Freselestat
Based on 1 Customer Validation
Freselestat (ONO-6818) is a potent and orally active neutrophil elastase inhibitor with a Ki of 12.2 nM. Freselestat is >100-fold less-active against other proteases such as trypsin, protein-ase 3, pancreatic elastase, plasmin, thrombin, collagenase, cathepsin G, and murine macrophage elastase. Freselestat has a potent anti-inflammatory activity.

Biological Activity
Ki: 12.2 nM (Neutrophil elastase)[3]
Simulated extracorporeal circulation is established by recirculating fresh heparinized (3.75 U/mL) human blood for 120 minutes in a membrane oxygenator and a roller pump with and without 1.0 μM of Freselestat (ONO-6818). Neutrophil elastase levels are significantly lower in the Freselestat group. Freselestat significantly reduces interleukin 8 and C5b-9 production. Freselestat does not modulate changes of CD11b and L-selectin during recirculation[3].
