Product details
KPV — C-Terminal α-MSH Tripeptide
KPV is the C-terminal tripeptide of α-melanocyte-stimulating hormone, composed of lysine-proline-valine. Despite its minimal size, KPV retains the anti-inflammatory activity of the parent hormone while shedding the pigmentation and appetite-modulating effects that are driven by other regions of α-MSH. This separation of activities has made KPV a precision research tool for studying inflammation pathways in isolation.
Mechanism of Action
KPV suppresses NF-κB nuclear translocation and downstream pro-inflammatory cytokine expression, particularly TNF-α, IL-1β, and IL-6. Research has documented stabilization of mast cells, reduction in mast cell degranulation, and improvements in intestinal epithelial barrier integrity. The peptide appears to enter cells without requiring melanocortin receptor binding, positioning it as mechanistically distinct from the receptor-mediated actions of full-length α-MSH. Its compact size supports oral and topical administration studies.
