KPV Mechanism of Action
How KPV works: receptor targets, signalling pathways, and molecular profile.
α-MSH Fragment Without the Pigmentation Effects
KPV is a synthetic tripeptide reproducing the C-terminal three residues (Lys-Pro-Val) of alpha-MSH, the parent hormone behind Melanotan II. Because it lacks the rest of the α-MSH sequence, KPV retains melanocortin-pathway anti-inflammatory signaling without triggering the skin-darkening or libido effects associated with full-length melanocortin agonists.
NF-κB Pathway Modulation
Preclinical research points to KPV suppressing NF-κB activation, a master transcription factor driving inflammatory cytokine production. This mechanism underlies most of its studied applications, gut inflammation (colitis models), skin inflammation, and general wound-healing support, though nearly all supporting data is preclinical or in-vitro rather than human clinical evidence.
