KPV

KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH). It is studied for its potent anti-inflammatory effects in the gut and skin without the pigmentation effects of full alpha-MSH.

Profile All prices

Role: Anti-inflammatory tripeptide. Alpha-MSH(11-13) fragment that suppresses NF-kB signaling and proinflammatory cytokines in mucosal and systemic inflammation models.
