Biological Activity

Ulinastatin is a broad-spectrum serine protease inhibitor that targets trypsin, chymotrypsin, and neutrophil elastase. It suppresses the activation of pro-inflammatory pathways, including NF-kB and MAPK signaling, thereby reducing the production and release of inflammatory cytokines such as TNF-α, IL-1β, and IL-6. Through these mechanisms, ulinastatin attenuates systemic inflammatory response, modulates apoptosis, and protects against organ damage in acute inflammatory conditions.
