Hodoodo CAT#: H319922

CAS#: 208848-19-5

Description: Freselestat, also known as ONO-6818, is a potent neutrophil elastase inhibitor. Freselestat reduces inflammatory mediators during simulated extracorporeal circulation. ONO-6818 significantly reduced interleukin 8 and C5b-9 production. ONO-6818 did not modulate changes of CD11b and L-selectin during recirculation.
