caspase-8 inhibitor is a reversible inhibitor of caspase-6, -8 and granzyme B. It is also known to inhibit caspase-10. Ac-IETD-CHO is a chemical compound with the systematic name N-Acetyl-Ile-Glu-Thr-Asp-aldehyde. It is a synthetic peptide aldehyde derivative and belongs to the class of caspase inhibitors. Ac-IETD-CHO specifically inhibits caspase-8, an enzyme involved in programmed cell death, also known as apoptosis. By blocking caspase activity, Ac-IETD-CHO can interfere with apoptotic pathways and potentially modulate cell death processes. This compound is used in research and experimental studies to investigate the role of caspases and apoptosis in various biological systems.
