KPV is the C-terminal tripeptide fragment of alpha-melanocyte stimulating hormone (α-MSH). Despite its small size, KPV retains anti-inflammatory properties of the parent molecule and has been studied for its effects on NF-κB signaling, pro-inflammatory cytokine release, and mast-cell activation.

KPV is investigated in inflammatory-bowel-disease research, skin inflammation models, and mast-cell activation studies. Its small size allows investigation of delivery routes not available to larger peptides.
