Research Comparison
KPV (Lys-Pro-Val) vs VIP (Vasoactive Intestinal Peptide)
A side-by-side research comparison of KPV (Lys-Pro-Val) and VIP (Vasoactive Intestinal Peptide) drawn from Cedar Peptides' peptide database records.
KPV (Lys-Pro-Val)
KPV (Lys-Pro-Val) is a tripeptide derived from the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH). Unlike the parent hormone, KPV retains potent anti-inflammatory and immunomodulatory activity without inducing melanogenesis or pigmentation. It has been investigated for its ability to modulate inflammatory pathways at the cellular level, with particular relevance to inflammatory bowel disease, dermatological conditions, and systemic inflammation. Its small size enables efficient cellular penetration and direct interaction with intracellular signaling pathways.
VIP (Vasoactive Intestinal Peptide)
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide with potent anti-inflammatory, immunomodulatory, and neuroprotective properties. Acting through VPAC1 and VPAC2 receptors, VIP regulates immune function, vascular tone, circadian rhythms, and neurological activity. VIP has been extensively studied in inflammatory, pulmonary, and neurological conditions. Intranasal delivery enables direct CNS access via olfactory and trigeminal pathways, while systemic administration influences immune and vascular systems. It is particularly notable in research involving chronic inflammatory response syndrome (CIRS), respiratory dysfunction, and neuroimmune regulation.
Reading a comparison
A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
