About KPV Capsules

KPV is a potent tripeptide (Lys-Pro-Val) known for its strong anti-inflammatory properties. These oral capsules are designed for research into gastrointestinal health, immune modulation, and inflammatory signaling pathways without the hormonal side effects of the parent $\alpha$ -MSH molecule.

Mechanism of Action

The mechanism involves KPV entering the cell and interacting directly with signaling molecules to inhibit the NF-κB pathway. This effectively blocks the production of pro-inflammatory cytokines. In the gut, it research shows it helps maintain the protective barrier and reduces the inflammatory response in experimental models of colitis and skin irritation.

Frequently Asked Questions

What is the origin of KPV?

KPV is a tripeptide fragment derived from the C-terminal end of Alpha-Melanocyte Stimulating Hormone ($\alpha$-MSH).

Does KPV cause skin tanning?

No, unlike the full $\alpha$-MSH molecule, the KPV fragment does not possess melanotropic (tanning) activity.
