KPV
A tripeptide derived from alpha-MSH that retains potent anti-inflammatory activity through NF-kB suppression without causing skin pigmentation.
KPV (Lysine-Proline-Valine) is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH) that carries the majority of its anti-inflammatory properties. Unlike full-length alpha-MSH, KPV does not activate melanocortin receptors for pigmentation, making it a targeted anti-inflammatory agent. Research shows it is transported into cells via the PepT1 transporter, where it suppresses NF-kB and MAPK inflammatory cascades.
⚙️ Mechanism of Action
KPV enters cells via the hPepT1 peptide transporter rather than through melanocortin receptors, distinguishing its mechanism from other alpha-MSH-derived peptides. Once intracellular, it inhibits NF-kB nuclear translocation and MAPK signaling, suppressing the production of pro-inflammatory cytokines including TNF-alpha, IL-6, and IL-8. This PepT1-mediated pathway is particularly relevant in intestinal epithelial cells, making it a promising candidate for gut inflammatory conditions.
