Product Information
KPV | Alpha-MSH C-terminal Tripeptide — Research Grade
KPV (alpha-MSH 11-13: Lys-Pro-Val) is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone. Despite its small size, it retains the anti-inflammatory signalling activity of the parent peptide and has been studied extensively in gut inflammation and wound healing models.
Mechanism of Action
- MC1R agonism — activates the melanocortin 1 receptor expressed on immune and epithelial cells
- NF-kB inhibition — suppresses the canonical inflammatory transcription factor intracellularly, independent of cell surface receptor binding
- Gut epithelial barrier — studied for restoration of tight junction integrity in leaky gut and IBD models
- Wound healing — promotes fibroblast proliferation and reduces pro-inflammatory cytokine expression at wound sites
Research Areas
KPV is studied in inflammatory bowel disease (IBD), Crohn disease models, colitis, gut permeability, and wound healing. Its tripeptide structure confers enhanced gut stability relevant to oral delivery research.
For Research Use Only. Rainbow Peptide supplies KPV exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
