KPV (Lys-Pro-Val) tripeptide C-terminal fragment of α-MSH, for in vitro anti-inflammatory and gut-mucosal research applications.
Every batch of KPV is sent to an accredited independent laboratory before it ships. Here is exactly what we screen for - and the certificate that proves it.
Anti-inflammatory tripeptide signaling characterized across NF-κB pathway, mast cell, and gut mucosal research models
KPV represents the C-terminal tripeptide of α-MSH (residues 11-13). In cell culture and in vivo IBD models, KPV reduces nuclear translocation of NF-κB and downregulates downstream pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8) by interfering with IκB degradation and p65 phosphorylation.
KPV demonstrates mast cell stabilizing activity in ex vivo and rodent skin/airway models. By restricting degranulation and histamine/tryptase release, KPV reduces local mediator-driven inflammation - a mechanism implicated in contact hypersensitivity and allergic-inflammation models.
Preclinical work using DSS- and TNBS-induced murine colitis models reports oral and rectal KPV reduces histological colitis scores, MPO activity, and pro-inflammatory cytokine expression. PepT1-mediated uptake into colonocytes is one proposed delivery route.
Reported findings from in vitro assays and rodent colitis models
Primary areas of KPV preclinical investigation
DSS- and TNBS-induced colitis murine models report oral or rectal KPV delivery reduces histological inflammation, MPO activity, and pro-inflammatory cytokine expression in colonic tissue. PepT1-mediated colonocyte uptake is the proposed route.
Kannengiesser et al. 2008 ↗In vitro studies in human colonic epithelial cells (HT-29, Caco-2) characterize KPV's ability to block NF-κB nuclear translocation and downregulate TNF-α, IL-1β, and IL-8 expression - useful for dissecting tripeptide-driven anti-inflammatory signaling.
Dalmasso et al. 2008 ↗As the C-terminal tripeptide of α-MSH (residues 11-13), KPV serves as a tool compound for probing melanocortin-receptor-dependent and -independent anti-inflammatory mechanisms, and for studying minimal α-MSH-derived sequences.
