Emricasan (IDN- 6556 or PF-03491390) (3-[2-[(2-tert-butyl-phenylaminooxalyl)-amino]-propionylamino]-4-oxo-5-(2,3,5,6-tetrafluoro-phenoxy)-pentanoic acid) is a pan-caspase inhibitor. Testing in vitro enzyme assays demonstrated that emricasan efficiently inhibits all human caspases at low nanomolar concentrations. Preclinically, emricasan was effective in inhibiting apoptosis of sinusoidal endothelial cells. Emricasan has marked efficacy in models of liver disease after oral administration and thus, is an excellent candidate for the treatment of liver diseases characterized by excessive apoptosis. This drug is a first-in-class anti-apoptotic caspase inhibitor with demonstrated preliminary efficacy in liver-impaired patients in humans.

Sample Use Guides

Double-blind, randomized, placebo-controlled, parallel-dose study in patients with chronic hepatitis C treated with placebo or Emricasan (IDN- 6556 or PF-03491390) (5, 25 or 50 mg) orally twice daily (b.d.) for up to 12 weeks.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: acute myeloid leukemia (AML) cells are sensitive to birinapant-induced death and that the clinical caspase inhibitor emricasan/IDN-6556 augments, rather than prevents, killing by birinapant. Deletion of caspase-8 sensitized AML to birinapant, whereas combined loss of caspase-8 and the necroptosis effector MLKL (mixed lineage kinase domain-like) prevented birinapant/IDN-6556-induced death, showing that inhibition of caspase-8 sensitizes AML cells to birinapant-induced necroptosis.
