Freselestat quarterhydrate

Freselestat quarterhydrate (ONO-6818 quarterhydrate) is a potent and orally active neutrophil elastase inhibitor with a K i of 12.2 nM. Freselestat quarterhydrate is >100-fold less-active against other proteases such as trypsin, protein-ase 3, pancreaticAppearance:SolidIC50& Target:Ki: 12.2 nM (Neutrophil elastase)In Vitro: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).
