KPV

KPV (Lysine-Proline-Valine) is a naturally occurring tripeptide representing the C-terminal fragment (amino acids 11-13) of alpha-melanocyte-stimulating hormone (alpha-MSH). Despite being only three amino acids long, KPV retains the anti-inflammatory properties of the full alpha-MSH molecule without its melanogenic (tanning) effects.

KPV exerts its anti-inflammatory effects primarily through inhibition of the NF-kB inflammatory signaling pathway. It enters cells and directly interacts with inflammatory signaling components, reducing the production of pro-inflammatory cytokines including TNF-alpha, IL-6, and IL-1beta. The peptide also inhibits the activation and nuclear translocation of NF-kB, a master regulator of inflammatory gene expression.

Research has demonstrated KPV's efficacy in reducing inflammation in various models, with particular focus on gastrointestinal inflammation. Studies in colitis models have shown significant reduction in inflammatory markers and tissue damage. Its small size allows for oral administration with retained bioactivity in the gut, making it particularly relevant for inflammatory bowel conditions. Additional research has explored its potential in skin inflammation, wound healing, and as an antimicrobial agent against Staphylococcus aureus and Candida albicans.
