KPV

unknown risk

Also: Lysine-Proline-Valine · alpha-MSH fragment · KdPT

Preliminary Research Only

KPV is a tripeptide fragment of alpha-melanocyte stimulating hormone (alpha-MSH) representing its C-terminal sequence. It has demonstrated potent anti-inflammatory properties in gut tissue, making it a focus of research for inflammatory bowel disease.

Reported Benefits

Gut Anti-inflammation

Preliminary 12 studies

In vitro and animal studies show inhibition of NF-kB and reduced inflammatory cytokines in gut tissue.

IBD (Animal)

Preliminary 8 studies

Mouse colitis models show significant histological improvement.

Wound Healing

Preliminary 5 studies

Anti-inflammatory effects facilitate wound healing in skin models.

Mechanism of Action

KPV binds to melanocortin receptors (MC1R, MC3R) expressed on immune cells and intestinal epithelial cells, inhibiting NF-kB activation and downstream inflammatory cytokine production (IL-1beta, IL-6, TNF-alpha). Its small size facilitates oral bioavailability — unusual for a peptide.

KPV reduces colitis severity through NF-kB inhibition

Overview

KPV’s primary appeal is its combination of potent gut anti-inflammatory activity and unusual oral bioavailability for a peptide. Most peptides are degraded in the gastrointestinal tract before absorption; KPV’s small size (tripeptide) and stability allow meaningful oral delivery, potentially simplifying administration for gut-targeted applications.

IBD Research

The animal data for IBD is promising — particularly in DSS-induced colitis models where KPV shows histological improvements, reduced inflammatory markers, and preserved intestinal architecture. The mechanistic rationale (NF-kB inhibition in gut epithelium) is sound. No human trials have been conducted.

Alpha-MSH Connection

KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH (alpha-melanocyte stimulating hormone), which has known anti-inflammatory properties. KPV retains this activity in a smaller, more stable, more bioavailable format — a classic peptide fragment optimization.

Research Priority

Of the “gut healing” peptides, KPV has one of the cleaner mechanistic profiles and one of the better arguments for oral delivery. It represents a genuine research opportunity, though the translation from animal models to human IBD remains to be demonstrated.
