAPK

Inflammatory pathway modulation

Preclinical findings describe reduced activation of NF-κB and MAP-kinase signaling and lower inflammatory cytokine output.

EPITHELIUM · REPAIR

Epithelial migration and repair models

KPV has been investigated in corneal and intestinal epithelial models involving migration, barrier response and re-epithelialization.

Research landscape

What distinguishes KPV.

KPV is presented here as a defined tripeptide rather than a blend or full-length melanocortin hormone.

Source relationship

α-MSH fragment

KPV corresponds to the C-terminal residues 11–13 of α-MSH.

Size

Tripeptide

Its three-residue structure is substantially smaller than the full α-MSH peptide.

Research focus

Inflammation and epithelium

The literature emphasizes cytokine signaling, intestinal transport and epithelial models.

Pharmacokinetics

Exposure is model- and route-dependent.

KPV is a small tripeptide, but a universal half-life or validated dosing interval should not be claimed without route-, matrix- and model-specific data.

Molecular compactnessTripeptide
Transport dependenceModel-specific
Clinical PK evidenceNot established
Peptide length3 aa

Compact molecular format

Short peptide length influences transport and degradation but does not by itself establish in-vivo stability.

Transport mechanismPepT1

Carrier-mediated uptake research

Transporter expression and experimental matrix can strongly affect observed uptake.

Clinical statusPreclinical

No validated human PK profile

Published KPV work is primarily laboratory and animal research.
