Mechanism of Action

Targets/IC₅₀/Ki	caspase
In vitro	Emricasan (IDN-6556), also called PF-03491390, is an inhibitor of activated caspases with sub- to nanomolar activity in vitro. It shows neuroprotective activity for hNPCs but does not suppress ZIKV replication.
In vivo	In the murine NASH model, stellate cell activation and hepatic fibrogenesis are attenuated by administration of Emricasan (IDN-6556), a pan-Caspase inhibitor. It decreases liver injury but not metabolic derangement in NASH and also ameliorates inflammation. This compound is currently being evaluated in phase 2 clinical trials for the reduction of hepatic injury and liver fibrosis caused by chronic HCV infection.
