KPV
Also known as: Lysine-Proline-Valine, α-MSH(11–13)
A tiny three–amino-acid tail of the α-MSH hormone studied for anti-inflammatory effects, especially in the gut and skin — preclinical so far.
Last updated
Mechanism
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (α-MSH). It seems to carry much of α-MSH's anti-inflammatory activity without strongly affecting pigmentation. In cell and animal models it dampens pro-inflammatory signaling (notably NF-κB) inside immune and epithelial cells, and it can be taken up directly by intestinal cells, which is why gut inflammation is a major research focus.
What the research shows
KPV's anti-inflammatory effects are reproducible in vitro and in rodent models of colitis, and its small size and oral/topical absorption make it pharmacologically interesting. But the evidence stops at the preclinical stage: there are no published human RCTs establishing benefit for inflammatory bowel disease, skin conditions, or recovery. Treat the human case as plausible-but-unproven.
Benefits studied
- Reduced colonic inflammation in animal models of colitis
- Anti-inflammatory effects on immune and epithelial cells in vitro
- Wound-healing and antimicrobial activity in skin models
- Direct uptake by intestinal cells, supporting oral interest
Risks & unknowns
- No published human RCTs — clinical benefit is unproven
- Long-term human safety unknown
- Research-use-only sourcing; purity and dose vary
- Mechanistic overlap with a hormone pathway whose systemic effects are not fully characterized for this fragment
Regulatory status
Research compound. Sold "for research use only" — not approved for human consumption.
Goals studied: Gut healing, Skin anti-aging
FAQ
- What is KPV used for in research?
- Mostly inflammation — particularly gut inflammation like colitis — and some skin and wound applications, all at the preclinical stage.
- Can KPV be taken orally?
- In animal studies it is absorbed by intestinal cells, which is part of its appeal, but there are no human trials establishing an effective or safe oral dose.
