IndicationInvestigated for use/treatment in hepatitis (viral, C), liver disease, and transplantation (organ or tissue).
PharmacodynamicsNot Available
Mechanism of actionIDN-6556 significantly improves markers of liver damage in patients infected with the Hepatitis C virus (HCV), an infection that affects up to 170m patients worldwide. IDN-6556 represents a new class of drugs that protect the liver from inflammation and cellular damage induced by viral infections and other causes. Various studies have also shown that it significantly lowers aminotransferase activity in HCV patients and appeared to be well tolerated.

General Function:
Endopeptidase activity
Specific Function:
Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.

General Function:
Phospholipase a2 activator activity
Specific Function:
Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-|-Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspa...

General Function:
Cysteine-type peptidase activity
Specific Function:
Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-|-Gly-217' bond. Overexpression promotes programmed cell death.
