KPV
KPV is the C-terminal tripeptide (lysine-proline-valine) of the hormone α-MSH, corresponding to its positions 11–13. In cell and rodent models an inflammation-modulating activity has been described, primarily via inhibition of the NF-κB signalling pathway. The evidence is drawn almost exclusively from preclinical work (cell culture and mouse); controlled human studies are essentially absent. KPV is not an approved medicinal product.
Mechanism of action
KPV is the C-terminal fragment of α-melanocyte-stimulating hormone (α-MSH). In preclinical models the inflammation-modulating activity is attributed predominantly to inhibition of the NF-κB and MAP-kinase signalling pathways, accompanied by reduced release of pro-inflammatory mediators. Cellular uptake via the peptide transporter PepT1 has also been described. The precise molecular mechanisms are not conclusively understood and not confirmed in humans.

Calcolatore di ricostituzione
I peptidi arrivano come polvere secca. Una volta disciolti in un liquido (ricostituzione), questo calcolatore risponde a una sola domanda: quanta sostanza c'è in un millilitro di soluzione dopo?
- 1Inserisci la quantità di sostanza del flacone (riportata sull'etichetta).
- 2Inserisci quanto solvente aggiungi.
- 3Risultato = concentrazione in mg per mL.
